1. INTRODUCTION
Congratulations on your purchase of the Rocktron Chameleon™! The Chameleon™
is a 24 bit DSP professional guitar preamp providing 12 unparalleled effect
algorithms and superb sound quality never before heard from a digital guitar
preamp. Complete programmability and full MIDI implementation are coupled
with a user friendly operating format to ensure that designing unique and
useful preset sounds is as simple as possible.
In addition, the Chameleon™ also features:

Advanced Speaker Simulation provides a strikingly realistic approximation
of a miked speaker cabinet at line-level for direct mixer input or headphone
listening.

Full parametric Pre and Post EQ gives the user complete EQ control
over each preset.

Hush Systems’ HUSH® Noise Reduction provides noise reduction while
playing and complete silence when not.

“Variac” Simulation, like a conventional Variac, adjusts
the level at which the preamp begins to distort. This provides more gain
in high-gain applications, and allows for full-bodied cleaner presets which
just begin to distort when the strings are attacked harder.

Internal Wah-Wah allows the player to use an expression pedal for Wah-Wah
effects instead of running long audio cables out to a conventional Wah-Wah
pedal.

High-quality Digital Effects, including:

Reverb, Phasing, Tremolo, Flanging
Pitch Shifting, Compression, Chorus and Delay.

XLR Outputs for direct mixer input.

For a thorough explanation of the Chameleon and its features, please
read this manual carefully and keep it for future reference. After removing
the Chameleon™ from the box, save all packing materials in case it becomes
necessary to ship the unit.

2. FRONT PANEL
1 POWER switch
2 RECALL button
This button is used to recall the displayed preset.
3 PRESET control
This control scrolls through the successive presets.
4 CONFIG button/led
The status of this button determines whether the Chameleon™ will display
either the preset number and titlc or the configuration of the currently
displayed preset. The configuration display indicates the effects that
the displayed preset executes and, in most cases, the order in which they
are executed.
The LED above the CONFIG button is lit when the configuration is displayed.
5 DISPLAY panel
The DISPLAY panel provides 16 characters consisting of 14 segments
each.
6 EFFECT BYPASS button/led
When lit, the Pre and Post effects are bypassed and only the Compressor/Preamp
signal is passed to the Chameleon™ outputs This button does not affect
the condition of the Speaker Simulator.
7 COMPARE button
The COMPARE button may be used to compare an altered parameter value
to its stored value.
This button may also be used to compare between the altered and stored
values of multiple parameters under the same function heading (i.e. “Reverb”,
“Mixer”, etc.).

Note: If comparing an aItered value to the stored value and the stored
value is currently being viewed, turning a knob or pressing a button that
changes the parameter value displayed will cancel the previous altered
value. This will alao occur if a MIDI Control change is received while
viewing the stored value(s).

8 PARAMETER ADJUST control
This control is used to adjust a displayed parameter value. When the
parameter is changed from its original value, the LED above the STORE button
will light until either the new value is stored, a new preset is selected
or the parameter is returned to its original value.
9 STORE button/led
This button is used to store values into the Chameleon™ memory when
altered. See “Storing Changed Preset Parameters”
for more information on this procedure.
10 PARAMETER SELECT control
the available parameters under the current function heading. In the
“Title Edit” function, this control will scroll through the character
locations to be edited.
11 FUNCTION SELECT control
This control allows access to each function of the Chameleon™, depending
on what configuration is currently recalled.
12 SPEAKER SIMULATOR indicator
When lit, this LED indicatcs that the Speaker Simulator is activated
for the current preset.
13 OUTPUT LEVEL control
This control is used to adjust the output level of the unit at the
unbalanced outputs.
14 INPUT LEVEL meter
These LEDs provide visual indication of the peak level of the input
signal when in the Preset Select mode. For the optimal signal-to-noise
ratio, it is best to adjust the input level so that the last LED (0dB)
is rarely lit. This will guard against the possibility of overdriving the
unit.
These LEDs also display the final digital mixer output levels when
any other functions are selected. This will help you to guard against clipping
the output of the mixer at the digital-to-analog converter.
15 INPUT LEVEL control
This control adjusts the unit’s gain to match the signal level at the
input of the Chameleon. Use the INPUT LEVEL meter to determine the setting
of this control.
16 INPUT jack
This standard, unbalanced mono 1/4″ jack is used to provide input
to the unit. It is front panel mounted for easy access.

3. REAR PANEL
1 BALANCED OUTPUT LEVEL
control
This control determines the output level at the XLR BALANCED OUTPUTS.
Note that the balanced outputs pass the same signals as the unbalanced
outputs, except that the levels are independently adjustable.
2 (L) BALANCED OUTPUT connector
This balanced XLR connector provides the left balanced output of the
Chameleon™ for direct use into a mixing console.
3 (R) BALANCED OUTPUT connector
This balanced XLR connector provides the right balanced output of the
Chameleon™ for direct use into a mixing console.
4 (L) UNBALANCED OUTPUT jack
This 1/4″ unbalanced RTS jack provides the left unbalanced output
of the Chameleon™ for use with a guitar amplifier or rack system setup.
In addition, this jack also allows for the connection of stereo headphones
(600ohms impedance or greater).
5 (R) UNBALANCED OUTPUT jack
This 1/4″ unbalanced RTS jack provides the right unbalanced output
of the Chameleon™ for use with a guitar amplifier or rack system setup.
6 FOOTSWITCH jack
This 1/4″ mono jack allows for the connection of a momentary footswitch
to control the Tapped Delay feature of the Chameleon™. The Tapped Delay
feature allows the player to set (or reset) the current delay time by tapping
the footswitch. The new delay time will be based on the length of time
between two taps. For more information on this feature, refer to the “Tap
Delay” section .
7 REMOTE jack
This 7-pin DIN connector is provided for the connection of a Rocktron
All Access™ MIDI footswitch, which can be configured to act as a dedicated
remote footswitch for the Chameleon™. This feature allows the user to access
Chameleon™ functions and parameters via the remote footswitch.
8 PHANTOM POWER jack
This 2.5mm PIN jack offers the ability to power Rocktron MIDI foot
controllers from a 7-pin MIDI cable which connects from the Rocktron MIDI
foot controller to the MIDI IN jack on the rear panel of the Chameleon™.
This eliminates the need to find an AC outlet near where the footpedal
would be placed during a performance, or the need to run an extension cord
out to the footswitch. Instead of inserting the AC adaptor into the “POWER”
jack of the footswitch as you would normally, plug it into the “PHANTOM
POWER” jack on the Chameleon™. This will power the Rocktron MIDI foot
controller through pins 6 and 7 of the MIDI cable connecting the two units.
A 7-pin MIDI cable must be used and is available from your Rocktron dealer.
9 MIDI IN jack
This 7-pin DIN connector must be connected to the MIDI OUT jack of
the transmitting MIDI device via a standard MIDI cable, or to the MIDI
THRU jack of the preceding device (if the Chameleon™ is within a chain
of MIDI devices).
Pins 6 and 7 of this connector carry the phantom power to power a Rocktron
MIDI foot controller when a 7-pin MIDI cable is used.
10 MIDI THRU/OUT jack
This standard 5-pin DIN connector can be connected to the MIDI IN jack
of another device via a standard MIDI cable. There are limitations to the
number of devices that can be chained (or series connected) in this fashion.

Note: Inherently in MIDI there is a limit to the number of devices
which can be chained together (connected in series). With more than 3 devices,
a slight distortion of the MIDI signal can occur (due to signal degradation)
which can cause an error in MIDI signal transmission. Should this problem
arise, a MIDI Thru box can be used which connects directly to the MIDI
device which transmits MIDI information and has multiple connectors for
the multiple devices receiving MIDI. MIDI cables should not exceed 50 feet
(15 meters) in length.

11 POWER jack
This 4-pin DIN connector accepts power from the 9VAC adaptor supplied
with the unit.

5. OPERATING FORMAT
The Chameleon™ provides 254 stored sounds called presets Any of the
254 presets can be called up at any time via the front panel PRESET control
(used to select a preset) and RECALL button (used to call up the selected
preset), or by a remote MIDI footswitch.
The root of each preset’s sound is its confgurafion. The configuration
determines both the effects available for a given preset and the order
in which those effects are executed. The Chameleon™ provides 12 fixed configurations
to achieve a wide array of preset sounds, any of which may be instantly
called up at any time.
VooDu Chameleon™ Configurations:

High-gain Distortion – Chorus – Delay – Reverb
High-gain Distortion – Flange – Delay – Reverb

To see the configuration of each preset, press the CONFIG button on
the front panel of the Chameleon™ – the LED above the CONFIG button will
light and the display will show the configuration for the current preset.
Turning the PRESET control will then scroll through each successive preset
(displaying its configuration instead of its preset number and title)
The configuration of each preset can also be changed from within the
desired preset. For more information on selecting a configuration, see
“Selecting a Configuration” in “Operating
the Chameleon™”.

Chameleon™ Functions and
Parameter Descriptions
Each Chameleon™ preset is divided up into individual blocks called
functions (such as “Mixer”, “Reverb”,
etc.). Within each function of each configuration is a set of controls
which allow you to manipulate various aspects of that function. These controls
are called parameters. It is the setting of each of the parameters
which determines the overall sound of each preset.
The Chameleon™ is set up to allow you to first access each function
(via the FUNCTION SELECT control), then the parameter list for each function
(via the PARAMETER SELECT control) and finally the adjustable value for
each parameter (via the PARAMETER ADJUST control).

The functions available for each preset are dependent upon which configuration
is currently recalled. The remainder of this section will describe each
of the effect-based functions and the associated adjustable parameters
they provide.
The remaining functions are utility-based, and are described in “Operating
the Chameleon™”.
Back to CONTENTS

GLOBAL Function
The first function displayed after turning the FUNCTION SELECT control
is the Global function. The parameters provided in this function affect
all presets (i.e. the settings stored for these parameters are the same
for all presets).
The PARAMETER SELECT control will allow you to access these Global
parameters:
OUTPUT
The OUTPUT parameter determines whether the output of the Chameleon™
is a stereo (left and right) signal or two mono signals.
SPKR SIM
This SPEAKER SIMULATOR parameter under the Global function allows you
to globally (all presets) lock the Speaker Simulatoroff (LOCKOFF) so that
it will always be off for all presets – regardless of the status of the
“SPKR SIM” parameter under the Speaker Simulator function. It
may also be locked on for the left channel (LOCK L) or on for both channels
(LOCK B).

Note: The Chameleon™ will only recognize the “SPKR SIM”
parameter under the Speaker Simulator function when this parameter is stored
as UNLOCK.

HUSH® OFFSET
The HUSH® OFFSET parameter allows you to globally (all presets)
adjust the HUSH® Expander Threshold. This means that if this parameter
is altered from 0dB to +3dB, the Expander Threshold will be 3dB higher
for all presets. This feature can be useful when switching from a quiet
guitar with passive electronics to a noisy guitar with active electronics
– as the active guitar would require a higher Threshold level in all presets.
MUTE
The MUTE parameter allows you to mute the output of the Chameleon™.
This feature is especially useful when changing guitars during a live set.
If a Rocktron All Access™ is used in remote mode with the Chameleon™, a
single All Access™ button can be configured as a momentary switch which
will mute the output when it is held down. (See “Using a Chameleon™
with a Rocktron All Access™ in REMOTE mode”.)

FUNCTION PARAMETER LIST RANGE

GLOBAL OUTPUT (Output Level) Stereo, Mono
SPKR SIM (Speaker Simulator Lock) Unlock, Lock Off, Lock L, Lock B
HUSH® OFFSET -10 dB to +30 dB
MUTE Off, on

MIXER Function
The next function displayed after turning the FUNCTION SELECT control
is the Mixer function. The Mixer function parameters are included in all
presets – regardless of which configuration is currently recalled – although
the parameter values stored in this function are only for the currently
recalled preset.
This digital mixer allows you to control most signal levels pertaining
to each preset’s configuration and stores these levels for each preset.
The PARAMETER SELECT control will allow you to access these Mixer
parameters:
VOLUME
The VOLUME parameter determines the overall signal level of the current
preset.
LEFT OUT LVL
The LEFT OUT LEVEL parameter allows you alter the level of the left
channel output of the current preset independent of the right channel.
RIGHT OUT LVL
The RIGHT OUT LEVEL parameter allows you alter the level of the right
channel output of the current preset independent of the left channel.
MIX DIR/EFF
The DIR/EFF MIX parameter is used to define the ratio of direct signal
level to effect (Chorus, Flange, Pitch Shift) signal level.
DIR PAN
The DIRECT PAN parameter allows you to pan the direct signal to the
left or right.
DELAY LVL
The DELAY LEVEL parameter determines the overall level of the delayed
signal at the output relative to the direct signal and other effect signals.
This parameter can also be accessed from the Delay function parameter list.
REVERB LVL
The REVERB LEVEL parameter determines the level of the reverb signal
at the output relative to the direct signal and other effect signals. This
parameter can also be accessed from the Reverb function parameter list.

FUNCTION PARAMETER LIST RANGE

MIXER VOLUME (Volume Level) 0 to 127
LEFT OUT LVL (Left Channel Output Level) -oo to +6dB
RIGHT OUT LVL (Right Channel Output Level) -oo to +6dB
MIX (Direct/Effcct Mix Level) DIR <0 to 100> EFF
DIR PAN (Direct Signal Panning) L <0 to 100> R
DELAY LVL (Delay Signal Level) -oo to +0dB
REVERB LVL (Reverb Signal Level) -oo to +6dB

HIGH GAIN Function
The HIGH GAIN function is only accessible in configurations which display
“H-GAIN” in the configuration title. The preamp stage in these
configurations is set up to provide high gain levels for maximum sustain
and distortion.
The PARAMETER SELECT control will allow you to access these High
Gain parameters:
GAIN
The GAIN parameter determines the gain value in the distortion stage.

VARlAC ADJUST
The VARIAC ADJUST parameter adjusts the level at which the preamp stage
in the Chameleon™ begins to distort. A Variac is a voltage attenuating
device that plugs into an AC wall outlet and adjusts the voltage level
to any device which is plugged into it. For years, many guitarists have
plugged their amplifier heads into a Variac and reduced the voltage coming
into the amplifier from the AC wall outlet. This allows the amplifier tubes
to reach saturation at a lower input level and increases the gain produced.
The VARIAC ADJUST parameter operates in a similar manner as a conventional
Variac – where lowering the parameter value lowers the level at which saturation
will take place.
BASS LVL
The post BASS LEVEL parameter adjusts the amount of low frequency information
at the output of each preset. This parameter is also accessible from the
“Post EQ (Expert)” function. (In the Post EQ function, the center
frequency and bandwidth of this EQ section are also adjustable.)
MID LVL
The post MID LEVEL parameter adjusts the amount of mid frequency information
at the output of each preset. This parameter is also accessible from the
“Post EQ (Expert)” function. (In the Post EQ function, the center
frequency and bandwidth of this EQ section are also adjustable.)
TREBLE LVL
The post TREBLE LEVEL parameter adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible
from the “Post EQ (Expert)” function. (In the Post EQ function,
the center frequency and bandwidth of this EQ section are also adjustable.)
PRESENCE LVL
The post PRESENCE LEVEL parameter also adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible
from the “Post EQ (Expert)” function. (In the Post EQ configuration,
the center frequency and bandwidth of this EQ section are also adjustable.

FUNCTION PARAMETER LIST RANGE

HIGH GAIN GAIN (Gain Level) 12dB to 78dB
VARIAC ADJUST (Variac Level Adjustment) -6dB to 0dB
BASS LVL (Post Bass Level) -15dB to +15dB
MID LVL (Post Midband Level) -15dB to +15dB
TREBLE LVL (Post Treble Level) -15dB to +15dB
PRESENCE LVL (Post Presence Level) -15dB to +15dB

Back to CONTENTS
LOW GAIN Function
The LOW GAIN function is only accessible in configurations which display
“L-GAIN” in the configuration title. The preamp stage in these
configurations provides four distortion types, and can also be used for
clean tones.
The PARAMETER SELECT control will allow you to access these Low
Gain parameters:
GAIN
The GAIN parameter determines the gain value in the distortion stage.
DIST
The DISTORTION TYPE parameter allows you to select between four different
distortion types – Solid State, Pentode, Triode A and Triode B. The Solid
State setting provides the hardest clipping, while the Pentode type provides
a softer clipping and the Triode A and B types provide the softest clipping.
Triode A emulates a triode tube operating in Class A, with non-symmetrical
clipping – and therefore more even harmonics produced. Triode B emulates
a pair of triode tubes operating in Class B, with symmetrical clipping.
The differences between these types are most pronounced at moderate gain
settings of about 30dB or less, where Triode B produces the least amout
of upper harmonics.
BASS LVL
The post BASS LEVEL parameter adjusts the amount of low frequency information
at the output of each preset. This parameter is also accessible from the
“Post EQ (Expert)” function. (In the Post EQ function, the center
frequency and bandwidth of this EQ section are also adjustable.)
MID LVL
The post MID LEVEL parameter adjusts the amount of mid frequency information
at the output of each preset. This parameter is also accessible from the
“Post EQ (Expert)” function. (In the Post EQ function, the center
frequency and bandwidth of this EQ section are also adjustable.)
TREBLE LVL
The post TREBLE LEVEL parameter adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible
from the “Post EQ (Expert)” function. (In the Post EQ function,
the center frequency and bandwidth of this EQ section are also adjustable.)
PRESENCE LVL
The post PRESENCE LEVEL parameter also adjusts the amount of high frequency
information at the output of each preset. This parameter is also accessible
from the “Post EQ (Expert)” function. (In the Post EQ configuration,
the center frequency and bandwidth of this EQ section are also adjustable.)

FUNCTION PARAMETER LIST RANGE

LOW GAIN GAIN (Gain Level) 0dB to 48dB
DIST (Distortion type) Solid State, Pentode, Triode A, Triode B
BASS LVL (Post Bass Level) -15dB to +15dB
MID LVL (Post Midband Level) -15dB to +15dB
TREBLE LVL (Post Treble Level) -15dB to +15dB
PRESENCE LVL (Post Presence Level) -15dB to +15dB

Back to CONTENTS
HUSH® Function
The HUSH® function is accessible in all presets – regardless of
the configuration currently recalled.
HUSH® is Hush Systems’ patented single-ended noise reduction system.
The HUSH® system contained in the Chameleon™, though modeled after
the latest analog HUSH® design, is a fully digital implementation achieved
through Digital Signal Processing (DSP).
The low level expander of the HUSH® system operates like an electronic
volume control. The analog version of the HUSH® utilizes a voltage-controlled
amplifier (VCA) circuit which can control the gain between the input and
the output from unity to 30, 40 or even 50dB of gain reduction. When the
input signal is above the user preset threshold point, the VCA circuit
remains at unity gain. (This means that the amplitude of the output signal
will be equal to that of the input signal.) As the input signal level drops
below the user preset threshold point, downward expansion begins. At this
point the expander acts like an electronic volume control and gradually
begins to decrease the output signal level relative to the input signal
level. As the input signal drops further below the threshold point, downward
expansion increases. A drop in the input level by 20dB would cause the
output level to drop approximately 40dB (i.e., 20dB of gain reduction).
in the absence of any input signal, the expander will reduce the gain so
that the noise floor becomes inaudible.

The HUSH® circuit is located after the A/D converter in the signal
chain to reduce any noise generated from the guitar and the A/D converter.
This ensures a quiet input signal to the preamp section. Because the preamp
section of the Chameleon™ is digital, it is virtually noise-free (even
in the high-gain mode). Therefore, a quiet input signal to the preamp will
result in a quiet output signal.
The PARAMETER SELECT control will allow you to access these Hush
parameters:
HUSH I/O
The HUSH I/O parameter simply determines whether the HUSH® circuit
is active for the current preset.
HUSH® THRESH
The HUSH® THRESHOLD parameter determines the level at which downward
expansion begins. For example, if the HUSH® THRESHOLD was set at -20dB
and the input signal dropped below -20dB, downward expansion would begin.

FUNCTION PARAMETER LIST RANGE

HUSH® HUSH® (Hush In/Out) Out, In
EXP THRESH (Expander Threshold Level) -90dB to -27dB

PRE EQ (EXPERT) Function
The PRE EQ (EXPERT) function is available in all presets – regardless
of which configuration is currently recalled.
This function allows you to shape the tone prior to the distortion
stage. Considerable tone variations can be achieved by modifying these
pre-distort EQ parameters.
The PARAMETER SELECTcontrol will allow you to access these PRE
EQ parameters:
LF LEVEL
The pre-LF (low frequency) LEVEL parameter allows you to cut or boost
the low frequencies from – 15dB to +6dB prior to the distortion stage.
This EQ section is a shelving-type.
LF FREQ
The pre-LF (low frequency) FREQUENCY parameter allows you to select
a frequency band with an upper frequency between 63Hz and 500Hz to be cut
or boosted by the pre-LF LEVEL parameter.
MID LEVEL
The pre-MID LEVEL parameter allows you to cut or boost the mid-band
frequencies from -15dB to +12dB prior to the distortion stage.
MID FREQ
The pre-MID FREQUENCY parameter allows you to select a mid-band center
frequency between 500Hz and 4KHz to be cut or boosted via the pre-MID LEVEL
parameter.
MID BW
The pre-MID BANDWIDTH parameter determines how wide or narrow the bandwith
of the selected mid-band frequency is (in octaves). A small bandwidth only
boosts or cuts frequencies close to the center frequency, while a large
bandwidth affects the level of frequencies up to two octaves from the center
frequency.

FUNCTION PARAMETER LIST RANGE

PRE EQ LF LEVEL (Pre Low Frequency Level) -15dB to +6dB
(EXPERT) LF FRBQ (Pre Low Frequency Select) 63Hz to 500Hz
MID LEVEL (Pre Midband Level) -15dB to +12dB
MID FREQ (Pre Mid Frequency Select) 500Hz to 4kHz
MID BW (Pre Mid Bandwidth) 0.2 to 2.0 octaves

Back to CONTENTS
POST EQ (EXPERT) Function
The POST EQ (EXPERT) function is available in all presets – regardless
of which configuration is currently recalled.
This function allows you shape the tone after it has passed through
the distortion stage. These post-distortion EQ parameters have a more dramatic
effect on the overall tone than the pre-distortion parameters.
The PARAMETER SELECT control will allow you to access these POST
EQ parameters:
BASS LVL
The post-BASS LEVEL parameter allows you to cut or boost the low frequencies
by 15dB after the distortion stage.
BASS FREQ
The post-BASS FREQUENCY parameter allows you to select a center frequency
between 63Hz and 500Hz to be cut or boosted by the post- BASS LEVEL parameter.
BASS BW
The post-BASS BANDWIDTH parameter determines (in octaves) the width
of the selected bass band.
MID LVL
The post-MID LEVEL parameter allows you to cut or boost the mid-band
frequencies by 15dB after the distortion stage.
MlD FREQ
The post-MID FREQUENCY parameter allows you to select a mid-band center
frequency between 250Hz and 2KHz to be cut or boosted via the post-MID
LEVEL parameter.
MID BW
The post-MID BANDWIDTH parameter determines (in octaves) the width
of the selected mid-band.
TREBLE LVL
The post-TREBLE LEVEL parameter allows you to cut or boost the high-band
frequencies by 15dB after the distortion stage.
TREBL FRQ
The post-TREBLE FREQUENCY parameter allows you to select a high-band
center frequency between 1KHz and 8KHz to be cut or boosted via the post-TREBLE
LEVEL parameter.
TREBLE BW
The post-TREBLE BANDWIDTH parameter determines (in octaves) the width
of the selected high band.
PRESENCE LVL
The post-PRESENCE LEVEL parameter allows you to cut or boost another
high-band frequency by 15dB after the distortion stage.
PRES FREQ
The post-PRESENCE FREQUENCY parameter allows you to select a high-band
center frequency between 2KHz and 8KHz to be cut or boosted via the post-PRESENCE

COMPRESSOR Function
The COMPRESSOR function is available only in configurations which display
“L-GAIN” in the configuration title.
This function allows you to compress the signal prior to the distortion
stage. Compression is often used to maintain an even level when using clean
tones, and also to increase sustain when using distorted tones.
The PARAMETER SELECT control will allow you to access these COMPRESSOR
parameters:
COMPRESSOR I/0
The COMPRESSOR IN/OUT parameter determines whether the compressor is
active for the current preset.
COMP THRESH
The COMPRESSOR THRESHOLD parameter determines the input level (in dB)
at which compression will begin. Lower settings of this parameter will
result in more compression.
COMP ATTACK
The COMPRESSOR ATTACK parameter determines the speed (in milliseconds)
in which the compressor will reach its maximum compression level after
the input signal has exceeded the threshold level (set by the COMPRESSOR
THRESHOLD parameter).
COMP RELEASE
The COMPRESSOR RELEASE parameter determines the speed in which compression
will cease after the input signal has dropped below the threshold level.

FUNCTION PARAMETER LIST RANGE

COMPRESSOR COMPRESSOR (Compressor In/Out) Out,In
COMP THRESH (Compressor Threshold Level) -24dB to 0dB
COMP ATTACK (Compressor Attack Time) 1ms to 75ms

SPEAKER SIMULATOR Function
The SPEAKER SIMULATOR function is included in all presets and provides
a realistic approximation of a miked speaker cabinet for applications involving
connecting the Chameleon™ directly to a mixing board, recording system
or other full range system.
When a preset is recalled which has the Speaker Simulator on for either
the left channel or both channels, the front panel SPKR SIM LED will light.

Note: The parameters provided in this function are operational only
when the SPKR SIM parameter under the GLOBAL FUNCTION is stored UNLOCK,
LOCK L or LOCK B.

The PARAMETER SELECT control will allow you to access these SPEAKER
SIMULATOR parameters:
SPKR SIM I/O
The SPEAKER SIMULATOR parameter allows you to select whether the Speaker
Simulator is on for BOTH outputs, on for only the LEFT output or OFF.
SPKR TYPE
The SPEAKER TYPE parameter determines the type of speaker to be simulated.
15″,12″,10″, 8″ and full range speakers are available.
MIC PLACEMENT
The MIC PLACEMENT parameter simulates a microphone placed anywhere
from the center of the speaker cone out to the edge of the cone. Positive
parameter values simulate moving the microphone toward the center of the
speaker, while negative values move it to the edge.
REACTANCE
The REACTANCE parameter simulates the characteristics of the the interaction
between a tube amplifier and a guitar speaker cabinet. The higher the parameter
value selected, the more these characteristics will be apparent. Negative
values of reactance can be used to simulate an open-back cabinet.

WAH-WAH Function
The WAH-WAH function is available only in configurations which display
“WAH” in the configuration title.
The Chameleon™ has an internal wah-wah which allows for an expression
pedal to be used as a wah-wah pedal through continous Control changes.
Use of this feature eliminates the need to run long audio cables out to
a conventional wah-wah pedal.
To use an expression pedal as a wah-wah pedal, connect it to a MIDI
controller (such as a Rocktron MIDI Matetm)
and set the controller’s MIDI channel to correspond with the Chameleon™’s
receiving MIDI channel. Then set the pedal’s control number on the MIDI
Matetm to match the Wah Frequency parameter’s
control number on the Chameleon™. This control number is set on the Chameleon™
in the “CONTROLLER ASSIG” function. (See “Controller
Assignments” for more information on assigning control numbers.)
The PARAMETER SELECT control will allow you to access these WAH-WAH
parameters:
WAH-WAH I/O
The WAH-WAH I/O parameter determines whether the wah-wah is active
for the current preset.
WAH FREQ
The WAH FREQUENCY parameter allows you to manually sweep the frequency
range of the wah-wah via the PARAMETER ADJUST control. Selecting a frequency
for this parameter and storing the WAH-WAH parameter IN allows you to use
the wah-wah as a fixed wah.

PHASER Function
The PHASER function is available only in configurations displaying
“PHAS” in the configuration title.
Phase shifting involves splitting the input signal into two signals,
then shifting the phase of different frequencies of one signal and mixing
it back with the original signal.
The PARAMETER SELECT control will allow you to access these PHASER
parameters:
PHASER I/O
The PHASER IN/OUT parameter determines whether the Phaser is active
for the current preset.
DEPTH
The DEPTH parameter determines the modulation depth of the phase shift
effect. Higher parameter settings result in the sweep of the filtering
effect occurring over a wider frequency range.
RATE
The RATE parameter determines the speed at which the phase shifted
signal is modulated.
RESONANCE
The RESONANCE parameter adds feedback to the Phaser so that it has
a more pronounced effect.
STAGES
The STAGES parameter determines how many stages of phase shift are
to be active. A parameter setting of “4” produces a result similar
to a vintage Phase 90, while a setting of “6” emulates other
phaser pedals.

FUNCTION PARAMETER LIST RANGE

PHASER PHASER (Phaser In/Out Status) Out,ln
DEPTH (Amount of Modulation) 0 to 100

FLANGER Function
The FLANGER function is available only in configurations displaying
“FLAN” in the configuration title.
Flanging involves splitting the input signal into at least two individual
de- layed signals (Voice 1 and voice 2), then modulating these delayed
signals so that, when summed back with the direct signal, phase cancellations
will occur at some frequencies while peaks in the response will occur at
others.
The PARAMETER SELECT control will allow you to access these FLANGER
parameters:
FLANGER I/O
The FLANGER IN/OUT parameter determines whether the Flanger is active
or bypassed for the current preset.
LEVEL 1
The LEVEL 1 parameter determines the volume of Voice 1 relative to
Voice 2.

Tip: Keep the settings of these levels high and use the DIR/EFF mix
parameter in the Mixer function to control the overall amount of flanged
signal.

PAN 1
The PAN 1 parameter allows you to pan Voice 1 to the left or right
channel.
DEPTH 1
The DEPTH 1 parameter adjusts the amount of modulation of Voice 1 .
Lower DEPTH settings produce more subtle effects, while higher settings
will result in a more drastic effect.
RATE 1
The RATE 1 parameter determines the speed at which Voice 1 is modulated.
LEVEL 2
The LEVEL 2 parameter determines the volume of Voice 2 relative to
Voice 1.
PAN 2
The PAN 2 parameter allows you to pan Voice 2 to the left or right
channel.
DEPTH 2
The DEPTH 2 parameter adjusts the amount of modulation of Voice 2.
Lower DEPTH settings produce more subtle effects, while higher settings
will result in a more drastic effect.
RATE 2
The RATE 2 parameter determines the speed at which Voice 2 is modulated.
REGEN
The REGENERATION parameter determines how much of the the delayed output
signal is fed back into the input. More regeneration produces a more pronounced
“jet airplane” type of effect.

PITCH SHIFT Function
The PITCH function is available only in configurations displaying “PSHF”
in the configuration title.
Pitch Shifting is used to change the pitch of the input signal to produce
a harmony note based on the input signal. The harmony voice may be of any
fixed interval – up to one octave above the input signal to two octaves
below – and is selected in 20-cent increments. Fine adjustment can be made
in one cent (1/ 100th semitone) increments.
The PARAMETER SELECT control will allow you to access these PITCH
SHlFT parameters:
PITCHSHIFT I/O
The PITCH SHIFT IN/OUT parameter determines whether the Pitch Shifter
is active or bypassed for the current preset.
LEVEL
The LEVEL parameter determines the volume of the pitch shifted signal.
The DlR/EFF MIX parameter in the Mixer function also affects this volume.
PAN
The PAN parameter allows you to pan the shifted signal to the left
or right channel.
PITCH
The PITCH parameter selects what harmony note the Chameleon™ will produce
based on the input note. The value displayed for this parameter represents
the number of cents that the signal will be shifted (adjustable in 20-cent
increments). Each 100 cents (or five 20-cent steps) above or below “0”
represents the number of half-steps the shifted signal will be from the
input signal.
This parameter is adjustable from “-2400” to “+1200”,
where “-2400” = two octaves below the input signal, “0”
= unison and “+1200′ = one octave above the input signal. Refer to
the table below to determine the cent value for each fixed interval.
FINE
The FINE parameter allows for adjustment in 1-cent steps for fine adjustment
of the harmony note
SPEED
The SPEED parameter determines the amount of time delay used in the
shifting process. SLOW results in the longest delay and the highest quality
shifted signal (especially at larger amounts of pitch shift), FAST results
in the least delay, but the lowest quality shifted signal. This setting
should only be used for slight amounts of pitch shift.

CHORUS Function
The CHORUS function is available only in configurations displaying
“CRS” in the configuration title.
The Chorus effect in the Chameleon™ is produced by using two delayed
signals (Voice 1 and Voice 2), detuning these delayed signals (slightly
changing their pitch), then modulating the detune effect so that the amount
of pitch detune is constantly varying. Using different detune amounts,
modulation rates, modulation depths and pan settings for each delayed signal
will produce a greater perceived spaciousness.
The PARAMETER SELECTcontrol will allow you to access these CHORUS
parameters:
CHORUS I/O
The CHORUS I/O parameter determines whether the Chorus is active or
bypassed for the current preset.
LEVEL 1
The LEVEL 1 parameter determines the volume of Voice 1 in relation
to Voice 2. The DIR/EFF MIX parameter in the Mixer function also determines
the Chorus level.
PAN 1
The PAN 1 parameter allows you to pan Voice 1 to the left or right
channel.
DEPTH 1
The DEPTH 1 parameter adjusts the amount of modulation of the Voice
1 signal. A lower depth setting will produce a more subtle detune effect,
while a higher setting will produce a more extreme detuning of Voice 1
.
RATE 1
The RATE 1 parameter determines the sweep speed (or the speed at which
Voice 1 is modulated). Lower parameter settings will result in slower speeds,
while higher settings will result in faster speeds.
DELAY 1
The DELAY 1 parameter allows you to select the minimum delay time (in
milliseconds) for Voice 1. This delayed signal (along with Voice 2) is
detuned and modulated to produce the chorus effect. Using shorter delay
times will result in a tighter sounding chorused signal, while longer delay
times will produce a larger ambient effect.
LEVEL 2
The LEVEL 2 parameter determines the volume of Voice 2 in relation
to Voice 1 .
PAN 2
The PAN 2 parameter allows you to pan Voice 2 to the left or right
channel.
DEPTH 2
The DEPTH 2 parameter adjusts the amount of modulation of the Voice
2 signal. A lower depth setting will produce a more subtle detune effect,
while a higher setting will produce a more extreme detuning of Voice 2.
RATE 2
The RATE 2 parameter determines the sweep speed (or the speed at which
Voice 2 is modulated). Lower parameter settings will result in slower speeds,
while higher settings will result in faster speeds.
DELAY2
The DELAY 2 parameter allows you to select the minimum delay time (in
milliseconds) for Voice 2. It is this delayed signal (along with Voice1)
that is detuned and modulated to produce the chorus effect Using shorter
delay times will result in a tighter sounding chorused signal, while longer
delay times will produce a larger ambient effect.

DELAY Function
The DELAY function is available in all presets.
Delay is a reproduction of the input signal, occurring at a prescribed
time (usually expressed in milliseconds) following the input signal. The
Chameleon™ provides two discrete delays (Delay 1 and Delay 2), each of
which has its own parameters to determine its particular characteristics.
The PARAMETER SELECT control will allow you to access these DELAY
parameters:
DELAY
The DELAY parameter determines whether the Delay is active or muted for
the current preset.
MUTE TYPE
The MUTE TYPE parameter allows for muting the delay at its input (PRE),
its output (POST) or BOTH.
Muting the input (PRE) of the delay will not allow any signal to enter
the delay section until the delay is switched in. When using a moderate
amount of regeneration, switching out the delay with the input muted will
allow you to generate a non-delayed signal which will play over the decaying
regenerated signal which continues on after the delay is switched out.
Muting the output (POST) of the delay will result in the delayed signal
being immediately turned off when the delay is switched out. This means
that delays and regeneration will not continue when the delay is switched
out. If the output were not muted, signals that were input before the delay
was switched out would be allowed to regenerate, even after switching out
the delay.
It is also possible to mute both the input and the output (BOTH) so
that no signal enters or exits the Delay section when it is not switched
in.
DELAY LVL
The DELAY LEVEL parameter determines the overall level of the delayed
signal at the output relative to the direct signal and other effect signals.
This parameter can also be accessed from the Delay function parameter list.
MIX
The MIX parameter is used to define the ratio of Source 1 signal to
Source 2 signal to be input to the Delay section. Source 1 is the Voice
1 output frorn the previous effect in the signal chain (chorus, flanger,
pitch shifter, etc.), while Source 2 may be the Voice 2 output from the
previous effect in the signal chain or the direct signal (selectable via
the SOURCE 2 parameter).
In configurations where there is no effect immediately preceding the
delay, Source 1 and Source 2 will be the preamp output (direct) signal.
SOURCE 2
The SOURCE 2 parameter is used to select whether the Source 2 input
will be the VOICE 2 output from the previous effect in the signal chain
or the direct signal (DIR).
DLY HF DAMP
The DELAY HIGH FREQUENCY DAMPING parameter controls the amount of high
frequency content in the delayed and regenerated signals. Higher amounts
of damping will result in less high frequency information in the delayed
signal.
OUT LEVEL 1
The OUTPUT LEVEL 1 parameter determines the volume of Delay 1 in relation
to Delay 2.
PAN 1
The PAN 1 parameter allows you to pan the Delay 1 signal to the left
or right channel.
DLY TIME 1
The DELAY TIME 1 parameter determines the length of time (in milliseconds)
after the input signal that the Delay 1 signal will begin. The DELAY TIME
can be adjusted via the ADJUST control, MIDI controller changes or via
the Tap Delay feature (see “Operating the Chameleon”
for detailed descriptions of each).
REGEN 1
The REGENERATION 1 parameter determines the number of times the Delay
1 signal will repeat itself. This is achieved by feeding the delayed output
back into the input. Higher parameter settings will result in more repeats.
The displayed value represents the attenuation (in dB) that the regeneration
signal is subjected to at each repeat.
OUT LEVEL 2
The OUTPUT LEVEL 2 parameter determines the volume of Delay 2 in relation
to Delay 1.
PAN2
The PAN 2 parameter allows you to pan the Delay 2 signal to the left
or right channel.
DLY TIME 2
The DELAY TIME 2 parameter determines the length of time after the
input signal that the Delay 2 signal will begin. This length of time is
measured in milliseconds.
REGEN 2
The REGENERATION 2 parameter determines the number of times the Delay
2 signal will repeat itself. This is achieved by feeding the delayed output
back into the input. Higher parameter settings will result in more repeats.
* The Delay features a regeneration limter, since setting both REGEN
parameters to high levels would result in louder and louder echos until
a severe overload occurs. The limiter senses when this condition would
occur and automatically turns down both REGEN levels to avoid such an instability.
This is especially important when REGEN levels are being adjusted in real-time,
via MIDI control change messages, during a performance.
The regeneration levels can be reset by recalling the preset or by
accessing the REGEN 1 and REGEN 2 parameters and turning the ADJUST control.

REVERB Function
The REVERB function is available in all presets.
Reverb is a multitude of echos spaced so close together that, to the
human ears seem as a single continuous sound. These echos gradually decrease
in intensity until they are ultimately absorbed by the boundaries and obstacles
within a room. As the sound waves from the sound source strike the boundaries
of a room, a portion of the energy is reflected away from the obstacle
while another portion is absorbed into it – thereby causing both the continuance
of sound as well as the decaying or “dying out’ of the sound.
The PARAMETER SELECT control will allow you to access these REVERB
parameters:
REV INPUT
The REVERB INPUT parameter determines whether the input to the Reverb
section is ACTIVE (passing a signal) or MUTED (will not pass a signal).
MIX DIR/DLY
The MIX DIRECT/DELAY parameter is used to define the ratio of direct
signal to delayed signal to be input to the reverb section.
REVERB LVL
The REVERB LEVEL parameter allows you to control the level of the reverb
signal at the output in relation to the direct signal and other effect
signals. This parameter is also accessable from the Mixer function.
REV DECAY
The REVERB DECAY parameter determines the length of time that the reverb
signal will sound before it has completely died out.
REV HF DAMP
The REVERB HIGH FREQUENCY DAMPING parameter is used to control the
decay rate of high frequency information in the reverb signal. Higher parameter
settings will result in a faster decay of high frequency information.

Controller Assignments
The Controller Assignment function allows for specific Chameleon™ adjustable
parameters to be mapped (or assigned) to a MIDI controller for real-time
control by an expression pedal.
The Controller Assignment option also lets you store an upper and lower
parameter value limit which the controller cannot exceed. For example,
when using an expression pedal with a Rocktron All Access™ to send continuous
control changes to control the “PITCH” parameter, an upper limit
of +300 can be set and a lower limit of -200 can be set – even though the
actual parameter range is from +1200 to -2400. When the expression pedal
is at its heel position in this example, the “PITCH” parameter
will be at -200, while at its toe position it will be at +300.
Up to eight controllers can be assigned for each individual preset.

Step 1 To access the Controller Assign function, turn the FUNCTION
SELECT control clockwise to “CONTROLLER ASSIGN”.
Step 2 Turn the PARAMETER SELECT control for the first parameter
of the Controller Assign function. This parameter allows you to select
a controller number for the NUMB 1 parameter to respond to.

This parameter (NUMB 1 only) also gives you the option of selecting
“ADJ”. When “ADJ” is selected, the parameter assigned
to the first controller (PARA 1) can be instantly accessed by turning the
PARAMETER ADJUST control when the preset title is displayed. This allows
you to access a parameter that you adjust frequently without paging through
function headings and parameters.

Step 3 Use the PARAMETER ADJUST control to select the controller
number to be assigned to the PARA 1 parameter. Any number from 0 to 120
may be selected, as well as OFF (will not respond to MIDI control changes).
Match the number selected for this parameter with the controller number
on the MIDI transmitter.
Step 4 After selecting the desired controller number, press
the STORE button to save the number for the NUMB 1 parameter. “STORED”
will flash briefly on the display.
Step 5 Turn the PARAMETER SELECT control one step clockwise
to display the parameter that is currently mapped to the NUMB 1 control
number.
Step 6 Turn the PARAMETER ADJUST control to scroll through the
available parameters for the current configuration.
Step 7 After selecting the parameter that you which to assign
to a controller, press the STORE button to save it. The Chameleon™ will
flash “STORED” briefly.
NOTE: The Chameleon™ allows you to select an upper and lower
value limit which the parameter cannot exceed. For example, if a parameter
has a value range from -oo to 0dB, yet you would like the range of the
parameter to vary from only -12dB to -2dB, you may set a lower limit of
-12 and an upper limit of -2 via the Upper and Lower Limit parameters.
When a parameter is stored in the Controller Assign function (Step 7),
the maximum parameter value is automatically stored as the upper limit,
while the minimum value is stored as the lower limit.
Step 8 Turn the PARAMETER SELECT control one step clockwise
to display the Upper Limit parameter (for PARA 1).
Step 9 Use the PARAMETER ADJUST control to choose the highest
value that the parameter is not to exceed through MIDI control changes.
Step 10 After selecting a value for the upper limit, press the
STORE button to save it. “STORED” will flash briefly on the display.
Step 11 Turn the PARAMETER SELECT control one step clockwise
to access the Lower Limit parameter (for PARA 1).
Step 12 Use the PARAMETER ADJUST control to select the lowest
value which the parameter is not to fall below through MIDI control changes.
Step 13 After selecting a value for the lower limit, press the
STORE button to save it. “STORED” will flash briefly on the display.

Selecting a lower limit value that is greater than the upper limit
value will invert the response of the controller – i.e. the toe position
of the expression controller will provide the minimum value, while the
heel posilion will provide the maximum value.
NOTE: Steps 1-13 are repeated seven times for a total of eight
controllers. To exit Controller Assign at any time, turn either the PRESET
or FUNCTION SELECT control. Only changes that have been stored will be
saved after exiting the Controller Assign function.

Tap Delay
The Chameleon™ allows you to change the current delay time settings
for the Delay 1 and Delay 2 parameters while you are playing by connecting
a momentary footswitch to the rear panel FOOTSWITCH jack. When the Footswitch
function is activated, tapping the footswitch will change the current delay
time based on the amount of time that passes between taps. The Chameleon™
will detect the amount of time between any two taps that are less than
one second apart (i.e., if more than one second passes after the first
tap, two more taps – less than one second apart – will be required to change
the delay time again).
After the Chameleon™ detects the length of time between each tap, it then
multiplies or divides that time based on the type of note stored in each
of the DELAY 1 and DELAY 2 parameters of the Footswitch function. The resulting
delay time can be:

one-fourth of the time between taps (SIXTEEN)
one-half of the time between taps (EIGHTH)
two-thirds of the time between taps (TRIPLET)
equal to the time between taps (QUARTER)
two times the amount of time between taps (HALF), or
four times the amount of time between taps (WHOLE)

The maximum delay time the Chameleon™ provides is 1000ms, therefore
the Tap Delay feature will default to a lower parameter value when the
time between taps requires a delay time over 1000ms. For example, if the
WHOLE setting is stored for the Delay 1 parameter and the time between
taps is 300ms, a delay time of 1200ms would be required (i.e. 300ms x 4).
Because the maximum delay time is 1000ms, the Chameleon™ will default to
the next lower multiplier (HALF) and provide a delay time two- times the
delay time detected (600ms). if the delay time was over 1000ms again, the
unit would then provide the QUARTER note equivalent.
NONE can also be selected for the Delay 1 and Delay 2 parameters so that
they will not respond to taps on the footswitch.

Step 1 Turn the FUNCTION SELECT control to “FOOTSWITCH”.
Step 2 Turn the PARAMETER SELECT control one step clockwise
to display the current momentary footswitch “TYPE” (normally
open or normally closed).
The Footswitch TYPE parameter setting is global (i.e. the same for
all presets).
Step 3 Turn the PARAMETER ADJUST control to select the footswitch
type that you will be using (normally “OPEN” or “CLOSED”).
Step 4 Press the STORE button to save the altered Footswitch
Type setting. “STORED” will flash briefly on the display.
Step 5 Turn the PARAMETER SELECT control to one step further
clockwise to access the current status for “DELAY 1”.
Step 6 The PARAMETER ADJUST control can be used to change the
current DELAY 1 status.
Step 7 Press the STORE button to save the altered Delay 1 setting.
“STORED” will flash briefly on the display.
Step 8 Turn the PARAMETER SELECT control one step further clockwise
to access the current status for “DELAY 2”.
Step 9 Turn the PARAMETER ADJUST control to change the current
DELAY 2 status.
Step 10 Press the STORE button to save the altered Delay 2 setting.
“STORED” will flash briefly on the display.

The DELAY 1 and DELAY 2 parameters can be stored differently for
each preset.

Program Changes
Program Changes allow for different MIDI program numbers to be assigned
to Chameleon™ preset numbers. For example, MIDI program #58 can be mapped
to Chameleon™ preset #34. Then, when program #58 is selected from a MIDI
transmitting device (such as a Rocktron All Access™ foot controller), preset
#34 will be recalled on the Chameleon™.
The Program Changes Map table is shipped from Rocktron at a one-to-one
Correspondence (i.e. MIDI program #1 is mapped to Chameleon™ preset #1,
2 to 2, 3 to 3, etc.).

Step 1 To access MIDI Program Mapping, turn the FUNCTION SISLISCT
control clockwise until the Chameleon™ displays “PROGRAM CHANGES”.
Step 2 Turn the PARAMETER SELECT control one step clockwise
to display the current Program Change On/Map/Off status.

Program Changes status options

ON – Execute MlDI program changes as received by a MIDI controller
MAP – Use mapping table when a program change is received
OFF – Do not execute MlDI program changes

Step 3 Turn the PARAMETER ADJUST control to select the desired
Program Changes status setting.
Step 4 Press the STORE button to save the status selection.
“STORED” will flash briefly on the display.
Step 5 Turn the PARAMETER SELECT control one step clockwise
to display the current Program Changes mapping assignments.
Step 6 The number on the left of the display is the MIDI program
number (or the number sent via a MIDI footswitch or other MIDI transmitter).
Turn the PARAMETER SELECT control to select the MIDI program number to
map to a preset.
Step 7 The number on the right of the display is the preset
number to map to (or the preset number that will be recalled when the MIDI
program number on the left is received). Turn the PARAMETER adjust CONTROL
to select the preset number to map to.
* The preset number to map to can also be set to “OFF”
– thereby not responding to that program change command.
Step 8 After selecting both the MIDI program number and the
preset number, press the STORE button to save the change for each altered
mapping. “STORED” will flash briefly on the display.

MIDI Channels
The Chameleon™ can receive MIDI commands from other MIDI transmitting
devices, as well as transmit MIDI program changes to other MlDI-based equipment
when a preset is recalled on the Chameleon™ via the front panel RECALL
button. The MIDI Channels function allows you to select the MIDI channels
that the Chameleon™ will receive and transmit MIDI information on.

Step 1 Turn the FUNCTION SELECT control clockwise until the Chameleon™
displays “MIDI CHANNELS”.
Step 2 Turn the PARAMETER SELECT control one step clockwise
to display the current MIDI Receive channel.
Step 3 Turn the PARAMETER ADJUST control to select the desired
MIDI channel. You may select channels 1-16, OMNI (all channels) or OFF
(will not receive MIDI commands).
Step 4 Press the STORE button to save the new MIDI Receive channel.
“STORED” will flash briefly on the display.
Step 5 Turn the PARAMETER SELECT control one step further to
access the MIDI Transmit Channel status.
Step 6 Turn the PARAMETER ADJUST control to select the channel
that the Chameleon™ will transmit a MIDI program change on. you may select
channels 1-16 or OFF (will not transmit a MIDI program change).
Step 6 Press the STORE button to save the new MIDI Transmit
channel. “STORED” will flash briefly on the display.

MIDI Dump/Load
Any or all of the Chameleon™ presets may be dumped to a sequencer or
another Chameleon™ via system exclusive messages. The information exchanged
when performing a MIDI Dump consists of parameter values, title characters
and controller assignment/limit information. When dumping a single preset
into another Chameleon™, the dumped preset may be loaded into any preset
location on the receiving Chameleon™.
To dump a single Chameleon™ preset into another Chameleon™:

Step 1 Connect a standard MIDI cable from the MIDI OUT of the
transmitting Chameleon™ to the MIDI IN on the receiving Chameleon™.

IMPORTANT: Do not allow a looping connection from the MIDI OUT/THRU
of the receiving Chameleon™ back to the MIDI IN of the transmitting Chameleon™.
Click here to see a graphic of the MIDI
hook up.

Step 2 Turn the FUNCTION SELECT controls on both the transmitting
and receiving Chameleons until “MIDI DUMP/LOAD” is displayed
on each.
Step 3 Turn the PARAMETER SELECT control on each unit one step
clockwise to “PR DUMP/ LOAD”.
Step 4 Turn the PRESET control on the transmitting Chameleon™
to the preset that is to be dumped into the receiving Chameleon™. As the
PRESET control is turned, the preset number will be displayed in the first
three characters of the display.
Step 5 Use the PRESET control on the receiving Chameleon™ to
select the preset location to store the received preset. The preset currently
stored at the selected location will be lost when the new preset is received,
therefore caution should be used when selecting a preset location.
Step 6 To initiate the dump, press the STORE button on the transmitting
Chameleon™. The transmitting Chameleon™ will display the preset number
being dumped and “DUMPED”. The receiving Chameleon™ will display
the preset location being stored to and “RECEIVING…” while
it receives and stores the preset parameters and title.
After all the information for the dumped preset is stored, the receiving
Chameleon™ will display “LOADED”. The receiving Chameleon™ also
recalls the loaded preset at this time so that it may be verified.
Note: If there is an error in transmission, the unit will
display “RECEIVE ERROR “. Should this occur, check connections
and try again. If other errors occur, check the Error Messages chart in
the Appendix.

To dump the Chameleon™ memory into a sequencer:

Step 1 Connect a standard MIDI cable from the MIDI OUT of the
transmitting Chameleon™ to the MIDI IN on the receiving sequencer.

Click here to see a graphic of the
MIDI hook up.

Step 2 Turn the FUNCTION SELECT controls on the transmitting
Chameleon™ until “MIDI DUMP/LOAD” is displayed.
Step 3 Turn the PARAMETER SELECT control on the transmitting
Chameleon™ until “BULK DUMP/LOAD” is displayed.
Step 4 Start the sequencer recording.
Step 5 Press the STORE button on the Chameleon™ to initiate
the data dump. As the Chameleon™ performs the dump, it will display “XXX
DUMPED” – where “XXX” = the number of the data string currently
transmitting (i.e. strings 1-254 are presets, titles, controller information
and 2-tap delay information; string 255 contains program mapping information;
and string 256 contains miscellaneous information.
Step 6 After the Chameleon™ displays “TRANS COMPLETE”,
stop the sequencer. The sequencer should have recorded all of the data
that was dumped from the Chameleon™. Keep this data stored on a disk in
a safe place. Turn the PARAMETER SELECT control to continue.

To reload user data from a sequencer:

Step 1 Connect a standard MIDI cable from the MIDI OUT of the
transmitting sequencer to the MIDI IN on the receiving Chameleon™.

IMPORTANT: Do not allow a looping connection from the MIDI OUT/THRU
of the receiving Chameleon™ back to the MIDI IN of the transmitting sequencer.
Click here to see a graphic of the MIDI
hook up.

Step 2 Turn the FUNCTION SELECT controls on both the receiving
Chameleon™ until “MIDI DUMP/LOAD” is displayed.
Step 3 Turn the PARAMETER SELECT controls on the receiving Chameleon™
until “BULK DUMP/LOAD” is displayed.
Step 4 Play back the data stored on the sequencer. The Chameleon™
will display the data strings as it is storing them. Each data string will
appear with the word “LOADED”. After all the user data has been
loaded, the Chameleon™ will display “LOAD COMPLETE”. Do not play
back the data from the sequencer faster than it was loaded, as errors may
occur (errors may also occur if any knob is turned or any button is pressed
before the message “LOAD COMPLETE” appears).
If errors occur during transmission, the unit will display “RECEIVE
ERROR ” for transmission errors and “XMEM ERROR” for internal
hardware errors. Errors occurring in transmission does not indicate that
all of the received data is corrupted. Only the transmission string where
the error occurred is corrupted.
When receiving a Bulk Load, it is important that the data loaded
to the Chameleon™ is not transmitted faster than it was originally dumped
from the Chameleon™ If information is sent too fast to the Chameleon™,
an error will occur.
When dumping information from a data storage device, such as an
Alesis Data Disk, it is necessary to perform the dump in sequence mode
rather than sysx mode. Sequence mode will dump the information back to
the Chameleon™ at the same rate as it was received from the Chameleon™.
The Chameleon™ can receive a data dump at about 65Hz (or about 1 byte every
15 milliseconds).

Factory Restore
The Factory Restore function allows you to restore altered Chameleon™
presets to their original condition as shipped from the factory. Either
the entire Chameleon™ memory can be restored, a single preset can be restored
to any preset location, or the controller information alone can be restored.
Restoring a single factory preset:

Step 1 Turn the FUNCTION SELECT control clockwise to “FACTORY
RESTORE”.
Step 2 Turn the PARAMETER SELECT control one step clockwise
to “RESTR 1 TO 1”. The number on the left is the original factory
preset number to be restored. The number on the right is the preset location
that the preset will be stored into.
Step 3 Turn the PRESET control to select the factory preset
to be restored.
Step 4 Turn the PARAMETER ADJUST control to select the preset
location to store the restored preset into.

!! CAUTION !!
Pressing the STORE button at this time will overwrite
the current preset with the displayed factory preset.

Step 5 Press the STORE button to begin restoring the selected
preset into the selected location. After the process is completed, the
display should read “ERRORS 0”. This represents the number of
bytes that the Chameleon™ found did not initialize properly. Any number
of errors other than “0” means that the Chameleon™ may not have
initialized properly and the process should be repeated.
The Chameleon™ will remain in this condition until the FUNCTION
SELECTcontrol is turned to exit the Factory Restore function. The preset
currently recalled will be the preset most recently restored into the current
location.

Restoring all factory presets:

!! CAUTION !!
This procedure will permanently erase all user presets (1-254) and replace
them with the original factory presets. If you have altered and stored
presets
which you do not want to erase, do not perform the following procedure.

Step 1 Turn the FUNCTION SELECT control clockwise to “FACTORY
RESTORE”.
Step 2 Turn the PARAMETER SELECT control two steps clockwise
to “ALL RESTORE 0”.
Step 3 A specific code number must be entered to restore the
Chameleon™ memory. Use the PARAMETER ADJUST control to enter the number
“243”.

! ! WARNING ! !
Pressing the STORE button at this time will permanently erase all
user presets and replace them with the original factory presets. If
you have altered and stored presets which you do not want to erase,
turn the FUNCTION SELECT control to exit this function.

Step 4 Press the STORE button at this time to initiate the All
Restore procedure and erase all current Chameleon™ presets, replacing them
with the original factory presets. The Chameleon™ will display “INITIALIZING”
as the Chameleon™ memory is restored.
Afler the All Restore process is completed, the display should read
“ERRORS 0”. This is the number of bytes that the Chameleon™ found
that did not initialize properly. Any number of errors other than “0”
means that the Chameleon™ may not have initialized properly and the process
should be repeated.
The Chameleon™ will remain in this condition until the FUNCTION
SELECCT control is turned to exit the Factory Restore function. The preset
currently recalled will be the preset most recently restored into the current
location.

Restoring the Chameleon™ controller assignments:

The controller assignments for the Chameleon™ can also be reinitialized
without affecting presets and other stored information. Reinitialization
of the controller assignments is necessary when setting up the Chameleon™
to operate in remote mode with a Rocktron All Access™ footswitch.
To reinitialize only the controller assignments, enter a code number
of “244” at Step 3 above.

Back to CONTENTS

Selecting a Power
on Preset:
The Chameleon™ allows you to store a Power On preset which will always
be recalled when the unit is turned on.

Step 1 Turn the PRESET control to the preset number you wish
to be recalled each time the unit is turned on.
Step 2 Recall the selected preset by pressing the RECALL button.
Step 3 Press the STORE button while viewing the preset number
and title to save it as the Power On preset.

Using the Chameleon™
with a Rocktron All Access™ in REMOTE mode
A Rocktron All Access™ MIDI footswitch can act as a dedicated remote
control for the Chameleon™ – allowing direct access to specific Chameleon™
features and parameters from the footswitch at any time.

Step 1 To use an All Access™ footswitch as a dedicated remote,
connect the MIDI OUT of the All Access™ to the REMOTE jack of the Chameleon™
using a 7-pin MIDI cable.

Click here to see a graphic of
the MIDI hook up.
To set up the Chameleon™ for remote operations do the following:

Step 2 Reinitialize the controller assignments as shown earlier
in this section under the heading “Restoring the Chameleon™ Controller
Assignments”. This will match up the Chameleon’s controller assignments
to the All Access™. A code of “244” must be entered to initialize
only the controller information.
Step 3 Turn the FUNCTION SELECT control clockwise to “REMOTE
CONTROL”.
Step 4 Turn the PARAMETER SELECT control one step clockwise
to display “REMOTE”.
Step 5 Turn the PARAMETER ADJUST control to select “ON”.
Step 6 If the Chameleon™ titles are to be displayed on the All
Access™, turn the PARAMETER SELECT control to “TITLE XFER”.
Step 7 Turn the PARAMETER ADJUST control to “ON” to
enable title transfers from the Chameleon™ to the All Access™ display.

To set up the All Access™ for remote operation perform these steps
from the All Access™ SETUP program:

(See the All Access™ user’s manual for detailed information on editing
the All Access™)

Step 8 Set the Operating Mode to “REMOTE”.
Step 9 Set the Bank Size to “10”.
Step 10 Reinitialize only the controller information for the
instant access switches and pedals using a code of “231”.
Step 11 If the preset titles from the Chameleon™ are to be displayed
on the All Access™ automatically, set the Remote Title Number to match
the Unit ID Number parameter on the Chameleon™.

When operating in Remote mode with a Chameleon™, switches 1-10 act as
normal preset switches, while switches 11-15 each perform a special function.

Switch 11 switches in or out the first effect of the current
configuration (not including HUSH®). This can be either chorus, flange,
tremolo, pitch shift, wah or phase shift.
Switch 12 switches in or out the delay effect.
Switch 13 switches in or out the reverb effect.
Switch 14 can be pressed and held to mute the output of the
Chameleon™ for as long as the switch is held down. This is especially useful
when switching guitars during a live set.
Switch 15 provides instant access to the Tap Delay feature
of the Chameleon™ Switch 15 can be used instead of connecting a momentary
footswitch to the FOOTSWlTCH jack on the rear of the Chameleon™. For more
information on the Tap Delay Feature, see Tap Delay in this section.

Click here to see a graphic of
the All Access™ switch set up.
Upon proper setup and connection of the units, the All Access™ will
provide the functions shown in the graphic.
