Roland GP-100 TURBO FACTS

The Roland GP-100 Guitar Preamp/Processor is the first rack mount effects processor
to use Composite Object Sound Modeling (COSM). This new technology allows the GP-100
to accurately reproduce classic guitar amps, a large selection of speaker cabinets and
several different microphones. Dedicated knobs are provided to allow you to easily
change the preamp settings of the GP-100. The GP-100 can produce up to 16 effects
simultaneously which can be arranged in any order. These include a wide variety of
effects like ducking delay, tap delay, noise suppressor, phaser, reverb, slow gear,
tremolo/pan, chorus, compressor /limiter, equalizer and intelligent pitch shifting.
The 200 Preset and 200 User Patches include 16 realtime controllers, selectable stereo outputs,
two programmable effects loops and two external control switches. The system can be
set up with a guitar amp or direct to the board for recording. The GP-100 also includes
a built in chromatic guitar tuner.

Initializing the GP-100

1. Hold the PARAMETER knob while powering on.
2. Press WRITE.

Connecting the GP-100 to a Sound System
Both pair of stereo outputs can be individually setup to work with a standard guitar amp or direct into a full range PA or recording system. The factory presets are setup to use the OUTPUT A L(MONO) and R connections. Connect a set of cables from these outputs.

1. Press GLOBAL.
2. Rotate PARAMETER to Amp Being Used:A.
3. Rotate VALUE to select Solid State or Tube to determine the amplifier you are using.
4. Dial PARAMETER to SP(eakers) Being Used:A. VALUE to the appropriate cabinet type - Built In for combo amps or stack for separated.
5. Dial PARAMETER to SP(eaker) Color:A. Dial VALUE to Adjust for guitar amp.
6. Press EXIT to return to play mode.

Tuning the Guitar

1. Connect a guitar to the INPUT on the front panel.
2. Press the TUNER button and play each string.
3. Adjust the tuning of each string to the center position of the meter.
4. Press EXIT to return to play mode.

Auditioning Patches
The GP-100 has 200 user programmable (001 to 200) and 200 preset patches (201 to 400). To scroll through patches one at a time, rotate the NUMBER knob. Pressing the NUMBER knob in while rotating it will change patches in increments of 10. Check out the following patches:

1. 001 CLASSIC STACK - 1959 Marshal stack with realistic dynamic control.
2. 002 JC-120 Clean - Original sound of the Roland JC-120 Jazz Chorus amplifier.
3. 007 5VOICE HARMONY - Thick harmony in the key of C.
4. 011 BOOGIE LEAD - Mesa Boogie Lead channel with stack.
5. 012 VINTAGE TWIN - Classic Fender Twin with 2 x 12² speakers.

Editing Sounds
The PREAMP knobs are similar to knobs on a standard guitar amplifier. Rotate the knob past the original value so that it catches the number, then continue to rotate to change the value of the selected parameter.

1. Select any patch as a starting point.
2. Rotate the PARAMETER knob. The effects will be abbreviated with two letters.
3. Press the VALUE knob to turn effects ON or OFF. Rotate VALUE to change the placement of the selected effect in the chain. (The DUAL algorithm can not reorder the effects).
4. Continue rotating PARAMETER to access the parameters of each effect. Press and rotate PARAMETER to skip through each effect quickly.
5. Rotate VALUE to change effects settings. Press and rotate VALUE knob to change values quickly.

Writing a Patch
Once you have edited a sound you can write it to any of the 200 user programmable memory locations.

1. Press WRITE. The number of the PATCH will flash.
2. Use the VALUE dial to select the location in which you want to store your Patch.
3. Press WRITE again.

Realtime Control
With an FC-200 MIDI Foot Controller, expression pedal, or foot switch, it is possible to control up to 16 parameters of the GP-100 in realtime - 8 continuous and 8 effects on/off. Connect the FC-200 to the MIDI IN and an expression pedal to the EXP Pedal jack on the back. The CONTROL 1/2 jack can be used with a PCS-31 insert cable and two FS-5U foot pedals to turn effects on and off without changing a patch. To program the GP-100 to respond to the expression and control pedal on the FC-200:

1. Rotate PARAMETER until the screen reads [Assign 2 Target]. Rotate VALUE to select parameters. (Assign 1 can only be used for volume or wah. Assign 2 through 8 can target any parameter).
2. Rotate PARAMETER to [Assign 2 Min] and use VALUE to set the range. Repeat for [Assign 2 Max].
3. Rotate PARAMETER to [Assign 2 Source] and VALUE to [MIDI CTL #7] for FC pedal, [MIDI CTL #80] for FC switch, [EXP PEDAL] or [CONTROL 1/2] for pedals.
4. Experiment with the pedal to see how it controls the sound parameters in realtime.

Understanding Algorithms
The top row of the display screen shows the Patch number and Algorithm name. Algorithms are a collection of effects with the parameters available for each effect.

The GP-100 has five algorithms: BASIC, DELAY, HARMONY, VINTAGE and DUAL.

BASIC: A set of effects that are quick and easy to program, including Compressor, Wah, EQ, Noise Suppressor, Harmonist, Delay, Chorus and Reverb.

DELAY: All the effects available in BASIC plus Phase, Flange and a more powerful 4 tap ducking delay.

HARMONY: The BASIC effects with an impressive intelligent pitch-shifter.

VINTAGE: The BASIC effects along with some unique BOSS pedals including Tremolo/Pan, Vibrato, Auto Wah, Slow Gear and Feedbacker.

DUAL: Two chains of effects which include the Preamp along with EQ, Delay, Chorus and Reverb. These chains can be layered, switched or morphed in realtime with a foot pedal or other controller.
