REMOTE

 

(MIDI LEARN)

 – Activates either of 2 rear panel isolated switching jacks for remote 

switching of amps, preamps or accessories and assigns operation of the switch function to any 
selected channel. The REMOTE jacks on the rear panel are labeled REMOTE 1, which is only 
activated when the CLEAN channel is engaged, and REMOTE 2, which is activated whenever 
the RHYTHM, or LEAD channel is engaged. When REMOTE 1 is activated, the CLEAN 
channel LED will flash. When REMOTE 2 is activated, the RHYTHM or LEAD channel LED or 
both will flash depending on which of these channels’ REMOTE function has been selected. 

(Activates MIDI LEARN function).

 – Selects CLEAN, RHYTHM or LEAD channel. 

(Simultaneously mutes 

all three channels when held down for 2 seconds).  
 
(WARM-UP SEQUENCE OVERRIDE) – 

This function is accessed right after power up. In the 

event that the GP3 has already been operating and power is temporarily interrupted, it is not 
necessary to wait  for the complete warm-up sequence to resume operation. You can manually 
override the WARM-UP SEQUENCE by tapping the CHANNEL button once during warm-up. 
This will reduce the WARM-UP SEQUENCE interval from 15 seconds to 3 seconds. 

 
(MEMORY CLEAR) – 

This function is accessed on power up. To clear ALL memory contents, 

hold down BRITE and REMOTE functions and engage the power switch. 

 
MIDI/MIDI LEARN 

Setting up MIDI patches is a snap with the GP3. There are 4 banks of MIDI presets available, 
FACTORY, USER 1, USER 2 AND USER 3, (refer to the GLOBAL FUNCTIONS section 
above) which are selected as follows: Press the REMOTE key for 2 seconds. The CHANNEL 
LEDs will turn off and one of the 4 MIDI Preset Bank LED indicators will flash. Your GP3 
comes from the factory preset to the Factory ROM bank. There are 127 combinations of channels 
and global functions recorded here, configured as Programs 0-126. See MIDI PROGRAM 
CHART in Appendix I for details. To access the Factory Program Bank, first confirm that the rear 
panel SELECT/OMNI switch is set to OMNI. Connect the MIDI OUT from your MIDI controller 
to the MIDI IN on the back of the GP3. Next, power up the GP3 and your controller, then select a 
MIDI program number on your MIDI Controller

.  

 
NOTE: All four PROGRAM BANKS include a factory MUTE setting on MIDI program 0. 
Program 0 is NOT a user programmable/erasable location.
