8 MIDI
As you've learned in chapter 2.2, presets can only be changed via MIDI.
Sender (controller) receiver (amp) must use the same channel. The factory
default is MIDI channel 1 and "Omni On". If the amp does not react on
program changes properly, the MIDI channel has to be changed.
8.1 Setting MIDI channels and switching
Omni On/Off
Flip the Play/Standby switch to Standby. Now press and hold Noise Gate
and FX-Loop simultaneously for three seconds. They will start flashing. This
assigns special programming functions to the following LEDs and buttons:
• FX-Access: lights up to indicate GrandMeister 36 is configured to receive
incoming program changes via all MIDI channels (Omni On, default). If
the LED is not illuminated, the amp receives messages via the selected
channel only (Omni Off). To change the Omni mode, just press the FX
Access button.
• Noise Gate now serves as a +1/up button, FX Loop now serves as a -1/
down button. Use those buttons to change the MIDI channel.
• When configuring MIDI channels, the four Channel LEDs serve to
indicate the MIDI channels. Consult the table below for the MIDI channel
assignments. They show what in tech-speak is called binary code:

Press and hold the two buttons "Noise Gate" and "FX Loop" simultaneously
for more than three seconds to save the settings and quit MIDI setup
mode. The buttons will stop flashing to indicate the amp is back in normal
operating mode.
