Changing MIDI Channel
Preamp MKII™ is set to MIDI channel 2 by default. This can be changed by holding down both stomp switches simultaneously when you provide power to the pedal and releasing the stomp switches once the seven segment display on the front of the pedal lights up. The pedal is now looking for the first Program Change message it sees and will set itself to whichever channel it receives that message from. This is saved as the new MIDI channel until you decide to change it again.Saving a preset via MIDI
You can save your current settings via MIDI to any of the 30 preset slots. Send CC#27 and the value (0-29) will save the current configuration to the intended preset slot. Remember, you can also save a preset to the current slot at any time by pressing and holding the SAVE stomp switch on the pedal.Recalling a preset via MIDI
Presets 0-29 are recalled using Program Changes 0-29. You can do this by sending the corresponding Program Change # from your MIDI controller. For example, sending a Program Change message of “4” loads bank one (left LED off), preset four. Sending a message of “17” loads bank two (left LED red), preset seven. Sending a program change of “20” loads bank three (left LED green), preset zero.Control Change Messages
