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.
