Dual Channel MIDI Foot Switch
MIDI Implementation
According to the V-Amp Pro and Bass V-Amp Pro manuals, MIDI program change commands are used to change presets. Program values 0 to 124 select presets A01 through E25. Program change value 127 selects tuner mode.
The Dual Channel MIDI Foot Switch will default to MIDI channel 1 for channel 1 and MIDI channel 2 for channel 2. These can be modified to any of the available 16 channels using the Channel Select Mode.
The foot switch will have a single 5 pin, female DIN jack on the rear of the unit serving as a MIDI Out jack.
