A separate MIDI channel can be assigned for receiving effect modulation/controller messages
A separate channel can be assigned to receive Config Preset program changes
Separate program change map tables per Unit and Config
Responds to the following MIDI controllers (for effect parameter modulation or Bypass/Kill status changes):
Controllers #000 - #127
Pitch bend wheel
Note number
Velocity
Pressure (channel/mono or key/polyphonic)
Local Controllers (an also send MIDI events):
Control voltage input
Up to 4 Foot switches (2 x SW-10)
Can save/load the following data types via MIDI System Exclusive
Single Presets
Bank of related Presets (1 Unit, 2 Unit, or Config)
System global data
