MIDI Control
The M13 will send and receive MIDI CC and Program Change messages on any MIDI
Channel from 1 thru 16 or Omni, selectable from the M13 Setup mode, LCD 4. MIDI
implementation includes MIDI CCs for Looper Control, FX Unit On and Bypass messages,
Tap Tempo, Expression Pedal CCs and Program Change messages for Scene select. It is
therefor possible to control the M13 from a MIDI controller or a computer sequencer.
The most common application would probably be to use a separate MIDI controller to
control the M13 Looper, so that all 12 Scene select switches on the M13 would be available
for individual FX control.
Individual Model selection and assignment for each FX Unit from the 5 different FX groups
is not implemented, but individual FX loaded into the A, B and C memory locations of
all 4 FX Units can be engaged or bypassed via MIDI CCs. The MIDI Reference Tables
in this chapter represent the currenly implemented MIDI spec. A more expanded MIDI
implementation may be forthcoming in future M13 firmware updates.
