10.2 MIDI

This chapter provides information (all implemented MIDI transmission commands) for the experienced software programmer that wants to design new software for the DSP 244. The implementation chart is relevant for the software revision V1.0 or higher.

MIDI data transfer is possible, only when a MIDI channel is activated (OMNI, 1 - 16). See also chapter 9.7, MIDI RX / TX CHANNEL settings.
