3.1 3.1 3.1 3.1 CHANNEL COMMANDS CHANNEL COMMANDS CHANNEL COMMANDS CHANNEL COMMANDS
The interface receives MIDI commands on selected MIDI channel ("MIDI Channel" parameter – see chapter 2.1).
In OMNI mode, interface receives data on all 16 MIDI channels simultaneously.
3.1.1 3.1.1 3.1.1 3.1.1 NOTE ON/OFF NOTE ON/OFF NOTE ON/OFF NOTE ON/OFF
The interface recognizes MIDI Note On/Off commands with note numbers in range of 5 octaves. “Key Shift“
parameter (see chapter 2.2) defines assignment of MIDI notes to instrument’s keys. When six valid MIDI notes
are received (all six instrument’s voices are sounding), all following received MIDI Note commands are
processed according to “Key Priority“ parameter setting (see chapter 2.3).
