midiout_i — Sends a generic MIDI message to the MIDI OUT port.
istatus -- the type of MIDI message. Can be:
128 (note off)
144 (note on)
160 (polyphonic aftertouch)
176 (control change)
192 (program change)
208 (channel aftertouch)
224 (pitch bend)
0 when no MIDI messages must be sent to the MIDI OUT port
ichan -- MIDI channel (1-16)
idata1, idata2 -- message-dependent data values
midiout_i has no output arguments, because it sends a message to the MIDI OUT port implicitly. It works at i-time. It sends a MIDI message only when istatus is non-zero.
Here is an example of the midiout_i opcode. It uses the file midiout_i.csd.
