midiout — Sends a generic MIDI message to the MIDI OUT port.
kstatus -- 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
kchan -- MIDI channel (1-16)
kdata1, kdata2 -- message-dependent data values
midiout has no output arguments, because it sends a message to the MIDI OUT port implicitly. It works at k-rate. It sends a MIDI message only when kstatus is non-zero.

Warning: Normally kstatus should be set to 0. Only when the user intends to send a MIDI message, can it be set to the corresponding message type number. |
Here is an example of the midiout opcode. It uses the file midiout.csd.
