midiout_i

Sends a generic MIDI message to the MIDI OUT port.

Syntax

midiout_i istatus, ichan, idata1, idata2

Initialisation

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.

Examples

Here is an example of the midiout_i opcode. It uses the file midiout_i.csd.
