midiout

midiout — Sends a generic MIDI message to the MIDI OUT port.

Description

Sends a generic MIDI message to the MIDI OUT port.

Syntax

midiout kstatus, kchan, kdata1, kdata2

Performance

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] Warning

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.
