## 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: 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.

## Examples

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