midion2

midion2 — Sends noteon and noteoff messages to the MIDI OUT port.

Description

Sends noteon and noteoff messages to the MIDI OUT port when triggered by a value different than zero.

Syntax

midion2 kchn, knum, kvel, ktrig

Performance

kchn -- MIDI channel (1-16)

knum -- MIDI note number (0-127)

kvel -- note velocity (0-127)

ktrig -- trigger input signal (normally 0)

Similar to midion, this opcode sends noteon and noteoff messages to the MIDI out port, but only when ktrig is non-zero. This opcode is can work together with the output of the trigger opcode.

Examples

Here is an example of the midion2 opcode. It uses the file midion2.csd.
