midifileloop

Sets the looping mode of a MIDI file playback.

This opcode can be called from anywhere, it is also a non-op if used in an instrument triggered by a MIDI event.

Requires the -F flag to operate. If a filename is passed to -F, it is open with id 0 and playback starts immediately.

Syntax

 midifileplay(loop:i, [id:i])
 midifileplay(loop:k, [id:i])

midifileplay iloop, [id]
midifileplay kloop, [id]

Initialization

id (optional, default=0) -- MIDI file id, defaults to 0, the id of any file passed to the -F flag.

loop -- playback loop mode: 1 = on, 0 = off

Performance

loop -- playback loop mode: 1 = on, 0 = off

Examples

Here is an example of the miditempo opcode. It uses the files midifileloop.csd.
