Instrument reference. we can invoke or stop the instrument by the identifier.

Creates a new instrument and generates a unique identifier.

Schedules an event for the instrument.

scheduleEvent instrRef delay duration args

The arguments for time values are set in seconds.

Turns off the note played on the given instrument. Use fractional instrument reference to turn off specific instance.

turnoff2 instrRef mode releaseTime

The mode is sum of the following values:

• 0, 1, or 2: turn off all instances (0), oldest only (1), or newest only (2)
• 4: only turn off notes with exactly matching (fractional) instrument number, rather than ignoring fractional part
• 8: only turn off notes with indefinite duration (idur < 0 or MIDI)

releaseTime if non-zero, the turned off instances are allowed to release, otherwise are deactivated immediately (possibly resulting in clicks).

Negates the instrument identifier. This trick is used in Csound to update the instrument arguments while instrument is working.

Adds fractional part to the instrument reference. This trick is used in Csound to identify the notes (or specific instrument invokation).

Creates an insturment that produces a value.

Triggers a note with fractional instrument reference. We can later stop the instrument on specific note with function noteOff.

Stops a note with fractional instrument reference.
