schedule — Adds a new score event.
schedule insnum, iwhen, idur [, ip4] [, ip5] [...]
schedule "insname", iwhen, idur [, ip4] [, ip5] [...]
insnum -- instrument number. Equivalent to p1 in a score i statement. insnum must be a number greater than the number of the calling instrument.
“insname” -- A string (in double-quotes) representing a named instrument.
iwhen -- start time of the new event. Equivalent to p2 in a score i statement. iwhen must be nonnegative. If iwhen is zero, insum must be greater than or equal to the p1 of the current instrument.
idur -- duration of event. Equivalent to p3 in a score i statement.
ip4, ip5, ... -- Equivalent to p4, p5, etc., in a score i statement.
ktrigger -- trigger value for new event
schedule adds a new score event. The arguments, including options, are the same as in a score. The iwhen time (p2) is measured from the time of this event.
If the duration is zero or negative the new event is of MIDI type, and inherits the release sub-event from the scheduling instruction.
Here is an example of the schedule opcode. It uses the file schedule.csd.
