schedkwhen

		  schedkwhen ktrigger, kmintim, kmaxnum, kinsnum, kwhen, kdur[, kp4, kp5, ...]

Description

Adds a new score event generated by a k-rate trigger.

Performance

ktrigger – triggers a new score event. If ktrigger = 0, no new event is triggered.

kmintim – minimum time between generated events, in seconds. If kmintim <= 0, no time limit exists. If the kinsnum is negative (to turn off an instrument), this test is bypassed.

kmaxnum – maximum number of simultaneous instances of instrument kinsnum allowed. If the number of extant instances of kinsnum is >= kmaxnum, no new event is generated. If kmaxnum is <= 0, it is not used to limit event generation. If the kinsnum is negative (to turn off an instrument), this test is bypassed.

kinsnum – instrument number. Equivalent to p1 in a score i statement.

kwhen – start time of the new event. Equivalent to p2 in a score i statement. Measured from the time of the triggering event. kwhen must be >= 0. If kwhen > 0, the instrument will not be initialized until the actual time when it should start performing.

kdur – duration of event. Equivalent to p3 in a score i statement. If kdur = 0, the instrument will only do an initialization pass, with no performance. If kdur is negative, a held note is initiated. (See ihold and i statement.)

kp4, kp5, etc. – Equivalent to p4, p5, etc., in a score i statement.

Note: While waiting for events to be triggered by schedkwhen, the performance must be kept going, or Csound may quit if no score events are expected. To guarantee continued performance, an f0 statement may be used in the score.
