ListTrig

A UGen that produces a scheduled sequences of trigger impulses. Trigger times are provided as a list (buffer) of absolute offsets from time zero. A trigger is output as a single control period of value 1 , after which output returns to zero.

Examples

// trigger grains
val b = Buffer(s)
b.alloc(10)
b.setData(Vector(1, 2, 3, 5, 8, 13, 21, 34, 55, 89).map(_ * 0.1f)) // quasi Fibonacci

val x = play {
  val reset = "reset".tr
  val tr  = ListTrig.kr(b.id, BufFrames.kr(b.id), reset)
  Timer.kr(tr).poll(tr, "timer")
  val env = EnvGen.ar(Env.perc(0.01, 0.1), gate = tr)
  SinOsc.ar(Seq(440, 460)) * env * 0.2
}

x.set("reset" -> 1)  // start anew
x.free(); b.free()

Note: The argument order is different from its sclang counterpart.

def kr(buf: GE, size: GE, reset: GE = 0, delay: GE = 0): ListTrig

buf
identifier of the buffer containing the offsets for the triggers in seconds. The offsets are taken against the start time of the synth or the last time a reset was received. They are not accumulative, and the behavior is undefined if the values are not sorted in ascending order. The buffer should be monophonic.
size
the number of values to use from the buffer. Typically, this should be BufFrames.kr(buf) .
reset
resets the timer and begins reading the time offsets again at the start of the buffer.
delay
this value is added to each of the buffer values. For example, to delay the list of values all by half a second, use a delay of 0.5 . This parameter is only updated at initialization or reset.
