object Dshuf extends Serializable

A demand-rate UGen which outputs a randomly shuffled version of an input sequence. The sequence is only shuffled once, thus when repeats is greater than one, the same randomized sequence will be repeated, until the UGen is reset. This happens for example, when it is nested inside a Dseq , as shown in the example "reshuffle".

Examples
// sequence of constants
play {
  val in = Dshuf(Seq(3, 5, 7, 8, 11), inf)
  val tr = Impulse.kr(5)
  val v  = Demand.kr(tr, in)
  v.poll(tr)
  val f  = (v + 62).midicps
  SinOsc.ar(f) * 0.1
}
// reshuffle
play {
  val in = Dseq(Seq[GE](Dshuf(Seq(3, 5, 7, 8, 11), 4), 24), inf)
  val tr = Impulse.kr(5)
  val v  = Demand.kr(tr, in)
  v.poll(tr)
  val f  = (v + 62).midicps
  SinOsc.ar(f) * 0.1
}
// audio rate
play {
  val in = Dseq(Seq(Dshuf(Seq.fill(81)(util.Random.nextInt(10)), 5)), inf)
  val tr = Impulse.ar(500)
  val f  = Demand.ar(tr, in) * 30 + 340
  SinOsc.ar(f) * 0.1
}
// embedded structures
play {
  val in = Dseq(repeats = inf, seq =
    Dshuf(repeats = 8, seq = Seq[GE](
      Drand(Seq(1, 2, 3), 1),
      3,
      Drand(Seq(20, 23, 56), 1),
      7, 8.5)))
  val tr = Impulse.kr(MouseX.kr(1, 40, 1))
  val f  = Demand.kr(tr, in) * 30 + 340
  SinOsc.ar(f) * 0.1
}
