Linen

object Linen extends Serializable

A linear ASR-type envelope generator UGen.

Examples
// repeated trigger
play {
  val gen = Linen.kr(Impulse.kr(2), 0.01, 0.6, 1.0)
  SinOsc.ar(440) * gen * 0.1
}
// play once and end the synth
play {
  val gen = Linen.kr(Impulse.kr(0), 0.01, 0.6, 1.0, doneAction = freeSelf)
  SinOsc.ar(440) * gen * 0.1
}
// play once and sustain
val x = play {
  val gen = Linen.kr("gate".kr(1), 0.01, 0.6, 1.0, doneAction = freeSelf)
  SinOsc.ar(440) * gen * 0.1
}

x.release(4)    // release envelope with given duration
// longer gate to sustain for a given duration
play {
  val gate = Trig.kr(1, dur = 2)
  val gen = Linen.kr(gate, 0.01, 0.6, 1.0, doneAction = freeSelf)
  SinOsc.ar(440) * gen * 0.1
}

  14. def kr(gate: GE = 1, attack: GE = 0.01f, sustain: GE = 1.0f, release: GE = 1.0f, doneAction: GE = doNothing): Linen

    gate

    triggers the envelope and holds it open while greater than zero. A value of less than zero enforces a release with duration -1.0 - gate .

    attack

    duration (seconds) of the attack segment

    sustain

    level of the sustain segment

    release

    duration (seconds) of the release segment

    doneAction

    action to be performed when the envelope reaches its end point.
