TExpRand

object TExpRand extends Serializable

A UGen that generates a new random decimal value each time it is triggered, using an exponential distribution from lo to hi . Values lo and hi must both have the same sign and be non-zero.

Note: Audio-rate inputs for lo and hi are currently broken in SuperCollider, and will therefore be converted to control-rate inputs.

Examples
// random sine frequencies, triggered by mouse button
play {
  val tr = MouseButton.kr(lag = 0)
  val m  = Mix.fill(10)(SinOsc.ar(TExpRand.kr(200.0, 800.0, tr)))
  m * Linen.kr(tr, sustain = 0.025, release = 2)
}
