A UGen that writes to buses that are local to the enclosing synth. These buses should have been defined by a LocalIn ugen. These behave like regular buses, but are more convenient for the implementation of a self contained effect that uses a feedback processing loop.

In a synth, there can be only each one control-rate and audio-rate LocalIn / LocalOut pair. The signal written to a LocalOut will not be read by the LocalIn until the next control block cycle, introducing a delay of ControlDur .

For more examples, see LocalIn.

Examples

// ping-pong delay with feedback
play {
  val src = Decay.ar(Impulse.ar(0.3), 0.1) * WhiteNoise.ar(0.2)
  val in  = LocalIn.ar(Seq(0, 0)) + Seq[GE](src, 0) // read feedback, add source to left chan
  val dly = DelayN.ar(in, 0.2, 0.2)         // delay sound
  val att = dly * 0.8                       // apply decay factor

  // reverse channels to give ping pong effect
  LocalOut.ar(Seq(att.out(1), dly.out(0)))
  dly
}
