A graph element which writes to a connected sound driver output. This is a convenience element for Out with the ability to provide a set of discrete indices to which corresponding channels of the input signal are mapped, whereas multichannel expansion with respect to the index argument of Out typically do not achieve what you expect.

If SuperCollider runs with less physical outputs than requested by this UGen, the output is muted.

Examples

// flip left and right when writing a stereo signal
play {
  val indices = Seq(1, 0)
  val in:GE   = Seq(SinOsc.ar * LFPulse.ar(4), WhiteNoise.ar)
  // sine appears on the right channel, and noise on the left
  PhysicalOut(indices, in * 0.2)
}
