ChannelProxy

A helper graph element that selects a particular output channel of another element. The index is an Integer and thus cannot be determined at graph expansion time. If this is desired, the Select UGen can be used.

Usually the graph element operator \ (backlash) can be used instead of explicitly writing ChannelProxy. Thus elem \ index is equivalent to ChannelProxy(elem, index). UGens with a fixed number of outputs often have auxiliary methods to access the channels in meaningful way, e.g. Pitch has method freq and hasFreq, which are equivalent to pitch \ 0 and pitch \ 1.

Because ScalaCollider allows late-expanding graph elements, we have no direct way to get some array of a UGen's outputs.

Examples

// frequency of a pitch estimator
play {
  val sin = SinOsc.ar(MouseX.kr(10, 10000, warp = 1))
  val pch = Pitch.kr(sin)
  val freq = pch \ 0  // same as pch.freq
  freq.poll(label = "freq")
  ()
}

elem: a multi-channel element from which to select a channel.
index: channel index starting at zero. It automatically wraps around the actual number of channels the input elem expands to.
