Send the output of this UGen to another UGen, UGenInput, or AudioOutput. For instance, if an Oscil is patched to an AudioOutput, you will hear the sound it generates. If a FilePlayer is patched to a Delay, then the delay effect will be applied to the sound generated by the FilePlayer.


UGen patch(UGen connectToUGen)
UGen patch(UGen.UGenInput connectToInput)
void patch(AudioOutput audioOutput)


connectToUGen — The UGen to patch to.
connectToInput — The UGenInput to patch to.
audioOutput — The AudioOutput you want to connect this UGen to.


When patching to a UGen or UGenInput, the UGen being patched to is returned so that you can chain patch calls. For example:

 sine.patch( gain ).patch( out );



  * This sketch demonstrates how to create a simple synthesis chain that 
  * involves controlling the value of a UGenInput with the output of 
  * a UGen. In this case, we patch an Oscil generating a sine wave into 
  * the amplitude input of an Oscil generating a square wave. The result 
  * is known as amplitude modulation.
