net.beadsproject.beads.ugens.CrossFade
public class CrossFade
CrossFade is used to quickly crossfade between elements. Add it to the signal chain and
simply call fadeTo(UGen, float)
to fade to a new UGen
over a given duration.
Note that UGen has it's own simpler crossFade method.
TODO: non-linear fades.

fadeTo(UGen target,
float crossfadeTimeMS)
Cross fades from the current UGen to the specified UGen the specified number of milliseconds. |
void |
setPauseAfterComplete(boolean pauseAfterComplete)
Set whether this CrossFade is set to pause outgoing UGens once they have been faded out. |

UGen
UGen.bufIn
and putting data
into UGen.bufOut
in some way. UGen.bufIn
and UGen.bufOut
are 2D arrays of floats of the form float[numChannels][bufferSize]. The length of the buffers is given by
UGen.bufferSize
, and the number of channels of the input and output buffers are given by UGen.ins
and UGen.outs
respectively.
