final case class InFeedback(bus: GE, numChannels: Int = 1) extends MultiOut with AudioRated with IsIndividual with Product with Serializable

A UGen which reads a signal from an audio bus with a current or one cycle old timestamp.

Audio buses adhere to the concept of a cycle timestamp, which increases for each audio block calculated. When the various output ugens ( Out , OffsetOut , XOut ) write data to a bus, they mix it with any data from the current cycle, but overwrite any data from the previous cycle. ( ReplaceOut overwrites all data regardless.) Thus depending on node order and what synths are writing to the bus, the data on a given bus may be from the current cycle or be one cycle old at the time of reading.

In.ar checks the timestamp of any data it reads in and zeros any data from the previous cycle (for use within that node; the data remains on the bus). This is fine for audio data, as it avoids feedback, but for control data it is useful to be able to read data from any place in the node order. For this reason In.kr also reads data that is older than the current cycle.

In some cases one might also want to read audio from a node later in the current node order. This can be achieved with InFeedback . It reads from the previous cycle, and hence introduces a delay of one block size, which by default is 64 sample frames (equal to about 1.45 ms at 44.1 kHz sample rate).

Note that no delay occurs when the bus contains a signal which has been written already in the current cycle. The delay is only introduced when no present signal exists.

bus

the index of the audio bus to read in from.

numChannels

the number of channels (i.e. adjacent buses) to read in. Since this is a constant, a change in number of channels of the underlying bus must be reflected by creating different SynthDefs.
