;; (local-in num-channels rate)

;; Define and read from buses local to a SynthDef

;; num-channels - the number of channels of local buses.

;; Localin defines buses that are local to the SynthDef. These are
;; like the global buses, but are more convenient if you want to
;; implement a self contained effect that uses a feedback processing
;; loop.  There can only be one audio rate and one control rate
;; Localin per SynthDef.  The audio can be written to the bus using
;; local-out.
