@title{(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.
