;; (disk-in num-channels rate bufnum)

;; Continously play a soundfile from disk. This requires a buffer to
;; be preloaded with one buffer size of sound.  The buffer size must
;; be a multiple of twice the synth block size. The default block size
;; is 64.

;; Note that disk-in reads the number of outputs to create from what
;; looks like an input, but it is not an input, and cannot be set
;; using a control.
