[CM] Snd + Jack, multiple file playback and recording

[Bill Schottstaedt]

snd-rt is probably the right thing, but if you want to use Snd,
get the current tarball or CVS version (the stuff in the earlier
play.scm seems to be broken), and:

(bind-key #\o 0 
  (lambda () ; send oboe.snd to chan 0
    (play "oboe.snd" 0 #f #f #f #f #f 0)))   ; how many #f's??

(bind-key #\p 0 
  (lambda () ; send pistol.snd to chan 1
    (play "pistol.snd" 0 #f #f #f #f #f 1))) 

;;; Now open a sound (so you have a non-listener pane to type to)

(play #f 22050 2) ; srate 22050, 2 output chans

;;; this holds the DAC open indefinitely
;;; Now type o and p in the sound pane until you want to quit, then

(stop-playing)
