[Anders Vinjar]

Theres no output coming out of convolve in recent clm.  Either
from the ug, or from using #'convolve-files.  Heres the output
from running the first example from clm-2/cnv.ins, the instrument
using #'make-convolve and #'convolve:

(with-sound (:output "CNV/1.snd") (outa 0 .5) (outa 3000 .5) (outa 10000 .5))
(with-sound (:output "CNV/v.snd") (fm-violin 0 1 440 .1 :amp-env '(0 1 100 1)))
(with-sound (:statistics t) (cnv 0 1 "CNV/1.snd" "CNV/v.snd"))

* test.snd: 
  Duration: 1.0000, Last begin time: 0.0000
  Compute time: 0.180, Compute ratio: 0.18
  OutA max amp: 0.000 (near 0.000 secs)
