Yes.  Try something along the lines of this here:

(with-sound (:channels 2)

  ;; create temporary-file to work with later in note-list
  (sound-let ((tmp-file (:channels 1) (stretch-ins "somefile" 0.7)))

    ;; some instrument-call:
    (myins 0 4 440.0 0.1)

    ;; print info of tmp-file:
    (clm-print "~%tmp-chans: ~A" (sound-chans tmp-file))

    ;; put tmp-file to use in your main sound-file:
    (scramble-file tmp-file :scramble .5 :pan '((.8 .6)))))


sound-let deletes all files it creates before it exits, so youll
have to ask for information somewhere inside the body of
sound-let.  If you need to keep the 'temporary files after youre
finished, use a normal nested with-sound call instead.
