[CM] poly questions

[bil at ccrma.Stanford.EDU]

Here's an example using polywave:

(let ((g (make-polywave 100 '(1 1 3 1/3 5 1/5 7 1/7 9 1/9)
             :type mus-chebyshev-second-kind)))
    (with-sound ()
       (do ((i 0 (+ i 1)))
          ((= i 44100))
          (outa i (polywave g)))))

You need to set the type to the second kind to get a sum
of sines, rather than cosines.

There are examples of the other generators in snd-test.scm.
