:) luckily I could strip those last two...
however, one option I had in mind was to _control_ the gluiph from a
PDA, although my idea of a musical instrument really is not to stare
at a GUI

hmmm, but if you stick with the default TIMEUNITPERSEC of 32*441000
you have overflow after 304 seconds, no ?

yep, that's right, my floats are just as fast as my ints

indeed. and as I said, if I can help with a cleanup, let me know
Miller. Partially I already had to do it anyway, and if it helps more
people than myself, maybe it should find its way into the canonical
(adopting CSound speak here) release.
