A while back I floated a theory or two on how to improve ZynAddSubFX'
jack io. It has progressed to a fairly functional form, ie, no crackling,
and it generally keeps up with proceedings fairly well.
Thanks in no small part to the outstanding debugging efforts of James Morris,
most (if not all) of the accidental "colourations" to the generated sound
seem to have been resolved.
And the jack midi implementation no longer destroys the entire goal of jack
midi. I thought that was important.
Snapshot tarball at <http://www.graggrag.com/?q=node/19> for those interested.
Mark, if you're thinking of integrating the jack driver, I reckon this is
probably as good as I'm going to get it :-).
cheers, Cal
