I would use Ingen (formerly Om), but I do that anyway ;) A pulse oscillator with some more or less subtle pulse width modulation might be a good basis. Add (Bandpass filtered) white noise for a breathing sound. Now I don't know how a damaged reed sounds, I can only think of overblown flute or sax. Fast pulse width modulation (via a sine oscillator > 20 Hz) can add a metallic touch. The hard clipper or one of the tube amp effects, perhaps bandpass filtered might do something for the sound. For extra breakage, feed a tube amp back to itself (after a signal product with something like 0.1) A pitch envelope could be made to fade in on high velocity (fiddly business, though). Building such a patch can easily eat up most of the day, even if one already knows their way around Ingen, though :) -- Thorsten Wilms
