Something I've been wondering about recently is this - if you implement
a digital filter, how do you maintain stability when it's pushed into
self-oscillation? Most "real" synths seem to put out a slightly clipped
sinewave when in self-oscillation. Might it be as simple as an atan()
clipper in the feedback loop?
