You could "cheat", taking an engineer's approach: plot tendency toward
runaway feedback against some appropriately chosen paramater values, use
the data to aid in constructing a feedback gain modulator. If the system
is predicted to run away for certain parameter values, maybe nudge the
gain down a bit. A properly chosen modulation scheme may even allow you an
additional quirky point of control over the "personality" of the
installation at any given moment. Depending on just what intelligence
extraction is going on as regards the fed in data, it might get hairy
automating gain control,
however, and even if an appropriate control scheme can be found it may be
unstable, even to the point of unusability in performance. Babysitting may
of course be required.
Or maybe store known good samples for comparison with data under feedback,
choose where enough tonal/... difference is enough?
hope this helps
