Filter feedback

Glad to hear it!
If that's working well for your configuration, then I'd give it a go using one of the "soft-saturation" kind of distortion/limiter modules that are floating around ("tanh" is a common one that gets a few forum search hits). That should give the result even more of an "analogue" flavour, and with fewer hard edges to provoke aliasing.

Good call - I'll try that.

There is no simple general stability criterion for non-LTI systems (i.e. dynamic filters) because you have so many possibilities to consider, but it is known that certain topologies.

seems that there is a framework to analyse BIBO stability of a system

there is a few words on the subject on the music-dsp archive !

Thanks for the reference, Francoise. I browse the DAFX papers regularly, but this one somehow escaped my attention.
