Any Tone 2 Saurus users?

So that's a yes?

Y... ack the nonlinear and the feedback behaviors are functionally integrated in such a way that they can't be computed independently in series as is much more conventional in digital filters when there's 0-delay-feedback with multiple nonlinearities in the feedback block

Yes

Oh well, I guess it's beyond my O level maths... I thought feedback in physical systems was modelled using iterative functions, and polynomial equations don't look iterative to my untutored eye. But I'm getting that it's slightly more complicated than that.

Ah, there's a slight point here about polynomial time (operations required to achieve a computational result expressed as a polynomial per element n, something like n^3 (bad) or n log n (not so bad)) versus polynomial equations (which tend to be computable in polynomial time or approximated if there's transcendentals or it's some infinite series, but I'm just making excuses, I probably screwed it up a bit earlier in the thread )

Getting an iterative function that has good computational performance as well as numerical accuracy is I think the general gist of things, but again it's not the case that feedback and nonlinearity are cleanly separated in this sort of function. (I think there are some 'magic' numbers that sort of seed something about the function describing the filters that end up in the kinds of numeric solutions that Diva uses, as well, which have a pretty deep theoretical entanglement ...)

Oops, thats all about this great synth?

Yep like Saurus a bunch.

Thanks
I actually posted in that one myself last time ;o) I searched using the KVR search and only found this old thread.
