Blacet Filthy Filtre dither trimpot

Has anyone with a Filthy Filtre messed around much with the dither trimpot in the VC Mode circuit? I know it goes from straight-up switching to some degree of dithering, and I'm wondering how useful people find it.

Does it provide actual crossfading between modes, or is it just the amount of overlap between adjacent modes?

I'm currently on the fence about picking up a Filthy at this point (though I may still get one down the road), but the VC Wave is perhaps the most interesting part to me. I'd be much more interested if the dither control provides cross-fading, and if that's the case I'd mod it with a pot on the front panel.

This seems to be one of the few trimpots settable to "user preference" that hasn't been discussed here as far as mods go.

Page 5 explains calibration.

I'm aware of the calibration details (that's how I found out about it), but it doesn't answer my questions.

I think the answer is that crossfading and overlap are really the same thing.

I think the answer is that crossfading and overlap are really the same thing.

By "just [...] overlap" I mean that it is still just switching, just with an overlap, so during the entire overlap each signal is 50%.
Crossfading would go continuously from 100%/0% to 0%/100% during the overlap.

OK, lets say it is crossfading during the transition band.

This is a middling pitch saw wave, fed thru the filthy filtre with middling cutoff and a little bit ov "q". The filter mode is swept by an LFO tri wave set to a (guess) middling speed. Hear the effect as the trimpot is slowly tweaked from fully CCW to fully CW and back again! Personally, I just set mine to about 1/3 of the way up and leave it there, works OK for me.

Filthy Filtre is a really good SVF, I think. Wd love it if JB made a nice 4-pole LPF to go w it.

or perhaps a revised 5-pole Final Filter with parts that are still available.

switchable to HighPass for bonus feature creep. Dancing Star
