For what I could see, the SVF3 filters in Multipoly do not hop the coefficients. Haven't checked your other synths, but I am sure they don't hop(128) when modulating at audio rate. Else you'd have noticed.

I think what I'm beginning to realize is that in a few recent cases, I've used a different version of the SVF that I got from somewhere that are not the original SM SVF. Someone wrote a different code but the module's still named "SVF 3" !

Thanks so much for your detective work !

Since the SVF3 is so popular I have fixed the tuning. It wasn't off by much, but now it is supposed to be accurate enough to use it as an oscillator. I have also fixed the coeff update code whihc was a bit awkward.

Happy filtering!

What is the upper left text supposed to say on the Spirit of spirit GUI shown here.

Just noticed more GUI / text problems on spirit of spirit, what is it supposed to say above the grey switch shown here ?

Wow - thanks for doing that !

Thanks for pointing that out - short answer : GUI burn-in issue (as you probably suspected).
- long answer : I'd inadvertently left the label in the schematic after doing the burned-in
image containing all the unusual text. Since it was superimposed on the burned-in
image and my computer was rendering the schematic label correctly, the label was not
visible. Since your computer was rendering that text with a different font you got the
scrambled appearance - two fonts on top of each other.

I don't suppose you still have Synthmaker lying around to save that with ? I don't have FS.

Or maybe just post the code and I can paste it in.

Thanks again.

Here you go

You are a prince - thank you so much.
