I built this today and it's working! It's a good bitcrush/ringmodish type effect.
Thanks for the layout, excellent work!

Just one small thing, Blend 1 & 3 needs to be swapped.

There are a few observations I'd like to mention for anyone else building this. I had to spend alot of time setting up the circuit to get it to work as it should. For a good while I thought that it wasn't working at all (only got clean signal), until I set the controls right. Hence, a few of the controls definitly needs to be trimpots aswell..

The width pot - it needs to be set just about center for the circuit to work at all.. There is a small area of the sweep (about 40/60 - 60/40 ratio) where it sounds like it should, but outside that small sweep it's just clean signal. I think this pot would be better as a trimpot (set and forget).. I tried different value pots, but it doesn't seem to matter, just the ratio.

The gate pot is also a set and forget control. It needs to be set just right together with the threshold. With the threshhold too high there is only clean signal, set too low and the gate is not working.. set the gate to low and there is alot of noise coming thru, and set it too high the gating will have a too long releasetime.. Both of those controls are very interactive and need to be set exactly right (the sweetspot for both pots are very small and a bit hard to adjust).

I redrew your layout slightly with trimmers insted (I hope you don't mind)



With multiturn trimmers, such as these you will get a better tuning of the controls and it will still fit on the board.

Thanks again for the layout :)
cheers
