OTA based Filter with low pass, high pass and 3 CV ins.

It´s mostly based on the original schematic with some level adjustments and a switch for the modes.

It does have a very gritty, screamy and unstable character which made it pretty famous.

After about 50% of resonance the madness begins 🙂 It goes into self oscillation but don´t expect proper tuning stability.

It is simply a very experimental piece of gear and if i should describe it with some words:

It sounds like a pissed and wet cat 😀
