I don't think the doepfer A-122 have CEM3320s anymore which leads me down the DIY route. What CEM3320 VCFs are there out there? Erica Synths Multimode and GStorm Electro, any others

It just came to my attention that there's the Alfa AS3320 chips. If anyone has comparisons of the Alfa's vs originals, please post them here.

There's the Digisound 80-6A filter(s).
I made a eurorack adaptation:

It is possible to build it as either a Low-Pass, High-Pass, Band-Pass or All-Pass filter.
PCB and panels available.
Assembled modules on request.
