I got my first VCF finished. I didn't have a 3.6k for the gain of the feedback section, so I used a 3.3k. The resonance has the signature Steiner bite, but comes in smoothly. Very nice. As soon as I get the VCO and VCF in the rack, I'll be able to more easily get some sound samples up.

I initially used all discrete transistors, then swapped in an SSM2210 for the pair below the series diodes. I heard no discernible difference but will probably just leave the SSM2210.

You can see where I used discrete transistor instead of the second SSM2210 and the 3.3k resistor standing up so I can pull it easer when I get the 3.6k.
