Photo-Journal of a rather twisted MBSID build :)

Thanks a million for the reply, it helps a lot. The thing is, I haven't finished my MB SID build yet, so I think I might go ahead and finish it off and think about a filter later! At least it seems easy to integrate it into the synth at a later date, and I'll have room in my casing for it anyway.

Out of curiosity, why did you decide to go with the SSM over the Steiner VCF? I'm looking at the Steiner myself as an option.

I tried with the Steiner first, it is quite noisy, it is not so steep (I think it is 12 or 18db/oct), and it doesn't offer CV input for resonance (cutoff only).

Look at the bottom of your PCB. I saw a picture here on the forum and it looks like it has a ground loop around the edge of the board. Maybe a trace cut can help with the noise.
