SS30-M - A Yamaha SS30 in a rack-mount, with MIDI, is a blog dedicated to the construction of a rack mounted Yamaha SS30-M, analog string synthesizer. There are a couple of YouTube links in the top post but they didn't work for me. If they do for you, post a comment. Be sure to scroll when you get there to see prior posts.

Quad Voltage-Controlled Resonant Bandpass filter (VCRBPF)
The Plague Bearer’s patchbay is designed to fit the most patch options possible in the small space available. Each filter has four Input/Output (I/O) connections: High CV, Low CV, Signal In, and Signal Out. Each of these has two jacks, one 3.5mm phone jack for external signals to avoid floating grounds, and one 0.080” tip jack for internal patching between filters. Each pair is direct-connected as a multiple – NOT a summing node! I have found this setup to be the most fun!
