This is video I recorded of a recent tour of the Moog Music Factory in Asheville, NC. Sorry, but I did not get the entire tour filmed.

"It really does remind me of the Octave Cat color scheme...

you can see that I used the membrane now only as artwork. I drilled through the membrane and the chassis control panel. I then rewired the entire matrix to the switches, and terminated that in a ribbon cable, with a connector. I replaced the membrane multipin connector on the left upper panel PCB with a mating connector for the ribbon cable. All the LED function was on the PCB, so that didn't require changes.

Those white actuator UID switches are NOT easy to find!"

Sequential Circuits Studio440 Resonance Mod

Middle: "CEM3389 Mod Schematic

This shows the CEM3389 datasheet schematic, with 7 of the DIP headers that form part of the socket adapter on the left, and the basic schematic on the right. NOTE: the resistors used were different than I labeled here!"

Bottom: "CEM3389 DIP Header Circuit Adapter Sockets

Again the schematic, but with 3 views of the completed socket adapter. Basically, the DIP header has a wire which routes the panning CV over to the resonance pin of the IC - note that I cut the pin off the DIP header that went to the resonance pin, because the Studio440 PCB runs that to ground.
On the IC socket, all pins are soldered to the DIP header EXCEPT for the panning pin, which is lifted out to the right. That is then soldered between two resistors, one that goes to ground and the other that goes to +Vsupply. Esssentially, it's a voltage divider that ties that pin to a fixed voltage right about +2.5V which balances the L-R output of the CEM3389. You can see those resistors configured to the socket adapter in the pic."
