Sorry for faux-reposting this, but I have made some progress. I have determined the DIN connections for the synth, but I don't know what power supply I need.

Keep in mind, the DSM2 is a dual analog drum module, so power is obviously going to two modules. By testing the power indicator LEDs using a 9-volt battery, here's what I found:

Pin 1: negative for modules 1 and 2
Pin 2: not connected/ground
Pin 3: ground
Pin 4: not connected/ground
Pin 5: positive for modules 1 and 2

Seems easy enough, but what next? The DSM2 uses 5 LM13700N ICs per module. On its datasheet, the LM13700N has a 10V Supply Min and a 36V Supply Max.

I've included a YouTube link to someone using the full DSM module:

The MPC Electronics DSM2 drum synth module that was designed to go with a master unit. The master unit provided power to it via a 5-pin DIN cable. You can view a YouTube video of someone using it here: http://www.youtube.com/watch?v=QPe6-FhTBko
