Melx, you are gentleman and a scholar. Thanks for offering :thumb:

I happened to have an old momentary footswitch lying around, and I had a couple of old pancake style stereo plugs. I just soldered it together tonight, and presto… I have a reset switch that resyncs these machines. I just tested it out, and it works a charm.

And thank you, Cryabetes, for the momentary switch idea. Brilliant.

According to http://en.wikipedia.org/wiki/CV/Gate

“Gate (Trigger) also has two implementations:

V-Trigger (“voltage trigger”, sometimes called “positive trigger”). This method involves keeping normally low voltage (around 0 V) on trigger and producing a fixed positive voltage to indicate a note is on. The amount of voltage required differs from synth to synth, but generally it is from 2 to 10 V. V-Trigger is used by Roland and Sequential Circuits synths, among others.

S-Trigger (“short circuit trigger”, sometimes called “negative trigger”). This one involves keeping voltage high normally, shorting the trigger circuit whenever the note should play. S-Trigger is used by Moog, Korg and Yamaha synths, among others.

Depending on the voltage level used, using the wrong combination of triggering mechanism would either yield no sound at all or would reverse all keypress events (i.e. sound will be produced with no keys pressed and muted on keypress).”

So when if connect a cable to the Clock In of the DRM 15, and I hold the bare plug, the DRM 15 stops. When I release it, the DRM 15 starts again. So is that V-Trigger or S-Trigger?

I’m guessing that it is V-trigger, thinking that my hand is sending a low voltage current to the DRM 15, thus triggering it on.
