MF-108M Patchbay

Post by krismiller1982 » Fri Mar 22, 2013 12:35 am

Wondering if anybody has had any success with making the dummy plugs for the Cluster Flux in a trs patch bay setting. I made 5 dummy plugs, all with the 1% 100k resistors soldered to the TR & TS. Still not functioning as if nothing was plugged into the unit. The LFO rate is definitely slower at max then with nothing plugged in. Any help/tips with making this function in a patchbay would be VERY VERY much appreciated!!

I also made these dummy plugs for the MIDI Murf and Clusterflux and wasn't that happy with it. I ended up going the other route mentioned in the Moog FAQ section and used 50k pots instead. I got some little trim pots and mounted them in a box. It was kind of overkill though, the kind you can get at Radio Shack worked great. Here's some pics of my project from start to finish. The potentiometer box is in the last few pics.

I didnt have luck with dummy plugs. I instead made a small voltage regulator circuit that tapped the 5V off the ring and converted it to 2.5 volts on the Tip. I mounted these to my patch bay and have worked fine for the past year or so (well, almost, the LFO amount needs a slight recalibrating that I havent done yet). Each PCB provides 2 circuits, so each jack on the patchbay is isolated (except I tied the ground together for simplicity).

@Shave - Any chance you could give instructions & parts for the regulator?
