Trev, I have tried several times to use a continuous control pedal (a Roland volume pedal) with my Ground Control (software version 1.0) to control the volume on my Peavey ProFex (software version 1.3). The results have always been horrible. There's no noise, but you loose the smooth transition from minimum to maximum volume. It abruptly steps from one MIDI volume value to the next. I've used a volume pedal for a long, long time and feel like my guitar is missing a couple of strings when I don't use one. If anyone knows how to eliminate this stair-step, zippering, I'd be most appreciative.

I am having a much easier time getting my loops timed properly, and having control over my regeneration in echo mode given me a whole new lease on life/looping. I got a fairly descent deal on the GC too (found it used) and the ROM update (you have to run 2.0 or better, I think to have it work) was pretty cheap. Programming it is not tricky, just a bit tedious. The effort is worth it though. I heartily recommend on to anyone having trouble with the standard pedal, and I would be willing to give my standard pedal up to anyone who would want to pay for the shipping/cod/whatever. I get to keep the stereo cable, though, as it may come in handy for other things.... Trev PS- Is there any way to control the input gain via midi? I doubt it, but I would find it very useful. My old volume pedal works out ok, except for a bit of noise every now and then.
