You're much better off with one voltage divider circuit and buffering it with an opamp to the other units. >RE: controlling more than two EDPs - >When I look at controlling ALL the front panel functions via MIDI, I >haven't >been able to find a simple solution to the "long press."

Has anybody else solved this problem? my midi pedal does this, no problem. (digitech PMC-10) Any pedal that can treat the switches as momentary will work, where it sends one command when pressed and another command when released. (NoteOn when pressed, NoteOff when released, etc....) There are quite a few pedals that do this, some examples are Rocktron AllAccess, Roland FC-200, bass pedals for organ, etc. Not to mention any keyboard midi controller. Even a simple pedal like the Ground Control can do this in limited fashion, using a momentary switch in the CC inputs. (pressed it sends CC=128, released it sends CC=0, with the echoplex set to use CC messages for control.) of course, you only get 2 or 3 CC inputs, usually... >Kim!
