(BTW: I use two EDPs. I use three footswitches in a daisy chain. Each footswitch can control either unit A or B, but not both simultaneously. I haven't needed this functionality except in one instance; I'd like to MUTE both loopers simultaneously at the end of a composition.) RE: controlling two EDPs with one footswitch - The EDP is simply using the resistors in the footswitch as one leg of a voltage divider. If you have a three position switch (i.e., A, B,A+B), I'd think the A+B position could switch a single resistor into the circuit such that both EDPs see the correct values of the other resistors. I haven't computed the value, but I think this should be possible. This set-up would not require DPDT switches. RE: controlling more than two EDPs - At some point, I want at least one more EDP, probably two more, so I've thought some about how to control them. For me, I think MIDI footpedals are the best solution. As the discussion over the A+B function shows, with multiple EDPs the player will probably want combined functions. This can get out-of-hand (pun intended) with the non-midi footswitches. 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." The MIDI pedals I've seen aren't adequate for this function. It seems that I need some kind of sequencer to send out MIDI messages to simulate a "long press." Am I mistaken? Has anybody else solved this problem? Kim! How about a simple <bg> software mod that upon receipt of a particular MIDI command would simulate a "long press"?
