Hello list, I'm still experiencing a very strange and intermittent problem with my EDP footpedal: When hitting Insert very quickly and repeatedly, it will occasionally trigger Multiply, and less occasionally Overdub. Here's what I've done to my footpedal over the last few days: -- Replaced every single switch with a brand new switch -- Replaced every resistor with a brand new resistor -- Put in a new jack -- Put in new wiring -- Re-soldered every connection, which in any event was newly soldered to begin with, since the various component parts being soldered together are all new In short, the only part of the old pedal I still have is the actual metal chassis. Everything else has been replaced, and I'm still getting the same basic problem. It's less pronounced that it was, but still very much present. The obvious answer would be that it's a problem with the EDP itself. Except... I've used a friend's footpedal with my EDP, and gotten this problem EXTREMELY rarely -- so infrequently that it hardly EVER happens. I also plugged my own problematic footpedal into his EDP, AFTER all of the modifications, and it behaves the same way in his unit as it does in mine. My pedal (and EDP) is an older Oberheim model, and his are Gibson models. But I've never noticed this particular problem prior to the beginning of this year. The only difference between the two footpedals is that my friend's newer model has insulation on the input jack, to keep it from connecting to the metal housing of the chassis itself. Even after modifying my unit with insulation, the problem persists. And I never noticed this for the previous six years that I've been using the pedal without insulation. Furthermore, Matthias tells me that, since the front panel buttons and the footpedal buttons are wired parallel, that any problem with the footpedal should be duplicated with the front buttons, and vica versa. When I do this test on the front panel buttons, it NEVER EVER happens at all. Not even ONCE. It's not a beta test issue, because I put Loop3 in and noticed the same thing (as well as my friend's unit, which is also on Loop3). So, I have two questions for the list: 1) Does anyone have any ideas as to what I should try now? 2) Can anyone with an EDP and a spare minute please perform the following test for me: -- Turn quantize off. Then press the Insert button on the footpedal as fast as you can, repeatedly (for 30 seconds at least). Watch the front panel display, and see if it goes into Multiply or Overdub at any point during this. I will assume that I now possess the EFC-7 equivalent of a Ouija board until such time as my pedal starts operating normally again... Big thanks for any ideas, and to everyone who already wrote in with suggestions. --Andre "Crowley" LaFosse http://www.EFC-7-busters.com
