Tbone55 Posted November 20, 2022 Share Posted November 20, 2022 I purchased a used Moog EP-3 expression pedal to replace the M Audio one I had but it's not controlling the volume like it should. There's no response to the volume when rocking the pedal up and down. The volume is always on and I can only control it using the volume knob on the keyboard. I went through the same procedure to set it up as I did with my M Audio pedal as shown in the manual on pages 9-10. I hooked M Audio pedal back up and it works fine. Maybe I bought a dud but before I contact the seller I'd like to know if anyone else has encountered a similar issue or maybe I'm missing something. Is there some kind of reset that needs to be done before I hook up the Moog pedal? Thanks Quote Link to comment Share on other sites More sharing options...
Tbone55 Posted November 21, 2022 Author Share Posted November 21, 2022 An update. So the guy that sold me the pedal didn't give me the cord that came with the pedal. A friend of mine picked up the pedal for me be ause he lived near the seller. I tried to use a guitar cable to connect the pedal but I now see that I need a stereo TRS cable. I didnt notice this until I looked at the cable that came with my M Audio pedal. I'm assuming that this how the pedal gets power. I've ordered a new cable as I don't have any that are stereo so this should fix the issue. Please comment. 1 Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted November 21, 2022 Share Posted November 21, 2022 The potentiometer in an expression pedal is a 3 terminal device, which is why the TRS cable is needed. 1 Quote Link to comment Share on other sites More sharing options...
