Troubleshooting the MIDI Maestro EXP Pedal

Even if the jack is a TRS, it doesn’t tell anything about the required wiring, internal resistance nor the best/expected taper type :thinking: So it actually doesn’t tell anything at all, except that the jack is a TRS :sweat_smile:

If MM would ignore the ring from the TRS jack then it would expect a TS plug. It would make sense if the functions of tip, ring and sleeve could be programmed in a firmware update to support all the possible exp options :relieved:

One question is that even though there is calibration, the range of supported internal resistance could still be limited :thinking:

Edit: The TRS jack does imply that a TRS plug is required, but that’s all that it does :yum:
