FWIW… I took apart my Roland EV-5 Expression pedal to trace out the wiring (not a clue if this works with the Maestro. Suspect it would). I measured the potentiometer values as there were no markings on them. For how it works I don’t think the value of the main potentiometer is too critical as all it does is function as a voltage divider to the voltage applied across the ends of the pot. I don’t know if the pots are linear or log, but would suspect linear.
I’m thinking about building a desktop expression controller with a standard rotary pot in a project box which could be handy at times with a Hotone Ampero Control. If you have some soldering skills it would be cheap and easy to experiment with some potentiometers wired out to a TRS cable.
Both the Maestro and the Aeros have expression pedal inputs. You would almost think Singular might consider manufacturing their own and selling it as an accessory. That way you could be sure it worked with their product line. Or work a deal with another manufacturer and rebrand an exp pedal with the Singular Sound logo.
