Simon the Magpie built a device called MIDI TO RESISTANCE that converts MIDI note data into variable resistance, placing it inline with circuit-bent connections to give pitch-bending toy circuits precise, repeatable musical control via a digital potentiometer.
The problem it solves is real: circuit bending produces interesting sounds but resists musical structure. By replacing a physical pot with a digitally controlled equivalent driven by MIDI input, Simon turns chaotic pitch bends into playable, keyboard-driven performances. The demonstration on pitch-bent toys is the argument, and it works.
The original is worth watching in full for the implementation details, specifically how the digital potentiometer is wired into existing bend points and how MIDI data maps to resistance values across the pitch range. If you work with bent instruments and want repeatability without gutting the weirdness, this build is the model.
