Adapted from my ATtiny85 Synth Cable this code turns an ATtiny85 into a tiny MIDI-to-CV converter that can fit inside the case of a Korg Monotron to give it MIDI input. Like the synth cable, it supports pitch bend, modulation and an arpeggiator, and also can optionally retrigger the Monotron's LFO.
It uses dual PWM outputs to simulate a higher resolution, you could potentially expose the trimpot so as to make the pitch-bend range adjustable. I also recommend a trimpot for tuning, as this can drift with temperature. If done correctly this modification should not affect any of the Monotron's original functionality.
