I’ve completed a DIY project modding the Korg Monotron for analog CV input. I have found some other descriptions of similar mods online, but so far as I know I’m the first to document the build on video or provide PCB layouts, so while monotron hacks may be old hat, I think this brings something new to the table.
With full credit to DINsync for documenting and experimenting with CV input to the monotron, I developed a new circuit using a simple potentiometer and transistor design to combine gate and pitch into a single “gate/pitch” signal to feed into the monotron.
This project received coverage in CreateDigitalMusic and MatrixSynth.
