The goal is to be a completely self contained performance instrument with purchase part cost of $100 or less. No cheating the budget by just building a controller and using a PC with a soft synth.
Current rough concept is:
- DIY ribbon CV controller: https://synthhacker.blogspot.com/2016/03/diy-midi-ribbon-controller.html
- A Korg Monotron or Gakken SX-150 modded for CV
My goal is to keep it analog, but alternate sound generation options are
- Arduino based synth
- RasPi with SunVox (via MIDI instead of CV)
- One or Jan Ostman's synth chips
