Older project of mine, that I scraped later on and reforged it into the Cigar Box Zynthian project. The idea was to have an physical extension to the Ardour DAW I use on rehearsals, that would allow me precise and comfortable control over MIDI parameters and also would enable me to have some kind of unusual input(hence the joystick and sonar module). Somewhere along the way I realized having standalone portable synthesizer is much better option and I went for the Zynthian build.
