Diapasonix

Description

Diapasonix is a portable electronic musical instrument and MIDI controller that is played similarly to a stringed instrument. It features a capacitive touchpad fretboard, I²S audio output, and a built-in synthesizer with chainable audio effects powered by the AMY synthesis engine.

Its four-string, six-fret layout (24 touch points total) can be set up to match traditional stringed instruments like guitar, bass, ukulele, violin, double bass, banjo, and so on. If you can play any of these instruments, you can play Diapasonix!
