IDD Summer 2017
Accidentally published before and don't have admin privileges to delete the repository... This is a keyboard that uses chording. It requires five fingers on one hand (designed for left) along with one right finger. It uses binary representation with five buttons to cover 29 unique gestures (27 letters of the alphabet, space bar, and backspace). I made this so that I could manipulate some parameter with my hand while being able to still manipulate other equipment (such as knobs on a distortion box).
