Fretboard
Spectral synthesizer optimized for touchscreen. This app allows you to play the multitouch screen fretboard like tapping a string instrument and control the sound. Written in Javascript using Web Audio API, works in most browsers.
Bugs
After the same key is pressed with two fingers, its sound mutes shortly after the start of note.
TODO for beta:
MIDI in/out to and from DAWs (16 channels for microtonality; read file ?) - midi_out.html
Touch radius / angle -> volume / pan or noise (?) of notes and harmonics (https://developers.google.com/web/updates/2015/07/rotationAngle-and-touchRadius)
touch sensitivity (both coordinates + velocity + rotationAngle)
noise and detune of harmonics (formants.html for noise generator)
spectrum controlled in realtime by filters, can emulate formants on linear scale - switch like with piano/string
Android / iOS app, promote with Wizdom Music ? (https://www.wizdommusic.com/)
