meloD is a 5-octave single-voice synthesizer that utilizes live touch and accelerometer data to control pitch and velocity. By placing a finger onto the chromatic fretboard, melodies can be played in tune with a dynamic range of expression and timbre.
To switch between free and chromatic operating modes, triple-tap the logo at the bottom-right corner of the screen. In Chromatic mode, the scale can be altered by tapping the notes on or off.
