BeatyBeatyBeaty is a software based instrument for the live, improvised creation of rhythmically and harmonically complex music. It presents a multi-track graphical interface, onto which the performer draws probability curves representing various aspects of the sound to be created (temporal events, frequency and amplitude, panning, etc.) The results of the performer's actions are heard and seen instantly, allowing the intuitive development of performance techniques.
