The electronic accordion can play warp-speedy tempos by means of its integrated rhythm machine. Inside its belly, there is an optical system that modulates the pitch of the sound as well as the frequency rate of the rhythms depending on the movement of the bellows. The performer can play melodies with the seven functional buttons (untuned oscillators) and accompaniments with the other three buttons (multiple oscillators modulated in a cascade).
