Famouse youtube user and music robot aficionado BD594 did it again – he build an awesome glockenspiel bot. Its remarkable, that he used a systems where one beater is responsible for a set of tones – and not one beater per tone as in similar instruments. This concept has the advantage of beeing much nicer to watch because the instrument has big movements – but the disadvantage that you probably cannot play it live because the latency gets too big.
User [BD594] is famous for releasing his “Old School Computer Remixes”. The remixes commonly feature a printer re-using the noises made by the step motors, some solenoid driven instruments and one or more oscilloscopes to visualize the sound of the stepper motors.
