DIY MIDI-Controlled Robotic String Instrument #MusicMonday

Frank Piesik has made a wonderful robotic stringed instrument. He made it for his friend Gregor, so it’s called Greg’s Harp. From Frank:

Since every moFret needs a dedicated servo and driver, we tried to keep the number of needed moFrets low but still enough to allow for playing every possible triad (e.g. c-minor in at least one inversion). We came up with four moFrets (equals five semitones) per string. The strings are tuned in major thirds, making them overlap one tone (so that string 1&2 and string 2&3 have one tone in common). A software algorithm takes incoming notes, analyses them and sends a playable inversion to the moFret controller.

See and hear more!
