Instrument maker Frank Piesik created this unique MIDI-controlled robotic string instrument, Greg’s Harp.
The instrument takes incoming MIDI, analyzes it and translates the notes into signals to control actuators on three strings. The instrument uses multiple types of exciters, allowing for flexible performance technique. Pitches are controlled by ‘robo-fret’ tuning mechanism.
“Greg’s Harp is a new string robot I made for my friend Gregor,” notes Piesik. “This is my first attempt to combine three string units to make a polyphonic instrument.”
