We saw the first version of Peter Wiessenthaner’s Electronic String Instrument back in 2020, but Peter and his collaborators are back with a new version 2.0.

Improvements include 189 RGB LEDs to provide feedback to the user, as well as new tuning systems which are represented by distinct LED colors. A Kinect V2 camera provides gesture control. The Teensy 3.6 takes the camera input data from a laptop and controls five motors and the LEDs. New programs allow traditional playing of the instrument or guided playing by following the LEDs, as demonstrated in concert performances and public exhibitions throughout Europe and the US.
