These Musical Instruments of the Future Sound Weird, Wacky--and Are Easy for Anyone to Play

WIRED

A bicycle wheel with guitar strings, a touch-operated synth, and the "Demon Box" were just a few of the new instruments on show at Georgia Tech's Guthman Musical Instrument Competition this weekend. An open-source, touch-operated synth built to resemble a puzzle piece and keep accessibility at the forefront. A pressure-sensitive surface allows for polyphonic synthesis that can be triggered by hands, feet, textured fabrics, or even Play-Doh. Brand new sounds floated through a concert hall at Georgia Tech this weekend, as the 28th annual Guthman Musical Instrument Competition showcased an array of new instruments from around the world--and crowned one champion. Ten finalists, chosen from candidates who built all kinds of new music-making devices, converged in Atlanta, Georgia, to present their instruments to a panel of judges.

We propose stochastic ensemble value expansion (STEVE), a novel model-based technique that addresses this issue. By dynamically interpolating between model rollouts of various horizon lengths for each individual example, STEVE ensures that the model is only utilized when doing so does not introduce significant errors.
