Georgia Tech has announced the finalists in its annual Guthman Musical Instrument Competition. Unlike most of the rest of the finalists, it’s already a commercial product you can purchase from Eternal Research for $999. Beyond turning invisible EMF into audible sound, it can also control other synths by converting the invisible radiation from your cellphone or TV remote into MIDI and control voltage (CV). Check out the video above for brief demos and details on all ten finalists. The winner will be announced following a competition concert on Saturday, March 14th.
