The Georgia Tech Center for Music Technology's annual Margaret Guthman Musical Instrument Competition is a platform for bringing like-minded inventors and composers together to develop their ideas and careers. Sergi Jorda (left), inventor of the reacTable tabletop musical instrument, served as a judge in the third annual competition. Second prize winner MindBox Slot Machine was commended by the judges for its “ingenuity for instrument design.” Berlin based artist and composer Christain Graupner (right) accepted second prize for MindBox Slot Machine, an instrument encased in a vintage slot machine and plays music based on the idea of the canon composition, where three discrete voices represented by the three slots are controlled independently. See the demo. MindBox is produced by Humatic Verlin in cooperation wtih TMA Hellerau and Compagnia Zappala Danza.
