Pluck, ring, rub, bang, strike, and squeeze are all simple gestures used in controlling music. A single motor/encoder plus a force-sensor has proved to be a useful platform for experimenting with haptic feedback in controlling computer music. The surprise is that the “best” haptics (precise, stable) may not be the most “musical”. Author Keywords Music control, haptic feedback, physical interaction design. ACM Keywords Input/output devices, interactive systems, haptic I/O. HAPTICS IN MUSIC Since 1978, Claude Cadoz [1] has used an active forcefeedback keyboard to explore the “instumentality” of dynamics in computer music. At Stanford’s Center for Computer Research in Music and Acoustics (CCRMA), Brent Gillespie [2], built a piano-like keyboard and solved some of the control problems. Chris Chafe and Sile O’Modhrain have shown the value of haptic feedback in faster response and more accurate modulation [3,4]. Charles Nichols [6] has built a force-feedback violin bow using...
