A Tangible Virtual Vibrating String A Physically Motivated Virtual Musical Instrument Interface
Edgar J. Berdahl, Julius O. Smith · 2008
We introduce physically motivated interfaces for playing vir-tual musical instruments, and we suggest that they lie some-where in between commonplace interfaces and haptic inter-faces in terms of their complexity. Next, we review guitar-like interfaces, and we design an interface to a virtual string. The excitation signal and pitch are sensed separately using two independent string segments. These parameters control a two-axis digital waveguide virtual string, which models vibrations in the horizontal and vertical transverse axes as well as the coupling between them. Finally, we consider the advantages of using a multi-axis pickup for measuring the excitation signal.
