Abstract

We introduce physically motivated interfaces for playing virtual musical instruments, and we suggest that they lie somewhere in between commonplace interfaces and haptic interfaces in terms of their complexity. Next, we review guitarlike interfaces, and we design an interface to a virtual string.The excitation signal and pitch are sensed separately usingtwo independent string segments. These parameters controla two-axis digital waveguide virtual string, which modelsvibrations in the horizontal and vertical transverse axes aswell as the coupling between them. Finally, we consider theadvantages of using a multi-axis pickup for measuring theexcitation signal.
