R-FF: A Single Reed Haptic Library for the TorqueTuner

R-FF (Reed Force Feedback) is a library of clarinet reed equations adapted for use on the TorqueTuner (TT), a one degree of freedom, rotary force-feedback (FF), haptic device. We created the R-FF library by analyzing the clarinet's physical model and adapting the reed component that defines the forces between the user and the mouthpiece into force-feedback models. The models were designed for implementation on small and portable micro-controllers, like the ESP-32 module, found in the TorqueTuner(TT). Accompanied by a clarinet sound model, results show that the R-FF library could grow into a platform that allows non-wind players to explore the performance space of a single reed instrument, feeling the dynamics of the reed-embouchure system with their fingers instead of with their mouth.
