An expressive multidimensional physical modelling percussion instrument

This paper describes the design, implementation and evaluation of a digital percussion instrument with multidimensional polyphonic control of a real-time physical modelling system. The system utilises modular parametric control of different physical models, excitations and couplings alongside continuous morphing and unique interaction capabilities to explore and enhance expressivity and gestural interaction for a percussion instrument. Details of the instrument and audio engine are provided together with an experiment that tested real-time capabilities of the system, and expressive qualities of the instrument. Testing showed that advances in sensor technology have the potential to enhance creativity in percussive instruments and extend gestural manipulation, but will require well designed and inherently complex mapping schemes.
