Howard Media Engineering Research Group Department of Electronics University of York Heslington York YO10 5DD UK Email dh@ohm.york.ac.uk Stuart Rimell Media Engineering Research Group Department of Electronics University of York Heslington York YO10 5DD UK Received 30 June 2003 Revised 13 November 2003 Electronic sound synthesis continues to offer huge potential possibilities for the creation of new musical instruments. The traditional approach is however seriously limited in that it incorporates only auditory feedback and it will typically make use of a sound synthesis model e.g. additive subtractive wavetable and sampling that is inherently limited and very often nonintu-itive to the musician. In a direct attempt to challenge these issues this paper describes a system that provides tactile as well as acoustic feedback with real-time synthesis that invokes a more intuitive response from players since it is based upon mass-spring physical modelling. Virtual instruments are set up via a graphical user interface in terms of the physical properties of basic well-understood sounding objects such as strings membranes and solids. These can be interconnected to form complex integrated structures. Acoustic excitation can be applied at any point mass via virtual bowing plucking striking specified waveform or from any external sound source. Virtual microphones can be placed at any point masses to deliver the acoustic output. These aspects of the instrument are described along with the nature of the resulting acoustic output.
