Tone generation system.

Abstract

A real time tone generation system for synthesis of musical instruments comprises means (51) for providing a control signal for initiating and thereafter controlling generation of a tone, connected to wave transmission means (53) via a junction (52). The junction receives signals from and passes signals to the wave transmission means, the supplied signals being a function of the control signal and the signal received from the wave transmission means. Thus, the nature of the signal propagating in the wave transmission means depends on the characteristics of the wave transmission means and the junction means and the value of the control signal.
