ABSTRACT:
Musical tone signals are produced in an electronic musical instrument by calculating the amplitudes at successive sample points of a complex waveshape and by delivering these calculated amplitudes one after another in time sequence. A recursive algorithm is implemented to calculate each amplitude, using one or more sets of parameters and also the calculated amplitudes for a plurality of the preceding sample points. This musical instrument can produce a variety of musical sounds which realistically simulate those of the various existing natural musical instruments including percussion instruments, simply by suitably determining the parameters.
