ABSTRACT:
Musical notes having time variant modification of the waveshape are produced polyphonically in a tone synthesizer by computing master and transient data sets, transferring these data to buffer memories, adding the data read out from the buffer memories briefly during a transient time interval and repetitively converting the summed data to waveforms. The master and transient data set are created repetitively and independently of tone generation by computing a generalized Fourier algorithm using stored sets of generalized Fourier coefficients. Circuitry is disclosed for independently applying Attack/Release modulations to the principal tone generated from the master data set and to the transient tone generated from the transient data set.
