ABSTRACT:
A keyboard operated electronic musical instrument is disclosed which has a number of tone generators that are assigned to actuated keyswitches. Musical tones are produced by computing a master data set which defines the data points corresponding to a period of a musical waveshape. The master data set points are read out sequentially and repetitively from a memory and converted into an audible musical tone. Circuitry is provided whereby the master data set is computed from a time sequence of harmonic coefficients which is modulated to produce a musical tone having a time variant spectra.
