ABSTRACT:
A method and apparatus for generating tone signals for a musical instrument, especially an electronic organ, in which a stable high frequency source which is equal in frequency to that of a reference pitch multiplied by a large whole number is divided down by a number differing a predetermined amount from the large whole number, and the thus divided down frequency is supplied to a phase lock loop which, in turn, supplies a synthesizer which will develop a range of pitches over a musical scale. By further dividing down the synthesized pitches, octavely related pitches can be obtained for the supply of pitches in conformity with the number of playing keys in the instrument and the number of ranks of pitches desired. The thus generated pitches differ slightly from the reference pitches by being either somewhat sharp or somewhat flat and when combined with the reference pitches produce desired effects.
