Abstract

1374539 Electrophonic musical instruments NIPPON GAKKI SEIZO KK 3 March 1972 [5 March 1971] 9985/72 Heading G5U A tone source device for electronic musical instruments comprises a master oscillator M, which produces a signal the frequency of which is divided down in a series of N frequency dividers to produce a corresponding series of notes over one octave of the chromatic scale. The frequency divider circuits each include m counter stages, the "bit number", the number of which required for each circuit being minimized by dissolving the frequency dividing ratios into a number of common factors so that certain frequency dividing stages are common to several notes.
