Title:
SYCHRONOUS SIGNAL GENERATOR AND ELECTRONIC MUSICAL INSTRUMENT USING IT
Document Type and Number:
Japanese Patent JPS57136695
Kind Code:
A
Abstract:
A synchronizing signal generator includes a tape recorder which is adapted to record click signals in response to actuations of a manual switch. Counting clock signals go on while the click recorded signals are reproduced, especially during a length of time extending from receipt of a particular one of the click signals to receipt of the next succeeding click signal. The resultant count is divided by a given numeral value and then the quotient is stored. The clock signals developing between the respective click signals are further counted during the course of reproduction of the click signals from the tape recorder and a pulse signal is delivered whenever the instantaneous count coincides with the stored quotient. Tempo clock signals are obtained through the division of the pulse signal at a selected division ratio out of a plurality of division ratios. The tempo clock signals are fed to a sequencer which in turn generates a control voltage and gate signals synchronous with the tempo clock signals. A music synthesizer produces tone signals in synchronism with said tempo clock signals in response to the control voltage and the gate signals.
