摘要： A vocoder system for improving the performance expression of an output sound while lightening the computational load. The system includes formant detection means and division means in which the center frequencies have been fixed. The modulation level with which the levels of each of the frequency bands that have been divided in the division means are set by a setting means based on the levels of each of the frequency bands that correspond to those that have been detected in the formant detection means and formant information with which the formants are changed. Therefore, it is possible to improve the performance expression of the output sound with a light computational load and without the need to calculate and change the filter figure of each filter for each sample in order to change the center frequency and bandwidth of each of the filters comprising the division means.

摘要： A synchronizing signal generator generates synchronizing signals in synchronism with the performance of a musical piece even from an intermediate point of the musical piece. More specifically, upon actuation of a manual switch (102) in accordance with a musical piece, a code signal corresponding to a beat number is recorded in a tape recorder (200). At the same time, a clock counter (112) counts clock pulses during a period of time from the point where a code signal corresponding to the beat number is received to the point where the next succeeding code signal is received. A CPU (105) divides a count value of the clock counter by a predetermined numerical value so that a value obtained by the division is stored in a memory (114). When the recorded code signal is reproduced and applied to an input terminal (101), the CPU identifies a beat number from the reproduced code signal and delivers a step number signal corresponding to the beat number and a sequencer start signal to a sequencer (300). During a period of time from an identification of a beat number to the identification of the next succeeding beat number, the clock counter counts clock pulses and the CPU provides synchronizing signals when a count value of the clock counter becomes equal to the value stored in the memory.
