PURPOSE:To easily fine musical sound control at a high speed by employing fuzzy inference to determine a musical sound control parameter. CONSTITUTION:A keyboard 1 has keys corresponding to pitch values and the states of sensors for the respective keys are detected by a key-on detecting circuit 2, an initial touch detecting circuit 3, and an after-touch detecting circuit 4. Then they are inputted to a musical sound control parameter inferring circuit 5 composed of a fuzzy inference circuit and the circuit 5 infers a pitch, a vibrato, fluctuation, and level according to the input signal and outputs the respective control parameters to a signal generating circuit 6. Consequently, the fine musical sound control is enabled by the simple constitution and the processing speed is never reduced. |
