PURPOSE:To obtain musical tone characteristics which are close to those of a natural musical instrument by delicately controlling the characteristics of a musical tone generated by fuzzy inference based upon a breath force and a lip force as input parameters. CONSTITUTION:A breath controller part (breath information detecting means) 2 outputs a control voltage corresponding to the pressure of breath blown to the mouthpiece part 1a of a musical instrument body 1 as breath information and a lip controller part (lip information detecting means) 3 outputs a control voltage corresponding to the biting pressure of lips to the mouthpiece part 1a of the musical instrument body 1 as lip information. Then a CPU 7 receives the breath information, lip information, and key information from the breath control part 2, lip control part 3, and a key operation part 6, performs necessary processes for controlling the characteristics of the musical tone to be generated according to a combination of the breath force and lip force by the fuzzy inference based upon a specific program stored in a ROM 10, and supplies control data to a PCM(Pulse Code Modulation) sound source 11 of one system. |
