PURPOSE:To obtain the change in the musical tones meeting the change in the state of tone holes at the time of the actual blowing of a wind instrument by gradually changing tone hole information from the open state to the close state or from the close state to the open state in accordance with the opening and closing operations of the tone holes. CONSTITUTION:This synthesizer has 1st and 2nd signal processing means, a junction JA1 for signal scattering and a tone hole information generating means 21 which generates the tone hole information changing gradually from the close sate to the open state in accordance with the opening and closing operations of the tone holes. The coefft. to be used for the arithmetic processing in the junction JA1 for signal scattering is changed according to the tone hole information generated from the tone hole information generating means 21. The output signal from the junction JA1 for signal scattering, therefore, changes according to the tone hole information and the musical tone signal generated in this musical tone synthesizer changes. The change in the musical tones in the case of gradually opening or closing the tone holes by fingers is reproduced in this way. |
