Claims

[Claims for Utility Model Registration] (1) Sound source means for producing musical tone signals; storage means for storing production control information; In the electronic musical instrument, the performance control means stores a fade-out control signal having a fade-out characteristic such that the amplitude gradually decreases over time in the storage means. Based on that fade-out control signal,
An electronic musical instrument characterized by comprising a fade-out characteristic imparting means for imparting the fade-out characteristic to a musical sound signal generated from the sound source means. (2) The electronic musical instrument according to claim 1, wherein the fade-out characteristic imparting means finishes imparting the fade-out characteristic to the musical tone signal based on the fade-out speed data read from the storage means. . (3) The electronic device according to claim 1 or 2, wherein the fade-out characteristic imparting means imparts the fade-out characteristic to the musical tone signal based on fade-out level data read from the storage means. musical instrument. (4) The electronic musical instrument according to claim 1, 2 or 3, wherein the fade-out characteristic imparting means includes an operator means for starting imparting the fade-out characteristic to the musical tone signal. (5) The fade-out characteristic imparting means has a measuring means for measuring a predetermined elapsed time after the performance control means starts the automatic performance, and the fade-out characteristic imparting means adjusts the fade-out characteristic to the musical tone signal based on the measurement data from the measuring means. 4. The electronic musical instrument according to claim 1, wherein the electronic musical instrument starts imparting characteristics. (6) The fade-out characteristic imparting means has a measuring means for measuring the number of tempo clocks after the automatic performance is started by the performance controlling means, and adjusts the fade-out characteristic to the musical tone signal based on the measurement data from the measuring means. Claim 1, 2 or 3 characterized in that the grant is initiated.
Electronic musical instruments listed.
