Claims (1)

[Claims for Utility Model Registration] (1) Sound source means that generates sound effects for each sound field channel using waveform data for the same sound source; and envelope generating means that gives a separate envelope to each of the sound source means. A sound effect generation device comprising: a sound generation control means for controlling sound generation of the sound source means. (2) The sound effect generating device according to claim 1, wherein the data of the envelope generating means are set separately. (3) The sound effect generating device according to claim 1, wherein the sound generation control means includes a sound generation start delay means that is set for each of the sound source means. (4) The sound effect generation device according to claim 1, wherein the sound generation controlled by the sound generation control means has a non-sustained sound. (5) The sound effect generation device according to claim 1, wherein the sound generation controlled by the sound generation control means has a continuous sound.
