<P>PROBLEM TO BE SOLVED: To provide a musical sound generating device, which can generate a musical sound having channels more than channels limited depending upon the data transfer speed of a storage device according to waveform data stored in the storage device whose data transfer speed is slow, and to provide a storage medium. <P>SOLUTION: When a cache hit of waveform data whose sounding is indicated is detected, a musical sound is generated by using the waveform data held in a cache memory 11. When a cache miss of waveform data whose sounding is indicated is detected, the waveform data regarding the sounding indication are read out of a waveform memory 10 and transferred to the cache memory 11 and the waveform data having been transferred are used to generate a musical sound. Further, when timbre switching is indicated, whether waveform data used preferentially for a switching-indicated timbre are held or not in the cache memory 11 is detected and when the waveform data are not held in the cache memory 11, the waveform data are read out of the waveform memory 10 and transferred to the cache memory 11. <P>COPYRIGHT: (C)2004,JPO |
