摘要：
A music playback device applicable to a portable telephone terminal device uses a sequence data FIFO memory and a waveform data FIFO memory both having limited storage capacities. A system CPU performs successive transfer of sequence data and waveform data in response to shortage events of the memories. Hence, it is possible to actualize high-quality playback of musical tunes with small storage capacities of the memories and with small load of processing of the system CPU.
