PURPOSE:To surely read out waveform data before sound emission time by providing a music producing means which produces music in accordance with waveform data preset to a waveform data buffer when the counted time of a present time counting means reaches the sound emission time. CONSTITUTION:Music producing means CH0-CHN are provided which produce music in accordance with waveform data preset to the waveform data buffer when the counted time of a present time counting means 13a reaches the sound emission time. Waveform data is transferred to the waveform data buffer in accordance with the counted time of a sequence time counting means 13b which counts the time earlier than that of the time counting means 13a, and music is produced in accordance with the counted time of the present time counting means 13a. Music producing means CH0-CHN do not directly access waveform data in a disk type storage medium but produce music in accordance with data in the waveform data buffer. Thus, waveform data is surely read out before the sound emission time and the device is made simple and inexpensive. |
