Abstract
A sound producing apparatus which implements a sound output process based on waveform data, corresponding to sound generated by the apparatus, and system-sequence data including information for processing the waveform data. The apparatus comprises a read-write main memory for storing the waveform data and system-sequence data of a selected music title. Also included is a first submemory for storing the waveform data, and a second submemory for storing the system-sequence data. A sound signal generator generates sound signals based on the waveform data and the system-sequence data stored in submemories. A controller controls the entry of waveform data and system-sequence data of a selected music title, stored in the main memory, into the first and the second submemories, respectively. The controller also controls the sound signal generator based on the system-sequence data stored in the second submemory. A communication controller controls the entry of waveform data and system-sequence data, received from a host unit over a telecommunication line, into the main memory.
