ABSTRACT:
Musical tones are produced according to song data basically by three steps. The first step converts the song data sequentially into control parameters. The control parameters are written into a parameter memory. Then, the second step generates waveform data by using the control parameters written in the parameter memory. The generated waveform data are written into a waveform memory, while the used control parameters are erased from the parameter memory to provide a vacant area. Lastly, the third step reads the waveform data sequentially from the waveform memory to produce the musical tones. Characterizingly, the second step of generating waveform data is executed dependently on progression of the third step of reading the waveform data. Further, the first step of converting the song data is executed independently from progression of the second step of generating waveform data as long as the parameter memory has the vacant area sufficient to store the control parameters converted from the song data.
