Abstract
A musical tone synthesizing apparatus utilizes digital signal processors (DSPs) to realize synthesis of musical-tone waveforms with regard to a variety of tone colors. The apparatus stores microprograms and tone-color parameters in advance. Herein, the microprograms represent musical-tone-synthesis algorithms each synthesizing musical tones of a specific tone color. The tone-color parameters contain common parameters and selective parameters to provide a compatibility between different systems having different scales in hardware and software. The common parameters are commonly shared by the different systems, while the selective parameters are provided for a selective use of the musical-tone-synthesis algorithms. So, the apparatus responds to a selection of the musical-tone-synthesis algorithms, wherein the apparatus executes the selected musical-tone-synthesis algorithm, using the common parameters and at least one of the selective parameters, to synthesize musical-tone waveforms with regard to a desired tone color. Incidentally, it is possible to provide different algorithms with regard to derivative tone colors which derive from a base tone color.
