ABSTRACT:
A tone color control apparatus for a musical tone signal producer has a first memory and a second memory. The first memory memorizes plural sets of tone color data for control of each tone color of plural different musical tone signals produced at the musical tone signal producer. The second memory memorizes plural sets of index data for indexing the plural sets of tone color data and also memorizes plural sets of modification data respectively corresponding with each set of index data. A desired set of the memorized index data and the corresponding set of the modification data are simultaneously read out from the second memory under control of tone color selection by a player. The tone color data are also read out from the first memory under control of the read out index data. The read out tone color data are modified based on the read out modification data to be applied to the musical tone signal producer for controlling a tone color of a musical tone signal produced therefrom.
