Abstract
A musical-tone-signal-generating apparatus which determines the current tone-color-designation state on the basis of the operation of one or more tone-color-selection switches, reads from a memory tone-color-control information that specifies the tone colors corresponding to the current tone-color-designation state, and controls the generation of musical-tone signals on the basis of the tone-color-control information. The tone-color-control information includes various data necessary for generating one or more tone colors selected by the tone-color-selection switches. Thus, the apparatus can generate a plurality of tone colors simultaneously with a simple configuration.
