Abstract
A musical-tone-generating-control apparatus including a number of musical-tone-signal-generating channels, each of which generates musical-tone signals having tone pitches designated by tone-pitch information and having tone colors determined by tone-color information. These tone-pitch information and tone-color information are supplied to a musical-tone-signal-generating channel selected by predetermined rules. One of the rules is that a newly entered key-code is assigned to a musical-tone-signal-generating channel which has been generating a musical-tone signal whose tone color is the same as that of the newly entered key-code. Thus tone-color-control parameters need not be transferred to the channel, and this saves time necessary for the transfer, resulting in a speeding up of processing. Other similar rules are also used resulting in similar advantages.
