Abstract
A musical tone generation apparatus is provided with a plurality of tone generation channels, a first memory for storing musical tone parameter including tone color specifying parameter, i.e., tone color name or number of tone color, in units of the tone generation channels, and a second memory for storing tone color parameter data. When tone color change is designated, the first parameter memory outputs tone color specifying parameter to the second parameter memory. In response to this, the second memory outputs the changed tone color parameter data to the tone generation channels to thereby generate tone having new tone color. As a result, tone color change is easily performed.
