Abstract

A tone setting device includes an operating section for selecting segments in combination from among various segments of exciting mechanisms and structures employed in plural types of musical instruments, and a data supply section supplies tone setting data, corresponding to the combination of the selected segments, as data for setting a characteristic of a tone. By thus combining segments of desired musical instruments, a free tone selection can be conducted easily in such a form where the selected tone color can be readily recognized by a human operator. Also, a plurality of parameters are allocated to a single operator so that the parameters can be simultaneously adjusted by respective unique amounts of change based on operation of the same operator.
