Abstract
A tone control apparatus for use in an electronic musical instrument is responsive to an easily accessible switch such as a foot-lever switch to control conditions of muscial tone which include, for example, a tone pitch, a tone color, a tone volume and a tone effect. The tone control apparatus has a keyboard for designating a frequency of a musical tone to be generated and a musical tone generating circuit for generating a musical tone having a frequency designated by the keyboard. The tone control apparatus further has a memory for storing a plurality of groups of tone control data. Each time the foot-lever switch is operated by the performer, one of the tone control data group is read and supplied to the musical tone generating circuit to control the conditions of the generating musical tone. In a first mode, the plurality of tone control data groups are sequentially read in synchronization with the operations of the foot-lever switch. In a second mode, the tone control group designated by a group number, which has been preset by the operator, is read. Thus, the performer can change the conditions of the generating musical tone by operating the foot-lever switch with his foot even when performing music on the keyboard with his both hands.
