Abstract
A music performing apparatus comprises a manipulative music performing device which performs music according to the player's musical performance on the apparatus and an automatic accompaniment performing device which performs musical accompaniment according to automatic accompaniment signals provided in the apparatus. The properties and the manners of a musical performance and an automatic accompaniment are determined by the parameters set by the various controls such as switches and knobs in the control panel provided on the apparatus. A state of combination of such parameters is defined as a registration for a musical performance. Different registrations are stored in a data storage device representing different combinations of the parameters, and a desired one of the registrations is selectively called by the user to set the performance properties and manners. During the time the automatic accompaniment is running, when some registration is selected and the selected registration includes parameters related to the automatic accompaniment, such accompaniment-related parameters shall be excluded in setting the performance properties and manners, while the rest of the parameters are used to control the properties and manners of musical performance other than the automatic accompaniment part. Thus, inadvertent and unwilling changes in the automatic accompaniment can be avoided.
