A first mode (one-knob off mode) and a second mode (one-knob on mode) are provided as modes for setting parameters. In the first mode, individual elements corresponding to respective parameters of a parameter set are displayed in an operable state, allowing setting of individual parameters. In the second mode, the individual elements are displayed in a non-operable state, and one-element is displayed in an operable state, and a plurality of parameters of the parameter set are controlled by operating the one-element. At the time of switching from the first mode to the second mode, the parameter set is initialized.

Method and apparatus for setting values of parameters

An actuator includes: an electrostatic actuation mechanism including a stationary electrode and a movable electrode; a first movable part driven by the electrostatic actuation mechanism; a first elastic support part that elastically supports the first movable part; an electret formed in at least one of the stationary electrode and the movable electrode; and a drive control unit that controls application of voltage to the electrostatic actuation mechanism. In the actuator a plurality of stable states are set in which the first movable part is positioned at a stable position at which an electrostatic force generated by the electret matches with an elastic force exerted by the first elastic support part or at a stable position near such stable position. By applying a voltage to the electrostatic actuation mechanism, the first movable part may be displaced from any stable position to another stable position.

Performance data is generated by performing in real time a music piece starting at a desired performance position. Performance position, in the music piece, of the real-time performance data is estimated from reference performance data of the music piece. Performance data to be performed following the estimated position is identified, and accuracy of the estimated position is determined in accordance with whether performance data corresponding to the identified performance data is generated as next real-time performance data. Because the accuracy of the estimated position is determined after generation of the next real-time performance data, a performance position following the estimated position determined as accurate represents a current performance position. Score based on the reference performance data is shown on a display, and the current performance position in the real-time performance is indicated on the displayed score. The indication of the current performance position on the display is moved in accordance with the identified tempo.
