A touch curve memorystores therein a touch curve formed by velocity values corresponding to touch data generated by a keyboard device. A correction coefficient generatorgenerates a correction coefficient composed of a ratio of one of the velocity values stored in the touch curve memory corresponding to one of the touch data generated by the keyboard device, in a maximum touch memory mode switched by a mode switch(SW), to a maximum value of the velocity values in the touch curve memory. A correctormultiplies the correction coefficient generated by the correction coefficient generator by the respective velocity values stored in the touch curve memory, and then generates a touch curve formed by new velocity values. Accordingly, it is possible to provide a touch control apparatus and a touch control method which can obtain a touch curve, from which a touch response suitable for a user can be obtained, easily and in a short time.

Touch control apparatus and touch control method that can be applied to electronic instrument

An automatic performing apparatus and an electronic instrument with which a user can carry out an automatic musical performance, even for a complicated arrangement, simply by providing external events at certain intervals or corresponding only to a melody. In such an electronic instrument, at the time of execution of the automatic musical performance, the keyboard events are provided at intervals of one beat. Then, the automatic musical performance is progressed within a certain section corresponding to each of the provided keyboard events. Otherwise, at the time of execution of the automatic musical performance, the keyboard events are provided at the timing of a melody. Then, musical tones for the corresponding melody are generated, while those for accompaniments following the melody are also automatically generated. Furthermore, the tempo of the automatic musical performance is set on the basis of intervals between the keyboard events.
