PURPOSE:To reflect emotional representation on a played musical sound by generating initial-touch data and after-touch data according to a signal generated by an all-stroke sensing means. CONSTITUTION:A key operation panel detecting circuit 100, a key depression detecting circuit 110, a key depression end detecting circuit 120, and a touch data generating circuit 130 constitute a detecting means which detects the speed or acceleration of an operation element as a digital signal according to the pulse signal generated by the all-stroke sensing means, and they are provided corresponding to the respective keys of a keyboard. Then the key operation pulse detecting circuit 100 detects a pulse signal generated by a pulse generation part PG provided to each key and forms a waveform. Namely, the initial-touch data and after-touch data are generated according to the signal generated by the all-stroke sensing means. Consequently, various musical sound control parameters corresponding to the respective data are varied and controlled to enable a player to represent his or her feeling with full of emotion. |
