PURPOSE:To facilitate gentle fast performance and quick trill performance by setting an optional point in the movement range of key operation as the start point of the key operation and controlling musical sound control parameters in real time with the signal from a touch sensor in a specific time from the start point. CONSTITUTION:The musical sound control parameters are controlled in real time with touch data detected by a touch data detecting means 130 which detects as a digital value the signal from the touch sensor in the specific time from the start point set in operation start point setting means VR1 and 115 where an optional point in the movement range of the key operation can be set as the start point of the key operation. Consequently, the start point of the key operation is set to the initial point of the key depression and then even when the operation stroke of a key is much smaller than the whole stroke, sound volume and sound generation timing are controlled as the musical sound control parameters to easily carry out the gentle fast performance and quick trill performance. |
