PURPOSE:To reflect the feeling of a player to a musical sound to allow various musical sound controls, compared with a conventional operation only by the fingers by providing such a constitution that a plurality of musical sound control signals can be outputted by pressing an operating part by the palm or finger of the player. CONSTITUTION:The operation part 2 of a controller 1 is covered with an elastic film 5, and a player can increase and decrease the volume in a fluid chamber 6 by operating this part by his palm or finger. The fluid in the fluid chamber 6 flows out and/or flows in through a fluid passage 23 by the increase and decrease of the volume. The fluid passage 23 has a pressure sensor 22. When the fluid flows out and/or flows in, a positive/negative pressure is caused on the pressure sensor 22, and this is detected by the pressure sensor 22. The output of the pressure sensor 22 is outputted as a musical expression by the palm of the player, and used as a musical sound control signal. Since the fluid chamber 6 is plurally provided, a plurality of outputs sensitive to the inclination of the palm or the movement of the finger are obtained, allowing a delicate musical expression. |
