PURPOSE:To obtain an actual feeling of performance by providing an air passage limiter which opens and closes a passage of breathing from a mousepiece and a control means which controls the air passage limiter according to a generated musical sound. CONSTITUTION:When a player puts on a blow-in mouth 2 to blow air through a blow-in mouth 2, the pressure in the mousepiece rises with the blown-in air and a pressure sensor 4 detects this pressure variation and sends the variation to a pressure control means (CPU) 10, so that the data is used for musical sound control. Further, the air passage limiter 5 is driven with the control signal sent from a CPU 10 to protrude a shield plate 6 into the air passage by a distance corresponding to the contents of the control signal. Therefore, the resistance feeling of breathing that the player have varies. Consequently, the player feels as if a musical instrument were played actually. |
