Electronic wind instrument capable of diversified performance expression

Abstract

There are provided a plurality of keys for designating a pitch and a plurality of sensors for detecting operating states of the keys. Main pitch determination section identifies respective ON/OFF states of the keys on the basis of output values from the sensors to thereby determines a performed pitch. When the output value from the sensor, corresponding to a particular one of the keys determined to be in the ON or OFF state, presents a predetermined intermediate value, a subsidiary pitch determination section determines another pitch on the basis of predetermined assumptive ON/OFF states of the keys. The assumptive ON/OFF states are similar to the ON/OFF states of the keys identified by the main pitch determination section except that the ON or OFF state of the particular key is inverted to the OFF or ON state. Pitch-bend information designating an intermediate pitch between the other pitch and the pitch determined by the main pitch determination section is generated, such as by interpolation, on the basis of the sensor output presenting the predetermined intermediate value. On the basis of the sensor output corresponding to the predetermined turned-ON key, a tone control signal can be generated to execute after-touch control. Any one of functions allocated to a predetermined key, such as a high trill key, may be selectively used depending on a selected mode.
