Abstract

PURPOSE: To control the variable width of the pitch bend of the electronic musical instrument through simple operation with good reproducibility by controlling the varlable width of gain by connecting the other variable resistance to the other input terminal of an operational amplifier whose gain is regulated by a variable resistor.
CONSTITUTION: The operational amplifier OP1 of a pitch bend device 50 which applies a reference voltage to a pitch voltage generating circuit corresponding to touched keys is regulated of its gain by a variable resistor 51 for reference voltage setting connecting to non-inversion input terminal. On the other hand, the non- inversion and inversion output terminals of said amplifier OP1 are connected to both ends P, Q of a variable resistor 52 for pitch bend operation symmetrical to the grounded neutral point M and the gain of the amplifier OP1 changes according to the product of the gain set by the resistors 51, 53. Hence, if the slider 53a of the resistor 53 is connected to both ends P, Q, the reference voltage symmetrically differing up and down, such as 1 octave or the like is outputted from the amplifier OP1, thus the variable width of the pitch bend is controlled with good reproducibility through simple operation
