Abstract
A pitch bend apparatus for electronic musical instrument having a voltage-controlled oscillator that works as a tone generator is provided with a first variable resistor for operating the pitch bend as well as a second variable resistor for setting a varying width of pitch bend or a maximum amount of pitch deviation. The varying width of the pitch bend is controlled by connecting the first and second variable resistors into an amplifier circuit to control the gain thereof, or by controlling the voltage applied to the first variable resistor by means of the second variable resistor.
