Abstract
Multipliers respectively multiply a tone signal supplied from a sound source and a tone signal corrected by a filter according to hearing correction characteristics by balance control coefficients generated by a control coefficient generator based on tone volume control data, and an adder adds the products to adjust the tone volume balance. A multiplier multiplies the tone signal output from that adder by a tone volume control coefficient generated by the control coefficient generator based on the tone volume control data to adjust the tone volume. Frequency characteristics for correcting hearing characteristics are given to the tone signal in accordance with the tone volume of tones to be generated, thus maintaining tone volume balance upon hearing among tone colors of tones to be generated by an electronic musical instrument.
