US 6,548,749 B2 · Electronic musical instrument and tone volume control method

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.

Dependent claims

An electronic musical instrument for generating a tone on the basis of a tone signal, comprising:

a filter having hearing correction characteristics for correcting the tone signal, wherein the hearing correction characteristics provide same tone volume balance and tone colors of tones upon hearing, as those tones generated at a large tone volume upon generating tones on basis of tone signals at a minimum tone volume that the electronic musical instrument can generate;
and
a mixing unit for mixing a received tone signal and the tone signal corrected by the filter, at a given ratio on basis of tone volume control information used to control a tone volume of the tone to be generated, and outputting the mixed signal.
