Tone generator, electronic instrument, and storage medium

An electronic instrument for generating and producing a tone based on tone information by mixing at least first to third tone component signals, characterized by comprising:

• waveform storage means for storing a first waveform signal in which the first and second tone components are synthesized, and a second waveform signal consisting of the third tone component;
• first tone component signal acquisition means for acquiring the first tone component signal by extracting said first tone component from the first waveform signal of said waveform storage means;
• second tone component signal acquisition means for acquiring the second tone component signal by extracting said second tone component from the first waveform signal of said waveform storage means;
• control means for executing operation by switching said first tone component signal acquisition means and said second tone component signal acquisition means on the basis of said tone information;
• and
• tone signal generation means for generating a tone signal based on said tone information by mixing, by the operation execution control in said control means, the first tone component signal obtained by said first tone component signal acquisition means or the second tone component signal obtained by said second tone component signal acquisition means, and the third tone component signal acquired from the second waveform signal of said waveform storage means.

A storage medium which computer-readably stores processing steps for generating and producing a tone based on tone information by mixing at least first to third tone component signals, characterized in that said processing steps include:

• the storage step of storing a first waveform signal in which the first and second tone components are synthesized, in a waveform memory together with a second waveform signal consisting of the third tone component;
• the tone component signal acquisition step of acquiring the first or second tone component signal from said first waveform signal by switching, on the basis of said tone information, an output destination of said first waveform signal of said waveform memory between a first filter system for cutting said second tone component from said first waveform signal, and a second filter system for cutting said first tone component from said second waveform signal;
• and
• the tone signal generation step of generating a tone signal based on said tone information by mixing the first or second tone component signal obtained by said tone component signal acquisition step, and the third tone component signal acquired from the second waveform signal of said waveform memory.
