Resonance sound signal generation device, resonance sound signal generation method, non-transitory computer readable medium storing resonance sound signal generation program and electronic musical apparatus

Abstract

A resonance sound signal generation device comprises a designation receiver that receives designation of a pitch, a sound signal instructor that provides an instruction for generating a sound signal corresponding to the designated pitch, a producer that produces a resonance sound signal representing a resonance sound based on a plurality of pitches, a determiner that determines whether another pitch is designated at a time of designation of one pitch, and a resonance sound instructor that instructs the producer to produce a resonance sound signal of the one pitch and a resonance sound signal of the another pitch based on the one pitch and the another pitch when determination is made that the another pitch is designated at the time of designation of the one pitch, and does not instruct the producer to produce resonance sound signals when determination is made that the another pitch is not designated at the time of designation of the one pitch.
