PROBLEM TO BE SOLVED: To reduce processing loads in generating pseudo low tones by elec tronic musical instruments or the like. SOLUTION: The generator generates wave form data of ordinary tones 38 and wave form data of pseudo low tones 52 in advance, based on data 50 indicating the lowest frequency regeneratable by a speaker or the like and material wave form data 30. The wave form data of pseudo low tones 52 are generated by pitch or diapason lower than the lowest frequency and are reproduced with the wave form data of ordinary tones 38. |
