PROBLEM TO BE SOLVED: To enhance the expression power of performance by artificially generating hammering sounds which occur when a pitch designation switch is depressed. SOLUTION: When a player depresses a string press switch of a pitch switch part, a musical sound signal of a corresponding pitch is generated from a musical sound signal generation part 2 and is outputted to one of digital amplifiers 9a to 9f of a corresponding channel. Meanwhile, a signal indicating a small sound volume is outputted from a small sound normalizing part. The amplitude of the musical sound signal is amplified with an amplification factor corresponding to the small sound volume by the digital amplifier to which the musical sound signal is outputted out of the digital amplifiers 9a to 9f to emit sounds through a DAC 10, an amplifier 11, and a speaker 12. That is, musical sounds of the corresponding pitch are generated with a small sound volume by depression of only the string press switch. |
