PROBLEM TO BE SOLVED: To sensuously perform the gain regulation of each string detected by 6-string pickup. SOLUTION: The signal waveform of each string detected by 6-string pickup is time-divided and converted into a digital signal in an A/D converter 2, and inputted to a gain regulating means 3. When the same string of a guitar is touched with the same pitch name and the same strength, a control means 7 regulates the gain of the gain regulating means 3 corresponding to this string according to the velocity of the touched string. Since the play information of MIDI is outputted to a sound source part 9 from the control part 7 to generate a musical sound, and it is generated from a speaker 10, the gain can be sensuously regulated while listening to the sound volume from the speaker 10. |
