Abstract: In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to an excitation unit provided on a soundboard. In response to a mechanical vibration generated by the excitation unit, the soundboard is vibrated so as to generate an acoustic vibration sound corresponding to the operated key. The excitation unit is supported by a supporting unit such that less or no load of the excitation unit except a vibration member vibrated in response to the drive signal is applied to the soundboard. Thus, only a load of the vibration member which is a very light portion of the excitation unit is applied to the soundboard, thereby vibration characteristics of the soundboard being hardly affected. When a sound damping mode is selected, a stopper is permitted to prevent a hammer from striking a sounding body.

Abstract: An acoustic effect impartment apparatus detects striking of any one of strings by a corresponding hammer in an acoustic piano like a grand piano, and vibrates a vibration section with a driving waveform signal obtained by synthesizing sine wave signals of the fundamental frequency and harmonic frequency of the hammer-struck string. Such vibration of the vibration section is transmitted to the keys via a soundboard and bridge of the piano. Thus, vibration is excited in the hammer-struck string by the striking with the hammer but also by the driving waveform signal, so that an acoustic effect corresponding to the driving waveform signal is imparted. Because the driving waveform signal is a simple signal using the sine wave signals corresponding to the fundamental frequency of the string, a natural feeling of the acoustic piano will not be lost even when the acoustic effect is imparted.

Abstract: Processor-implemented methods and systems for polyphonic note detection are disclosed. The method includes converting a portion of a polyphonic audio signal from a time domain to a frequency domain. The method includes detecting a fundamental frequency peak in the frequency domain. The method then detects a defined number of integer-interval harmonic partials. If a defined number of integer-interval harmonic partials relative to the fundamental frequency peak are detected the fundamental frequency is recorded as a detected note. This process is repeated for each fundamental frequency until each note in the polyphonic audio signal has been detected. For example, this method allows detection of each note in a strummed guitar chord to provide feedback on the tuning of each string in a strummed chord or allows detection and feedback of the timing and pitch errors for guitar chords played along with a reference track.
