Abstract: A music sound generator imitates released key string vibration sounds (RKSV) and cabinet resonances of an acoustic piano. When a key is pressed, waveform is readout from a normal music sound waveform memory 15. The normal sound waveform is inputted into a filter 21, and inputted into a filter 22 through a band-pass filter 33. Output waveform of a cabinet resonance waveform memory 17 is inputted into a filter 23 when the key is pressed. Outputs of the filters are synthesized by an adder 27 through multipliers 24 through 26. When the key is pressed, a cut-off frequency of the filter 22 is sufficiently low and RKSV is not generated. If the damper is not on when key-releasing, the cut-off frequency is returned to normal and RKSV is generated. A level controller 32 attenuates the RKSV and the cabinet resonance for a longer time than the normal music sound.

Abstract: Embodiments of the keyboard system that can determine accurate key operation. The system provides immediate processing of the data input streams from various strike sources, the key stroke depth data, the key strike speed data, the key strike acceleration data. The movement state volume V can be calculated using a formula shown below, based on the key strike depth D, the key speed S, the key acceleration A, the coefficient a, b, c, and constant d. V=a*D+b*S+c*A+d. When the volume level exceeds the predetermined level A, the system determines that the key has been pressed. When it is determined that the key has been pressed, the “note-on” information is outputted to the sound source. The velocity value included in the “note-on” information is calculated with reference to the velocity curve based on the key speed when it is determined that the key has been pressed.
