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: Based on the understanding that time-varying characteristics of a tone element, such as an amplitude and pitch, in waveform data acquired through a live performance of a musical instrument include a variation component intended or controllable by a human player and a variation component not intended or non-controllable by the human player, the present invention allows the two components to be adjusted/controlled separately and independently of each other, so as to achieve effective and high-quality control. Discrete variation value train is acquired for at least one particular tone element in original waveform data, and the acquired variation value train is separated, in accordance with a time constant factor, into a “swell” value train of a relatively great time constant and a “fluctuation” value train of a relatively small time constant. The “swell” value train and “fluctuation” value train are variably controlled independently of each other.

The filter circuit performs filter processing for the musical sound signal, based on the filter characteristics determined by the set of filter coefficients.

When performance data for the ordinary-type tone generator are acquired in a case where the special-type tone generator can be used, presence of a predetermined rendition style is detected on the basis of various control data included in the performance data, the control data in a portion of the performance data, corresponding to the predetermined rendition style, is converted into simple data that does not represent the predetermined rendition style, and also rendition-style designating data specifying the predetermined rendition style is added. In this way, the acquired performance data are reformed into performance data for the special-type tone generator.

Abstract: A method of simulating a string using a wave equation relates movement of the string in time to force acting on the string, wherein the force acting on the string simulates a stream of a fluid medium flowing relative to the string. The simulated string is supported between two supports and is aligned at rest in a first direction between the two supports, a first of which allows movement in a second direction orthogonal to the first direction and a second of which does not allow movement. The string is then caused from rest to vibrate in a plane, which includes the first and second directions, by turbulence in the fluid flow causing the stream of fluid medium to exert a pressure on the string in the second direction. Movement of the string out of alignment with the first direction causes the stream of fluid medium flowing in the first direction to exert a force on the string in the second direction.
