摘要： Tone synthesis apparatus synthesizes a tone of a wind instrument generated in response to vibration of a reed contacting a lip during a performance of the wind instrument. First arithmetic operation section solves a motion equation representative of behavior of the reed in an equilibrium state with external force acting on the lip and a second motion equation representative of behavior of the lip in the equilibrium state, to thereby calculate displacement yb(x), y0(x) of the lip and reed in the equilibrium state. Second arithmetic operation section solves a motion equation of coupled vibration of the lip and reed with calculation results of the first arithmetic operation section used as initial values of the displacement yb(x), y0(x) of the lip and reed, to thereby calculate the displacement y(x, t) of the reed. Tone is synthesized on the basis of the displacement y(x, t) calculated by the second arithmetic operation section.

摘要： Flow velocity sensor and a length sensor are provided on or near an edge of the lip plate which the air jet from the embouchure hole impinges against. Jet flow velocity Ue at the edge and a jet-blowout-outlet-to-edge distance d are detected by the sensors. Jet transfer time τe is calculated by an equation of τe=d/Ue, and a jet traveling angle θe′ is calculated by an equation of θe′=2πfso1×τe (where fso1 represents a frequency of a tone to be generated). When θe′ has decreased to π/2 during tone generation in a primary mode, the mode changes to a secondary mode to raise the pitch of the currently generated tone by one octave. When θe′ has increased to 3π/4 during tone generation in the secondary mode, the mode changes to the primary mode to lower the pitch of the currently generated tone by one octave.

摘要： A tuner apparatus 10 causes a user to designate a musical instrument that is to be tuned and a reference pitch that is a standard upon tuning, by a process at a setting portion 110. A pitch detecting portion 130 detects a pitch of a performed note inputted via a microphone 20 and input portion 120. A target note specifying portion 140 defines a note name, which is positioned nearest to the performed note in a predetermined temperament (e.g., 12-note equal temperament), as a target note based upon the detected pitch of the performed note and the inputted reference pitch. Then, a calculating portion 150 calculates a difference between the pitch of the performed note and the pitch of the target note, and a display control portion 160 causes the display device 30 to display the calculated difference. Further, the display control portion 160 converts the target note into a note name written in a score relating to the musical instrument to be tuned by using a transposition parameter relating to the musical instrument to be tuned that is stored in the storage portion 100 and set by the setting portion 110, and causes the display device 30 to display a staff in which a note corresponding to the note name written in a score is written.

摘要： Set of sample identification information and representative-point designating data is generated in accordance with performance data or the like, and sample data is obtained by referring to a database in accordance with the generated sample identification information. If necessary, the thus-obtained sample data is adjusted or modified on the basis of the representative-point designating data. Characteristic of the sample data can be controlled appropriately and efficiently by the representative-point designating data specifying representative sample points for which sample data adjustment is to be performed. For example, particular sample data that is located at a given representative sample point designated by the representative-point designating data is adjusted in accordance with adjustment information, and other sample data that is located at another sample point is adjusted simultaneously with such adjustment at the representative sample point.

摘要： A music apparatus uses a processing unit of a universal type having an extended instruction set used to carry out parallel computation steps in response to a single instruction which is successively issued when executing a program. A software module defines a plurality of channels and is composed of a synthesis program executed by the processing unit using the extended instruction set so as to carry out synthesis of waveforms of musical tones through the plurality of the channels. The plurality of the channels are optimally grouped into parallel sets each containing at least two channels. The synthesis of the waveforms of at least two channels belonging to each parallel set are carried out concurrently by the parallel computation steps. A buffer has a capacity sufficient to store the waveform samples allotted to one frame period. A cache has a capacity sufficient to store a subset of the waveform samples which is an integer division of the set allotted to one frame period. The synthesis program is executed by the processing unit at one frame period so as to carry out synthesis of a set of waveform samples allotted to one frame period while efficiently accessing the cache. Any designated subroutine programs are sequentially called in response to call instructions to process the waveform samples during the synthesis.

摘要： In an instrument performance learning apparatus, a storage section stores model performance waveform data representing a time series of individual performance sounds of a model performance. An input section inputs real performance waveform data representing a time series of individual performance sounds of a real performance. A pitch graph display control section detects each pitch of each individual performance sound from the stored model performance waveform data and from the inputted real performance waveform data, and displays a pitch graph representing transitions of the detected pitches. An amplitude envelope graph display control section detects each amplitude level of each individual performance sound from the model performance waveform data and from the real performance waveform data, and displays an amplitude envelope graph representing transitions of the detected amplitude levels, such that the amplitude envelope graph has a time axis common to that of the pitch graph while the amplitude envelope graph is located in an area of the display device which does not overlap with another area of the display device where the pitch graph is located.

摘要： A waveform producing method includes a step of producing a waveform presenting style-of-rendition characteristics corresponding to style-of-rendition identification information, on the basis of individual vector data arranged on the time axis. Each style-of-rendition identification information is representative of style-of-rendition characteristics of a performance tone and indicates one of a plurality of styles of rendition to which the style-of-rendition characteristics correspond. A plurality of vector data are generated, in accordance with the received style-of-rendition identification information, for production of a waveform presenting the style-of-rendition characteristics. The vector data correspond to a plurality of different fundamental waveform factors for constituting a waveform. By arranging the individual vector data on the time axis, a waveform shape or envelope corresponding to the waveform factors can be built along a reproducing time axis of the performance tone. Thus, there can be produced a performance tone waveform presenting the style-of-rendition characteristics corresponding to the style-of-rendition identification information.

摘要： An acoustic wind instrument having a conical tube is simulated by two cylindrical tubes communicated to each other at each one end. A parallel connection of electrical signal transmission lines, each simulating a cylindrical tube constitute a synthesizer synthesizing the sound of the conical acoustic wind instrument. Each signal transmission line includes a shift register for giving a delay to the input signal, a multiplier for simulating sound reflection, and a filter for affording a tone color. An exciting signal is injected at the interconnection of the parallel connection through a junction circuit.

摘要： The musical tone synthesizing apparatus synthesizes a musical tone signal in response to the wind instrument and the like to thereby simulate a resonance tube providing with several sound holes each opened or closed by each finger of a performer. Herein, the input signal is delayed by the predetermined delay time, and then the predetermined operational process corresponding to the signal-scattering operation is carried out on the delayed signal. The coefficient used in this operational process is varied in response to the open/close state of each sound hole. Thus, the operation result can simulate the musical tone to be sounded from the resonance tube of the wind instrument and the like.
