摘要:
When performance information, such as MIDI data, is input, physical events or phenomena are simulated on the basis of the input performance information, and computer graphics or CG parameters and tone parameters are determined on the basis of the simulated results. The determined CG parameters are passed to a general-purpose CG library, while the determined tone parameters are passed to a tone generator driver. The general-purpose CG library generates data representing a three-dimensional configuration of an object on the basis of the received CG parameters, and executes a rendering operation to generate two-dimensional picture data on the basis of the three-dimensional data, so that the thus-generated two-dimensional picture data is visually displayed. The tone generator driver generates a tone signal on the basis of the received tone parameters, which is audibly reproduced as an output tone. By thus controlling the tone and picture collectively, it is possible to accurately simulate a performance on a musical instrument on the real-time basis.

There is provided a database storing motion components, each of which includes motion information representative of a performance motion trajectory corresponding to a subdivided performance pattern for each musical instrument or part along with sounded point markers specifying tone-generation timing in the motion information. Motion components corresponding to the performance information are sequentially read out from the database to create basic motion information, and a three-dimensional picture is generated on the basis of the basic motion information and visually shown on a graphic display unit. Picture to be thus displayed can be selected optionally via a musical instrument change switch, player change switch and stage change switch, and the selected picture can be displayed in any desired direction by means of a viewpoint change switch.

Image information representing a manner of playing a piece of music can be diplayed while playing the piece of music. Performance image information is created, which enables displaying an image showing a manner of playing a piece of music while playing the piece of music. A motion component database is created, which comprises a plurality of motion components each created for each musical instrument or each part and stores a trajectory of a fraction of motion of a player and a musical instrument in one of at least one performance method being typical of the each musical instrument or the each part. Motion descriptive information is created, which designates one of the motion components corresponding to performance information on the piece of music to be played and a designated one of the at least one performance method, on a time schedule determined by a predetermined musical time unit of the piece of music to be played. Sequence information is created, which comprises the motion descriptive information, and the performance information. The designated one of the motion components can be edited, and the edited motion component is stored in the motion component database.

A method of generating musical tones and a storage medium storing a program for executing the method are provided. Musical piece data is decomposed into phrases, the musical piece data being formed of pieces of performance data arranged in the order of performance. The pieces of performance data of the musical piece data are analyzed for each of the phrases obtained by the decomposing step. Tone color control data is prepared for each of the phrases according to results of the analyzing. The pieces of performance data of the musical piece data are reproduced by sequentially reading the pieces of performance data at timing at which the pieces of performance data are to be performed to the order of performance. Tone color characteristics of musical tones to be generated based on selected ones of the pieces of performance data which are reproduced by the reproducing step, are controlled according to the tone color control data prepared for ones of the phrases to which the selected ones of the pieces of performance data belong, respectively.
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.

A sound source apparatus has operation blocks composed of softwares used to compute waveforms for generating a plurality of musical tones through a plurality of channels according to performance information. In the apparatus, a setting device sets an algorithm which determines a system composed of selective ones of the operation blocks systematically combined with each other to compute a waveform specific to one of the musical tones. A designating device responds to the performance information for designating one of the channels to be used for generating the musical tone. A generating device allocates the selective operation blocks to the one channel and systematically executes the allocated selective operation blocks according to the algorithm so as to compute the waveform to thereby generate the musical tone through the channel. The generating device responds to a variable sampling frequency for executing the operation blocks to successively compute samples of the waveform in synchronization to the variable sampling frequency so as to generate the musical tone, and sets the variable sampling frequency according to process of computation of the waveform by the operation blocks.
