Abstract: Partial waveform data representative of a waveform shape variation are extracted from supplied waveform data, and the extracted partial waveform data are stored along with time position information indicative of their respective time positions. In reproduction, the partial waveform data and time position information are read out, then the partial waveform data are arranged on the time axis in accordance with the time position information, and a waveform is produced on the basis of the waveform data arranged on the time axis. In another implementation, sets of sample identification information and time position information are obtained in accordance with a performance tone waveform to be reproduced, and sample data are obtained from a database in accordance with the sample identification information. The thus-obtained sample data are arranged on the time axis in accordance with the time position information, and the desired waveform is produced on the basis of the sample data arranged on the time axis. The time position information and/or sample data may be adjusted in accordance with predetermined adjustment information.

Abstract: 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.

Abstract: Tone color data are stored in a tone generator storage region of a RAM. The tone generator data storage region is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region, and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region, a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region, the tone color data are read out from a storage medium storing the selected tone color data, and transferred to and stored in the tone generator data storage region, while generating a musical tone based on other tone color data similar to the selected tone color data.

Abstract: Sets of waveform data of unit waveforms stored in a memory each include first and second loop waveform segments at both ends of a non-loop waveform segment and any one of the unit waveform data sets can be selectively readout from the memory. The waveform data set of a desired one of the unit waveforms is read out from the memory and is connected with another waveform preceding or following the read-out unit waveform using the first or second loop waveform segment in the read-out unit waveform. Thus, a smooth connection between the read-out unit waveform and the other waveform is achieved with ease. This is because the loop waveform can be smoothly connected with any other waveform through cross-fade synthesis or phase-matched connection technique performed at an appropriate point in the loop. With such arrangements, when a tone waveform is to be formed by reading out the loop waveform from the memory, it is possible to execute good-quality waveform formation rich in controllability and editability, taking articulation (style of rendition) of a sound into account, in a manner rich in controllability and editability.

Abstract: The number of waveform samples per unit time, i.e., waveform sample forming resolution is variably set depending on characteristics of a tone to be generated, such as construction of harmonic components in the tone. The number of waveform samples per unit time is increased for a tone or portion (e.g., attack portion) of a tone containing a relatively great number high-order harmonic components. Conversely, for a tone or portion (e.g., sustain portion) of a tone containing fewer high-order harmonic components, the number of waveform samples per unit time is decreased. By thus variably setting the waveform sample resolution, a process for arithmetically forming waveform sample data can be performed efficiently without involving significant waste. In cases where a plurality of tone generating channels are provided, the waveform sample forming resolution may be variably set independently for each of the channels. Also, in applications where the waveform sample data are to be stored in a waveform memory, effective data compression can be achieved by storing the waveform data with the waveform sample forming resolution variably set for each of different waveform segments.

Abstract: A method of generating musical tones is provided. Data indicative of waveforms including at least a first predetermined waveform and a second predetermined waveform are stored in a first storage device such as a RAM. Data indicative of the first predetermined waveform and the second predetermined waveform are sequentially read from the first storage device, in response to a tone-generating command. The data indicative of the first predetermined waveform is read from the first storage device and stored in a second storage device, such as a cache memory, which is operable at a higher speed than the first storage device. The data indicative of the first predetermined waveform stored in the second storage device is repeatedly read from the second storage device, following the reading of the data indicative of the first predetermined waveform from the first storage device. Musical tones are generated based on the data read out by the first and second reading steps. Typically, the first predetermined waveform and the second predetermined waveform are a loop waveform and an attack waveform, respectively.

Abstract: A circuit for adding a resonance tone to a tone signal to be generated is provided. When a damper operator is not operated, the resonance tone is not added but an ordinary tone signal is generated. When the damper operator has been operated, the resonance tone is added so that a tone signal including the resonance tone is generated. An effect of a damper operator, i.e., loud pedal, in a piano, a natural musical instrument, is thereby simulated with high fidelity. The resonance tone may be produced by passing an ordinary tone signal through a filter. Alternatively, data obtained by sampling an actually produced tone of a piano, a natural musical instrument, when a damper operator, i.e., loud pedal, is ON may be stored in a memory and a resonance tone may be generated by reading out the stored data from the memory. The signal of the generated resonance tone may be sounded by itself or after mixing with an ordinary tone signal at a suitable mixing ratio. In addition to the imparting of the resonance tone, a known control for switching of a decay rate of a tone volume envelope may be performed.
