摘要:
A plurality of sets of waveform data and switchover position information indicative of, for each of the sets of waveform data, one or more possible switchover positions in the waveform data are prestored in memory, and one set of waveform data is reproduced in accordance with the passage of time. During reproduction of a first set of waveform data, a second set of waveform data is designated at given timing in response to a user's instruction. Control is performed such that the waveform data to be reproduced is switched from the first set of waveform data over to the second set of waveform data in response to waveform data reproduction timing arriving at one of the possible switchover positions indicated by the switchover position information corresponding to the second set of waveform data. Reproduction of the second set of waveform data is started at the switchover position corresponding to the reproduction timing.

A method of emulating a sound of an audio apparatus by using a sound emulation apparatus includes obtaining k past samples (where k is a natural number that is equal to or greater than 1) by delaying a current sample of an audio signal; applying a plurality of characteristic functions indicating an input/output relationship of the audio apparatus to the current sample and the k past samples, respectively; and adding the current sample and the k past samples, to which the plurality of characteristic functions have been applied, respectively, to generate an emulation sound of the audio apparatus.

A musical performance apparatus is provided with a tone generation circuit 15 and a sound system 16 for emitting musical tones of musical instruments and control tones corresponding to musical score data SD which controls a musical score display apparatus 20. The tone generation circuit 15 has a tone volume adjustment circuit 15a3 which changes tone volume of only the musical tones in accordance with player's instruction and maintains tone volume of the control tones at a certain tone volume. The tone generation circuit 15 also has a pan adjustment circuit 15a4 which localizes the control tones so that the control tones will be emitted only from a certain speaker. Furthermore, the musical performance apparatus is designed such that the control tones are formed only of frequency components included in a certain high frequency band. Furthermore, the tone volume of frequency components which are included in frequency components representative of the musical tones and are further included in the certain high frequency band is controlled to be lower than the tone volume of the control tones.

The musical performance apparatus has a ROM 17c which stores sample values obtained by sampling a plurality of tones corresponding to a plurality of digital signals each having a different bit pattern so that the sample values of waveforms of the tones will correspond to sampling periods. In the ROM 17c, the sample values are stored in association with addresses. The musical performance apparatus also has a computer portion 17 and a tone generation circuit 15 which select one or more tones from the plurality of tones in accordance with musical score data SD formed of a plurality of bits, read out waveform data indicative of the selected tones from the ROM 17c, and reproduce the selected tones. The plurality of tones are formed of frequency components included in a certain high frequency band.

A musical performance apparatus has a waveform memory WM in which sample values indicative of waveforms of a plurality of tones are stored so that the sampling periods correspond to addresses. The musical performance apparatus also has a tone generation circuit 15 which can repeatedly reproduce a section of the tone. A loop top address and loop end address corresponding to the top and end of the section of the first tone, respectively, are designated. When a reading address for reading the sample values of the first tone has reached a certain address, the tone generation circuit 15 changes the designated loop top address and the loop end address to addresses corresponding to the top and end of the section of the second tone so that the reproduction of the section of the second tone will start at a position which is situated in the section of the second tone and corresponds to the certain address.

For each of a plurality of performance parts, a database (221) stores therein a plurality of part performance data. The part performance data for each of the parts includes a sound generation pattern and tone data corresponding to the sound generation pattern. A query pattern indicative of a sound generation pattern to be made an object of search is input by a user. A search is made through the database for part performance data including a sound generation pattern matching the query pattern. In response to a user's operation, one part performance data is identified from among searched-out results from the database, and the sound generation pattern of the identified part performance data is instructed as a new query pattern (Sa8b). Then, a further search is made through the database for part performance data including a sound generation pattern matching the new query pattern. In accordance with a user's operation, one part performance data is identified from among searched-out results, and the identified part performance data is edited. The thus-edited data can be registered into the database as new part performance data.
