An automatic performance device includes a memory for storing automatic performance data (including accompaniment-related data) for a plurality of performance parts and automatic accompaniment data, performance and accompaniment sections for reading out the automatic performance data and automatic accompaniment data respectively to execute performance based on the respective read-out data, and a mute section for muting a performance for at least one of the performance parts of the automatic performance data when the accompaniment section executes the performance based on the automatic accompaniment data. The device may includes a style data storage section for storing automatic accompaniment pattern data for each of a plurality of performance styles, a performance data storage section for storing automatic performance data containing pattern designation information designating a performance style to be used, a first performance section for reading out the automatic performance data to execute a performance based on the read-out data, a conversion section for converting the read-out pattern designation information into other pattern designation information, and a second performance section for reading out the accompaniment pattern data in accordance with the other pattern designation information so as to execute a performance based on the read-out data.

Character data representative of characters of song data and style data are written in header portions of the song data and the style data. When the user selects the song data and the style data, these character data are read out and compared with each other. By the comparison, a correction algorithm for correcting either the song data or the style data is determined. Either the song data or the style data is modified to match the other based upon the correction algorithm, and both data are simultaneously performed in an automatic performance.

A music data processing system having: a storage unit for storing performance data and text data or auxiliary data in a first storage format or in a second storage format; a first data search unit for searching the text data or auxiliary data stored in the first storage unit; a second data search unit for searching the text data or auxiliary data stored in the second storage unit; and a processing unit for processing text data or auxiliary data if the text data or auxiliary data of the first storage format can be searched by said first data search unit, and if the text data or auxiliary data of the first storage format cannot be searched, processing text data or auxiliary data if the text data or auxiliary data of the second storage format can be searched by the second data search unit.

Music data processing system with concurrent reproduction of performance

A timbre information registration apparatus registers timbre variations which have different instrumental attributes and different modification degrees such that the registered timbre variations are selectively applied to instrument sounds synthesized by an electronic musical instrument. A memory has a matrix of memory locations arranged in rows and columns and assigned to individually register the timbre variations such that one timbre variation is selected by a row address and a column address. The individual timbre variations are categorized into a plurality of instrument kinds such that one instrument kind contains certain timbre variations having a common instrumental attribute. The individual timbre variations are also categorized into a plurality of version groups such that one version group contains certain timbre variations of the same modification degree. The column addresses are assigned to the respective instrument kinds such that the certain timbre variations belonging to one instrument kind are registered at the memory locations of one column. The row addresses are divided into a plurality of sections in correspondence to the plurality of the version groups such that the certain timbre variations belonging to one version group are registered at the memory locations specified by the row addresses of one section.

An automatic playing apparatus registers pattern data representative of a plurality of performance patterns in a storage, and sequentially designates performance patterns to form a music composition. The apparatus sequentially retrieve the pattern data of the designated performance patterns from the storage to reproduce a sequence of the designated performance patterns to undergo an automatic play of the music composition. The apparatus operates when incidentally designating an absent performance pattern which is not registered in the storage for substituting an available one of the registered performance patterns for the absent performance pattern so as to maintain the automatic play.

An electronic musical instrument has a composite sound source for generating a musical tone, and includes a first synthesizing circuit for creating a variety of timbres of the musical tone having a superior quality and a second synthesizing circuit for creating another variety of timbres of the musical tone having an inferior quality. The instrument admits designation information effective to designate one of the first and second synthesizing circuits to be activated and effective to designate a timbre to be created by the designated one of the first and second synthesizing circuits. A detector operates when the second synthesizing circuit is designated for providing a detection signal if the designated timbre can be also created by the first synthesizing circuit. A controller responds to the detection signal for altering the admitted designation information so that the first synthesizing circuit is activated in place of the second synthesizing circuit so as to create the designated timbre by the superior quality.

Data is set which instructs initiation of a phrase performance at a predetermined timing (beat) during a main automatic performance. When a switch for instructing execution of the phrase performance is operated during the main performance, such a control is performed to cause the phrase performance to start at the predetermined timing. Phrase performance instructing data is also prestored between main performance data. When the phrase performance instructing data is read out during the main performance, phrase performance data is read out from a phrase performance data memory in response to readout of the instructing data, so that the phrase performance is executed.

An automatic performance apparatus provides a performance data memory including plural storing areas each capable of storing different performance data independently. The performance data can be selectively written in and read from each storing area. Based on the performance data read from each storing area, a musical tone signal for an automatic performance is generated independently. When the performance data memory includes two storing areas, the performance data concerning two tunes or two parts can be stored. One of two automatic performances based on the performance data can be selectively played. In addition, two automatic performances can be also player simultaneouly, wherein a predetermined delay time can be provided between two automatic performances. Further, predetermined kinds of rhythm patterns are pre-stored in a rhythm pattern memory in order to perform the desirable rhythm pattern as an accompaniment of the automatic performance.

Automatic performance apparatus having plural memory areas

An automatic performance apparatus for recording performance data in a memory for controlling generation of musical tones, wherein the change or changes of pitch, key-on timing, key-off timing, note interval and/or note length data of a note can easily be effected. The note to be change is designated by positioning a cursor and operating a designation switch. The change of data of the note is achieved in accordance with the moving direction and amount of the cursor, for example, after the designation of the note.

Automatic performance apparatus

An automatic performance apparatus that can change the performance speed of desired sections in a piece of music automatically performed. The apparatus comprises a section designator for designating a specific section in the piece, a time evaluator for counting performance duration of the piece, a modifier for modifying either the duration of the specific section (or the duration of a section other than the specific section) by modifying the tempo of the automatic performance or duration of notes of the performance data so that the performance duration of the automatic performance becomes equal to the desired duration. Thus, the total duration of the piece is adjusted to the desired duration while maintaining the duration of the specified section (or the duration of the sections other than the specified section).
