Abstract

PURPOSE:To obtain a musical sound which is extremely close to the actual performance of a player by converting score data into performance data automatically based on score interpretation data and performance restriction data relating to specific musical instruments. CONSTITUTION:A CPU 1 starts a process based on a previously set control program, reads the score data out of a floppy disk 8 first, and writes the data in a RAM 2 through a data I/O control part 7 and a bus 9. Then the CPU 1 converts the score data which is stored in the RAM 2 into 1st performance data based on a player data base 3, writes it in the RAM 2, and converts the data into a 2nd performance data according to a musical instrument data base 4. Then the performance data is read out of the RAM 2 and supplied to a musical sound generation control part 6, which generates a musical sound in order based on the performance data. Consequently, the score data is converted into the performance data automatically according to the physical and technical restrictions of the player to enable automatic performance which is rich in humanity and expression.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an automatic performance device that enables extremely natural automatic performance.

``Prior Art'' In conventional automatic musical instruments, when 2j9 data is input, there is a method of performing an automatic performance faithfully in accordance with the musical score data. However, there was a problem that automatic performance according to the request data resulted in an unhuman performance, as listed below, for example.

θ) Play a phrase that you shouldn't be able to play.

■In keyboard instruments, when a key is pressed with the pinky finger, the sound that should be 1 note becomes small becomes 7 notes, which is the same as other notes.

■In wind instruments, there are no pauses in sound due to breaths, and continuous sound is produced.

■There are no peculiarities caused by the performer.

In view of the above-mentioned circumstances, in the automatic performance of certain types of electronic musical instruments, it is possible for the user to appropriately convert parameters such as bass city and note length.

This has made it possible, for example, to reproduce the habits of a particular performer in an automatic performance, and to perform an automatic performance that is humane and rich in expression.

[Problems to be Solved by the Invention] By the way, in order to achieve human-like and expressive automatic performance using the above-mentioned technology, it is necessary to manually change the velocity, note length, etc. for each note of the musical score data. This is complicated, inconvenient, and impractical.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an automatic performance device that can automatically convert musical score data.

``Means for Solving the Problems J'' In order to solve the above problems, the present invention takes musical score data indicating the musical score of a song as input data, converts this musical score data into performance data indicating the performance state of the musical instrument, An automatic performance device that performs automatic performance based on data, which stores in advance musical score interpretation data for interpreting what performance state the musical score data corresponds to, and performs manual musical score data based on the musical score interpretation data. a first conversion means that converts the inputted first performance data into first performance data and outputs the first performance data; and a first conversion means that stores in advance performance constraint data for each instrument indicating the influence of the musical sound due to the musical instrument performance by the performer; The present invention is characterized by comprising a second converting means for converting into second performance data based on the performance constraint data related to a predetermined musical instrument.

When musical score data is manually input to the converting means, this musical score data is converted into first performance data that is the ideal performance image of the performer based on the musical score interpretation data. next,
When the first performance data is supplied to the second conversion means, based on the performance constraint data related to a predetermined musical instrument, the first performance data is considered to be based on constraints such as phrases in actual musical instrument performances by humans. is converted into second performance data.

As a result, the musical tones output by the automatic performance device of the present invention are
The result is a musical tone that closely resembles the musical tone actually played by the performer.

[Embodiment J Next, an automatic performance device according to an embodiment of the present invention will be described with reference to FIG.

In the figure, 1 is a CPU (central processing unit), which is configured to control other components based on a preset control program. Further, 2 is a RAM (read/write memory) in which musical score data and performance data are read/written in accordance with control signals from CI) UI. Here, musical score data is data that represents the musical score itself, while performance data is data in which note length, velocity, pitch adjustment, etc. are set based on the musical score data.

Next, reference numeral 3 is a performer database, in which playing habits of various performers are stored, for example, as shown below.

A habit of strength and weakness of 0 beats.

■Habit of changing performance speed for each phrase.

■Interpretation of ritardando, fermata, cresciendo, etc.

In other words, the performer database 3 stores data for converting musical score data into performance data corresponding to the performance imagined by each musician when looking at the musical score.

Next, reference numeral 4 represents musical instrument performance data, in which correction data based on the physical limitations of each performer is stored for each musical instrument, as shown below, for example.

■On the piano, black keys are harder to play than white keys, so the velocity will be lower, the musical tone will be slightly distorted at the point where the finger slips, and it is difficult to play distant notes, so the velocity will be lower and the timing will be slightly delayed. Constraints.

■On bass, it is easy to play slurs within the same string, but it is difficult to play slurs between different strings, and there are limitations such as the musical tone being slightly distorted.

■When playing chords that are difficult to play on the guitar, the sound produced by some strings is muted.

■Some piano players have limitations such as a weak pinky finger, which causes the notes played with the pinky finger to be small, and a short finger, which makes it impossible to play chords that are more than an octave apart.

- Constraints that the timing, volume, etc. of each sound vary (note that the rate of variation varies depending on each performer).

In other words, the musical instrument performance database 4 stores correction data for processing performance data based on physical and technical constraints when playing a musical instrument.

Next, 5 is a display, which displays information supplied via bus 9. Further, reference numeral 6 denotes a musical tone generation control section, which generates musical tones in accordance with performance data supplied via the bus 9. Further, 7 is a data I10 control unit, and CP
The musical score data is read from the floppy disk 8 under the control of the UI, and the musical score data is transferred to the RAM 2.

Next, the operation of this embodiment will be explained with reference to FIG. Note that FIG. 2 is a flowchart of a processing program set in the CPUI.

In the figure, when the process is started, musical score data is read from the floppy disk 8 in step SP1, and written into the RAM 2 by sequentially controlling the data I10 control unit 7 and the bus 9.

Alternatively, music may be automatically composed using a program or the like in step SPI, and the musical score data created by this automatic composition may be written into the RAM 2.

Next, when the process proceeds to step SP2, the musical score data stored in the RAM 2 is converted into performance data based on the performer database 3. For example, a certain piano player A
If you interpret the fermata as "if one fermata follows several times, only the last one represents a cessation of beat, while the others are somewhat muted, like breath breaks" (i.e., this If data indicating the interpretation is included in the performer database 3), performance data is created and written to the RAM 2 in accordance with this interpretation.

Next, when the process proceeds to step SP3, step S
The performance data created in P2 is converted based on the musical instrument performance database 4. For example, if a phrase that requires finger-crossing is detected in the piano performance sound, the timing, velocity, etc. of the note played by finger-crossing are adjusted so that it is 0<Fun.

Next, when the process proceeds to step SP4, one unit of performance data is read out from the RAM 2 and supplied to the musical tone generation control section 6. Then, the musical tone generation control section 6 generates musical tones based on the supplied performance data.

Next, when the process proceeds to step 51)5, it is determined whether or not the music has ended, and if the determination is 1NO, the process returns to step SP4. In step S P4, the next unit of performance data is read from 1'LA M2,
A musical tone is generated via the musical tone generation control section 6. Thereafter, step SP4.5 is repeatedly executed until the music ends, and performance data is sequentially output. Then, when the music ends, the process returns to step SPI, and the next musical score data is read from the floppy disk 8.

"Effects of the Invention" As explained above, according to the automatic performance device of the present invention, musical score data can be automatically converted into performance data according to the physical and technical constraints of the performer, so it is possible to It is possible to perform expressive automatic performances.
