Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device for reproducing a musical tone based on pronunciation information defining the musical tone.

[0002]

2. Description of the Related Art Conventionally, an automatic performance device called a rhythm machine has been known.
Song data that stores pattern data that stores multiple pronunciation information that make up a phrase, and pattern control information that directs the selection of a phrase (pattern data).
When playing a song, the pattern control information (for example, pattern number) stored as song data is sequentially read out, and the pronunciation information is sequentially read out from the corresponding address of the pattern data to produce a sound. Has been done.

FIG. 15 is a memory layout diagram showing the relationship between song data and pattern data. Pattern control information (here, pattern numbers) for a plurality of songs (tunes) is arranged in the song data. Further, in the pattern data, pronunciation information (note here) is arranged for each of the patterns 1, 2 ,.

For example, when the reproduction of the song 1 is designated, the area of the song 1 of the song data is referred to, and the pattern control information constituting the song 1 is sequentially referred to. For example, when the pattern 1 is referred to, the area of the pattern 1 of the pattern data is referred to this time, the pronunciation information arranged in the area is sequentially referred to, and the musical sound is reproduced in accordance with the pronunciation information. This conventional method has a merit that memory can be saved as compared with the method of directly storing pronunciation information, since relatively short phrases are often repeated, especially for accompaniment patterns such as rhythm patterns. Also, if this method is adopted, it is possible to easily delete, add, or replace patterns in the song.

[0005]

The accompaniment pattern is composed of, for example, four measures, while the melody is generally composed of a pattern, such as 32 measures, which is considerably longer than the accompaniment pattern. Here, a case will be considered in which the above-mentioned conventional method is adopted to store music in which a melody having a length of 32 bars is played while an accompaniment pattern having a length of 4 bars is repeated eight times. .

In this case, as a storage area of pattern data corresponding to one pattern control information shown in FIG.
If a large area is secured so that the amount of data for 16 measures can be stored according to the length of the melody, it is necessary to store the accompaniment pattern in the pattern data repeatedly eight times. As a result, the amount of data in the accompaniment portion is increased, and the original merit of the above method of reducing the memory capacity is lost.

On the other hand, even if the storage area of the pattern data corresponding to one pattern control information is a small area that can store only the data amount of four measures in accordance with the accompaniment pattern, eight different pattern numbers (pattern control information ), It is necessary to store the same accompaniment pattern for the eight pattern data. Therefore, also in this case, duplicate storage of the accompaniment pattern is unavoidable.
It is impossible to reduce the memory capacity, which is the original merit.

Further, when the length of the pattern data is matched with the accompaniment pattern, as shown in FIG. 16, the melody is cut into small pieces according to the length of the accompaniment pattern, and a plurality of patterns having the same accompaniment pattern are formed. -It will be necessary to store the data separately, but when the melody is cut into small pieces and stored as a pattern, the boundaries between the individual phrases that make up the melody and the accompaniment pattern are often different. It also gives a feeling of strangeness.

In view of the above circumstances, it is an object of the present invention to provide an automatic performance device in which it is not necessary to break the melody into small pieces when the accompaniment pattern and the melody are mixed and the memory capacity is reduced. And

[0010]

The automatic performance device of the present invention which achieves the above object, is: (1) First storage means for storing pattern information in which a plurality of pronunciation information defining one musical tone is arranged. (2) Second storage means for storing pattern control information designating pattern information and pronunciation information in a mixed manner (3) Music tone generation means for producing a musical tone based on the pronunciation information (4) Storage in second storage means The generated pronunciation information and the pattern control information are referred to, the referred pronunciation information is sent to the musical tone generation means, and the pattern information stored in the first storage means corresponding to the referred pattern control information is referred to. It is characterized in that it is provided with a pronunciation control means for sending the pronunciation information constituting the pattern information to the tone generation means.

Here, in both the pronunciation information and the pattern control information stored in the second storage means, a generation duration of a musical tone represented by the pronunciation information or a series of patterns represented by the pattern control information designated by the pattern control information. It is effective that both the information indicating the musical tone generation duration time and the information indicating the time at which the next pronunciation information or pattern control information should be referred to are attached.

Further, the pattern information may be allowed to include pattern control information as well as pronunciation information.

[0013]

In the automatic performance apparatus of the present invention, the pattern control information and the pronunciation information are mixedly stored in the second storage means of the above (2), and the pattern control information is stored in the first storage means of the above (1). Since the pattern information designated by the information is stored, the accompaniment pattern is stored as pattern information in the first storage means, the pattern control information is stored in the second storage means, and the pronunciation information is stored for the melody. Is stored directly in the second storage means,
It is not necessary to forcefully match the length of the accompaniment pattern with the length of the melody, and the memory capacity of the accompaniment pattern is reduced, which is the same advantage of the conventional method.

Here, by adding both the generation continuation time and the information indicating the time to both the pronunciation information and the pattern control information, the pronunciation is stored in the second storage means of the above (2). Both information and pattern control information
Can easily be mixed. As described above, in the present invention, since both the pronunciation information and the pattern control information are mixed in one storage means, this idea is developed and stored in the first storage means of (1) above. If the pattern information (arrangement of a plurality of pronunciation information) to be included can include the pattern control information together with the pronunciation information, the degree of freedom in storing the pronunciation information is increased.

[0015]

Embodiments of the present invention will be described below. FIG. 1 is a block diagram of an automatic performance device according to a first embodiment of the present invention. This automatic performance device has a CPU 11 and a ROM 1
2, RAM 13, tone generating means 14, operation panel 15,
And a display 16 which are provided with the data bus 1
They are connected to each other by 0.

The CPU 11 processes the information input from the operation panel unit 15 according to the program stored in the ROM 12 and by using the RAM 13, displays the necessary information on the display unit 16, and further outputs the pronunciation information to the musical tone generating means. 14 to instruct the musical tone generating means 14 to generate a musical tone. RA
The M13 also has a pattern data storage area and a song data storage area described later.

FIG. 2 is a diagram showing an operation panel shown by blocks in FIG. The song key 21 and the pattern key 22 are used to switch between a song performance mode in which a song is played or recorded and a pattern performance mode in which a pattern is played or recorded. The track selection key 23 is used to select the number of the track to be recorded. Tones (4 in this embodiment) are assigned in advance tones suitable for drum, bass, piano, and melody, respectively.

The ten key 24 is used to select a song number or pattern number. A stop key 25, a play key 26, and a record key 27 are used to instruct stop, playback, and recording of a song or pattern, respectively. When a performance is performed using the keyboard 28, a tone color assigned to a track previously selected by the track selection key 23 is sounded.

Here, a pattern can be assigned to an arbitrary key by pressing the arbitrary key on the keyboard 28 and selecting a pattern number with the ten keys 24. Further, at this time, since the transposition amount instructing how much the pattern is transposed and played is inquired, the transposition amount can be stored by designating with the ten keys 24.

When the key to which the pattern is assigned is pressed, the performance of the pattern is started. The pattern is repeatedly played until the pressed key is released. If a key assigned with another pattern is pressed while a certain pattern is being played, the playing of another pattern is started in addition to the currently playing pattern. The tempo knob 29 is used to instruct the pattern to be played and the tempo of the song.

When the record key 27 is pressed to record, the pitch designated by the keyboard 28, the timing of key depression and key release, the key depression speed, and the track number selected by the track selection key 23 are displayed. , Is stored in the RAM 13 as pronunciation information. At this time, when the pattern performance mode is designated by the pattern key 22, the pronunciation information is R
When the song performance mode is specified by the song key 21 and stored in the pattern data storage area of the AM 13, the pronunciation information is stored in the song data storage area of the RAM 13. At this time, the tempo designated by the tempo knob 29 is stored in the pattern data recording area or the song data storage area of the RAM 13 as the tempo of the pattern or song.

When a key to which a pattern is assigned is played in the recording state and the song playing mode is designated, the pattern number, key depression / release timing, and key depression speed are pattern controlled. RAM1 as information
3 is stored in the song data recording area. Figure 3 shows R
FIG. 4 is a conceptual diagram of the storage contents of the pattern data recording area and the song data storage area in the AM 13, and FIG. 4 is a diagram schematically showing the configuration of the pattern data recording area and the song data storage area.

As shown in FIG. 3, the song data storage area stores both pronunciation information representing melody (represented by notes in FIG. 3) and pattern numbers (pattern control information). . Further, the pattern data storage area stores an accompaniment pattern as shown in the figure, and by the pattern number stored in the song data storage area,
The pattern data storage area corresponding to the pattern number is designated.

Next, the contents of the pattern data and the song data will be described with reference to FIG. Each pattern data and each song data has a structure for storing a note (pronunciation information) or a pattern (pattern control information) between a header and a footer.

The header stores the performance tempo, name, time signature, etc. of each pattern or song. The footer indicates the end of each pattern and song. Track number, note number, velocity, step time and duration are stored in the pronunciation information. The track number is a parameter that specifies a tone color at the time of sounding, and at the time of sounding, the tone color assigned to each track is sounded.

The note number is a parameter for designating the pitch at the time of sounding. For example, when the note number = 60, the note is sounded at the pitch C (C4) at the center of the piano. When the track number is 0 (drum), the rhythm sound pre-assigned to the note number (for example, note number = 3
6 is played on the bass drum, and note number 38 is played on the snare drum).

Velocity is a parameter for controlling the volume at the time of sound generation, and the volume increases as the value increases. The step time is a parameter that indicates the time at which the information stored at the current read address, that is, the information to be referred to next, is referred to. At the time of referring to a certain pronunciation information, the read address has already been updated to the address of the information to be read next. The information at the current read address, that is, the information to be referred to next is, for example, if the note A shown in FIG. 4 is currently being referred to, the B stored next to the note A is stored. Refers to a pattern. The CPU measures the time represented by this step with the built-in timer, and when the instructed time comes, it refers to the information at the current read address.

The duration is a parameter for instructing the duration of sound generation, and the larger this value, the longer the sound is continuously sounded. On the other hand, the pattern control information stores the pattern number, velocity, transpose, step time and duration. The pattern number is a parameter that specifies the number of the pattern to be called during the song performance.

Velocity is a parameter for controlling the volume during pattern play, and the product of this value and the velocity of each tone generation information in the pattern data is given to the tone generating means. The transpose is a parameter for instructing the transposition of the pattern to be played. For example, when this value is +2, the pattern is transposed two semitones up and played.

The step time is a parameter indicating the time to refer to the information at the current read address, like the step time in the pronunciation information. CPU
Measures the time represented by this step time with the built-in timer and refers to the information at the current read address when the instructed time comes. The duration is a parameter that indicates the performance duration of the selected pattern. The larger this value, the longer the playback of the pattern is continued.

Further, in the present embodiment, as shown in FIG. 3, by further storing pattern control information in the pattern data, another pattern can be called from a certain pattern. . Fig. 5 shows keyboard 2
8 is a flowchart of a key depression processing routine that is activated when any one of keys 8 is depressed.

In step 5_1, it is determined whether or not the recording state is set. If it is in a state other than the recording state, that is, in the reproducing state, the process proceeds to step 5_2 and it is determined whether it is a song playing mode or a pattern playing mode. It If it is determined to be the song playing mode, the process proceeds to step 5_3, and it is determined whether or not a pattern is assigned to the depressed key. If the pattern is assigned, the process proceeds to step 5_4, and the pronunciation of the pattern is started.
The pattern start processing routine corresponding to step 5_4 will be described later.

Further, it is determined in step 5_2 that it is not a song (that is, a pattern), or even if it is determined that it is a song, in step 5_3 it is determined that no pattern is assigned to the key pressed. Then, the process proceeds to step 5_5, and the musical tone of the note corresponding to the depressed key is pronounced. On the other hand, step 5_1
If it is determined that the recording state is set in step 5,
Proceeding to _6, similarly to step 5_3, it is determined whether or not a pattern is assigned to the depressed key. If the pattern is assigned, the process proceeds to step 5_7, and the pattern control information corresponding to the assigned pattern is registered in the song data recording area. On the other hand, if it is determined in step 5_6 that there is no pattern assigned to the pressed key, the process proceeds to step 5_8, and the note (pronunciation information) corresponding to the pressed key is generated.
Is registered. At this time, as described above,
When the pattern playing mode is specified by the key 22 (see FIG. 2), the pronunciation information is registered in the pattern data storage area, and when the song playing mode is specified by the song key 21, the pronunciation information is the song. -Registered in the data recording area. In step 5_7, the note registered in step 5_8 is sounded.

FIG. 6 is a flow chart of a key release processing routine which is activated when any key on the keyboard 28 is released. In step 6_1, it is determined whether or not the recording state is set, and if it is in a state other than the recording state, that is, in the reproduction state, the process proceeds to step 6_2 and it is determined whether the song performance mode or the pattern performance mode. If it is determined to be the song playing mode, the process proceeds to step 6_3, and it is determined whether or not a pattern is assigned to the released key. If the pattern is assigned, the process proceeds to step 6_4, and the sounding of the pattern is stopped. The pattern stop processing routine corresponding to this step 6_4 will be described later.

Further, in step 6_2, it is determined that it is not a song (that is, a pattern), or even if it is determined that it is a song, it is determined in step 6_3 that the pattern released is not assigned to the released key. Then, the process proceeds to step 6_5, and the tone of the note corresponding to the released key is muted. On the other hand, step 6_1
If it is determined that the recording state is set in step 6,
Proceeding to _6, similarly to step 6_3, it is determined whether or not a pattern is assigned to the released key. If the pattern is assigned, the process proceeds to step 6_7, and the duration is registered in the pattern control information registered in the song data storage area when the key is pressed. On the other hand, if it is determined in step 6_6 that there is no pattern assigned to the released key, the process proceeds to step 6_8,
The duration of pronunciation information corresponding to the released key is registered.

Next, the process of starting and stopping the performance of patterns and songs will be described. FIG. 7 is a diagram showing a play register prepared for managing the performance of patterns and songs. By registering necessary information in this play register, the performance of the pattern or song is started.

In FIG. 7, pattern information or song number is stored in NUMBER. NUMBER =
Empty indicates that neither pattern nor song is registered in the register. The address of a storage area in which performance data (that is, pattern data or song data) is stored is stored in the ADRS.

STEP is a counter, and the step time value of the pattern data or song data is copied. When this value is other than 0, this value is decremented by 1 by an interrupt process (not shown) called at regular intervals by a timer incorporated in the CPU, and this value becomes 0.
In the performance processing routine described later, the ADR
Performance data is sequentially read from the address stored in S, and processing such as musical tone generation is performed.

The maximum number of registers is stored as MAX_R. FIG. 8 is a flowchart of the pattern / song start processing routine. In step 8_1, the counter i is initialized to 0, and in step 8_2, the play register shown in FIG. 7 is referred to, and it is determined whether or not NUMBER [i] is empty. If it is not empty, step 8_
In step 3, the counter i is incremented until the counter i reaches the maximum value (step 8_4).
It is determined whether [i] is empty. If NUMBER [i] is empty in step 8_2, the process proceeds to step 8_5, the start address of the performance data is calculated from the current pattern number or song number, and step 8_6
In step 1, the start address is stored in the register ADRS, and the step time value is stored in STEP.

In step 8_7, NUMB
The pattern number or song number is stored in ER. Figure 9
Is a flow chart of a pattern / song stop processing routine. The vacancy is assigned to NUMBER corresponding to the designated pattern number or song number in the play register. However, if the song is stopped, all NUM
Substitute an empty space for BER.

FIG. 10 is a flowchart of a performance processing routine that is called from the main program at regular intervals (for example, 10 msec). By the operation described below, performance processing is performed in the same performance processing routine regardless of whether it is a song or a pattern. First, in step 9_1, the counter i is initialized, and in steps 9_2 and 9_3, the play register shown in FIG. 7 is searched. When NUMBER is empty, or NUM
S corresponding to the NUMBER even if the BER is not empty
When TEP is not 0, the procedure proceeds to step 9_13, the counter i is incremented, and until the counter i reaches the maximum value (step 9_14), NUMBER that stores anything other than empty and STEP that stores 0 is searched. To be done. NUMBER is not empty and ST
If a register with EP = 0 is found, step 9_4
At, the performance data is read from the address stored in the ADRS. That is, if it is sound generation information, the track number, volume (note number), velocity, step time and duration are read out, and if it is pattern control information, the pattern number, velocity, transpose, step time and duration are read out.

In step 9_5, it is determined whether the read performance information is sound information (note) or pattern control information (pattern). If it is sound information, sound processing is performed (step 9_6) and pattern control information. If so, pattern start processing is performed (step 9_7).
In step 9_8, the address ADRS is updated, and the address of the performance data to be read next is stored in ADRS. When the value of ADRS becomes equal to the address of the final data (footer) of the pattern or song (step 9_9), it is determined in step 9_10 whether it is a pattern or a song. In the case of a pattern, the head address of the pattern is substituted into ADRS in step 9_11. On the other hand, in the case of a song, in step 9_12, all the NUMBERs in the play register are filled with empty spaces, and the performance ends.

As described above, it is possible to save memory by creating the accompaniment pattern with the minimum required amount of data as in the conventional art and playing it a required number of times repeatedly, and by directly storing the melody etc. Playback is possible. In this embodiment, the information stored as the pattern control information is the pattern number, the pelocity, the transpose, the step time and the duration, but in addition to this, the number of repetitions and the playing time (absolute time),
You may make it memorize | store tempo etc.

FIG. 11 is a block diagram of an automatic performance device according to the second embodiment of the present invention. The difference from the first embodiment of the present invention is that a disk storage means 17 is added. Further, the RAM 13 includes a performance data buffer described later. In the second embodiment, the song data and the pattern data are stored in an external storage means such as a floppy disk.

Since it takes time to read the data stored in the floppy disk or the like, a method of reading the data in advance and temporarily storing it in the RAM is generally used. At that time, the reading of the data from the disk and the sending of the read data to the musical tone generating means operate as independent tasks. Data is passed between the tasks via the performance data buffer in the RAM 13.

The operation panel section, the pattern data storage area and the song data storage area, and the key depression and key release processing of the keyboard are the same as those in the first embodiment described above, and a description thereof will be omitted. The difference between the start and stop processings in the first embodiment is that the steps are stored in a play register (see FIG. 7) for managing the performance of patterns and songs.
However, in the first embodiment, the time (relative time) from the previously read data is shown, whereas in the present embodiment, the time (absolute time since the play key 26 was pressed to start the performance) ) Is the point. Further, in the first embodiment, S
Although TEP was subtracted in the interrupt processing, it is referred to in the performance data reading task described later in this embodiment.

FIG. 12 is a diagram schematically showing a performance data buffer for passing data between the data reading task and the performance processing task. The performance data buffer stores time (performance time), track number, note number, velocity, and duration.
The performance time (time) represents the time from when the play key 26 is pressed to start the performance until the musical tone is generated.
In a performance processing task, which will be described later, a timer built into the CPU measures the time from the start of the performance, and when the measured time coincides with the performance time (time), a read pointer indicating a read address of the performance data buffer is read. The pronunciation data (track number, note number, velocity, duration) is read from the address pointed to,
It is sent to the musical sound generating means.

Track number, note number, velocity,
Since the duration and duration are the same as the data stored in the pattern data storage area and the song data storage area, description thereof will be omitted. FIG. 13 is a flowchart of the performance processing task. The performance processing task is called when the power is turned on and is repeatedly executed thereafter.

Initialization is performed in step 13_1, and in step 13_2, it is determined whether the read pointer indicating the read address of the performance data buffer and the write pointer indicating the write address match, and they do not match. At this time, that is, when sound data exists in the performance data buffer, in step 13_3, the time indicating the absolute time from the start of the performance and the value measured from the start of the performance by the timer built in the CPU ( If the clock is equal to or longer than the time, the tone generation data is read from the address indicated by the read pointer and sent to the tone generating means (step 13_4), and then read. The pointer is updated (step 13_5).

FIG. 14 is a flow chart of the data reading task. The data read task is called after the start processing routine (see FIG. 8) when the play key 26 is pressed. At step 14_1, the play register (see FIG. 7) is searched for a value other than vacant NUMER, that is, a STEP having the minimum value among STEPs corresponding to the NUMBER of the currently playing song or pattern. If none of the songs and patterns have been played, N is returned in step 14_2.
It is judged to be O, and processing for stopping the performance (step 14_12)
After that, the data reading task is ended.

When the register having the smallest STEP value is detected, the pattern data storage area or the song
From the ADRS indicating the address in the data storage area, the track number, pitch, velocity, step time, and duration are read for the pronunciation information, and the pattern number, velocity, transpose, step time, and duration for the pattern control information. Read out the sequence (step 14_3).

Further, it is judged whether the performance information read out at the step time is the pronunciation information or the pattern control information. If it is the pronunciation information, the pronunciation information is copied to the performance data buffer in step 14_5.
At that time, the performance time STEP of the play register is copied as the time of the performance data buffer. Step 14
In _6, the write pointer indicating the write address of the performance data buffer is updated.

When it is determined that the performance information read in step 14_4 is pattern control information,
Proceeding to step 14_7, pattern start processing is performed. In step 14_8, the address ADRS is updated, and the address of the performance data to be read next is A
Stored in DRS. When the value of ADRS becomes equal to the address of the final data (footer) of the pattern or song (step 14_9), it is determined in step 14_10 whether the pattern or song. In the case of a pattern, the start address of the pattern is ADRS in step 14_11.
Is assigned to.

On the other hand, in the case of a song, step 14_1
At 2, the vacancy is assigned to all the NUMBERs in the play register, and the performance ends. In step 14_13, step STEP is updated. As mentioned above,
The playing time after the play key is pressed is stored in STEP, and the address ADR is written in STEP before updating.
By adding the step times read from S, the time to read the data of this address is set.

As shown in the second embodiment, the song
The data and pattern data may be stored in an external storage medium such as a floppy disk.
