In this embodiment, "automatic performance" refers to a song playback automatically performed based on performance data for one song (hereinafter, "song data") and one or several measures provided for accompaniment. For example, it is commonly used for both the meaning of playing back an accompaniment pattern that is automatically performed repeatedly based on performance data of a predetermined length (hereinafter referred to as “accompaniment pattern data”).

FIG. 1 is a functional block diagram of a tone setting device according to the embodiment.
This is realized by storage means such as M2 and RAM3 and a control operation described later. The manual timbre parameter storage unit A stores a large number (for example, 12) of parameters for determining a timbre at the time of generation of a musical tone of a manual performance based on the operation of the performance operator 4.
(Eight types) of timbre parameters. As the timbre parameter, a parameter that specifies a timbre number (specific parameters in this case are separately stored in, for example, a parameter memory or the like on the sounding unit side) or specific parameters (waveform type, EG parameter) , Filter coefficients, etc.). Also, not only the tone,
Parameters such as volume and effect may be stored together.

The automatic performance data storage section B stores a large number of song data (performance data for one song) and accompaniment pattern data such as automatic rhythm pattern data and automatic accompaniment pattern data. The automatic performance data storage section B includes a song data storage section for storing song data and an accompaniment pattern data storage section for storing accompaniment pattern data. Further, the song data and the accompaniment pattern include an optimum tone color parameter, an automatic performance tone color parameter, and performance sequence data to be described later. The automatic performance data typically includes a plurality of performance parts as described later.

The optimum timbre parameter is a timbre parameter for a manual performance suitable (matched) for the automatic performance data. The timbre parameter specifies one of the timbre numbers in the manual timbre parameter storage unit. Alternatively, specific parameters (waveform types, EG parameters, filter coefficients, and the like) different from those stored in the manual tone color parameter storage unit A may be used.
Further, not only the timbre but also parameters such as volume and effect may be stored together.

The automatic performance data selection section C selects one of a large number of automatic performance data according to a user's instruction in the accompaniment pattern selection mode or the song selection mode. Then, the optimum timbre parameters stored in the selected automatic performance data are supplied to the optimum timbre parameter buffer D.

On the other hand, the manual tone color selection section E selects a tone color number at the time of generation of a musical tone of a manual performance based on the operation of the performance operation element 4 according to a user's instruction. When a specific number (for example, “000”) is selected as the timbre number, the timbre parameter stored in the optimum timbre parameter buffer D is selected, and otherwise (for example, “001”).
““ 128 ”), the timbre parameters in the manual timbre parameter storage unit A are selected.

The manual tone color parameter buffer F stores the tone color parameters selected by the manual tone color selection section E. Then, the timbre parameters stored in the manual timbre parameter buffer F are supplied to the manual tone generation unit G, and a tone of a manual performance is generated. Further, the timbre parameters stored in the manual timbre parameter buffer F are supplied to the timbre parameter buffer I for automatic performance (described later) in accordance with an instruction from the automatic performance timbre change instructing section H. However, the timbre parameters in the manual timbre parameter buffer F are supplied to the automatic performance timbre parameter buffer I only when the automatic performance data is song data (change of the melody timbre of the song).

The automatic performance timbre parameter buffer I stores the automatic performance timbre parameters in the automatic performance data selected by the automatic performance data selector C. In addition,
This automatic performance timbre parameter buffer I is provided with a buffer for accompaniment pattern data and a buffer for song data, and a melody sound parameter buffer is set in the buffer for song data. The performance sequence data buffer J has an automatic performance data selection unit C.
The sequence data in the automatic performance data selected by is stored. Then, the timbre parameters of the timbre parameter buffer I for automatic performance and the performance sequence data buffer J
Are supplied to the automatic performance sound generation unit K, and the automatic performance tone is generated. When the automatic performance data includes a plurality of parts, a buffer is prepared for each part. When the automatic performance data is song data,
When an automatic performance tone color change instruction is issued, the contents stored in the tone color parameter buffer for a specific part such as a melody part are changed to tone color parameters stored in a manual tone color parameter buffer.

The manual sound generator G and the automatic performance sound generator K correspond to the tone generator circuit 8 for generating the manual sound and the automatic performance sound, respectively, but may be independent circuits or may be common circuits. The circuits may be shared by time sharing. Typically, it has a number of commonly used time-division channels.
Assign sounds for automatic performance.

FIG. 4 is a diagram showing an example of the format of the song data and the accompaniment pattern data in the embodiment. As shown in FIG. 4A, the song data is performance data of one song, , Melody part data, rhythm part data, bass part data, accompaniment part data, and the like. The melody part data is composed of melody tone color parameters and performance sequence data, and the rhythm part data is composed of rhythm tone color parameters and performance sequence data. Also, as shown in FIG. 4B, the accompaniment pattern is performance data of a few measures, and includes optimal tone color parameters, rhythm part data, base part data, accompaniment part data, and the like. The rhythm part data is composed of rhythm tone color parameters and performance sequence data, and the base part data is composed of bass tone color parameters and performance sequence data. The performance sequence data is, for example, event data such as musical notes recorded together with timing data such as the number of clocks from the beginning of the music indicating the readout timing.

The optimum tone color parameters of the song data and the accompaniment pattern data correspond to the automatic performance based on the song data or the accompaniment pattern data.
These are tone parameters (or a plurality of parameters) that are optimal for setting the manual performance when performing the manual performance, and are preset in accordance with the song data and the accompaniment pattern data.

FIG. 5 is a diagram showing an example of the relationship between the tone color number and the tone color parameter in the embodiment. The tone color number is, for example, a three-digit number of "001" to "128". The tone color name of “optimal tone color” is set to “000”, and the tone color parameter is a tone color parameter (optimal tone color parameter) in the automatic performance data. That is, when "000" is selected, the optimum timbre parameter of the automatic performance data is set as the timbre of the manual performance.

Hereinafter, "001" is a tone color parameter of a soft tone piano having a tone name "Mellow piano", and "00".
“2” is a timbre parameter of a flashy piano with a timbre name “Bright Piano”, and “003” is a timbre parameter of an electric piano with a timbre name of “Electric Piano”.
“021” is a tone parameter of a string whose tone name is “slow strings” and has a slow attack,
"2" is a tone parameter of a string of a middle attack with a tone color name of "middle string", and "023" is a tone parameter of a string of a fast attack with a tone name of "first string".

Here, the tone colors of the "mellow piano" and the "bright piano" are both the tone color of the acoustic piano, that is, basically the same tone color, but the "soft feeling"
The characteristics of the timbres are compared, such as "flashy feeling", and the frequency of switching between the two timbres by the player is high. Therefore, by arranging both tone color parameters in adjacent tone color numbers (“001” and “002” in this example), the performer can easily switch the tone colors. For example, when performing an operation such as incrementing or decrementing the tone color number when changing the tone color number, the operation is particularly easy.

Also, the tone colors of "slow strings", "middle strings" and "fast strings" are basically the same tone colors as strings (for example, violin), and the attack speed of these tones gradually increases. The characteristics of the timbres are contrasted so as to change. Accordingly, these are also adjacent tone numbers (in this example, “021”, “022”, and “02”).
By arranging them in 3 ″), the player can easily switch the timbre.

FIGS. 6 and 7 are flowcharts of the main part of the control program executed by the CPU 1 and show the part of the tone color setting program. Hereinafter, the control operation of the CPU 1 will be described based on each flowchart. In addition,
In the following processing, a timer called a “press and hold timer” is used.
By monitoring the time that is kept pressed, an instruction to change the melody timbre of the automatic performance is detected.

When the processing is started by turning on the power, etc.,
Whether or not the tone switch 51 has been turned on in step S1 (whether or not an on event has been detected; the same applies hereinafter).
Is determined, and if not turned on, the process proceeds to step S5,
If it is turned on, the electronic musical instrument is set to the tone color selection mode in step S2, and the process proceeds to step S3. Step S3
Then, the LED 61 corresponding to the tone switch 51 is turned on, and the other LEDs 62 and 63 are turned off. In step S4, the timer for keeping the pressing is started, and the process proceeds to step S5.

In step S5, it is determined whether or not the tone switch 51 has been turned off (whether or not an off event has been detected.
The same applies hereinafter. ) Is determined, and if it is not turned off, the process proceeds to step S7. If it is turned off, the timer is reset (stopped) in step S6, and the process proceeds to step S7. In step S7, it is determined whether or not the time counted by the pressing and holding timer is equal to or longer than a predetermined value (for example, about 1 second).
If the value is equal to or greater than the predetermined value, an instruction is made in step S8 to change the melody tone of the automatic performance, and the tone parameters of the manual tone parameter buffer F are stored in the parameter buffer for the automatic performance melody tone (the tone parameter buffer for the automatic performance). I). And
In step S9, the timer is reset and the process proceeds to step S10.

With the above processing, by holding down the tone color switch 51 for a predetermined time (for example, one second), the tone color parameter of the currently selected manual performance is set as the tone color parameter for the melody tone of the automatic performance. In other words, the processing of steps S7, S8, and S9 corresponds to claims 2, 5, and 7. In this embodiment, holding down the timbre switch 51 for a predetermined time is described in each of the claims "Tone of automatic performance". Corresponding to the instruction to change.

Next, in step S10, the accompaniment switch 5
It is determined whether or not No. 2 has been turned on. If it has not been turned on, the process proceeds to step S13; if it has been turned on, step S1
1 to set the electronic musical instrument to the accompaniment pattern selection mode,
In step S12, the LED corresponding to the accompaniment switch 52
While turning on 62, the other LEDs 61 and 63 are turned off, and the process proceeds to step S13.

Next, in step S13, it is determined whether or not the song switch 53 has been turned on. If the switch has not been turned on, the process proceeds to step S16 in FIG. Mode, and at step S15, the LED 63 corresponding to the song switch 53 is turned on, and the other LEDs 61 and 6 are turned on.
2 is turned off, and the process proceeds to step S16 in FIG.

In step S16, the increment switch (+) 54 or the decrement switch (-) 55
Is turned on. If none is turned on, the process proceeds to step S27. If any is turned on, in step S17, the current number (the timbre depending on the mode) is turned on according to the switch turned on. Number, accompaniment pattern number, or song number)
Proceed to step S18. In this process, the number is incremented by "1" by one ON event of the increment switch 54, and the number is decreased by "1" by one ON event of the decrement switch 55. Also, the number is changed to "1". When the increment switch 54 is turned on when the value is 128 ”(in this example, the maximum value of the number),“ 00 ”
0, and when the decrement switch 55 is turned on at "000", the number is changed to "128", whereby the number is set, and the number related to the mode selected by the mode switch operation described above. Is set here. That is, when the tone selection mode is selected,
The tone number set at that time becomes the initial value of the number here, and the increment switch 54
Alternatively, the number is increased or decreased by operating the decrement switch 55.

Next, in step S18, it is determined whether the mode is the tone color selection mode. If the mode is the tone color selection mode, the process proceeds to step S19. If the mode is not the tone color selection mode, whether the mode is the accompaniment pattern selection mode in step S22. It is determined whether or not the mode is the accompaniment pattern selection mode. If the mode is not the accompaniment pattern selection mode, the process proceeds to step S24 because the mode is the song selection mode.

In step S19, it is determined whether or not the currently set number (that is, tone number) is "000". If it is "000", in step S20, the tone color parameter in the optimal tone parameter buffer D is determined. Is copied to the manual tone parameter buffer F, and step S2
Go to 7. On the other hand, the currently set tone number is “00”.
If it is not 0 ", in step S21, the manual timbre parameter storage unit A corresponding to the set timbre number
Is copied to the manual tone parameter buffer F, and the flow advances to step S27.

With the above processing, if the timbre number "000" is set, the optimum timbre parameter of the currently selected automatic performance data is set as the timbre parameter of the manual performance. That is, in step S19,
The processing in S20 corresponds to claims 1, 4, and 6. In this embodiment, the timbre numbers "000" to "128" correspond to the "timbre group for specifying a timbre for manual performance" in each claim. And “000” corresponds to “specific tone color” in each claim. The process in step S21 is a normal tone color setting process.

If it is determined in step S18 that the mode is not the tone color selection mode but the accompaniment pattern selection mode in step S22, the process proceeds to step S23. In this step S23, the accompaniment pattern data storage unit (corresponding to the set number) The contents of the automatic performance data storage section B) are read out, the optimum timbre parameters are stored in the optimum timbre parameter buffer D, and the timbre parameters for automatic performance (rhythm timbre parameters, bass timbre parameters, etc.) are stored in the timbre parameter buffer for automatic performance. I, the performance sequence data is copied to the performance sequence data buffer J, respectively.
Proceed to step S25.

If the mode is not the accompaniment pattern selection mode in step S22, the operation is in the song selection mode.
At 24, the contents of the song data storage unit (in the automatic performance data storage unit B) corresponding to the set number are read out, and the optimal timbre parameters are stored in the optimal timbre parameter buffer D, and the timbre parameters for automatic performance (melody Timbre parameters, rhythm timbre parameters, etc.) to the automatic performance timbre parameter buffer I, and the performance sequence data to the performance sequence data buffer J, respectively.
Proceed to step S25.

Then, in a step S25, it is determined whether or not the set tone color number is "000".
If it is not "0", the flow proceeds to step S27, and if it is "000", in step S26, the optimum timbre parameter buffer D
(Optimal timbre parameter) is copied to the manual timbre parameter buffer F, and the flow advances to step S27.

In step S27, other processing is performed.
It returns to step S1 of FIG. In the other processing in step S27, the processing relating to the display of the timbre, the accompaniment pattern, and the content of the song corresponding to the selected timbre number, accompaniment pattern number, song number, and the like, and the timbre of the automatic performance has been changed. Processing to display a message to the effect, processing related to manual performance by operation of performance operators (sounding, mute, etc.),
Various processes related to the electronic musical instrument, such as a process related to the start / stop of the accompaniment pattern, a process related to the start / stop of the song, and a process related to the tempo change, are performed.

When the accompaniment pattern or the song number is changed in the state where the number "000" is set by the processing of steps S25 and S26, the optimum tone color parameter of the accompaniment pattern data or the song data is set to the manual performance. Is set in the manual timbre parameter buffer F as a timbre parameter.

As described above, by simply performing a simple operation of selecting a specific tone ("000" in the above example), the optimum tone for the automatic performance is set as the tone for the manual performance.

Further, the timbre switch is set for a predetermined time (for example, 1).
By simply performing a simple operation of holding down the button for a second, the tone of the manual performance can be set as the tone of the automatic performance.

Further, the tone of "Mellow piano" and "Bright piano", or "Slow strings",
Basically, the same timbres have different timbre parameters, such as the timbres of "Middle Strings" and "First Strings", and the timbres have different timbre characteristics. The timbre can be changed quickly and easily by a simple operation such as incrementing or decrementing the number.

The present invention is not limited to the above-described embodiment, but can be various modes. Although the example of “000” is shown as a specific tone number, other numbers such as “12”
Alternatively, a plurality of optimum timbres (optimal timbre parameters) may be stored for each automatic performance data, and a plurality of specific timbre numbers may be assigned to each optimum timbre in accordance with the stored timbres. "000" is the optimal tone 1,
The tone number “001” is the optimum tone 2 and the tone number “002”
May be the optimal tone 3.

The tone color numbers are not limited to those managed by a single serial number, but may be managed in several banks. For example, there are banks A and B, each having a tone number of “000” to “128”, and a specific tone number (for example, “000”) of each bank or a specific tone number of any bank is an optimum tone. You may make it become.

Further, in the embodiment, the specific timbre and the other timbres are associated with the timbre numbers. However, in another embodiment of the invention other than the third aspect, the tentative timbre name is associated with the specific timbre, Or other timbres may be selected by timbre name.

The user may be able to edit the optimum tone. Further, both a fixed (unchangeable) optimum tone color and a variable optimum tone color that can be edited by the user may be stored for each automatic performance data. In this case, each optimal tone may be assigned to a plurality of specific tone numbers as described above, or one of a fixed tone mode using a fixed optimal tone and a variable tone mode using a variable optimal tone. May be switched.

The optimum timbre parameters are not limited to those stored in the automatic performance data, but may be stored outside the automatic performance data. In this case, the automatic performance data and the optimal tone parameters may be associated with each other by some method (for example, the storage order of the data is adjusted,
One includes identification information of the other data, etc.).

In this embodiment, the increment switch and the decrement switch for selecting the tone number, the accompaniment pattern number, and the song number are shared by the tone color, the accompaniment pattern, and the song. A dedicated increment switch and decrement switch for number selection may be provided. Also,

An operator such as a numeric keypad for directly specifying a number may be used.

A selection operator is provided for each basic tone type (for example, piano, strings, etc.), a basic tone is selected by operating the selection operator, and a parameter is set by operating an increment switch or a decrement switch thereafter. You may make it select the tone of a different adjacent number. In this case, the tone color selected first by selecting the basic tone color may be the smallest tone number or the largest tone number among the adjacent tone color numbers. Further, the tone number may be an intermediate number or the tone number previously selected in the basic tone color.

The tone change command for setting the tone set for the manual performance as the tone for the automatic performance is given by pressing and holding the tone switch 51. An operator may be provided. Further, although the example of the automatic performance part for changing the timbre is described as a melody part, the timbre of a part other than the melody, for example, a bass part or an accompaniment part may be changed. In this case, it is preferable that the user can specify a part whose timbre should be changed.

Further, the tone generator circuit may be configured using dedicated hardware, the tone generator circuit may be configured using a DSP + microprogram, or the CPU +
The sound source circuit may be configured by a software program. Also, a combination of these may be used. Further, a plurality of tone generation channels may be formed by using one circuit in a time division manner, or one tone generation channel may be formed by one circuit.

The format of the automatic performance data (performance sequence data) is such that the occurrence time of the performance event is 1
"Event + relative time", expressed as the time from the previous event, "event + absolute time", which indicates the performance event occurrence time as the absolute time in the song or bar, the pitch and note length or rest of the note "Pitch (rest) + note length", which represents performance data with the rest length, reserves a memory area for each minimum resolution of performance, and stores performance events in the memory area corresponding to the time when the performance event occurs. Any format such as a stored “solid format” may be used.

Further, the automatic performance data processing method is a method of changing the processing cycle according to the set tempo. The processing cycle is constant, and the value of the timing data in the automatic performance data is changed according to the set tempo. The changing method and the processing cycle are constant, and any method such as a method of changing the counting method of the timing data in the automatic performance data in one process according to the tempo may be used.

The automatic performance data for a plurality of channels (parts) may be stored in a form in which data of a plurality of channels are mixedly stored, or the data of each channel is stored separately for each track. It may be in the form.

Further, in the memory, time-series performance data may be stored in a continuous area, or data scattered and stored in discrete areas may be separately managed as continuous data. (That is, it is only necessary that the data can be managed as time-series continuous data, and it does not matter whether the data is continuously stored in the memory).

The processing program (including the tone color setting program) and various data used for the processing are stored in an external storage medium.
Alternatively, it may be supplied from an external device to an electronic musical instrument or a personal computer via a communication interface.

In addition to the dedicated MIDI interface, RS-232C, USB (Universal Serial Bus), IEEE1394 (Itriple 1)
394) and other general-purpose interfaces
An interface may be configured. In this case, MID
Data other than the I message may be transmitted and received at the same time.
