DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pitch-to-MIDI device which is attached to a stringed instrument such as a guitar, detects the presence or absence of a string vibration and detects the pitch, and converts the string into MIDI information.
・ Converter (Pitch To Converto)
r) and M such as pitch-to-MIDI converter
The present invention relates to a guitar synthesizer to which an IDI musical instrument is connected and which outputs MIDI information input from the outside to a built-in sound source (or an external sound source).

[0002]

2. Description of the Related Art Conventionally, in an electronic musical instrument, a plurality of parts (in an orchestra or a band,
Sound source resources for generating musical tones corresponding to one musical instrument), and a plurality of types of musical instrument sounds can be simultaneously generated in each part. When inputting a performance of a stringed instrument such as a guitar, an electronic stringed instrument is used to input the MI to the sequencer.
In this case, performance information such as DI information is input. In this case, MIDI information generated by all strings is input to one part in a POLY mode, and MIDI information generated for each string is input to each string. Two types of performance input have been performed in the MONO mode for inputting to a part assigned to each part.

[0003] The MIDI information includes note information for instructing generation and stop of a musical sound, and control information (pitch bend information, vibrato information, expression, etc.) for changing the generated musical sound, for example, adding an effect.
Generally, the control information is applied to each part.

[0004]

In the POLY mode,
Since the performance information generated in all the strings is input to one part, an effect based on the control information generated in a certain string is given to all the musical tones generated in this part.
For example, when pitch bend is applied to the tone signal of the first string in a state where tone signals of the first string and the second string are generated, the second tone is generated.
Pitch bend is applied to the tone signal generated by the string. Accordingly, performance information that is not intended by the player is input to the sound source, resulting in a performance that is unpleasant in hearing.

In the MONO mode, an independent part is assigned to each string, so that there is no audibility problem as in the POLY mode. However, parts are required as many as the number of strings. For example, six parts are required to input the performance information of the guitar. Usually, since the number of parts that can generate a sound source is limited, if six parts are occupied for inputting performance information of one tone such as a guitar tone, for example, parts that can be used by other tone colors are used. The number decreases, and rich performance cannot be performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a performance information output device capable of performing a performance as intended by a player, even though only a small number of parts are used.

According to one aspect of the present invention, a vibration of each string of a stringed musical instrument having a plurality of strings is converted into performance information, and the performance information is converted to a sound source. In a performance information output device that outputs to a plurality of parts, the performance information of non-adjacent strings in each string is output to the same part, and the performance information of adjacent strings in each string is output to different parts. .

Usually, in a stringed instrument such as a guitar, the adjacent strings, for example, the first string and the second string are often played so as to exert different effects at the same time, but non-adjacent strings, for example, the first string. , The third string and the fifth string are rarely performed simultaneously with different effects. Therefore, in the present embodiment, the performance information of adjacent strings to which different control information may be given is output to different parts so that different effects can be applied, and non-adjacent strings where different effects are hardly applied are provided. By outputting the string performance information to the same part, rich performance expression of the stringed instrument is enabled even though only fewer parts are used than the number of strings.

Another aspect of the present invention is a performance information output device for outputting performance information input from a plurality of performance information sources arranged outside to a sound source.

According to this aspect, when the first mode is selected, a state corresponding to the so-called MONO mode is established. When the second mode is selected, performance information from non-adjacent strings is output to the same part, and performance information from adjacent strings is output to different parts. Therefore, the performance expression of the stringed instrument can be automatically changed to a state where only a part less than the number of strings is used by the selection operation of the mode selection means.

Mode selection means for selecting any one of the modes, and output means for outputting the performance information respectively input from the performance information source to a sound source having a plurality of parts, wherein the output means comprises: When the first mode is selected, the performance information from the performance information source is output to independent parts respectively corresponding to the performance information sources. When the second mode is selected, the performance information is output. Performance information from non-adjacent performance information sources at the source is output to the same part.

According to this aspect, when the first mode is selected, a state corresponding to the so-called MONO mode is established. When the second mode is selected, performance information from non-adjacent performance information sources is output to the same part, and performance information from adjacent performance information sources is output to different parts. Therefore, the performance expression of the stringed instrument can be automatically changed to a state where only a small number of parts are used on the sound source side by only the selection operation of the mode selection means.

And output.

In this aspect, the performance information of adjacent strings to which different control information may be given is output with different transmission channel numbers so that different effects can be applied to different parts of the external electronic musical instrument. The performance information of non-adjacent strings, to which different effects are hardly applied, is output with a different transmission channel number so as to be output by the same part of the external electronic musical instrument, so that it is less than the number of strings. Although only parts are used, rich performance expression of stringed instruments is enabled.

Another aspect is a performance information output device that receives performance information input from the outside on a plurality of reception channels and outputs the received performance information to a sound source. A reception channel number is defined in the performance information. The reception channel number includes, for example, MIDI in MIDI.

(1) represents part 1 and (2) represents part 2. In the lower half of the lower area, control change information of each part is displayed. In the case of FIG. 7, part 1,
The state of pitch bend No. 2 is displayed. Although detailed description is omitted, it is possible to finely edit each piece of performance information using a known technique.

FIG. 8 shows a working area set in the main body RAM 38. A current input mode, a selected part, a common mode or an independent mode, a later-described use number, and the like are stored by operating various buttons and sliders on the panel 40. Also, the sequencer MIDI_
The IN setting is also stored.

FIG. 9 shows details of the sequencer MIDI_IN setting. Sequencer MIDI_I
N indicates what use numbers are assigned to the 16 parts in the sound source 34, which input MIDI channels are assigned, which timbres are assigned, and how each parameter such as pan and volume is assigned. It is shown.

The use number is information for grouping a plurality of parts to be sounded based on MIDI information input via the MIDI_IN interface 28. The same use numbers are stored in the parts used by the performance information input via the MIDI_IN interface 28.

For example, when the power is turned on, M
Since the mode is the ONO mode, the use number 1 is stored in the use number column for the first to sixth parts. When any one of the input mode selection buttons 42a to 42d is operated, 1 or 0 is written in the use number of the first part to the sixth part according to the operated mode. Note that 0 indicates that the part is not used.

For example, when the mode is switched from the power-on state (MONO mode) to the two-part mode, “1” written in the use numbers of the third to sixth parts is rewritten to “0”. When the mode is changed from the two-part mode to the three-part mode, the use number 0 of the third part is rewritten to 1. In this way, the use numbers of the parts used simultaneously in one mode have the same value.

As shown in FIG. 9, parts 1 to 3
Can be used in the three-part mode, parts 4 and 5 can be used in the two-part mode, and part 6 can be used simultaneously in the POLY mode.

The input MIDI channel indicates the input MIDI channel number input to the corresponding part via the MIDI_IN interface 28. The timbre represents the name of the timbre assigned to the corresponding part, and the parameters such as pan and volume represent the contents of the parameters such as pan and volume of the corresponding part.

FIG. 10 shows a main flowchart for explaining the operation of the guitar synthesizer of this embodiment. When the power is turned on, initialization is first performed (step S30). As this initialization, for example, the contents of the main body RAM 38 are cleared, and the input mode, part selection, and the like are set to defaults.

Next, it is determined whether the part selection button 46 has been operated (step S32). When the part selection button 46 is operated, a part selection process is executed (step S34). The details of the part selection process will be described later.

If the part selection button 46 has not been operated or if the part selection processing has been performed, it is determined whether any of the input mode selection buttons 42a to 42d has been operated (step S36). If the input mode selection button has been operated, an input mode selection process is executed (step S38). The contents of the input mode selection process will also be described later.

When the input mode selection buttons are 42a to 42d
If any of the above has not been operated, or if the input mode selection processing has been performed, it is determined whether the tone color selection button 48 has been operated (step S40). When the tone color selection button 48 is operated, a tone color selection process is executed (step S42). The details of the tone color selection processing will be described later.

If the tone color selection button 48 has not been operated or if the tone color selection processing has been executed, it is determined whether the common / independent button 44 has been operated (step S4).
4). When the common / independent button 44 is operated, if the current state is the independent mode, the mode is switched to the common mode, and if the current state is the common mode, the mode is switched to the independent mode (step S46). That is, a toggle operation is performed. Subsequently, a process of displaying that the independent and common modes have been switched is performed (step S48).

If the common / independent button 44 has not been operated, or if the display processing in step S48 has been executed, it is determined whether the slider 52 has been operated (step S50). If it is determined that the slider 52 has been operated, a slider process is executed (step S5).
2). Details of the slider process will be described later.

If the operation of the slider 52 has not been performed, or after the slider processing has been executed, it is determined whether or not the sequencer control button 50 has been operated (step S54). When the sequencer control button 50 is operated, an instruction corresponding to the pressed button, for example, an instruction for recording, reproducing, rewinding, or stopping is sent to the sequencer 32 (step S56). Then, a display process is performed so as to display that the button of the sequencer 32 has been operated (step S58).

When it is determined that the sequencer control button 50 has not been operated, or after the display processing in step S58 has been executed, it is determined whether MIDI information has been input via the MIDI_IN interface 28 (step S60). .

When MIDI information is input, the M
MIDI channel information included in the IDI information is
Input MIDIc in MIDI_IN setting shown in FIG.
In the part equal to h, an instruction is given to the sequencer so as to sound the input MIDI information (step S62).

When it is determined that the MIDI information has not been input, or after the process of step S62 is completed, steps S32 to S62 are executed again.

FIG. 11 shows the details of the part selection processing. First, it is determined whether the sequencer 32 is operating, that is, whether it is being played back or being recorded (step S64). If the sequencer 32 is operating, an error message is displayed (step S66), and the part selection process ends. That is, the part is not changed during reproduction or recording.

If it is determined that the sequencer 32 is not operating, the part corresponding to the operated part selection button 46 is stored in the working area of the main body RAM 38 (step S68). Then, it is determined whether or not the use number is written in the part in the MIDI_IN setting corresponding to the stored part (step S70).
If the use number is written, the selected part has already been used, so display processing is performed (step S
72), this part selection process ends. Therefore, the part selection processing is not performed on the parts that have already been used.

If it is determined that the use number has not been written, the use numbers are written in the MIDI_IN setting from the selected part by the number of parts to be used according to the current input mode (step S74). For example, if the selected part is Part 1, the input mode is 2 parts, and the use number is 1, the use number 1 is written to Part 1 and Part 2.

Then, the use number is incremented (step S76). For example, if the current usage number is 1, the usage number is incremented to 2 and the main body RAM 3
8 is written to the working area. This is to use a different use number from the current time when the next part selection is performed. Then, the display processing in step S72 is performed, and the part selection processing ends.

FIG. 12 is a detailed flowchart of the input mode selection process. First, it is determined whether the sequencer 32 is operating (playing or recording) (step S7).
8). If it is determined that the sequencer 32 is operating, an error message is displayed (step S80)
This processing ends.

If it is determined that the sequencer 32 is not operating, it is determined whether the part currently selected by the part selection button 48 has been recorded (step S82). If it is determined that recording has been completed, an error message is displayed (step S84), and this process ends. That is, the selection of the input mode is not performed while the sequencer 32 is operating, and is not performed even when the sequencer 32 is not operating or when the selected part is already recorded.

If it is determined that the currently selected part has not been recorded, the input mode selected by operating the part selection button 48 is stored in a register in the main body RAM 38 (step S86). Next, it is determined which of the input modes is selected (step S88).

If it is determined that the mode is the MONO mode, the use number of the MIDI_IN setting is set so that the use number of the part currently selected by the operation on the part selection button is written in all six parts. In the column,
The use number is written or erased (step S9).
2). Next, input MIDI
Channels 1 to 6 are assigned (step S94). Then, this assignment state is displayed (step S96), and this input mode selection processing ends.

For example, if part 1 is selected and the use number written in the working area is (1), the use number (1) is written from part 1 to part 6 and the input MIDI ch1 is input to part 1. But part 2
, And the input MIDI channel 6 is assigned to the part 6, respectively.

When it is determined that the input mode is three parts, the MIDI_IN setting is used so that the use number of the part currently selected by operating the part selection button 46 is written in the three parts. Writing and erasing are performed in the column of numbers (step S98).

Next, among the parts in which the use numbers of the selected parts are written, the input MIDI channels 1 and 4 are allocated to the lowest numbered part, and the input MIDI channels 2 and 5 are allocated to the second part. Input MIDI channels 3 and 6 are assigned to the third part (step S100). Then, the state of the assignment is displayed (step S102), and the input mode selection process ends.

For example, assuming that part 1 is selected and the use number written in the working area is (1), the use number (1) is written in parts 1 to 3 and the input MIDI ch1 is written in part 1. , 3 are input to part 2 MIDI ch2, 4 are input to part 3
DIchs 3 and 6 are assigned respectively.

If it is determined that the mode is the two-part mode, the use number of the MIDI_IN setting is set so that the use number of the part currently selected by operating the part selection button 46 is written in the two parts. Is written or erased (step S104).

Next, of the two parts in which the use numbers of the selected parts are written, the input MIDI_ch 1, 3, 5 are assigned to the first part, and the input MIDI ch 2, 4, 6 are assigned to the second part. (Step S
106). A process for displaying the assignment state is performed (step S108), and the input mode selection process ends.

For example, if part 1 is selected and the use number written in the working area is (1), the use number (1) is written from part 1 to part 2 and the input MIDI ch1 3, 5 are
Input MIDI channels 2, 4, and 6 are assigned to part 2, respectively.

When it is determined that the input mode is the POLY mode, the use number of the currently selected part is written only in the part currently selected by operating the part selection button 46. , MIDI
Writing or erasing is performed in the column of the use number in the _IN setting (step S110).

Next, the input MID is added to the selected part.
Ich1 to Ich6 are allocated (step S11)
2). Then, a process of displaying the assignment state is performed (step S114), and the input mode selection process ends.

For example, assuming that part 1 is selected and the usage number written in the working area is (1), the usage number (1) is written only in part 1 and the input MIDI_ch1 to MIDI_ch1 to 6 are input to part 1. Assigned.

FIG. 13 is a detailed flowchart of the tone color selection process. First, it is determined whether the state of the common / independent button 44 is the common mode or the independent mode (step S116). If it is determined that the current mode is the common mode, all parts in which the same use number as that of the part currently selected by the operation of the part selection button 46 is written are selected by the operation of the tone selection button 48. Is set to the present tone color, and this tone color information is sent to the sequencer (step S118). Then, a process for displaying this state is performed (step S120), and the tone color selection process is terminated.

If it is determined that the mode is the independent mode, the tone selected by the operation of the tone selection button 48 is set to only the part currently selected by the operation of the part selection button 46, and this tone color information is stored in the sequencer. 32 (step S122), a process of displaying the tone color selection state is performed (step S124), and the tone color selection process ends.

FIG. 14 is a detailed flowchart of the slider operation process. First, it is determined whether the state of the common / independent button 44 is the common mode or the independent mode (step S126). If it is determined that the mode is the common mode, the parameter corresponding to the operated slider 52 is assigned to all the parts in which the same use number as that of the part currently selected by the operation of the part selection button 46 is written. The setting is made (step S128), and this tone color selection processing is terminated.

If it is determined that the mode is the independent mode, the parameter value corresponding to the operated slider 52 is set only for the part currently selected by operating the part selection button 46 (step S130), and this tone color is set. The selection processing ends.

In the guitar synthesizer of this embodiment, the MIDI information from the performance section 22 is described as being recorded in any of the initially selected MONO, three-part, two-part, and POLY modes. Is MO

The IDI information may be determined in advance so as to be output as performance information of part 2. Similarly, only the three-part mode may be provided. For example, the input MIDI channels 1 and 4 are input MIDI channels 2 and
5 is an input MIDI channel as MIDI information of part 2
Items 3 and 6 may be determined in advance so as to be output as MIDI information of part 3. In the above embodiment, the performance information is generated by the sound source using the MIDI information. However, if the musical information can be generated by a plurality of parts,
It may be information instead of MIDI information.

[0107]

According to the first aspect of the present invention, the performance information of adjacent strings to which different control information can be given is output to different parts so that different effects can be applied, and the different effects are output. Since the performance information of non-adjacent strings that are rarely applied is output to the same part, it is possible to express the performance of a stringed musical instrument even though only fewer parts are used than the number of strings.

According to the second aspect of the present invention, even if the performance information is not changed on the external performance information source side, the performance of the adjacent performance information source to which different control information may be given on the sound source side. The information is output to different parts, and the performance information of non-adjacent performance information sources to which different control information is not given is output to the same part. Can be realized.

According to the third aspect of the invention, when the first mode is selected, a so-called MONO mode is set,
When the second mode is selected, performance information from non-adjacent strings is output to the same part, and performance information from adjacent strings is output to different parts. Therefore,
By simply selecting the mode selecting means, it is possible to automatically switch from the MONO mode to a state in which the performance expression of the stringed instrument can be performed even though only a few parts are used.

According to the fourth aspect of the present invention, when the first mode is selected, the sound source side is set to a state corresponding to the so-called MONO mode. When the second mode is selected, the first performance information from the non-adjacent performance information source is output to the same part, and the first performance information from the adjacent performance information source is output to a different part. To be in the sound source side. Therefore, by using only the selection operation of the mode selection means, even when only a small number of parts are used on the sound source side, for example, the performance expression of a stringed instrument can be automatically performed.

According to the fifth aspect of the present invention, the performance information of adjacent strings to which different control information may be given is connected to the outside by assigning different transmission channel numbers so that different effects can be applied. Since the performance information of non-adjacent strings, which are hardly affected by different effects, are transmitted to the externally connected electronic musical instrument, the same transmission channel number is assigned to the externally connected electronic musical instrument. In an electronic musical instrument, a rich performance expression of a stringed musical instrument can be achieved by using only a smaller number of parts than the number of strings.

According to the sixth aspect of the present invention, the performance information to which adjacent reception channel numbers are assigned is transmitted to different parts of a sound source so that different effects can be applied, and non-adjacent reception channel numbers are transmitted. Since the attached performance information is output to the same part of the sound source, rich performance expression of, for example, a stringed instrument can be performed without using a small number of parts in the sound source.
