Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a musical sound performance apparatus capable of appropriately assigning “insertion effects” that individually apply effects to a plurality of performance parts and effectively utilizing effect resources.
[0002]
[Prior art]
Conventionally, there are electronic musical instruments in which the keyboard can be divided into two areas, and different effects can be set with different tones for each area. For example, the left hand area is made the organ tone, and the right hand area It is also possible to make the sound of a piano. Furthermore, only in the right-hand side area, there are some which can set two timbres and respective effects for each timbre, and in this case, for example, when a certain key is struck, the two timbres are sounded so that they can be heard. be able to.
[0003]
This type of electronic musical instrument has a mixer input such as distortion (waveform distortion effect) and tremolo in addition to system effects applied to multiple parts input to the mixer, such as reverb and chorus effects. An insertion effect function for applying an individual effect to a single part is provided in advance, and a DSP (Digital Signal Processor) is provided to add such an insertion effect to a musical sound. . In addition, for example, song data can be recorded on 16 tracks 1 to 16 (referred to as “song recording”), or song data recorded in advance on tracks 1 to 16 can be automatically played. You can also join the performance on the keyboard.
[0004]
Now, three effect giving means DSP1 to DSP3 are prepared for the insertion effect. The area where the keyboard is divided is called “key range” and the pronunciation corresponding to the left (hand) side key range is “part”. If the first and second pronunciations corresponding to the right (hand) side healthy area are called “part R1” and “part R2”, the electronic musical instrument has 16 records in these three parts. A total of 19 parts of music signals can be handled by adding tracks. In this case, timbre and effect imparting means (DSP) can be individually assigned to part R1, part R2 and part L, so that the keyboard can be played and recorded on three tracks at the same time. it can.
[0005]
In a conventional apparatus, the DSP is set according to the setting flow for each part. For example, when the user designates part R1 on the operation panel and selects a timbre corresponding to this part, the DSP for adding an effect that matches the selected timbre is automatically turned on. (Note that the user does not need to set the DSP number and the type of effect using the DSP, but these settings can be changed by the user later on the detailed screen. This change operation is troublesome and basically uses the one set with the tone.) Here, the DSP to be used is set corresponding to the part (R1 etc.), for example, , “Use DSP1 for part R1” and the like, the correspondence between the part and the DSP is determined in advance as a standard.
[0006]
When the tone color is set for the part (R1 or the like) in this way, the user can perform using the keyboard in which the DSP is set for the part, and can record (record) the performance content. Furthermore, the user can reproduce the recording, and when reproducing, the DSP used at the time of recording is automatically selected and set to reproduce the performance.
[0007]
Here, when an automatic performance is performed by playback, the user's recorded keyboard is used (in this case, the tone settings and effect settings are usually different, but the same may be used). The use of the DSP is batting between the performance and the hand-playing performance (keyboard R1). In this case, the DSP is not adopted for the hand-playing performance (part R1). There will be a situation of disappearing.
[0008]
In addition, the DSPs provided for the other parts R2 and L are dedicated to the parts R2 and L in the standard DSP assignment setting, so these DSPs are used for the performance of the parts R2 and L. Even if it is not, it is not used for Part R1, and this means that DSP resources of the electronic musical instrument are not effectively used.
[0009]
According to another conventional method, the DSP (1-3) to be used is set for each keyboard part (R1, R2, L) or for each track (1-16) of song data, and what kind of effect addition processing is performed. Some DSPs are set as to whether or not to perform this. For example, when DSPs 1, 2, and 3 are assigned to the parts R1, R2, and L, the contents of effect processing (effect types) can be set for each of the DSPs 1 to 3 corresponding to the parts.
[0010]
However, when the same DSP is designated in such a setting, the DSP setting is changed with priority on the last arrival. Or, the keyboard (key range) part] may no longer be added by the DSP. For example, even if it is set to apply distortion by hand-playing, if it is set to have a distortion effect for automatic performance playback, the distortion may not be applied to hand-playing. .
[0011]
If there are three insertion effect DSPs 1 to 3 as described above, DSP1 is set for part R1, and DSP1 is set for part R2 and track 1 as well. In spite of the fact that the DSPs 2 and 3 are not used, only the part R1, R2 and the track 1 that has been instructed to set the last arrival can only be used with the DSP. is there.
[0012]

[Means for Solving the Problems]
According to the main feature of the present invention, a musical sound that generates musical performance signals by processing musical sound signals belonging to a plurality of performance parts (parts R1, R2, L, tracks 1 to 16) (n: for example, n = “19”). In the performance device, a plurality of (N) are provided to give individual effects (insertion effects) for each musical tone signal of each performance part (R1, R2, L, 1 to 16). : N = “3”) effect applying means (DSP 1 to 3), wherein the number of effect applying means (N) is less than the number of performance parts (n) (N <n), one effect applying means Overlap determination means (FIG. 9: Q4) for determining whether the designation or assignment of the same effect imparting means overlaps among a plurality of performance parts, and the overlap determination means. By means (Q4) In response to the determination of overlapping of the same effect providing means (Q4 → YES), unassigned search means (FIG. 11: Q54) for searching for other effect assigning means that have not been specified or assigned yet, In response to the fact that no other effect imparting means has been searched by the assignment search means (Q54) (Q54 → NO), all of the effects are assigned based on the predetermined effect assigning means allocation priority (FIG. 12: Tables 1, 2,...). Reviewing the designation or assignment of the effect imparting means (DSP1 to DSP3) for the performance parts (R1, R2, L, 1 to 16) (FIG. 12: review target 2) and the designation or assignment changing means (FIG. 11: Q56) A musical tone performance device is provided. Note that parentheses indicate reference symbols, terms, locations, and the like of the corresponding embodiments, and the same applies to the following.
[0014]
In addition, the musical tone performance apparatus according to the present invention is further adapted to a predetermined priority order for assigning the effect applying means (Q4 → YES) when the overlap determining means (Q4) determines that the same effect applying means overlaps (Q4 → YES). 12: Based on the tables 1, 2,...), The designation or assignment to the corresponding performance part is reviewed for the same effect imparting means for which the overlap has been determined (FIG. 12: review object 1) second designation or assignment changing means ( FIG. 11: Q53) can be provided.
[0015]
Furthermore, in the musical tone performance apparatus of the present invention, the effect assigning means allocation priority order can be arbitrarily set by the user (FIG. 6: P26) [Claim 3].
[0016]
Note that the priority order for assigning effect means is based on the performance part, based on the timbre applied to the performance part, based on the order in which the effect imparting means is specified for the performance part, or on the performance The timbre set for the part, the performance part, or a combination thereof can be used as a reference.
[0017]
[Effects of the Invention]
The musical tone performance apparatus (all claims) according to the present invention processes musical tone signals belonging to a plurality of (n: for example, n = “19”) performance parts (parts R1, R2, L, tracks 1-16, etc.). In a musical tone performance apparatus that generates performance signals, a plurality of (N: for example, N = “3”) effect imparting means (DSP: DSP :) for imparting individual effects (insertion effects) for each musical tone signal of each performance part. DSPs 1 to 3) are provided, and the contents of individual effects by each effect imparting means can be individually set, and any one of the effect imparting means can be assigned to each performance part. The effect imparting means (DSP 1 to 3) for adding an effect to the musical sound can individually set the effect according to the performance part, but the number (N) of effect imparting means is smaller than the number (n) of the performance parts. In spite of (N <n), according to the present invention, it is possible to effectively assign the effect imparting means to the performance part, and to effectively use the effect resource during the performance.
[0018]
More specifically, according to the main feature of the present invention (Claim 1), when assigning the effect imparting means to the performance parts, when the designation or assignment of the same effect imparting means overlaps among a plurality of performance parts [ FIG. 9: Q4 (YES) → Q5 (FIG. 11)], searching for another effect imparting means that has not yet been specified or assigned (FIG. 11: Q54), and when no other effect imparting means has been searched [Q54 (NO) → Q56], on the basis of a predetermined priority order for assigning effect assigning means (FIG. 12: Tables 1, 2,...), The designation or assignment of effect assigning means for all performance parts is reviewed (FIG. 11: Q56, FIG. 12: Review object 2). That is, when there are performance parts that overlap with the effect applying means, it is checked whether there is any other available effect applying means, and if there is no empty effect applying means, all performance parts (R1, R1) according to a predetermined priority order. The setting of the effect applying means (DSP 1 to 3) of R2, L, 1 to 16) is reviewed.
[0019]
For example, a performance part in which specified effect applying means overlaps with another performance part that has already been set with another effect applying means effect device, and assigning the effect applying means to a performance part with a higher priority. (In this case, it is possible to stop the use of the effect assigning means already assigned to performance parts other than the overlapping performance parts and newly assign them to other performance parts). Therefore, according to the present invention, it is possible to automatically assign appropriate effect applying means balanced in all performance parts.
[0020]
In the musical tone performance apparatus of the present invention (Claim 2), when it is determined that the same effect applying means overlaps among a plurality of performance parts (FIG. 11: Q4 → YES), a predetermined effect applying means allocation priority order is determined. Based on (FIG. 12: Tables 1, 2,...), The designation or assignment to the corresponding performance part is reviewed for the same effect imparting means for which the overlap has been determined. For example, the effect priority means assignment priority of “last arrival priority” = “Table 1” is selected, and the effect part DSP1 and DSP3 are assigned to the performance part = part R1, and the effect is applied to the performance part = track 5. When an instruction to set the granting unit DSP1 is given, the allocation of the effect granting unit DSP1 overlapping between the performance parts R1 and 5 is reviewed according to the review mode of “review target 1”, and the priority order of “table 1” Thus, the effect assigning means DSP1 is preferentially assigned to the last performance part 5 (the use of the effect giving means DSP1 is stopped for the performance part R1). Therefore, according to the present invention, when there is an overlap of the same effect applying means among a plurality of performance parts, it is possible to automatically assign effect applying means according to a predetermined priority order.
[0021]
In the musical tone performance device according to the present invention (claim 3), the priority order for assigning effect assigning means can be arbitrarily set by the user (FIG. 6: S26). For example, the user can create a priority order arbitrarily using a priority order creation screen or the like, or the user can set any priority order from a plurality of priorities prepared in advance. It is said. Therefore, according to the present invention, when there is no vacancy in the effect imparting means or when the same effect imparting means overlaps among a plurality of performance parts, the effect imparting means according to the priority according to the user's preference. Can be assigned automatically.
[0022]
Note that the priority order for assigning effects is applied to performance parts such as keyboard parts (R1, R2, L) and music data tracks (1 to 16) as necessary, and to performance parts as necessary. Are based on the order in which the effect imparting means is specified for the performance part (first-come-first-served or second-lasted), or those based on a combination thereof. Therefore, by making it possible for the user to set the effect assignment means assignment priority order as described above, it is possible to adopt a priority order that meets various needs in the insertion effect setting.

[0047]
[Main processing]
FIG. 3 is a flowchart of the main process representing the entire process of the musical tone performance control program having the insertion effect setting function according to one embodiment of the present invention. In the first step S1, execution of a predetermined program is started by turning on the power, the contents of the RAM 2 are cleared, and initial settings are made to initialize the system. In the next step S2, panel setting processing is performed, the operation status of the panel operator MN is received, and various settings of devices and modes, static settings of insertion effects, and the like are executed.
[0048]
Subsequently, in step S3, a performance instruction is detected, a performance signal is generated, and an insertion effect is statically set. For example, the musical tone signal instructed by the performer is processed by the performance operators 5 to 7 such as the keyboard KB incorporated in the system, or the music data of the automatic performance is read from the storage device such as the ROM 3 or the external storage device 14. A performance signal transmitted from the external device 16 is received, and a performance signal composed of a performance instruction signal and an effect instruction signal is generated.
[0049]
In the next step S4, a performance signal is generated from the performance and effect instruction signal generated in step S3, amplified by an amplifier, and output from the speaker SP. Then, in the final step S5, other processing (other processing necessary for desired operation of the system) is performed, and the processing in steps S2 to S5 is repeatedly executed until an instruction to end the main processing is given.
[0050]
[Panel setting process 1]
4 to 6 are flowcharts showing “panel setting process 1” (first embodiment) which is an example of the panel setting process in step S2 of the main process. In the “panel setting process 1”, various settings are performed based on the operation of the panel operator MN of the setting operator device 8. In the first step P1 of this processing flow, it is determined whether or not the panel operation element MN has been operated and a setting input has been made. If no panel setting has been input, the process returns to step S3 of the main process (FIG. 3). When any panel operation element MN is operated, a panel setting flow after step P2 for changing the existing setting is entered.
[0051]
In step P2, it is determined whether or not the operated switch is an “effect” button related to the setting of the insertion effect. When the “effect” button is operated, in step P3, the performance part and effect applying means are determined. The “part / DSP correspondence setting process” (FIG. 7) is executed to associate (DSP). Then, when the processing routine of step P3 is completed, the process goes to step P4.
[0052]
In step P4, the part / DSP allocation setting screen is displayed on the display DP of the display device 9 to allow the user to select an arbitrary DSP. Therefore, the user can arbitrarily select how to assign the effect applying means DSP1, DSP2, DSP3 to the parts R1, R2, L, etc. using this screen. In the next step P5, the selection state of the DSP by the user is accepted, and this DSP selection state is set in the system. When setting a DSP, it is not possible to select a DSP that has been set so that the one that is to be set later does not set the same DSP as that previously set. .
[0053]
In the next step P6, it is determined whether or not the “NEXT” button has been pressed. While the “NEXT” button has not been operated, the process returns to step P4, and the above-described DSP selection operation continues until the “NEXT” button is pressed. can do. When the “NEXT” button is pressed, the process proceeds to step P7.
[0054]
In step P7, a menu screen regarding the type (type) of the effect (insertion effect) is displayed on the display DP, and the user is allowed to select the effect type (insertion effect type). This effect type includes, for example, “rotary speakers 1 to 6” for variously simulating rotating speakers such as organs, “tremolo 1 to 3” for periodically changing the sound volume periodically, and moving the sound image localization periodically. There are “Auto Pan 1 and 2”, “Distortion 1 to 4” that give various distortions to the sound of a guitar or the like.
[0055]
In the next step P8, the effect type selection state by the user is accepted, and this effect type selection state is set in the system. Subsequently, in step P9, it is determined whether or not the “NEXT” button has been pressed. While the “NEXT” button is not operated, the process returns to step P7 to continue the effect type selection work. When the “NEXT” button is pressed, the process proceeds to Step P10 (FIG. 5).
[0056]
In step P10, an effect (insertion effect) application setting screen is displayed on the display DP, and the effect application to the user (for example, the ratio of the wet sound with effect to the original dry sound without effect). (Numeric value to be expressed) is selected. In the next step P11, the degree of effect input by the user is received, this degree of application is set in the system, and then the process returns to step S3 of the main process (FIG. 3).
[0057]
When it is determined in step P2 (FIG. 4) that the operated switch is not the “effect” button, the process goes to step P12 (FIG. 5), and whether or not the “VOICE L” button on the operation panel has been pressed. Determine whether. Here, when it is detected that the “VOICE L” button has been pressed (YES), the process proceeds to Step P13, where the timbre setting screen for part L is displayed on the display DP, and the user selects the timbre for part L. . In the next step P14, the input of the timbre selected by the user to part L is accepted, and after this timbre is set in the system, the process returns to step S3 of the main process (FIG. 3).
[0058]
If a negative determination is made in step P12 (NO), the process proceeds to step P15, and it is determined whether or not the “VOICE R1” button on the operation panel has been pressed. If it is detected that the “VOICE R1” button has been pressed (YES), the process proceeds to step P16, and the tone color setting screen for part R1 is displayed on the display DP. In step P17, a timbre selection input from the user for part R1 is received and the selected timbre is set. Then, the process returns to step S3 of the main process.
[0059]
When a negative determination is made in step P15 (NO), the process proceeds to step P18, and it is determined whether or not the “VOICE R2” button on the operation panel has been pressed. If it is detected that the “VOICE R2” button has been pressed (YES), the process proceeds to step P19, and the tone color setting screen for part R2 is displayed on the display DP. In step P20, a timbre selection input from the user is received, the received timbre is set for part R2, and then the process returns to step S3 of the main process.
[0060]
If a negative determination is made in step P18 (NO), the process proceeds to step P21 (FIG. 6), and it is determined whether or not the “area division on / off” switch on the operation panel has been pressed. If it is detected that the “area division on / off” switch has been pressed (YES), the process proceeds to step P22, and further, it is determined whether or not the current mode is “key area division on”. To do. If it is currently in the key range division on mode, the system operation mode is set to “area division off” in step P23. If it is not the key range division on mode, the system operation mode is set to “ Set to “Region division on”. Then, after the processes of Steps P23 and P24, the process returns to Step S3 of the main process.
[0061]
If a negative determination is made in step P21 (NO), the process proceeds to step P25, and among the operation elements MN on the operation panel, panel operation elements related to the automatic performance setting instruction (instructions for setting, playing, and stopping performance music). It is determined whether or not there has been an input from an operator or the like, and if it is not an instruction setting for automatic performance (NO), the process goes to Step P26. In step P26, the instruction received by the operation of the other panel operators other than the panel operators described above is executed among the panel operators MN. Here, for example, in addition to the setting relating to automatic accompaniment, the user can change the setting state of “DSP allocation priority table” and “DSP allocation review target”. In this setting change, not only “table” and “review target” can be selected, but also these contents can be modified or newly created. After the process of step P26, the process returns to step S3 of the main process.
[0062]
When an affirmative determination is made in step P25 (YES), the process proceeds to step P27, where it is determined whether or not the panel operation is a performance song setting, and when the input is related to the automatic performance song setting. (YES), go to Step P28, display the song data title on the display DP and let the user select the song data, and in the subsequent Step P29, the selection of the song data by the user is accepted. In the next step P30, the selected music data is read from the storage device such as the ROM 3 or the external storage device 14 and set on the RAM 2, and then the process returns to step S3 of the main process.
[0063]
On the other hand, if it is determined in step P27 that the performance music is not set (NO), it is determined in step P31 whether or not the panel operation is a reproduction instruction. Here, when the operation input is a reproduction instruction, the process proceeds to step P32 to perform reproduction start processing, and the set music data is read to start automatic performance. If it is not a playback instruction, the process proceeds to step P33, where it is determined whether or not the panel operation is a stop instruction. If it is a stop instruction, the automatic performance being played back is stopped in step P34. In step P35, other instructions relating to automatic performance are received and the corresponding processing is executed. Other instructions in step P35 include instructions such as temporary stop, postponement, and return. In addition, after the process of step P32, P34, P35, it returns to step S3 of the main process.
[0064]
[Part / DSP compatible setting process]
FIG. 7 is a flowchart showing a part / DSP correspondence setting process routine executed in step P3 (FIG. 4) of "panel setting process 1" according to the first embodiment of the present invention. This processing routine involves static setting of the insertion effect DSP for parts R1, R2, and L (including song recording). In the first step P51, the setting state of the effect applying means (DSP) for the performance part is displayed on the display DP. For example, as shown in FIG. 8A, the DSP setting state is displayed corresponding to each part.
[0065]
In the example of FIG. 8A, how the DSPs 1 to 3 are set for the parts R1, R2, and L is displayed. That is, “DSP1 → DSP3” is displayed corresponding to part R1, two DSPs are set in part R1, and insertion effects are added to the musical sound signal of part R1 in the order of DSP1 and DSP3. It is shown that. On the other hand, the other parts R2 and L indicate that the insertion effect is not set or is not applied.
[0066]
Subsequently, in step P52, the user selectively designates a part to be DSP-set among the parts R1, R2, and L, and accepts this part designation. In the next step P53, a DSP setting screen for the specified part is displayed on the display DP, and the user is allowed to specify the DSP. For example, FIG. 8 (2) is an example of a DSP setting screen when the part R2 is selected and specified, and FIGS. 8 (3A) and (3B) are examples of the DSP setting screen when the part R1 is selected and specified. Show.
[0067]
In the screen example of FIG. 8 (2), the only available DSP for the insertion effect is “DSP2,” and the setting candidate display field on the right side displays a DSP that can be set for part R2. Since only “DSP2” is displayed, the user can select “DSP2” designated by the cursor (hatched frame). When the user selects “DSP2” (“OK” button operation), “DSP2” is displayed in the set display column on the left side where the DSP set for part R2 is displayed (not shown). ).
[0068]
In the screen example of FIG. 8 (3A), “DSP1” and “DSP3” set for the part R1 are displayed in the set display column. By instructing this set display column (“BACK” button), and further designating the cancellation of “DSP3” displayed in the set display column (number “2” and “decision” button), “ The setting of “DSP3” can be canceled. Thereby, the setting screen becomes a screen as shown in FIG. 8 (3B).
[0069]
As shown in the screen of FIG. 8 (3B), the instruction is moved to the setting candidate display column on the right side (“NEXT” button), and “DSP2” displayed in the setting candidate display column is selected as described above. Then (numeral “1” button) can be additionally reset to part R1 by designating it as the DSP of part R1 (“decision” button). When “DSP2” is designated as the DSP of part R1, the display of “DSP2” moves to the set display column on the left (not shown).
[0070]
In the next step P54, designation of DSP setting, setting cancellation and resetting performed by the user in this way is accepted, and in the subsequent step P55, the DSP designated to the designated part is assigned and set. Then, in the next step P56, it is determined whether or not the “NEXT” button has been pressed. While the “NEXT” button is not operated, the process returns to step P51 to continue the part and DSP designation work, and the next part. You can modify settings and settings. When the “NEXT” button is input, the process exits the part / DSP correspondence setting process and returns to step P4 (FIG. 4).
[0071]
[Performance instruction detection and performance signal generation processing]
9 and 10 are flowcharts showing an example of performance instruction detection and performance signal generation processing in step S3 of the main processing. In the “performance instruction detection and performance signal generation setting process”, a performance instruction such as a performance instruction signal or an effect instruction signal is generated by detecting a performance instruction based on a performance operation or automatic performance. In the first step Q1 of this processing flow, it is determined whether or not automatic performance reproduction is in progress. If the performance is being performed [when reproduction execution is instructed in steps P31 and P32 (FIG. 6)], the process goes to step Q2, and subsequently, the music data set in the RAM 2 (step P30) is read out.
[0072]
In the next step Q3, it is determined whether or not there is DSP number designation data for designating the number (DSP1 to DSP3) of the effect imparting means (DSP) in the read music data, and the DSP number designation data. , The process goes to step Q4 to check whether a DSP having the same number has already been set (whether the DSP set in the music data is a DSP already used). In other words, the DSP for the insertion effect includes a plurality of DSPs such as DSP1, DSP2, and DSP3. However, when there is DSP number designation data, the DSP having the same number has already been changed in step Q4. It is determined whether the track or keyboard is set.
[0073]
Here, if the DSP of the read music data is a DSP that has already been set, the process proceeds to “DSP allocation processing” (FIG. 11) in step Q5, and a predetermined priority order, review target, etc. After allocating the DSP according to the rules, the process proceeds to step Q6. If the DSP of the music data is not yet set, automatic setting is performed so that the music data is used for effect processing on the track, and the process proceeds to step Q6.
[0074]
In step Q6, performance signals such as performance instruction signals and effect instruction signals corresponding to the read music data and DSP settings are generated. The performance signal generated here is converted into a musical tone signal and subjected to sound generation processing in step S4 of the main processing flow (FIG. 3). Then, after the process of step Q6 and when it is determined that the automatic performance is not performed in step Q1, the process goes to step Q7.
[0075]
In step Q7, it is determined whether or not a performance operator has been input. If any performance operator has been input, the process goes to step Q8 (FIG. 10) to enter hand-playing processing. If there is no performance operation input, the process returns to step S4 of the main process flow (FIG. 3).
[0076]
In step Q8, it is checked whether or not the input of the performance operator is key-on (key depression). If it is key-on (YES), in step Q9, the area division mode is the area division on. Then, it is determined whether or not the key is input from the keyboard KBL (5) in the left key range. Here, when the key is input from the left keyboard keyboard KBL (5), the tone and DSP assigned to part L are set in step Q10, and if not, the process goes to step Q11 and part R1. , R2 tones and DSP are set.
[0077]
That is, in steps Q10 and Q11, the mode state set by the user in step P24 (FIG. 6) of the panel setting process 1 is determined, and the setting is made by looking at the setting of the keyboard KB for which the key-on instruction has been given. Set the tone and DSP (effect device) according to the sound. After the processing in steps Q10 and Q11, in step Q12, based on the set tone color and DSP, a performance signal (performance instruction signal and effect instruction signal) is generated so that the performance sound is generated by the tone color and DSP. To do. Then, the process returns to step S4 of the main process.
[0078]
For example, when the key-on key belongs to the left key range KBL (5) in the mode state set to “key range division on”, in step Q10, step P14 of the panel setting process 1 is performed. The timbre of part L set by the user in FIG. 5 and the DSP effect set in steps P3 to P11 are set, the corresponding performance signal is generated in step Q12, and the sound is produced with these timbres and effects. The performance sound signal is processed as described above.
[0079]
Also, in the “key division on” mode, when key-on is input from the right keyboard keyboard KBR (6), or when the “key division off” mode is set, In step Q11, the timbre of parts R1 and R2 set by the user in steps P17 and P20 (FIG. 5) of the panel setting process 1 and the DSP effect set in steps P3 to P11 are set, and corresponding in step Q12. A performance signal is generated, and the performance sound signal is processed and produced with these timbres and effects.
[0080]
On the other hand, if the determination in step Q8 is negative rather than key-on (NO), the process proceeds to step Q13, and it is further checked whether or not the input of the performance operator is key-off (key release). If the input signal is a released signal, in step Q14, a process for stopping the corresponding tone signal being generated is executed. If it is not a key-off input but an input from another performance operator, a performance instruction signal corresponding to an instruction from another performance operator such as a sustain pedal or pitch bend is generated in step Q15. Then, after the processes of steps Q14 and Q15, the process returns to step S4 (FIG. 3) of the main process.
[0081]
[DSP allocation processing]
FIG. 11 is a flowchart showing a DSP allocation processing routine executed in step Q5 (FIG. 9) of "performance instruction detection and performance signal generation processing" according to one embodiment of the present invention. This processing routine is related to the dynamic setting of the insertion effect DSP. In the first step Q51, the “DSP allocation priority table” is read.
[0082]
In the next step Q52, based on the “DSP allocation priority table” read in step Q51, the DSP processing priority already set (of the song data read in step Q2) has already been set. It is determined whether it is higher than the processing priority. If the priority of the current DSP instruction is high by comparing both ranks, the process goes to step Q53, and DSP allocation is performed according to the currently set “DSP allocation priority table” and “DSP allocation review target (mode)”. Perform the change process.
[0083]
FIG. 12 shows a list example (upper part) of “DSP allocation priority table” and a list example (lower part) of “DSP allocation review target (mode)” used in the DSP allocation change at step Q53 and the like. A plurality of these “DSP allocation priority table” and “DSP allocation review target” are prepared in the ROM 3 or the external storage device 14 of this musical tone performance system, and which table or review target is adopted for DSP allocation. In step P26 (FIG. 6) of the panel setting process 1, it is possible to arbitrarily select and set by operating the panel operator MN. In addition, the contents of these tables and review targets can be corrected or newly created by the user.
[0084]
In the “priority table” list in FIG. 12 (upper part), “table 1” to “table 7” and the like are illustrated, and in the “review target” list in FIG. 12 (lower part), only the overlapping DSPs are allocated. “Review target 1” (review mode 1) to be reviewed, “Review target 2” (review mode 2) to review the allocation of DSPs set for all parts and all tracks, and the like are illustrated. Note that which of these “tables” and “reviewed objects” to use for DSP allocation can be set in advance by the user as described above, but if not set by the user, A general one (for example, “table 1” or “review target 1”) set in advance as a default is used for DSP allocation.
[0085]
Here, each table in FIG. 12 (upper part) will be described briefly. “Table 1” is a priority for later arrival, that is, the insertion effect DSP is dynamically assigned with priority on the setting of the latest received DSP. This is what you want to set. For example, when “table 1” and “review target 1” are selected, DSP 1 and “DSP 3” are assigned to part R1, and “DSP 1 is set for track 5 of automatic performance music data”. When the number designation data is received, the use of DSP1 is stopped for part R1, and only DSP3 is used, and DSP1 is used for track 5. In other words, according to the review mode of “review target 1”, the allocation of DSP1 overlapping between part R1 and track 5 is reviewed, and DSP1 is the latest (later arrival) song data track 5 according to the priority order of “table 1”. Is assigned a priority.
[0086]
Next, “table 2” is, in contrast to “table 1”, all items are set in order of speed so that those set first are prioritized and those set later are excluded. “Table 3” is a table in which priorities are assigned to the keyboard parts (R1, R2, L) and tracks (1 to 16), and in the case of overlapping, those with lower priorities are transferred. . “Table 4” gives priority to performance parts (R1, R2, L, etc.) and tones (guitar tone, violin tone,...). In the illustrated example, basically, the parts (R1, R2, L) are given priority, and the priority order of the timbres is subsequently determined.
[0087]
“Table 5” is a table in which the priority order is determined only by the timbre. In “Table 6”, the performance parts (R1, R2, L, etc.) are given priority first, followed by the one set later, and in “Table 7”, the basic ones are given priority. In addition, the performance parts (R1, R2, L, etc.) are given priority, followed by the previously set one.
[0088]
Now, after such an assignment (allocation) change process of step Q53, and when it is determined in step Q52 that the priority of the current DSP instruction is not high, the process proceeds to step Q54. In step Q54, whether there is a vacancy in other DSPs, that is, whether there are DSPs for which performance parts such as keyboard parts (R1, R2, L) and music data tracks (1-16) are not set. Inspect. If there is a vacant (unset DSP), in step Q55, the unset DSP is assigned to a performance part with a low priority that has not been able to be assigned a DSP in the process so far. If there is no free space (unset DSP), DSP allocation to the performance part is invalidated in step Q56.
[0089]
In step Q56, “Reviewing DSP allocation across all parts and tracks” in “Review object 2” (lower part of FIG. 12) is applied, and the currently set priority processing table (FIG. 12) is referred to. DSP allocation can be changed. That is, when overlapping parts appear [Step Q4 = YES (FIG. 9)], it is checked whether there is any other free DSP (effect providing means) (Step Q54). Q54 = YES), in step Q56, the DSP settings of all parts are reviewed according to the priority order of the priority processing table.
[0090]
For example, the “song data track” read in step Q2 (this performance part is overlapped with “other performance part” and the DSP is low in priority), and another DSP is already set. The “other performance parts” are compared, and the DSP is assigned to the higher priority part. In this case, among the performance parts with lower priority than the “other performance parts” where the DSP overlaps, the performance parts with lower priority (for example, “other performance parts”) are assigned. It is also possible that the DSP is stopped and the DSP is assigned to a performance part (for example, “music data track”) having a higher priority than the DSP.
[0091]
After the processes of steps Q55 and Q56, the process returns to step Q6 (FIG. 9) of the performance instruction detection and performance signal generation process. When the allocation change process in step Q53 or the allocation change process by reviewing all performance parts is performed in step Q56, when the DSP assignment is changed, the effect applied to the DSP according to the change is made. The (insertion effect) is also automatically changed to the contents set corresponding to the performance part to which the DSP is assigned by changing.
[0092]
FIGS. 13 to 15 are flowcharts showing “panel setting process 2” (second embodiment), which is another example of the panel setting process in step S2 of the main process. In this “panel setting process 2”, the insertion effect setting procedure for the DSP in steps P2 to P11 of “panel setting process 1” (FIGS. 4 to 6) is eliminated, and instead of this, a setting sequence for each performance part is set. An “effect setting process” is newly inserted into P12 to P14, P15 to P17, and P18 to P20. That is, in the “panel setting process 2”, as shown in FIGS. 13 to 15, the setting series R2 to R5, R6 to R9, and R10 to R13 for each performance part are shown in FIGS. "Effect setting process" is included as steps R5, R9, and R13.
[0093]
That is, in the “panel setting process 2”, the “effect setting process” (steps R5, R9, R13: FIGS. 16 and 17) is executed for each performance part setting series R2 to R5, R6 to R9, and R10 to R13. Thus, when setting the insertion effect based on the operation of the panel operator MN of the setting operator device 8, the user merely selects the “DSP control” switch (not shown) of the setting operator MN. The setting operation is completed without being aware of a plurality of effect imparting processing blocks (effect imparting means) such as DSP1 to DSP3, and the system side automatically assigns them to DSP1, DSP2 or DSP3 thereafter. There is.
[0094]
In the first step R1 of this process flow (corresponding to step P1 (FIG. 4) of “panel setting process 1”), it is determined whether the panel operator MN has been operated and a setting input has been made, and panel setting has been made. If there is no input, the process returns to step S3 of the main process (FIG. 3). When any panel operation element MN is operated, a panel setting flow after step R2 for changing the existing setting is entered.
[0095]
If it is determined in step R2 [corresponding to step P12 (FIG. 5)] that the “VOICE L” button on the operation panel is pressed (YES), step R3 [corresponding to step P13] is determined. ], The timbre setting screen of part L is displayed on the display DP of the display device 9 to allow the user to select the timbre of part L, and in the next step R4 (corresponding to step P14), the part L is selected by the user. After receiving the inputted tone color and setting the tone color in the system, the routine proceeds to the “effect setting process” routine (FIGS. 16 and 17) in step R5.
[0096]
In step R2, a negative determination is made that the "VOICE L" button is not pressed (NO). Further, in the determination block for pressing the "VOICE1" button in step R6 (corresponding to step P15), the "VOICE R1" button is If it is detected that the button is pressed (YES), the process proceeds to Step R7 (corresponding to Step P16). In step R7, the timbre setting screen for part R1 is displayed, and in step R8 (corresponding to step P17), the timbre selection input from the user to part R1 is received and the selected timbre is set. Then, the process proceeds to the “effect setting process” routine (FIGS. 16 and 17) in step R9.
[0097]
In step R6, a negative determination is made that the “VOICE R1” button is not pressed (NO), and in the determination block for the “VOICE R2” button press in step R10 (FIG. 14) (corresponding to step P18), “VOICE R2” is determined. When it is detected that the "" button has been pressed (YES), the process proceeds to Step R11 (corresponding to Step P19). In step R11, the tone color setting screen for part R2 is displayed. In step R12 (corresponding to step P20), a timbre selection input from the user is accepted and the received timbre is set in part R2. Then, the process proceeds to the “effect setting process” routine (FIGS. 16 and 17) in step R13. .
[0098]
Note that after the “effect setting process” is executed in steps R5, R9, and R13, the process returns to step S3 of the main process (FIG. 3). If it is determined in step R10 that the “VOICE R2” button is not pressed (NO), the process proceeds to step R21 (corresponding to step P21), and subsequent steps R21 to R35 (FIGS. 14 and 15) [ In each of steps P21 to P35], exactly the same processing as steps P21 to P35 (FIG. 6) of “panel setting processing 1” is executed.
[0099]
[Effect setting process]
16 and 17 are flowcharts showing an effect setting process routine executed in steps R5, R9, and R13 (FIGS. 13 and 14) of "panel setting process 2" according to one embodiment of the present invention. This processing routine involves static setting of insertion effects for parts R1, R2, and L (including song recording). In the first step R51, it is determined whether or not effect setting information (effect setting data) for setting an effect is included in the timbre set in the parts R1, R2, L, etc. If included, go to the sequential processing flow of steps R52 to R54 to set the effect.
[0100]
First, in step R52, the setting state of the DSP of each part is checked to find a vacant effect imparting means (DSP). In the next step R53, the vacant DSP is replaced with the part (R1, R2, L). In step R54, an effect (insertion effect) is set using the assigned DSP.
[0101]
In the “panel setting process 1”, the system displays a DSP that can be assigned to the display DP and prompts the user to set an appropriate DSP [Step P53 (FIG. 7), FIG. 8 (2), ( 3B)], and the method of automatically determining and setting a free DSP on the system side as in step R53 is preferable in that the user is not aware of DSP1 to DSP3. If there is no vacant DSP, use the “review DSP settings for all parts according to priority order of priority processing table” supplementarily described in step Q56 of “DSP allocation processing” in FIG. It is possible to automatically determine and set an appropriate DSP on the system side.
[0102]
When it is determined in step R51 that the effect setting information is not included, and after the effect setting process in step R54, the process proceeds to step R55. In Step R55, it is determined whether or not the user has operated a “DSP control” switch (not shown) for setting the DSP. If the operation of the “DSP control” switch is not detected, the process proceeds to step R56. However, if the operation of the “DSP control” switch is detected, the process proceeds to step R56 after the processes of steps R57 to R62 (FIG. 17). move on. In step R56, it is determined whether or not the “NEXT” button has been pressed. While the “NEXT” button is not operated, the process returns to step R55 to wait for the “DSP control” switch operation or the effect based on the “DSP control” switch operation. Continue the setting process.
[0103]
When the operation of the “DSP control” switch is detected and the process proceeds to step R57, whether or not the DSPs (DSP1 to DSP3) are currently turned on (allocated) in the part (R1, R2, L). If it is determined and turned on, in step R62, the DSP that has been turned on is turned off to cancel the assignment, and then the process goes to step R56, where the “NEXT” button is pressed or “DSP control” is again performed. Wait for the switch to be pressed.
[0104]
On the other hand, when the DSP is not turned on for the part (R1, R2, L), the process proceeds from step R57 to step R58 to find a free DSP. In the next step R59, the free DSP is replaced with the part. Assign to. Subsequently, in step R60, the effect type (insertion effect type) is displayed on the display DP of the display device 9, the user is prompted to select an effect, and the user selects an effect from the displayed ones. In step R61, the DSP assigned to the part is set so that the effect selected by the user is added to the part, and the process proceeds to step R56.
[0105]
Then, when the “NEXT” button is operated, an affirmative determination (YES) in step R56 causes the effect setting process flow to be exited, and the process proceeds to the next process (step S3 (FIG. 3) of the main process).
[0106]
[Various Embodiments]
As described above, the insertion effect setting function according to the present invention has been described according to the embodiment. However, the embodiment is not limited to the illustrated example. For example, with regard to the allocation priority order of DSP1 to DSP3, in the embodiment, when the effect giving means overlaps in a plurality of performance parts, the allocation of the effect giving means is changed according to the priority order. The priority order for assigning effect assigning means is determined for each part. When a performance part is designated, the effect assigning means is assigned to the performance part based on this priority order regardless of whether the effect assigning means is used or not used. Can be configured to be assigned to.
[0107]
With such a configuration, it is always possible for the user to set the effect providing means, so that the user does not need to be aware of the availability of the effect providing means. In addition, since the priority of assigning the effect applying means is determined regardless of the non-use of the effect applying means, it may not be possible to assign the effect applying means to a performance part with a low priority. It may be taken into account or a separate method such as searching for a vacant effect imparting means when allocation fails.

【The invention's effect】
As described above, according to the present invention (all claims), musical tone signals belonging to a plurality (n) of performance parts such as keyboard parts (R1, R2, L) and music data tracks (1 to 16) are processed. A plurality of (N) effect applying means (DSP: DSP1 to DSP3) for providing individual effects (insertion effects) for each musical tone signal of each performance part. The number (N) is smaller than the number of performance parts (n) (N <n). In a musical sound performance apparatus in which one effect applying means can be assigned to one performance part, the performance parts to which individual effects are applied When assigning to effect applying means, priority is assigned when there is no space in effect applying means, so effect assigning means are effectively assigned and effect resources are played during performance It is possible to effective use.
[0109]
More specifically, according to the main feature of the present invention (Claim 1), when assigning the effect imparting means to the performance part, when the designation or assignment of the same effect imparting means overlaps among a plurality of performance parts. If other effect imparting means that have not yet been specified or assigned have been searched, and no other effect assigning means has been searched, the effect assignment to all performance parts is performed based on a predetermined priority order for assigning effect assigning means. Since the designation or assignment of means is reviewed (review target 2), it is possible to automatically assign appropriate effect imparting means that is balanced among all performance parts.
[0110]
According to the present invention (Claim 2), when it is determined that the same effect applying means overlaps among a plurality of performance parts, the same overlap determined is determined based on a predetermined effect applying means allocation priority. Since the designation or assignment to the corresponding performance part is reviewed (review target 1), the predetermined priority is given when there is an overlap of the same effect providing means among a plurality of performance parts. The effect imparting means according to the rank can be automatically assigned.
[0111]
Furthermore, according to this invention (Claim 3), since the priority order for assigning effect assigning means can be arbitrarily set by the user, there is no space in the effect assigning means or the same effect among a plurality of performance parts. When there is an overlapping of the granting means, the effect giving means can be automatically assigned according to the priority order according to the user's preference.
