Description

  The present invention relates to a tone color designation device, an electronic musical instrument, and a tone color designation processing program.

Conventionally, functions such as split and dual have been known for producing a plurality of different tone musical tones with a single instrument. In the split, the keyboard of the electronic musical instrument is divided into a plurality of key ranges, and a different tone color is assigned to each key range. Dual means that multiple types of musical tones are played simultaneously by operating one key on the keyboard.
In this conventional split function, first, a split mode is set by a split switch or the like, and the keyboard is divided into a plurality of key ranges such as an upper key range and a lower key range, and different tone colors are designated and assigned for each key range. Furthermore, the division position of the key range can also be changed by a user operation. For example, by pressing any key on the keyboard, the position where the key is located is designated as the division position.
If you forget to set at least one of the timbres in each key range, the other timbre that you did not forget is automatically set to the key range you forgot to set, or you There is also a proposal for setting a desired tone color in the entire key range when the setting is forgotten (for example, Patent Document 1).

JP-A-5-333860

However, in the configuration as disclosed in Patent Document 1, when a setting is forgotten, it is possible to prevent a situation where a key is not sounded even if a key is pressed, but a so-called normal function in which one tone is assigned to the entire key range is automatically used. The user who recognizes that the split function has been set is very uncomfortable and may be erroneously recognized as a failure.
In addition, in the split function, it is necessary to set the tone assigned to each key range, but in addition to that, it is necessary to set the division position to divide the keyboard for each key range. You may forget this setting.
Such a forgotten setting of the division position cannot be dealt with by the configuration of Patent Document 1.

  An object of the present invention is automatically set to a split function having a timbre or division position that seems to be most appropriate even if the setting of the timbre of each key range necessary for the split function or the setting of the division position is forgotten. There is in doing so.

To achieve the above object, the present invention provides a first register capable of storing timbre data corresponding to a timbre of a musical tone generated by pressing a key and any key included in the upper key range of the keyboard.

Further, the search means, when said plurality of sets of history data from the history storing means is searched, among the plurality of sets of history data, corresponding to the stored value of the count is the largest set of history It is desirable to select data.

In addition, when the set of history data is not searched from the history storage means, the search means sets a set of data composed of data of a predetermined tone color and division position as a selected set of history data. Is desirable.

In addition, when the split function designation unit changes the designation of the split function from non-setting to setting , if the data is not stored in all of the first and second registers and the division position storage unit, the history It is desirable to further include third storage control means for storing a set of data corresponding to the maximum number of times stored in the storage means in each of the first and second registers and the divided position storage means.

Further, the present invention includes a tone color designation unit, and the key depression detecting means for detecting the key depression before Symbol keyboard, when the split function is set, the detected key depression by the key depression detecting means A discriminating means for discriminating whether the key is included in the upper key range or the lower key range, and if the discriminating unit determines that the key is included in the upper key range, it corresponds to the pressed key Instructs the sound source to generate a musical tone based on the pitch and the timbre indicated by the timbre data stored in the first register, and if it is determined that the musical tone is included in the lower key range, the depressed key And a first sound generation instruction means for instructing the sound source to generate a musical tone based on a tone corresponding to the tone and tone color indicated by tone color data stored in the second register, and when the split function is not set , A sound corresponding to the pressed key And characterized in that it has a second sound instruction means for instructing the sound source generating tone based on the tone color selected by said tone color selection means.

Further, the present invention relates to a keyboard, a first register capable of storing timbre data corresponding to a timbre of a musical tone produced by pressing any key included in the upper key range of the keyboard, A second register capable of storing timbre data corresponding to the timbre of a musical tone generated by pressing one of the keys included in the lower key range, and the division position of the upper key range and the lower key range can be stored Split position storage means, history storage means capable of storing the contents stored in the first and second registers and the split position storage means as a set of history data, and the keyboard as upper key range and lower key the computer to be applied to the tone color setting apparatus having a split function designating means for designating any of the settings and non-setting of the split function to split into a band, and is set in the split function specified by the split function designation means That in the state, and when the selection of the tone color is made, the tone color setting step of storing the sound data to at least one of said first and second register corresponding to the tone to which the selected, by the split function designation means A split position specifying step of storing the specified split position in the split position storage means when the split function setting is specified and the split position is specified; and the split function setting means When data is not stored in any of the first and second registers and the division position storage means when the split function is changed from non-setting to setting, the data is stored . first, a search step of searching a set of historical data from the history storage unit based on the contents of the second register and the division position storage means The corresponding data of the retrieved set of historical data, the first that is not the storage, a storage control step of storing in the second register and the division position storage means, the split function by the split function designation means A history update step of updating the contents of the history storage means based on the contents stored in the division position storage means and the first and second registers when the designation is changed from setting to non-setting; It is characterized by making it.

  In the split function, the tone color and division position assigned to each key range are often fixed to some extent with a few exceptions. That is, there is a very high possibility that the setting is the same as the previously set tone color and division position. The present invention pays attention to this point, and automatically sets the most frequently set timbres or division positions in the past with respect to the timbre or division position of the key range where the setting has been forgotten. As a result, even if you forget to set the timbre or split position required for the split function, the most appropriate timbre or split position is automatically set. In addition to being able to prevent this situation, the normal function does not cause the user to feel uncomfortable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of an electronic musical instrument to which the timbre setting device of the present invention is applied.
In the figure, a CPU 1 controls the processing operation of the entire electronic musical instrument based on a program stored in a program ROM 2. The program ROM 2 also stores a plurality of types of tone color data. The RAM 3 temporarily stores data used for the processing of the CPU 1, and the number of times for each tone color set in each of the register group to be described later or the key range in the past, and further the number of times for each division position. A memory area is also provided.

The SW unit 4 includes a tone color switch group for designating the tone color of a musical tone to be generated, a split switch, a key range designation switch, and a mode switch.
The tone color switch group has an independent switch corresponding to each tone color data stored in the program ROM 2 described above. The key range designation switch is a switch for designating a key range to which a timbre should be assigned. In the present embodiment, the key range designation switch is configured to designate either the upper key range or the lower key range. The mode switch is a switch for switching between a mode for setting a timbre or division position necessary for the split function and a mode for performing normal performance. The split switch is a switch for switching setting / non-setting of the split function.

The keyboard 5 is used to specify the tone generation / mute and the pitch of the musical tone. The tone generator unit 6 generates a musical tone corresponding to the pitch and tone color sent from the CPU 1 and supplies it to the tone generation unit 7 to generate the tone. It is something to be made.
On the other hand, the display unit 8 displays timbre names assigned to the keyboard and other parameters necessary for performance.

FIG. 2 is a diagram showing the contents stored in the RAM 3 of FIG. In the figure, SPLIT [] is an area for storing the setting state of the split function and the number of times of setting, and this area is divided into areas SPLIT [0] to [N] for each setting state of the split function. Yes.
SPLIT [0] is assigned to SPNOTE [0] in which the key number corresponding to the division position is stored, UPNTONE [0] in which the tone number assigned to the upper key range is stored, and the lower key range. UPNTONE [0] for storing the timbre tone number is stored. In this embodiment, these three types of data are used as a set of data representing the setting state of the split function. SPLIT [0] further has an area of NUM [0], in which a set number of sets of data representing the setting state of the split function is stored. The same applies to the other TONENUM [1] to [N].

  TONE stores the timbre number corresponding to the timbre selected by the timbre switch group, and UPPER and LOWER store the timbre number corresponding to the timbre assigned to each of the upper key range and the lower key range.

  The UPF is a flag that changes from “0” to “1” when a timbre is assigned to the upper key range, and the SPF is a flag that changes from “0” to “1” when the split function is set. In addition, MF is a flag which is “1” in a mode for setting a tone color or a division position necessary for the split function and “0” in a mode for performing a normal performance.

  Further, NOTE stores a key number representing a pressed key, and SPLIT stores a key number as a set division position. Each of SPNOTE, UPNOTE, and LOWNOTE temporarily stores a key number representing a division position and a timbre number representing a timbre stored in the upper and lower key ranges.

  Further, N stores the number of data representing the setting state of the split function stored in the SPLIT [] area, and n stores a pointer value for designating SPLIT []. .

FIG. 3 is a main flowchart showing the operation of the CPU 1 of FIG.
First, when the power is turned on, the CPU 1 is set to an initial state, and an initialization process is performed to set the contents of the work RAM 3 to default values (step S1). Subsequently, in the SW process, a process based on the operation of the switch operated in the SW unit 4 is performed (step S2). In the keyboard process, a process based on key depression / release of the keyboard 5 is performed (step S3), and then other processes necessary for the electronic musical instrument are performed (step S4), and the process returns to step 2 again. This series of processing is repeated until the power is turned off.

  FIG. 4 is a flowchart showing details of the initialization process of FIG. First, all the flags in the RAM 3 are set to “0” (step S10), and then the contents of the RAM 3 excluding SPLIT [] and N are cleared (step S11). Next, a timbre number representing a predetermined timbre is stored in TONE, and this process is terminated (step S12).

  Since SPLIT [] stores the setting state of the split function stored in the past, the contents are not cleared when the power is turned on / off. Since N is also the number of data stored in SPLIT [], this is not cleared. N may count the number of data in SPLIT [] each time the power is turned on and store the number.

  FIG. 5 is a flowchart showing details of the switch processing of FIG. Here, processing is performed in the order of mode switch processing (step S20), key range designation switch processing (step S21), tone color switch processing (step S22), split switch processing (step S23), and finally other switch processing. (Step S24) is executed and this process is terminated.

  FIG. 6 is a flowchart showing details of the mode switch process of FIG. First, it is determined whether or not the mode switch is turned on (step S30). If it is determined that it has not been operated, the process is terminated. If it is determined that it has been turned on, the process proceeds to step S31, and the flag stored in the MF is inverted. Subsequently, it is determined whether or not the inverted flag is “1” (step S32). If it is not “1”, that is, if it is the normal performance mode, this processing is terminated, but “1”, that is, the setting is made. If it is the mode, the contents of UPPER, LOWER, and SPLIT are cleared and this process is terminated (step S33).

  In this way, each time the mode switch is turned on, the mode is reversed and shifted to either the setting mode or the normal performance mode, and when changing to the setting mode, the timbre and division position previously assigned to the upper and lower key ranges are cleared. Is done.

FIG. 7 is a flowchart showing details of the key range designation switch process of FIG.
First, the key range designation switch is operated to determine whether or not the upper key range has been designated (step S40). If it is determined that the upper key range has been designated, the flag stored in the UPF is set to “1” and the process is terminated (step S41).
If it is determined in step S40 that the upper key range has not been specified, the process proceeds to step S42 to determine whether or not the lower key range has been specified. If it is determined that the lower key area has not been specified, the process is terminated. If it is determined that the lower key area has been specified, the flag stored in the UPF is set to “0” and the process ends. (Step S43).

  In this way, by operating the key range designation switch, the flag stored in the UPF becomes “1” or “0”. When “1”, the upper key range is designated, and when it is “0”, the lower key range is designated. Is specified.

FIG. 8 is a flowchart showing details of the timbre switch process of FIG.
First, it is determined whether or not any of the timbre switch groups has been turned on (step S50). If it is determined that the ON operation has not been performed, the process is terminated as it is.
If it is determined that the ON operation has been performed, it is determined whether or not the flag stored in the SPF is “1”, that is, whether or not the split function is set (step S51). Here, when it is determined that the flag is “1”, that is, the split function is set, this time, whether or not the flag stored in the MF is “1”, that is, the tone required for the split function. And it is determined whether or not it is a setting mode in which the division position can be set (step S52).

  If the flags stored in the SPF and MF are both “1”, that is, if the split function is set and the setting mode is set, the process proceeds to step S53, and the flag stored in the UPF is “1”. It is determined whether or not.

  When the flag stored in the UPF is “1”, that is, when the upper key range is designated, the timbre number representing the timbre corresponding to the determined timbre switch turned on in step S50 is UPPER. (Step S54). Conversely, when the flag stored in the UPF is “0”, that is, when the lower key range is designated, the timbre number representing the timbre corresponding to the determined timbre switch turned on in step S50 is set. The data is stored in the LOWER and the process is terminated (step S55).

  On the other hand, if at least one of the flags stored in the SPF and MF is determined to be “0” in steps S51 and S52, that is, if the split function is not set and the split function is set, If it is in the performance mode, the process proceeds to step S56, where the timbre number representing the timbre corresponding to the determined timbre switch turned on in step S50 is stored in TONE, and this process is terminated.

  Thus, when the timbre switch is turned on while the split function is set and in the setting mode, the timbre corresponding to the timbre switch is assigned to the key range designated by the key range designation switch. . If the timbre switch is turned on when not in this state, the timbre number representing the designated timbre is temporarily stored in TONE.

9 to 11 are flowcharts showing details of the split switch process of FIG.
First, it is determined whether or not the split switch is turned on (step S60). If it is determined that the on-operation is not performed, the process is terminated. If it is determined that the on-operation is performed, the flag stored in the SPF is inverted (step S61). Subsequently, it is determined whether or not the inverted SPF flag is “0” (step S62).

  If it is determined that the SPF flag is “0”, this means that the split function is not set, and the process proceeds to step S63, where the contents of SPLIT [0] to [N] in the RAM 3 are displayed. Search for. Among SPLIT [0] to [N], there are SPLTs (division positions), UPPER (upper key range timbre), and LOWER (lower key range timbre) that indicate the setting state of the previous split function. Whether there is data set in the same state in the past (step S64).

When it is determined that the same thing exists, the point value corresponding to the address on the RAM 3 of the SPLIT [] retrieved as the same is stored in n (step S65), and this n is designated as an argument. The number of times stored in [n] is incremented and this process is terminated (step S66).
In this way, if the split function state set immediately before the split function is not set has been set in the same way in the past, the number of times stored corresponding to this set state is incremented. To do.

  If it is determined in step S64 that the same data does not exist, this set state must be stored in SPLIT [] as new data. For this reason, first, a necessary area is secured in the RAM 3 (step S67). Subsequently, in order to increase the number of data secured in SPLIT [], the number of data stored in N is incremented (step S68). Then, SPLIT (key number indicating the division position) and UPPER (tone color number assigned to the upper key range) are respectively assigned to the newly reserved areas SPLIT [N], UPTONE [N] and LOWTONE [N]. LOWER (timbre number assigned to the upper key range) is stored (step S69). Finally, “1” is stored in the area NUM [N] in this SPLIT [N], and this process is terminated (step S70).

  As described above, when it is determined that the state of the split function set immediately before the split function is not set has been set in the past, the new split function setting state is indicated in SPLIT []. Store as data. In this way, the history representing the past split function setting state is updated.

  On the other hand, if it is determined in step S62 that the SPF flag is “1”, this means that the split function has changed from the non-set state to the set state. In this case, the process proceeds to step S71 in FIG. 10, and SPLIT (key number representing the division position), UPPER (tone color number assigned to the upper key range) LOWER (tone color number assigned to the upper key range) Whether or not is stored is determined.

If it is determined that the setting has not been forgotten and all of SPLIT, UPPER, and LOWER are stored, this processing is terminated as it is.
If at least part of SPLIT, UPPER, and LOWER is forgotten to be set, the same data as SPLIT, UPPER, and LOWER that has not been forgotten to be set is retrieved from SPLIT [0] to [N] (step S72). ). That is, for example, when the setting of the division position is forgotten, a search is made from SPLIT [0] to [N] for the same UPPER and LOWER contents for which setting has not been forgotten.

  Then, the process proceeds to step S73, and if it is determined that one identical one is found by this search, a pointer value indicating the same SPLIT [] is stored in n (step S74). Subsequently, the contents of SPNOTE [n], UPNOTE [n], and LOWNOTE [n] designated with n as an argument are stored in SPNOTE, UPTONE, and LOWTONE (steps S75 to S77). In this way, among the split function setting states stored in the past, the ones closest to the split function setting state currently set only partially are SPNOTE (key number indicating the division position), UPTONE ( Temporarily stored in a timbre number representing a timbre assigned to the upper key range and LOWONE (a timbre number representing a timbre assigned to the upper key range).

  If it is determined in step S73 that a plurality of identical items are found, one item must be selected from now on. For this purpose, NUM [] included in each of the plurality of searched SPLIT [] is referred to. This NUM [] stores the number of times the split function state has been set in the past, and in this embodiment, SPLIT [] having the maximum value of NUM [] is selected. The pointer value indicating the selected SPLIT [] is stored in n (step S78), and the process proceeds to steps S75 to S77.

As described above, when there are a plurality of search results, SPLIT [] having the largest set number of times in the past is selected.
Of course, there may be a plurality of NUM [] having the maximum value. In such a case, it is conceivable to randomly select one from SPLIT [] having the maximum value of NUM [].

  Furthermore, if it is determined in step S73 that no identical one is found, a predetermined division position and tone color are assigned. For this reason, a predetermined key number is stored in SPNOTE, and different predetermined timbre numbers are stored in UPTONE and LOWTONE (steps S79 to S81).

  Thus, when the current setting state of the split function is not set in the past, it is temporarily stored in a predetermined setting state.

  On the other hand, if it is determined in step S71 that nothing is stored in SPLIT, UPPER, and LOWER, that is, if all settings are forgotten, refer to NUM [] included in each SPLIT [], SPLIT [] having the maximum value NUM [] is searched (step S82). The pointer value indicating the selected SPLIT [] is stored in n (step S83), and the process proceeds to steps S75 to S77.

  If all the settings are forgotten in this way, the setting state with the largest number of settings in the past is selected. Here, there may be a plurality of NUM [] having the maximum value. In such a case, it is conceivable to randomly select one from SPLIT [] having the maximum value of NUM [].

  As described above, after steps S75 to S77 or steps S79 to S81 store key numbers representing division positions and timbre numbers representing timbres to be assigned to the upper and lower key ranges in SPNOTE, UPTONE, and LOWTONE, FIG. The process proceeds to step S84.

  Then, it is determined whether or not nothing is stored in SPLIT. If it is determined that nothing is stored, that is, if the setting of the division position is forgotten, the key number corresponding to the division position stored in SPNOTE is stored in this SPLIT (step S85). On the other hand, if it is determined that it is stored, the process of step S85 is not performed.

  Subsequently, it is determined whether or not nothing is stored in UPPER (step S86). If it is determined that nothing is stored, that is, if forgetting to set a timbre in the upper key range, the timbre number stored in UPTONE is stored in this UPPER (step S87). On the other hand, if it is determined that it is stored, the process of step S87 is not performed.

  Thereafter, it is determined whether or not nothing is stored in LOWPER (step S88). If it is determined that nothing is stored, that is, if the user has forgotten to set a timbre in the lower key range, the timbre number stored in LOWTONE is stored in this LOWER and the process is terminated (step S89). ). On the other hand, if it is determined that it is stored, this process is terminated without performing the process of step S89.

  In this way, when the split function is set to the set state, only the divided position and the upper and lower key ranges that are forgotten to be set, the divided positions and the upper and lower key ranges that are stored in SPNOTE, UPTONE and LOWTONE are automatically set. Will be set automatically.

FIG. 12 is a flowchart showing details of the keyboard processing of FIG.
First, the keyboard 5 is scanned (step S90), and the key state is detected (step S91). If there is no change in the key state, the process of this flow is terminated.

  When the key state is on to off, that is, when a key release is detected, the key number that has been released is stored in the register NOTE (step S92). Then, the sound source unit 6 is instructed to mute the musical tone having the pitch corresponding to the key number stored in the register NOTE (step S93).

  When the key state is off to on, that is, when a key depression is detected, the key number depressed is stored in the register NOTE (step S94). Subsequently, it is determined whether or not the flag stored in the MF is “1”, that is, whether or not the setting mode is set (step S95). If the flag is determined to be “1”, it is subsequently determined whether or not the flag stored in the SPF is “1”, that is, whether or not the split function is set (step S96).

  Here, if both of the flags stored in the MF and SPF are “1”, that is, if the split function is set and the tone color and division position necessary for the split function are set, the step is performed. Proceeding to S97, the key number stored in NOTE is stored in SPLIT in which the key number corresponding to the division position is stored, and this process is terminated. As described above, when a key is pressed in a state where the split function is set and the setting mode is set, the key number of the pressed key is designated as a division position.

  On the other hand, if it is determined in step S95 that the flag stored in the MF is “0”, that is, not the setting mode but the normal performance mode, the process proceeds to step S98, and the flag stored in the SPF is “0”, that is, It is determined whether or not the split function is not set. If it is determined that the flag is “0”, that is, the split function is not set, the tone corresponding to the pitch corresponding to the key number stored in NOTE and the tone number corresponding to the tone number stored in TONE is stored. Sound generation is instructed to the sound source unit 6 and this process is terminated (step S99).

  Further, when the flag stored in the MF is determined to be “1” in step S95 and the flag stored in the SPF is not “1” in step S96, that is, in the setting mode and the split function is not set. Similarly, the process proceeds to step S99.

  In this way, in either the normal performance mode or the setting mode, if the split function is not set, the timbre represented by the timbre number stored in the TONE, that is, the timbre switch, when any key on the keyboard is depressed. The musical tone of the tone selected at is generated.

  If it is determined in step S98 that the flag stored in the SPF is not “0”, that is, the split function is set, the process proceeds to step S100, and the key number corresponding to the division position stored in SPLIT is set. , It is determined whether or not the key number of the pressed key stored in the NOTE.

  If it is determined that the SPLIT key number is equal to or greater than the NOTE key number, that is, if it is determined that the key is pressed in the lower key range, the pitch corresponding to the key number stored in the NOTE and the LOWER The tone generator 6 is instructed to generate the tone of the tone corresponding to the tone number stored in step S101, and the process is terminated (step S101).

Conversely, when it is determined that the SPLIT key number is less than the NOTE key number, that is, when it is determined that the key is pressed in the upper key range, the pitch corresponding to the key number stored in the NOTE and the LOWER The tone generator 6 is instructed to generate the tone of the tone corresponding to the tone number stored in step S102, and the process is terminated (step S102).
As described above, when the normal performance mode is set and the split function is set, the musical tone having the tone color assigned to the key range pressed is generated.

  As described above, in the present embodiment, the timbre or division position set in the same state in the past is automatically set for the timbre or division position of the key range where the setting is forgotten. As a result, even if you forget to set the timbre or split position required for the split function, the most appropriate timbre or split position is automatically set. In addition to being able to prevent this situation, the normal function does not cause the user to feel uncomfortable.

  In this embodiment, when the split function is set to the set state, if it is forgotten to set all the timbres to be assigned to the split position and each key range, the split position and the timbre of the split function that has been set most frequently in the past. However, a preset division position and tone color may be set regardless of the past setting state. Also, if you forget to set a part of the timbre assigned to the division position and each key range, the preset division position and timbre are set regardless of the past setting state. You may make it set to the division | segmentation position and tone color of a split function with most setting frequency | counts.

  Furthermore, in the present embodiment, when assigning the same tone color in the entire keyboard range of the keyboard 5, the tone number representing the tone color selected by the tone switch is stored in TONE, but the same as UPPER and LOWER.
