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.
Moreover, the timbre of each key range can also be freely set by the user's timbre designation operation (for example, Patent Document 1).
JP 2008-76708 A

However, although which tone color is assigned to which key range can be set by the user, the setting procedure is often fixed. For example, in the configuration of Patent Document 1, the first designated tone color is assigned to the upper key range, and subsequently the designated tone color is designated by the procedure of being assigned to the lower key range.
For this reason, once the user has specified the timbre of the upper key range, even if he / she wants to assign this timbre to the lower key range, it has been time-consuming.
An object of the present invention is to make it possible to change the timbre assigned to each key range from the middle of the designation procedure.

  In order to achieve the above object, the present invention provides a keyboard, timbre designating means for designating a timbre, division position designating means for designating a division position for dividing the keyboard into an upper key range and a lower key range, Corresponds to the first register that can store timbre data that specifies the timbre of a musical tone that is sounded in response to the key depression in the upper key range, and the key depression in the lower key range of the keyboard In response to the specification of the timbre by the timbre designating means, the timbre data can be stored in either the first register or the second register in response to the timbre data specifying the timbre of the musical tone to be generated. Is stored, the timbre data indicating the designated timbre is stored in the first register, and if timbre data is stored in one of the two registers, the other register is stored. The specified sound Storage control means for storing timbre data indicating the timbre data, and when the division position is designated by the division position designation means in a state where timbre data for designating a timbre is stored in the first register, Moving means for moving timbre data stored in one register to the second register.

  Further, it is preferable that the division position designation means designates a position of a key pressed by the keyboard as the division position.

  The present invention also relates to the tone color designation device, key depression detecting means for detecting a key depression of the key of the keyboard, and keys detected by the key depression detection means as the upper key range and the lower key range. A discriminating means for discriminating which key is included, and if the discriminating means discriminates that it is included in the upper key range, the pitch corresponding to the pressed key and the first register are stored. If the sound source is instructed to generate a musical tone based on the timbre indicated by the timbre data, and is determined to be included in the lower key range, the pitch corresponding to the depressed key and the second register Sound generation instruction means for instructing the sound source to generate a musical tone based on the timbre indicated by the timbre data stored in the timbre.

  Further, the present invention includes a keyboard, a timbre specifying means for specifying a timbre, a split position specifying means for specifying a split position for dividing the keyboard into an upper key range and a lower key range, and an upper key range of the keyboard. A first register that can store timbre data that specifies the tone color of a musical tone that is sounded in response to a key depression, and a sound that is produced in response to a key depression in a lower key range of the keyboard. A computer applied to a timbre designating device having a second register capable of storing timbre data designating a timbre of a musical tone, in response to designation of a timbre by the timbre designation means, the first and second When no timbre data is stored in any of the registers, the timbre data indicating the designated timbre is stored in the first register and the timbre data is stored in one of the two registers. The other A storage control step for storing the timbre data indicating the specified timbre in the register and a timbre data for specifying the timbre in the first register; A moving step of moving the timbre data stored in the first register to the second register when designated.

  The present invention presupposes that the timbre is specified in the order of the upper key range and then the lower key range, but after the timbre of the upper key range is specified, the division position of the key range is specified. If this is done, the timbre assigned to the upper key range can be assigned to the lower key range, and the timbre specified subsequently can be assigned to the upper key range. For this reason, even after the timbre is assigned to the upper key range, the timbre to be assigned to the upper key range can be designated again, and it is not necessary to perform the timbre assignment operation from the beginning as in the prior art.

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 work RAM 3 temporarily stores data used for the processing of the CPU 1, and a register group and a flag group, which will be described later, are also configured using a part of this area.
The SW unit 4 includes a switch group for designating the tone color of the musical sound to be generated. This timbre switch group has an independent switch corresponding to each timbre data stored in the program ROM 2 described above. Furthermore, a split switch for setting the split mode, a split setting switch for setting a tone color and a division position assigned to the upper and lower key ranges, and the like are also provided.
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 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, a default value is set to a register group configured in the work RAM 3, and an initialization process is performed to set a flag group to an initial state (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). Then, a process based on key depression / release of the keyboard 5 is performed in the keyboard process (step S3), and a process of displaying on the display unit 8 is performed in the display process (step S4). Thereafter, other processing necessary for the electronic musical instrument is performed (step S5), and the process returns to step 2 again. This series of processing is repeated until the power is turned off.

3 and 4 are flowcharts showing details of the SW processing of FIG. First, it is determined whether or not the split switch of the SW unit 4 is turned on (step S10).
If it is turned on, the flag SPF indicating whether or not it is in the split mode is inverted (step S11), and the processing of this flow is terminated. The flag SPF indicates a split mode when “1” and a non-split mode when “0”, and is set to “0” in the initialization process of step S1.
If it is determined that the split switch is not turned on, it is determined whether or not the mode switch is turned on (step S12). If it is determined that it is turned on, the process proceeds to step S13, and the flag MF indicating whether or not the split setting mode is used for setting the tone color to be assigned to the key range and the keyboard division position is set to "1". This flag MF indicates a split setting mode when “1”, and a non-split setting mode when “0”, and is set to “0” in the initialization process of step S1.

Subsequently, flags UPF and LWF indicating whether or not a tone color has been set in each of the upper key range and the lower key range are set to “0”. These flags are set to timbre by “1” and not set by “0”. Further, the flag DIVF indicating whether or not the division position of the keyboard 5 has been set is set to “0”. This flag is set to “1” for division position and “0” for non-setting.
When the process of step S13 ends, the process of this flow also ends.
On the other hand, if it is determined that the mode switch is not turned on, it is determined whether or not the timbre switch is turned on (step S14). If it is determined that it is not turned on, the process of this flow is terminated.
If it is determined that the flag is turned on, the process proceeds to step S15 to determine whether or not the flag MF is “0”. Here, when the flag MF is “0”, that is, when the mode is not the split setting mode, it is subsequently determined whether or not the flag SPF is “0”, that is, whether the mode is the split mode (step S16). Here, when the flag SPF is “0”, that is, when the mode is not the split mode, the timbre data indicating the timbre corresponding to the timbre switch that is turned on is stored in the register UPPER capable of storing the timbre data indicating the timbre assigned to the upper key range. Store (step S17). After the process of step S17 is completed, or when the flag SPF is “1” and the mode is the split mode, the process of this flow is terminated.

As a result of this processing, if the timbre switch is turned on when not in the split non-setting mode and further in the split mode, that is, when the same tone color tone is produced in the entire key range, the corresponding tone color data is stored in the register UPPER. Will be remembered only.
On the other hand, if it is determined in step S15 that the flag MF is “1” and the mode is the split setting mode, the process proceeds to step S18 in FIG. 4 and the flag UPF is “0”, that is, no tone is assigned to the upper key range. To determine. If it is determined that the timbre is not assigned, timbre data indicating the timbre designated by the timbre switch is stored in the register UPPER (step S19), and the flag UPF is set to “1”, that is, the timbre is assigned to the upper key range. (Step S20).

If it is determined in step S18 that a timbre has already been assigned to the upper key range and the flag UPF is “1”, the process proceeds to step S21, where the flag LWF is “0”, that is, no timbre has been assigned to the lower key range. To determine. If it is determined that the timbre is not assigned, the timbre data indicating the timbre specified by the timbre switch is stored in the register LOWER capable of storing the timbre data indicating the timbre assigned to the upper key range (step S22). The flag LWF is set to “1”, that is, the tone is assigned to the lower key range (step S23).
After the processing of Steps S23 and S20, or when the flag LWF is “1” in Step S21, that is, when the timbre has already been assigned to both the upper and lower key ranges, the process proceeds to Step S24 and the flags LPF, LWF and DIVF are set. It is determined whether or not both are “1”. The state in which all these flags are “1” means that the timbre is assigned to the upper and lower key ranges and the division position is set, so that the flag MF is set to “0” in the subsequent step S25, and the split is performed. The setting mode is a non-setting mode. After the end of this process, or when the above-mentioned flags are not all “1” in step S24 and the setting of the split function has not ended, the process of this flow is ended.

In this way, when the timbre switch is turned on in the split setting mode, a timbre is assigned to a key range that has not been assigned a timbre in either the upper key range or the lower key range, and the timbre is assigned to all key ranges. When the allocation and the division position setting are completed, the split setting mode is changed to the non-setting mode.
5 and 6 are flowcharts showing details of the keyboard processing of FIG.
First, the keyboard 5 is scanned (step S30), and the key state is detected (step S31). If there is no change in the state, the process of this flow is terminated. If any key is turned off from on, that is, released, the key number of the released key is stored in the register NOTE (step S32). Then, the sound source unit 6 is instructed to mute the musical sound produced at the pitch corresponding to the key number stored in the register NOTE (step S33).

If any key is turned on from off, that is, the key is depressed, the key number of the depressed key is stored in the register NOTE (step S34). Subsequently, it is determined whether or not the flag MF is “1”, that is, in the split setting mode (step S35). If the flag MF is determined to be “1” in the split setting mode, the process proceeds to step S36, and the key number stored in the register NOTE is stored in the register SPLIT that stores the key number indicating the division position.
Thereafter, it is determined whether or not the flag UPF is “1” and the LWF is “0”, that is, whether or not a tone color is assigned only to the upper key range (step S37). If the timbre is assigned only to the upper key range, the timbre data stored in the register UPPER is stored in the register LOWER (step S38), the flag UPF is "0", and the flag LWF is "1". "(Step S39). Then, the flag DIVF is set to “1” (step S40), and the processing of this flow is finished.

On the other hand, if it is determined in step S37 that the timbre is assigned only to the lower key range, the process of steps S38 and 39 is skipped and the process proceeds directly to step S40.
Thus, when a key is pressed in the split setting mode, the position on the keyboard 5 corresponding to the pressed key is set as the division position. At this time, if the timbre is assigned only to the upper key range, the timbre assigned to the upper key range is assigned to the lower key range and the timbre is not assigned to the upper key range. .
That is, the timbre once assigned to the upper key range is moved to the lower key range, and a new timbre can be assigned to the upper key range.
If it is determined in step S35 that the flag MF is “0” and the mode is not the split setting mode, the process proceeds to step S41 in FIG. 6 to determine whether the flag SPF is “1”, that is, whether the mode is the split mode. If the flag SPF is “1” and the mode is the split mode, the process proceeds to step S42, and whether the key number indicating the division position stored in the register SPLIT is greater than or equal to the key number stored in the register NOTE. Determine whether or not.

If it is determined that the key number is equal to or greater than this, it means that the lower key range side has been pressed, and is indicated by the pitch corresponding to the key number stored in the register NOTE and the timbre data stored in the register LOWER. The tone generator 6 is instructed to generate a musical tone of the timbre (step S43).
On the other hand, if it is determined that it is less than, it means that the upper key range side has been pressed, and the pitch corresponding to the key number stored in the register NOTE and the tone color indicated by the tone data stored in the register UPPER The tone generator 6 is instructed to generate a musical tone (step S44).
Also, if it is determined in step S41 that the flag SPF is “0”, that is, it is not in the split mode, the process proceeds to step S44 to instruct the tone generation of the timbre assigned to the upper key range in all key ranges.

After the processes of steps S43 and S44, the process of this flow is terminated.
FIG. 7 is a flowchart showing details of the display process of FIG.
First, it is determined whether or not the flag SPF is “1”, that is, the split mode is set (step S50). If the split mode is selected, the process proceeds to step S51, where the timbre name indicated by the timbre data stored in the register UPPER and the lower key range are assigned as the timbre assigned to the upper key range on the display unit 7. As the timbre, the timbre name indicated by the timbre data stored in the register LOWER is displayed.

If it is not the split mode, the process proceeds to step S52, and the timbre name indicated by the timbre data stored in the register UPPER is displayed as the timbre assigned to the entire key range.
After this process, the process of this flowchart is terminated.
As described above, according to the present embodiment, after the timbre of the upper key range is designated, if the division position of the key range is designated, the timbre assigned to the upper key range is assigned to the lower key range. Then, the timbre specified can be assigned to the upper key range. For this reason, even after the timbre is assigned to the upper key range, the timbre to be assigned to the upper key range can be designated again, and it is not necessary to perform the timbre assignment operation from the beginning as in the prior art.
