The present invention relates to a method and an apparatus for setting a split point of an electronic musical instrument.

[0002]

2. Description of the Related Art The key split originally appeared as one of the performance functions of a synthesizer, but is now mounted on an electronic piano and other various electronic musical instruments, and plays a tone according to a tone range. , A bass tone in the lower range, a piano tone in the higher range, etc., so that an ensemble performance alone can be performed. With the advent of the sampler, there are some sounds that have different timbres (waveforms) depending on the sound range, or can be divided into many sound ranges such as note numbers.

[0003]

However, although the functions and the like have been enhanced, the usage (operation) has been complicated, and the ensemble cannot be easily enjoyed. In other words, while the sound can be divided into many sound ranges, the operation procedure is complicated and difficult to use, and the number of controls (switches and the like) is too large. In order to avoid this, if the keys of the keyboard are also used as split point setting keys, press the left and right keys of the split point to set a split point between the keys, or press a single key In order to provide a split point at a predetermined end (the right end or the left end), a tone cannot be assigned to an end key in spite of a 88-key (key) full keyboard, and therefore the entire area is desired. Can't be assigned to the same tone,
It can be seen that there is a mistake (specification mistake) such as.

Accordingly, an object of the present invention is to provide a method and an apparatus for setting a split point of an electronic musical instrument that can set a split point of a key split simply and efficiently without adding a special mechanism or the like. I do.

This is for setting a split point for key splitting of an electronic musical instrument having the above-mentioned integer keys. An arbitrary i-th key (i is an integer satisfying 1 ≦ i ≦ n) in a predetermined direction is set as a first key. A first key input is performed as a key, and a second key input is performed using an arbitrary j-th key (j is an integer satisfying 1 ≦ i ≦ n) as a second key in a predetermined direction. In this case, the relationship between the i-th and the j-th is i <j, i = j, i

In this case, n function keys corresponding to the n keys for performance are provided, or function keys corresponding to the n keys for performance are displayed on a display or the like, and the i-th key is displayed. The first input can be performed using the key as a first key (by a corresponding function key), and the second input can be similarly performed using the j-th key as a second key (by a corresponding function key), In the second embodiment, a key for performance can also be used as described below. In any case, the first key input is made while thinking "this key is" (for example, pressing the first key), and the second key input is made while thinking "this side" (for example, right side: high frequency side). If you go (second
Key), the first key (this key) is included on the right (this side) and split from the left key. For this reason, since the first key input and the second key input are merely performed with a simple and intuitive operation, the split point of the key split can be set without adding a special mechanism or the like. . In addition, even when the key at the end is included in the sound range, the key at the end may be set as the first key and the other keys may be set as the second keys.

In this split point setting method and apparatus, a split point setting mode for setting a split point is set, and after the split point is set, the split point setting mode is released. Since it is possible to separate processes such as stopping other processes in the electronic musical instrument, it becomes easy to execute the split point setting process. The n keys are keys for performance, and when the split point setting mode is set, a first key is input using the first key, and a second key is input using the second key. Perform key input. That is, other special mechanisms are added without providing n function keys corresponding to the n keys for performance or displaying the function keys corresponding to the n keys for performance on a display or the like. Without performing, the n keys for performance can also be used as a key for setting a split point, and the split point can be set more easily and efficiently.

An error is notified by a display, a sound, or the like, indicating that the boundary is the boundary on the th side or the boundary on the (i-1) th side, but is not clear.
As a result, the user can be informed that the setting is impossible and can be grasped. In the case of the re-entry prompt, re-entry of at least one of the first key input and the second key input is prompted, so that the user can grasp the necessity of the re-input and stop or restart the operation. In this case, after prompting for re-input, for example, a process of returning to a state of waiting for input in a split (point) setting mode may be considered. In the case of the dual tone mode setting, a dual tone mode in which a plurality of tones are assigned to all of the n keys is set. For example, one of the high range and the low range is a piano tone, and the other is an organ tone. It can be set to be able to play simultaneously (dual) with the tone and the organ tone.

Further, in the split point setting method according to claim 1 or 2, the second key input step includes a duplicate key input prevention step of preventing an input of the same key as the first key as the second key input. Is preferred.

It is preferable to confirm when a key input is made.

In this split point setting method and apparatus, the input result of the first key input is determined when the second key input is performed while the operation of the first key input is continued. For this reason, even if the first key input operation is performed, it is not determined unless the second key input is performed in that state. Therefore, the first key input operation is interrupted halfway before the second key input, so that the split point can be set. Abort the configuration process,
Thereafter, it is possible to start over, and it is easy to respond flexibly to an operation error or the like of the first key input. Normally, in the state where the operation of the first key input is continued (for example, the state where the key is pressed), the same key input cannot be performed.
j can be prevented from being operated by the user. That is, it is possible to prevent the same key as the first key from being input as the second key input.

Next, the overall control flow of the electronic musical instrument 1 will be described with reference to FIG. When the process is started by turning on the power key 51s (power on) or the like, first, as shown in FIG.
In order to return to the state at the time of the 1s off operation (power off), initial settings such as restoring the saved control flags are performed (S1), and the reference (default) operation guide is displayed on the display screen 41. Is displayed as an initial screen (S2). In addition,
By performing a predetermined setting in advance, the display screen at the time of the previous power-off (when the operation is completed) can be displayed as an initial screen, or a predetermined screen such as an editor screen for editing a MIDI file can be displayed. Can be set (customized) as an initial screen.

After the initial screen display is completed (S2), a predetermined (predetermined) type of interrupt is permitted (S3). That is, an interrupt permission flag of a predetermined interrupt (initial permission interrupt) is set. Note that the type of interrupt allowed in the initial screen display state can also be customized.

The subsequent processing in FIG. 3, that is, the branch for judging whether or not there is an interrupt event (S4) and the various interrupt processing (S5) are conceptually shown. In the electronic musical instrument 1, when the initial screen display (S2) is completed, the initial permission interrupt is permitted (S3). Therefore, until some initial permission interrupt (the next time, the permission permitted at that time) occurs. (S4: No), other processing (may be omitted if not necessary) is performed (S6), and if any initial permission interrupt (permitted interrupt) occurs (S4: Yes), the processing shifts to each interrupt processing. When the interruption process is completed (S5), other processes are performed (S6), and the process returns to the interruption event standby state (S4: No).

In the various kinds of interrupt processing (S5), interrupts that are not permitted at that time are permitted or interrupts that are permitted at that time are prohibited (for example, an interrupt permission flag is reset). As a whole, interrupt processing necessary for various kinds of processing is connected one after another. Also, the interrupt processing for entering the processing for selecting the type of the initial permission interrupt (customization processing)
Since the initial permission interruption is automatically permitted, even if the user fails to customize (erroneously) and cannot perform the desired processing (interruption processing), the customization can be redone (or the power supply is turned on again after the redo). Can be replaced).

In the following, for simplicity of explanation, for example, all operations of each key 31 of the keyboard 3, all operations of the panel switch 51 of the panel 5, the pedals 6 of the pedal group 6
All of the interrupt processing generated by the user's operation (interrupt event) on the operation unit 20, such as insertion of the FD into the ESI (here, the FDD) 7 and the like, are all permitted from the beginning (initial permission). (It is interrupted).

Next, a method of setting a split point in the electronic musical instrument 1 will be described. First, this setting method is performed in a predetermined direction (here, left and right → rightward).
And a split point for a key split of an electronic musical instrument having first to n-th (n is an integer of 3 or more: 88 keys (88 keys in the case of a full keyboard)) keys. Key input (first key input) using an arbitrary i-th key (i is an integer satisfying 1 ≦ i ≦ n) in a predetermined direction, and after the first key input, arbitrary j in a predetermined direction. A key input (second key input) is performed with the (th) key (j is an integer satisfying 1 ≦ i ≦ n) as a second key.

For example, as shown in FIG.
Consider (k + m + 1) keys 31 from the (k) th to (i + m) th (k and m are arbitrary natural numbers).
First, as shown in FIG. 3B, an arbitrary i-th key (i is an integer satisfying 1 ≦ i ≦ n) is assigned to the first key (rightward (lower frequency side → higher frequency side: predetermined direction)) as shown in FIG. ), And after the first key input, as an arbitrary j-th item in the right direction (low-frequency side → high-frequency side: predetermined direction), here j = i + 1, j
The (= i + 1) th key is input as a second key ().

In this case, there are only three possible relationships between the i-th and the j-th, i <j, i = j, i> j. Then, in this state, if the relationship of i <j holds, a split point is set at the (i-1) -th boundary of the i-th first key, and the relationship between the i-th and j-th keys is i If the relationship> j is established, a split point is set at the (i + 1) -th boundary of the i-th first key.

In the state shown in FIG. 4B, since the relationship of i <j is established, the split point SP is set at the (i-1) -th boundary of the i-th first key (). That is, the second key () side including the i-th first key () (in this case, the high frequency side ([U] side) and the opposite side (in this case, the low frequency side ([L] side)) Is set to split point SP. In this case, the user feels that
Press the first key while thinking "this key is", and press the second key while thinking "this side" (for example, the right side here: high frequency side).
If a key is pressed, the first key (this key) is included on the right side (this side), and is divided from the left key. For this reason, a simple operation can be performed intuitively, and the first key and the second key can be used.
Since only the key is used, the split point SP of the key split can be set without adding a special mechanism or the like.

Similarly, as shown in FIG. 4C, an arbitrary i-th first key () is input, and then an arbitrary j = i + m-th second key () is input. Also in this case, since the relationship of i <j (= i + m) is established, the split point SP is set at the (i−1) -th boundary of the i-th first key (). That is, as shown in the figure, a split point SP for dividing the second key () side ([U] side) including the i-th first key () and the opposite side ([L] side) is set. I do. Also in this case, since only the first key and the second key are used, the split point SP of the key split can be set efficiently with a simple operation without adding a special mechanism or the like.

Next, as shown in FIG.
After the input of the first key (), an arbitrary j = i−1th (adjacent) second key () is input. In this case, since the relationship of i> j (= i−1) is established, the split point SP is set at the (i + 1) -th boundary of the i-th first key (). That is, as shown in FIG.
A split point SP that divides the second key () side ([L] side) including the i-th first key () and the opposite side ([U] side) is set. Also in this case, since only the first key and the second key are used, the split point SP of the key split can be set simply and efficiently without adding a special mechanism or the like.

Further, as shown in FIG.
After the setting of the first key (), an arbitrary j = ik-th second key () is set. In this case, i> j (=
Since the relationship of (i-1) is established, the split point SP is set at the (i + k) -th boundary of the i-th first key (). That is, as shown in the figure, the second key () side including the i-th first key () ([L] side)
And a split point SP for dividing the opposite side ([U] side). Also in this case, since only the first key and the second key are used, the split point SP of the key split can be set simply and efficiently without adding a special mechanism or the like.

Here, as shown in FIG. 5A, in the case where the first to n-th keys are provided and all the keys up to the end are to be included in the [L] -side sound range, FIG. As shown in b), after inputting the nth key as the first key (), another arbitrary key may be used as the second key () (same as FIG. 4D or 4E). Conversely, when it is desired to include the first key in the [U] side range, FIG.
As shown in FIG. 4, after the first key is input as the first key (), another arbitrary key may be used as the second key () (the same as FIG. 4B or 4C). That is, even when the key at the end is included in the sound range, the key at the end may be set to the first key () and the other keys may be set to the second key ().

Next, as described above, in the electronic musical instrument 1, as a whole, processes in which interrupt processes required for various processes are connected one after another are performed. The input interruption relationship by each key (board key) 31 will be described together. If there is any board key input, the electronic musical instrument 1 generates a board key interrupt and activates a board key event process (S10). As shown in FIG. 6, first, it is determined whether or not a split setting mode is set. (S
11), if not in the split setting mode (S11: N
o), other processing is executed (S12), and the processing (S1) is executed.
0) is ended (S20).

Here, the split setting mode (split point setting mode) is a mode for setting a key split in the electronic musical instrument 1, more precisely, a mode for setting a split point of the key split. Setting switch 51g (FIG. 2)
Press (see) to set. If the split setting mode is not set (S1
1: No), and other processing (S12), for example, when each key 31 of the keyboard 3 is pressed for performance, etc., so that sound generation processing corresponding to each key 31 is performed (S12). The process (S10) ends (S20).

In this case, since the setting of the split (point) setting mode is performed before the first key input, the first (first) key setting mode is performed.
Split point setting operations such as key input and second key input can be reliably performed. Further, a split (point) setting mode for setting a split point is set, and after setting the split point, the split (point) setting mode is released (see S17).
Therefore, during the period from mode setting to release, processing such as stopping other processing in the electronic musical instrument 1 can be separated (interruption prohibition or the like), and the split point setting processing can be easily performed.

Note that the mode release described above is not automatically performed,
The split point setting switch 51g may be manually operated by pressing the switch 51g again, or may be used together. Further, a switch that is held in a pressed state and returned by pressing the switch again, or a push / pull type switch can be used.

Further, for example, a push button type which returns when released is performed, and the operation is performed up to the first key input or the second key input during the pressing (while the preparation operation is being performed).
The input result during that time is stored, and after the input, the mode is set (the mode is determined), and the split point setting process described below (S13 to S1 in FIG. 6)
8) may be processed. In this case, during the period in which the split point setting switch 51g is pressed (preparation operation period: preparation period) and after the mode is set (confirmed) until the mode is released, other processing can be separated (interruption prohibition, etc.). While the point setting process becomes easy to execute, the split point setting process can be stopped by releasing the split point setting switch 51g before the mode is set (determined), and the split point setting process can be started again. It becomes easy to respond flexibly to a key press error or the like.

When the split point setting mode is set, an image of the keyboard 3 is output (displayed) to the display 4 and thereafter, the position of the set split point is displayed on the image. You can also devise it.

Here, assuming that the mode is the split (point) setting mode (S11: Yes), next, as shown in FIG. 6, it is determined whether or not the key is the first key (S11).
13). As described above with reference to FIG. 4 and the like, since the first input is the first key, it is first determined that the key is the first key (S1).
3: Yes), the first key input is confirmed (S14), and when the next key input is made, the key is determined as the second key (S13: N).
o) Next, whether or not the “second key <first key” (the second key is on the left side), that is, i> j (FIG.
(D) or (e) is determined (S1).
5).

If this is the case (S15: Yes), a split point is set on the "+" side of the first key (high frequency side, right side: that is, the side opposite to the second key) (S15).
16), the split (point) setting mode is released (S19), and the process is terminated (S20). If it is not applicable (S15: No), then it is determined whether or not “first key <second key” (the second key is on the right side), ie, i <j (FIG. 4 (b ) Or (c)) is determined (S17).

If this is the case (S17: Yes), a split point is set on the "-" side of the first key (lower frequency side, left side: ie, opposite to the second key) (S17).
18), the split (point) setting mode is released (S19), and the process is terminated (S20). If not applicable (S17: No), then a duplicate key process is performed (S30), and the process ends (S20).

This duplicate key processing (S30) is, so to speak, "how to process when the same key is designated as the first key and the second key". Various methods can be considered and adopted. First, as a first method, simply
"The first key and the second key are the same key", that is, the split point is set to the "+ side" of the first key.
(I + 1 side: right side: high-frequency side) or "-side"
(I-1 side: left side: low band side), but it is displayed on the display 4 that the image is not clear, or an error is notified by a sound such as a beep sound. As a result, the user can be informed that the setting is impossible and can be grasped.

Alternatively, as a second method, when the relationship of i = j is established independently or independently of the error notification, the user is prompted to re-input at least one of the first key input and the second key input. This allows the user to understand the necessity of re-input, and to stop or start again. In this case, after prompting for re-input, in the example of FIG. 6, for example, the input of the first key and the second key is cleared,
That is, it is possible to return to the split (point) setting mode and wait for input.

Alternatively, as a third method, i = j
The first key input and the second key input that satisfy the relationship are used. For example, it is used as a mode setting condition for another mode. In this case, as another mode, for example, one of the high range and the low range is set to a piano tone, the other is set to an organ tone, and the entire range is set to a piano tone and an organ tone.
A dual tone mode in which two tones are simultaneously generated when each key of the entire area is pressed may be set, or a mode in which, for example, velocity split or key scaling (level scaling, rate scaling, etc.) is set, or the like. You can also set it.

In addition to the above, duplicate key processing (S3
0), i.e., i = j can be prevented at the key input stage. For example, the second key input (i = j) of the same key number as the key number of the first key input (corresponding to i described above) is determined and ignored (the second key input wait is waited again without input).
What is necessary is just to insert processing, such as. Further, in this case, it may be arranged such that the same key cannot be duplicated in the key input operation. For example, if the first key input is determined when the second key input is performed while the key is pressed, the key press for the first key input cannot be interrupted until the second key input is performed. , The second key input by the same key, that is, i = j,
It can be prevented by the operation of the user. In this case, even if the first key is pressed, it is not determined unless the second key is input in that state. Therefore, by releasing the first key halfway before the second key input, the split point setting process is stopped. Or the user can start over again afterwards, which makes it easier to respond flexibly to a mistake in pressing the first key (misoperation).

In the above-described embodiment, n (here, n = 88) keys of the keyboard for performance are used as they are for setting the split point. The function keys corresponding to the n keys for performance are displayed on a display or the like, and the i-th key is set as the first key, and the n-th function key is set as the first key. One input can be performed, and similarly, the second input can be performed using the j-th key as the second key and the corresponding function key. The second key input (that is, the designation of the affiliation of the first key) can use a method other than the key designation (a method by detecting another operation, etc.). In this case, for example, whether the right end (high frequency side) or the left end (low frequency side) of the first key is pressed is detected by a pressure sensor or the like, and a split point is set at the right or left end of the first key. Or a method of providing the first key on the right or left side.

In the above-described embodiment, an example of an electronic musical instrument of the electronic piano type has been described. However, the split point setting method and apparatus of the electronic musical instrument of the present invention may be any electronic musical instrument having a key split function. It can be applied to other types (for example, an electronic organ type) and a synthesizer. In addition, when used for these, modifications can be made as appropriate without departing from the gist of the present invention.
