Description

  The present invention relates to an electronic keyboard instrument having a continuous mode.

  2. Description of the Related Art An electronic keyboard instrument having a continuous mode is conventionally known.

  As such an electronic keyboard instrument, when the continuous mode (key range division mode) is selected, the keyboard is divided into two key ranges at a predetermined key division position, and the sound ranges of the respective key ranges are made the same. There is one that allows two players to play a single electronic keyboard instrument (for example, see Patent Document 1).

As with the conventional electronic keyboard instrument, when the continuous mode is selected, the keyboard is divided into two key ranges at a predetermined key division position, but the high-pitched side of the divided key range is lowered by one octave, There is also an electronic keyboard instrument in which the side is raised by two octaves to cause a slight shift in the range of each key range (see, for example, Patent Document 2). However, even in the latter electronic keyboard instrument, the sound range of each key range can be set to be the same as in the former electronic keyboard instrument. Further, Patent Document 2 discloses a repetitive bullet including a split position which is a parameter for determining a keyboard split position, and an upper transpose and a lower transpose which are parameters for transposing each key on the high and low sides of the divided key range. It is described that the parameter may be RAM data, and it is suggested that the user can arbitrarily change the keyboard division position and the range of each divided keyboard range by arbitrarily rewriting the contents of the continuous parameter.

Therefore, depending on the practice song used for pistol practice, the range often used in the practice song may be higher or lower. Even in the latter electronic keyboard instrument, the user has to reset the range (octave) of each key range manually.

  Also, the player in the left key range and the player in the right key range may perform different parts of the practice song.

Specifically, it is necessary to set the left key range slightly lower than the right key range (or vice versa). Also in this case, even in the latter electronic keyboard instrument, the user has to reset the range (octave) of each key range by manual operation.

  Further, in the former electronic keyboard instrument, as described above, the keyboard division position is the center key.

  In the present embodiment, the display device 8 includes an LED provided for each key to display a performance guide, a key range division position, a pitch “C4” (center position), and the like. Each LED is, for example, a two-color LED that emits two colors of red and green. The performance (key press) position and key range division position at the time of the performance guide are displayed in red, and the center position is displayed in green. . The LED is not limited to two-color light emission, but three-color light emission of red (R), green (G), and blue (B), or a combination of R, G, and B for multicolor light emission. It may be. In that case, it is preferable that the performance position at the time of the performance guide, the key range division position, and the position of the central door are emitted in different colors.

  The storage device 9 is, for example, a storage medium such as a flexible disk (FD), a hard disk (HD), a CD-ROM, a DVD (digital multipurpose disk), a magneto-optical disk (MO), and a semiconductor memory, and its driving device. The storage medium may be detachable from the drive device, or the storage device 9 itself may be detachable from the electronic keyboard instrument.

  FIG. 2 is a diagram showing an example of the format of automatic performance data.

  As shown in the figure, the automatic performance data is composed of a plurality of tracks, and each track has a range information, a note event (note on / off event), and a timing (a timing at which a note event located immediately after it is reproduced). Data) indicating a set, and is composed of sequence data formed by arranging them in the order of reproduction. In the present embodiment, the automatic performance data is mainly used for keyboard performance practice, so it is sufficient that at least right hand part data and left hand part data are included. Therefore, the data of other parts, that is, the data after the track 3 are not essential in the present embodiment, and may or may not be included, and thus are indicated by a one-dot chain line. The range information is information indicating the range of the note event included in the track, that is, the range from the lowest pitch to the maximum pitch of all the note events included in the track.

  The format of the illustrated example is merely an example, and the automatic performance data does not include the range information or part information (for example, SMF (standard MIDI file) format automatic performance) is included in one track. In the case of data, note events (+ timing) with MIDI channels) are arranged in the order of reproduction. In the case of using the former automatic performance data, the CPU 5 may analyze the pitches of all note events included in each track so as to obtain the tone range for each track. When the latter automatic performance data is used, the CPU 5 generates automatic performance data for each part, analyzes the pitches of all note events included in the part for each part, and generates a range for each part. Should be requested. Needless to say, event data other than note events may be included in the automatic performance data.

  The automatic performance data may be stored in advance in the electronic keyboard instrument (ROM 6 or storage device 9) of the present embodiment, may be supplied from a removable storage medium, or may be the communication I / O It may be supplied from an external device (for example, a music content distribution server on the Internet) via F10.

  Further, the automatic performance data may correspond to one piece of music or may correspond to some phrases in the music. Or the thing corresponding to the phrase for practice which has nothing to do with music may be used.

  A control process executed by the electronic keyboard instrument configured as described above will be described first with reference to FIGS. 3 to 5 and then in detail with reference to FIG.

The electronic keyboard instrument of the present embodiment is provided with a normal mode and a continuous mode as operation modes, and the continuous mode is provided with a song mode and a non-song mode. Here, the song mode is a mode in which the automatic performance data selected by the user is reproduced for some purpose (for simple listening, for performance guides, for coincidence determination, for score display, etc.). When the continuous mode & (and) song mode is selected, the CPU 5 performs the following operation according to the selected mode among the first to third key range division / sound range setting modes, as follows: The entire keyboard range is divided into left and right key ranges at predetermined key range division positions, and predetermined sound ranges are set in the left and right key ranges, respectively.
(M1) First key range division / sound range setting mode: Dividing into left and right key ranges at a predetermined key range division position (in this embodiment, the center position of the keyboard), and automatic performance data currently selected Depending on whether the sound range corresponds to one of the low, middle, and high sound ranges, the corresponding sound range is set for each of the left and right key ranges (FIG. 3).
(M2) Second key range division / sound range setting mode: automatic performance data that is currently selected while being divided into left and right key ranges at a predetermined key range division position (in this embodiment, the center position of the keyboard) The left hand part's range is set to the left key range, and the right hand part's range is set to the right key range (Fig. 4).
(M3) Third key division / tone range setting mode: Determines the key division position so that the right key range includes all the ranges of the currently selected automatic performance data, and sets the automatic performance data to the right key range. And the range of the left key range is determined and set according to a predetermined rule (FIG. 5).

  Then, in order to inform the user of the set range of the key range division position and the left and right key ranges, the CPU 5 causes the LED provided in the vicinity of the key at the key range division position to emit red light, and to set the center region of each of the left and right key ranges. The LED provided in the vicinity of the key at the position is made to emit green light. 3 to 5, red light emission is represented by a black square “■” and green light emission is represented by a black circle “●”. This is because the drawing cannot be colored. Therefore, the shape of the LED provided for each key viewed from above is all circular, and there is no square shape.

  As described above, in the electronic keyboard instrument according to the present embodiment, it is possible to automatically and appropriately set the sound range and the keyboard division position of each key range in accordance with the situation where the rendition is performed.

  Next, this control process will be described in detail.

  FIG. 6 is a flowchart showing a procedure of control processing executed by the electronic keyboard instrument of the present embodiment, particularly the CPU 5.

This control process is mainly
(1) Performance processing in normal mode (step S2)
(2) Basic bullet state setting process (step S3)
(3) Performance processing in the basic repetitive state (step S5)
(4) Basic bullet state change processing (steps S6 to S10)
It is constituted by.

  In the electronic keyboard instrument of the present embodiment, the default operation mode is the normal mode. Therefore, the operation mode continues the normal mode unless the user actively changes the operation mode. At this time, the CPU 5 repeats the performance processing in the normal mode (1) (step S1 → S2 → return → S1). (1) In the performance processing in the normal mode, when the user presses the keyboard, the CPU 5 acquires the key pressing state from the detection circuit 3, and generates a note-on event corresponding to the acquired key pressing state. The sound source / effect circuit 11 is supplied. Here, the generated note-on event is a sound corresponding to a normal key pressing operation, that is, a tone having a pitch originally assigned to the key that has been pressed. The sound source / effect circuit 11 sets a musical tone parameter for generating a musical tone signal corresponding to the supplied note-on event in a corresponding register. The sound source / effect circuit 11 generates a musical sound signal based on the set musical sound parameter at a predetermined timing, and supplies it to the sound system 12. The sound system 12 generates and outputs sound corresponding to the supplied musical sound signal.

  When the user switches the operation mode from the normal mode to the continuous mode using, for example, an operation mode switch (not shown) included in the setting operator 2, the CPU 5 performs the process in the basic continuous state of (2). Proceed to the setting process (steps S1 → S3). In the (2) basic repetitive state setting process, first, the CPU 5 divides the left and right key ranges into substantially the same pitch range at a predetermined key range division position (in this embodiment, the center position of the keyboard). The same tone is assigned to the left and right key ranges, and the left and right pedals of the three pedals are set as damper pedals for the left and right key ranges, respectively. Such a setting state is hereinafter referred to as a “basic repetitive state”. The basic repetitive state is stored in a basic repetitive state storage area (not shown) secured at a predetermined position of the RAM 7 and also supplied to the sound source / effect circuit 11. The tone generator / effect circuit 11 is set to each setting information (key range division position, each tone range set to the left and right key ranges, tone assigned to the left and right key ranges, and left and right pedals included in the supplied basic repetitive state. Function) is set in the corresponding register.

  Next, the CPU 5 causes the LED provided in the vicinity of the key at the key range division position to emit red light, and causes the LED provided in the vicinity of the key at the center position of each of the left and right key ranges to emit green light.

  For example, each pitch originally assigned to each key in the left range is shifted upward (in the increasing direction) by two octaves (Oct), and each pitch originally assigned to each key in the right range When each pitch range is set to the left and right key ranges by shifting the pitch by 2 octaves (Oct) uniformly, the state of the keyboard after performing this (2) basic repetitive state setting process is Then, the state shown in FIG. However, FIG. 3B actually shows an example of the state of the keyboard when the first key division / sound range setting mode is selected when the continuous mode and song mode are selected. It does not indicate the state of the keyboard when this (2) basic repetitive state setting process is executed.

  In the above case, the ranges of the left and right key ranges are set to be completely coincident with each other. However, the present invention is not limited to this. May be generated. The “substantially the same” means this. In this embodiment, the keyboard has 88 keys with pitches from “A0” to “C8”, and the position “F4” is adopted as the “predetermined key range division position”. The 88 keys are divided into 44 keys each of “F4” or more (right key range) and “E4” or less (left key range). Of course, the key range division position is not limited to this, and it is sufficient that the number of keys is approximately the same in each key range. However, in the case of an 88-key keyboard, "A0" to "C4", "A4" A position where a sound range including “C8” can be secured in each key range is preferable.

  When the user does not set any further mode after switching to the continuous mode (when the continuous mode & non-song mode is selected), the CPU 5 advances the processing to the performance processing in the basic continuous state of (3). After that, this (3) performance process in the basic repetitive state is repeated (steps S4 → S5 → return → S1 → (S3 →) S4). In the flowchart of FIG. 6, the (2) basic repetitive state setting process is executed whenever the performance process in the (3) basic repetitive state is executed. However, since (2) the basic repetitive state setting process only needs to be executed once when the normal mode is switched to the repetitive mode, (2) the basic repetitive state setting process is bypassed, and from step S1. What is necessary is just to make it progress to step S4.

  In the performance process in the (3) basic repetitive state, when a key is pressed to the left key range, the CPU 5 generates a note-on event corresponding to the key pressed and supplies it to the left part of the sound source / effect circuit 11. Further, when the left pedal is operated, an operation event corresponding to the operation is generated and supplied to the left part of the sound source / effect circuit 11, while when the key is pressed against the right key range, the key is pressed. A corresponding note-on event is generated and supplied to the right part of the sound source / effect circuit 11, and when the right pedal is operated, an operation event corresponding to the operation is generated and the right part of the sound source / effect circuit 11 is generated. To supply. Here, “generating a note-on event and supplying it to the left part of the sound source / effect circuit 11” means supplying a note-on event with information indicating the left part to the sound source / effect circuit 11; “Generate a note-on event and supply it to the right part of the sound source / effect circuit 11” means supplying a note-on event to which the information indicating the right part is added to the sound source / effect circuit 11. The sound source / effect circuit 11 analyzes the supplied note-on event, and for the left part, the pitch information included in the note-on event is determined according to the range set for the left key range. After converting to a pitch, the musical tone parameter for generating the musical tone signal of that pitch is set in the corresponding register, while for the right part, the pitch information included in the note-on event is After conversion to a pitch corresponding to the pitch set in the right key range, a tone parameter for generating a tone signal of that pitch is set in the corresponding register. “To generate an operation event and supply it to the left part of the sound source / effect circuit 11” means to supply an operation event to which the information indicating the left part is added to the sound source / effect circuit 11, Is generated and supplied to the right part of the sound source / effect circuit 11 is to supply the sound source / effect circuit 11 with an operation event to which information indicating the right part is added. The sound source / effect circuit 11 analyzes the supplied operation event, and for the left part, a musical sound for adding a damper effect to the musical sound signal generated based on the note-on event in the left key range. While the parameter is set in the corresponding register, for the right part, the tone parameter for adding a damper effect to the tone signal generated based on the note-on event in the right key range is set in the corresponding register. . As described above, in the present embodiment, the pitch conversion and effect change for the key depression and pedal operation after the key range division are performed on the sound source / effect circuit 11 side. As in the case of generating the event and the operation event, that is, the note-on event and the operation event after the CPU 5 performs the pitch conversion and the effect change may be generated.

  Next, when the user selects the song mode while the continuous mode is selected, the CPU 5 advances the process to the (4) basic continuous state change process (steps S4 → S6). In this (4) basic reaming state changing process, first, the CPU 5 acquires the automatic performance data selected by the user from the storage location, and the automatic performance data storage area (not shown) secured at a predetermined position in the RAM 7. (Step S6). Next, the CPU 5 detects the range of the automatic performance data in the automatic performance data storage area (step S7). In the present embodiment, since the automatic performance data has the range information for each track, in the process of step S7, the CPU 5 reads the range information of each track of the automatic performance data and secures it at a predetermined position in the RAM 7. Stored in a range information storage area (not shown). When automatic performance data that does not have the range information for each track is selected, the CPU 5 checks the pitches of all the note events included in each track one by one, so that the range for each track. Is detected and stored in the range information storage area as the range information for each track. Further, when automatic performance data in which note events of a plurality of parts are mixed in one track is selected, the CPU 5 does not have the range information for each track after generating the note event for each part as described above. By the same process as the above process for detecting the range of automatic performance data, the range of each part is detected and stored as the range information of each part in the range information storage area.

  Next, the CPU 5 sets performance parts in the left and right key ranges (step S8). In the present embodiment, two types of performance parts are provided: a common part and left and right parts. And “setting a common part” means setting a part that is common to both the left and right key ranges, that is, setting both the left-hand part and the right-hand part. This means that a left-hand part is set in the left key range, and a right-hand part is set in the right key range. Whether to set “common part” or “part on left and right” is uniquely determined by the selected mode among the modes (M1) to (M3). Specifically, when either the (M1) or (M3) mode is selected, the “common part” is set, and when the (M2) mode is selected, the “left and right part” is set. Is set.

  Next, the CPU 5 sets the key range division position and / or the range in each key range according to the range detected in step S7 and the performance part set in step S8, and then the vicinity of the key at the key range division position. The LED provided in the LED is caused to emit red light, and the LED provided in the vicinity of the key at the center position of each of the left and right key ranges is caused to emit green light (step S9). Here, the setting of the key range division position and / or the sound range in each key range is also uniquely performed by the mode being selected among the modes (M1) to (M3).

  Specifically, when the mode (M1) is selected, the CPU 5 sets the key range division position to a predetermined position (in this embodiment, the center position of the keyboard), and the range information. It is determined whether the sound range indicated by the sound range information stored in the storage region belongs to a low sound range, a middle sound range, or a high sound range, and each sound range of the left and right key ranges is set to a sound range corresponding to the determination result. As described above, since the range information is detected for each track, the determination of which range the range belongs to is performed by checking the range information of all tracks (in this embodiment, 2 tracks). Needless to say, this is necessary. In this way, each range of the left and right key ranges is set to the middle range when the pitch range of the pitch information is the middle range (see FIG. 3B), and when the pitch range of the pitch information is the higher range. Is set to the high pitch range (see FIG. 3C), and is set to the low pitch range when the pitch range of the pitch information is the low pitch range (see FIG. 3D). Here, as shown in FIG. 3A, the low sound range is “C2” to “C5”, the middle sound range is “C3” to “C6”, and the high sound range is “C4” to “C4”. This is the range that mainly contains “C7”.

  On the other hand, when the mode (M2) is selected, the CPU 5 sets the key range division position to a predetermined position (in this embodiment, the center position of the keyboard) and stores it in the range information storage area. Among the recorded range information, it is determined whether the range indicated by the range information for track 1 (right hand part) belongs to the low range, middle range or high range, and the range of the right key range is determined according to the determination result Set to the range, determine whether the range indicated by the range information for track 2 (left hand part) belongs to the low range, mid range, or high range, and set the range of the left key range according to the determination result Set to. In the example of FIG. 4, since the range of the left hand part of the automatic performance data is “F2” to “F4” and the range of the right hand part is “C4” to “E6”, the left key range is the range of the left hand part. , That is, each pitch that was originally assigned to each key in the left key range is uniformly shifted up one octave, and the right key range is the range that includes the right hand part's range. In other words, the pitch range is set such that the pitches originally assigned to the keys in the right key range are uniformly shifted down by one octave.

  Further, when the mode (M3) is selected, the CPU 5 determines a key range including the range (corresponding to the number of keys) indicated by the range information stored in the range information storage region, and the key range is Set the key division position so that it is in the right key range, and set the range of that range information to the right key range, while comparing the range of the key range with the range of the range information for the left key range. Determine the range and set the range. In the example of FIG. 5, since the range of the automatic performance data is “F2” to “G6”, the key range division position is set to “F3”, and the right key range is the range “F2” to “G6”. , That is, each pitch that was originally assigned to each key in the right key range is uniformly shifted down by one octave, and the left key range is originally assigned to each key in the left key range. Each assigned pitch is set to a range that is uniformly shifted down by 2 octaves. In the present embodiment, the priority key range, that is, the range of the selected automatic performance data is wide, and if the left and right key ranges are divided approximately equally, neither key range can cover the range of the automatic performance data. When there is a concern, the right key range is adopted as the key range to which the entire range is preferentially assigned, because the student often plays the right key range. Therefore, when the student may play the left key range, it is preferable that the priority key range can be set to the right key range or the left key range. When a teacher teaches a student who plays a priority range by playing a key range that is not a priority range, that is, a range that cannot cover the range of the automatic performance data, the teacher replaces the octave ( For example, the currently set octave can be obtained by performing a performance with a pitch of “C6” by “C5” or by operating a predetermined operator included in the setting operator 2 as necessary. Try to play with appropriate settings.

  When the basic repetitive state is changed in this way, the changed basic repetitive state is written in the basic repetitive state storage area and supplied to the sound source / effect circuit 11. In response to this, the contents of the basic repetitive state storage area are updated, and the contents of the corresponding registers in the sound source / effect circuit 11 are also updated.

  Next, the CPU 5 performs a song reproduction process and a performance process in a repetitive state after changing the setting (step S10). Here, the song playback process includes a playback process that simply plays back the selected automatic performance data, a performance guide process based on the automatic performance data, and a performance according to the playback process or the performance guide process. A match determination process for determining a match with a performance performed by a user using a keyboard, a score display process based on automatic performance data, and the like are included. Note that the performance process in the repetitive state after the setting change is the same as the performance process in the (3) basic repetitive state. The reason is that in the performance processing, only note events and operation events are generated and supplied to the sound source / effect circuit 11 (therefore, there is no difference in processing procedure between the performance processing), and the musical tone parameters This is because all the processing for setting the value in each register of the sound source / effect circuit 11 is left to the sound source / effect circuit 11 side.

  In addition, since the process for switching the modes (M1) to (M3) is not described in the (4) basic reaming state change process, the mode switching is inevitably performed at another place (not shown). However, the present invention is not limited to this, and the mode switching may be performed in this (4) basic reaming state change processing. Whether or not the mode (M3) is selected depends on the range of the selected automatic performance data. That is, when the automatic performance data having a very wide range is selected, the mode (M3) is selected. Therefore, when automatic performance data having a very wide sound range is selected, the mode (M3) may be preferentially selected over the other modes (M1) and (M2). .

  In the present embodiment, the performance part of each key range is set by the process of step S8 in FIG. 6. However, the present invention is not limited to this. May be decided. In addition, in the present embodiment, the performance part is set separately when the song mode is selected. However, the present invention is not limited to this, and the performance part can also be set when the song mode is not selected. You may do it. In that case, either the left or right or both ranges are changed from the basic repetitive state.

  In this embodiment, in order to simplify the explanation, an example is shown in which whether or not the continuous mode is set first and then whether or not the song mode is set, and thereafter the mode cannot be changed. As a matter of course, the order of the setting of the continuous mode and the setting of the song mode may be reversed, and the mode may be arbitrarily changed in each mode.

  In the song mode, the key range division position and / or the sound range in each key range is automatically set. However, the user may be able to set whether or not to set automatically. When automatic setting is performed, a confirmation message such as “Would you like to set automatically?” May be displayed. Further, only the key range division position may be automatically set, or only the sound range may be set automatically. Further, after automatic setting, the setting may be changed by manual operation.

  Needless to say, the automatic performance data may be selected again in the song mode.

  Furthermore, in the present embodiment, the entire keyboard range is divided into two partial key ranges (left and right key ranges), but the number of divisions is not limited to “2”, but “3” or more. There may be.
