The color arrangement of the notes of the color score and the color arrangement of the notes displayed on the display 11 are the same as long as they are based on the same display information DT or DE.
[0031]
FIG. 2 is a conceptual diagram showing the format of the performance information MD according to this embodiment. The performance information MD is automatic performance information that conforms to, for example, the SMF (Standard MIDI File) format.
[0032]
In the header, information related to the entire performance information MD such as a data format type (SMF format O, 1) is usually recorded.
[0033]
The performance data RD is actual performance data for performing an automatic performance, and includes event data (hereinafter simply referred to as an event) and timing data (hereinafter simply referred to as timing) that is a timing for processing the event data. It is recorded. Note that, for example, the first measure of the performance data RD is data for setting various playback modes during playback of each part (track) as initial setting information, for example, tone color setting data, volume setting, etc. Data, tempo setting data, etc. are recorded.
[0034]
The timing TE is data representing the time for processing various events represented by the event data. The event processing time may be expressed as an absolute time from the start of performance or the start of a measure, or may be expressed as a relative time that is an elapsed time from the previous event.
[0035]
The event data is data representing the contents of various events for reproducing the music. The events include a note event (note event) NE representing a note directly related to the occurrence of music, which is a combination of the note-on event and note-off event shown in FIG. 2B, and a pitch change event (pitch bend event) (not shown). , A setting event for setting a reproduction mode of music such as a tempo change event and a tone color change event.
[0036]
In each note event, pitch, volume (velocity), etc. are recorded. The note event may be a note-on event having pronunciation length (gate time) data.
[0037]
FIG. 2A shows an example in which display information DT is embedded in the header HC of the performance information MD as described above.
[0038]
In this example, display information DT for determining the display mode of the note of each pitch name is recorded in the header HC. In the present embodiment, as the display information DT, a color table CT storing a plurality of pitch names and a color for displaying each pitch name is recorded.
[0039]
The pitch names recorded in the color table are pitch names within one octave, for example. In this embodiment, as shown in the figure, the pitch names (C, D, E... B) and the color schemes of the pitch names (red, yellow, green... Gray) are stored in association with the pitch names. . In the color table CT, note names of two octaves or more and colors corresponding to them can be recorded as necessary.
[0040]
Thus, when the display mode of the note of each note name is determined in advance and embedded in the header HC as the color table CT, common display information is transmitted throughout the entire song (the entire song represented by the performance information). (Color information).
[0041]
When the color table CT is embedded in the header HC, the display mode (color) for each note event cannot be controlled as in the example shown in FIG. The amount can be kept small. Also, the color scheme for each note name can be easily changed. For example, in a device having a color-coded keyboard with different color schemes, it is possible to easily change to a corresponding color scheme when playing back.
[0042]
Also, by embedding the color table CT of this embodiment as display information DT in the header of existing performance information, performance information MD having the display information of this embodiment can be created very easily. That is, by using the color table CT corresponding to the color arrangement of the color-coded keyboard owned by the user, it is possible to easily create performance information MD having display information corresponding to the device owned by the user. In addition, when the user has a keyboard whose display mode (color arrangement) can be changed, the color arrangement of the keyboard desired by the user is very easily achieved by using the color table CT of the user's desired color arrangement. The color scheme can be changed. The color table may be stored at the head of the performance data portion instead of the header HC that is distinguished from the performance data portion. Also in this case, it can be considered that it is actually stored in the header.
[0043]
FIG. 2B shows an example in which the display information DE is recorded as event data for each note event NE in the performance data RD.
[0044]
As shown in the figure, for each note event NE, the display mode (color) of the note name corresponding to the note event is designated at the same timing TE ′ as the timing TE of the note event. For example, the display information (red) DE is recorded at the same timing TE ′ as the timing TE of the note event (C) NE that instructs the pronunciation of the note name “C”. Here, if the data is described in absolute time at the timing, TE = TE ′, and if it is described in relative time, TE ′ = 0. Is also good). In this way, it is possible to individually specify colors for all the note events recorded in the performance data RD. Either the note event or the display information may be arranged before or after.
[0045]
In the above-described two examples, an example in which color name information such as “blue”, “yellow”, and “green” is given as the display mode (color information) is shown, but a simple numerical value or symbol corresponding to the color name may be used. (For example, blue = “1”, yellow = “2”, etc.). Alternatively, for each color of RGB, color information may be provided by luminance information indicating luminance at a predetermined level (for example, 8 levels, 256 levels, etc.). In this way, each display device can surely reproduce the same color. Further, the luminance of the color information can be changed according to the volume of each note event NE or the tempo set in the performance information MD.
[0046]
The black keys may be all black, or may be the same color as the white keys and a slightly darker color (for example, C # is dark red). Alternatively, a completely different color may be designated.
[0047]
The color scheme of each note name may be different for each piece of performance information. Thereby, the color can be changed according to the level, such as a color for beginners, a color for intermediates, and a color for advanced users. Alternatively, when the color scheme differs depending on the type of keyboard device, display matching with the keyboard device is possible by selecting performance information in which an appropriate color is set for each type of keyboard device (for example, keyboard device) A performance information for A, performance information for B, etc. are prepared separately). Alternatively, a plurality of different color setting information may be included in the performance information, and appropriate color setting information may be selected for each type of keyboard device.
[0048]
Further, performance information MD combining the above two examples may be created. In this case, a default color scheme is designated in the color table CT of the display information DT in the header HC, and notes or the like are displayed in a color different from the default color scheme by the display information DE individually or temporarily. It becomes possible.
[0049]
FIG. 3 is an example of display of performance contents based on the performance information MD according to the present embodiment. In the present embodiment, the performance contents are displayed based on performance information (note events) for instructing pronunciation. Of course, the pronunciation based on the performance information may be performed together with the performance content display. Actually, each note is displayed in color, and each key is illuminated or colored with color light. In the figure, the color portion indicates the color scheme in parentheses at or near the location. Moreover, although the figure shows an example in which the display device (display) and the keyboard are integrated, an individual display and keyboard may be used.
[0050]
On the display 11, a performance content (music score) display 111 and a determination result 112 are displayed. The determination result 112 can be omitted when the performance determination is not performed.
[0051]
The performance content display 111 displays, for example, a note 111n corresponding to the note event NE of the performance data RD (FIG. 2) on the staff. The current position of the performance data RD is indicated by a line pt representing the current position. Next, a pointer nn is arranged on the note 111n to be played by the user. In addition, fingering information FN can be displayed on each note 111n. For example, the fingering information FN displays the number corresponding to each finger in the same color as the corresponding note 111n. Note that the fingering information FN may be omitted.
[0052]
The musical notes 111n move from right to left as time passes, as indicated by the dashed arrows. Each note 111n is displayed in a color (green, blue, purple, orange, etc.) written in parentheses under each note. This display color (color arrangement) is indicated by, for example, the color table CT of the display information DT in FIG. 2A or the display information DE in FIG.
[0053]
The determination result 112 displays the determination result of the user's performance level determined by the comparison determination unit 51 described later.
[0054]
The color-coded keyboard 15k has keys illuminated or colored in the same color scheme as the display information DT or DE included in the performance information MD (the same color scheme as the musical notes 111n), and performance signals (note event NE) corresponding to the operation of each key. ) Is output. The user refers to the performance content display 111 displayed on the display 11 and operates a key having the same color as the note 111n to be played.
[0055]
When the performance operator 15 includes an RGB light emitting diode (light emitting unit) 15L, each key (white key) of the color-coded keyboard 15k is white, and the performance information is obtained by the light from the light emitting unit 15L. It becomes the same color scheme as the display information DT or DE included in the MD (the same color scheme as the note 111n).
[0056]
The light emitting unit 15L is composed of light emitting diodes of at least three colors (RGB), and irradiates the key of the keyboard 15k with light of the color indicated by the display information DT or DE included in the performance information MD. The luminance and the like of the light emitting diodes of the respective colors are controlled by the light emission control circuit 23 of FIG. 1 based on the display information DT or DE.
[0057]
The display of the performance content is not limited to the score display, and any display is possible as long as the performance content can be displayed visually, such as a piano roll display. In that case, the display corresponding to each note (note event) is displayed in the color scheme corresponding to the display information DT or DE.
[0058]
FIG. 4 is a functional block diagram showing an example in which a performance practice function is added to the performance content display device 1 of the present embodiment. In this example, a keyboard device 15 having a light emitting unit 15L (FIG. 3) is used.
[0059]
The performance information MD is stored in, for example, the external storage device 7 in FIG. 1 and is read out to a buffer prepared in the RAM 3 or the like according to a user instruction. The read performance information MD is supplied to the display unit 111, the color-coded keyboard device 15, and the comparison determination unit 51.
[0060]
The display unit 111 displays performance contents based on the supplied performance information MD, for example, as shown in FIG. The user refers to the performance contents displayed on the display unit 111 and operates the color-coded keyboard device 15 to perform the music. Based on the supplied performance information MD, the color-coded keyboard device 15 irradiates the key with color light with the same color scheme as the performance content displayed on the display unit 111. The color-coded keyboard device 15 generates a performance signal in response to a user's performance operation, and supplies the performance signal to the comparison / determination unit 51.
[0061]
The comparison / determination unit 51 compares the note event NE of the supplied performance information MD with the performance signal (note event) supplied from the color-coded keyboard device 15 to determine whether or not they match. For example, if they match, a score (point) is added, and if they do not match, points are deducted (or nothing is done). The determination result (score) here is supplied to the result display unit 112 and displayed. Note that the determination result of the performance of the user may be calculated in consideration of not only the coincidence / non-coincidence of the note events but also the operation timing shift, velocity, aftertouch, and the like.
[0062]
FIG. 5 is a flowchart showing an example of a performance content display process according to this embodiment performed by the CPU 5 of FIG. In the following two flowcharts, timing data is not taken into account, but in practice, the rhythm of notes may be determined based on the timing data. It is also necessary to consider.
[0063]

[0064]
In step SA1, the performance content display process is started, and in step SA2, the display information DT embedded in the header of the performance information MD is read out to a buffer or the like. In step SA3, the color table CT of the display information DT read into the buffer is set as a display table. Thereafter, the display mode of the performance content is determined with reference to this display table.
[0065]
In step SA4, the note event NE at the current timing is read from the performance information MD. In step SA5, with reference to the display table set in step SA3, the display mode (for example, color scheme) of the performance contents (for example, notes, fingering information, etc.) corresponding to the note event NE read in step SA4 is determined. . In step SA6, the performance content corresponding to the note event NE is displayed on the performance content display unit 111 of the display 11 based on the display mode determined in step SA5. Alternatively, the performance contents and the display mode thereof are supplied to the printer output circuit 21. The printer output circuit 21 generates data for printing a musical score based on the supplied information.
[0066]
In step SA7, it is determined whether or not the music corresponding to the performance data MD has been completed. If it is determined that the process has not been completed, the process returns to step SA4 as indicated by a NO arrow. If completed, the process proceeds to step SA8 indicated by an arrow “YES” to end the performance content display process.
[0067]
If a plurality of display information DT is recorded in the header of the performance information MD, a step of selecting one display information from the display information DT is provided.
[0068]
FIG. 5B is a flowchart when the performance information MD shown in FIG. 2B is used.
[0069]

[0070]
In step SB3, the display information DE corresponding to the note event NE read in step SB2 is read from the performance information MD, and the display mode of the performance content corresponding to the note event NE is determined.
[0071]
In step SB4, the performance content corresponding to the note event NE is displayed on the performance content display unit 111 or the like of the display 11 based on the display mode determined in step SB3. Alternatively, the performance contents and the display mode thereof are supplied to the printer output circuit 21. The printer output circuit 21 generates data for printing a musical score based on the supplied information. A note is displayed based on the determined display mode.
[0072]
In step SB5, it is determined whether or not the music corresponding to the performance data MD has ended. If it is determined that the process has not ended, the process returns to step SB2, as indicated by a NO arrow. If completed, the process proceeds to step SB6 indicated by an arrow “YES” to end the performance content display process.
[0073]
