Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musical score display device that automatically displays nine pieces of music played on a keyboard on a display section on which staffs are displayed in advance.

It is an object of the present invention to provide a musical score display device that can display layer lines along with the notes as necessary when displaying the notes of nine pieces of music played on a keyboard on a display section on which staffs are displayed in advance. purpose.

and shoreline information generating means for generating square line information based on key information specified in relation to key presses on the keyboard,
Based on the note information and key information, notes are displayed on a display section on which staffs are displayed in advance, and when the square line information is input, layer lines are displayed together with the notes.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of an electronic musical instrument having a musical score display device according to the present invention, in which a musical tone is generated based on a key pressed on a keyboard 1, and the musical staff is automatically displayed in advance. It is displayed on the display section that is displayed.

Keyboard l is key information that indicates the pressed key corresponding to the key pressed on keyboard l @
(Key code) KC and a middle-on signal KON indicating whether or not the key corresponding to the key code C is pressed is generated. Key code KC is, for example, a 3-bit octave code B that represents an octave range as shown in Table 1.
Hatakem! Is e Bs and a 4-bit note code representing the names of the 12 notes within one octave N4 e Nl
This is a 7-bit binary coded signal consisting of e Nl e Nl .

The first musical tone forming circuit 2 forms a musical tone signal based on the key code KC and key-on signal KOH generated from the keyboard 1, and applies this signal to the speaker 4 via an amplifier 3'f. As a result, the δ speaker 4 produces a sound corresponding to the key pressed on the keyboard 1.

Further, the autorhythm circuit 5 is used for automatic rhythm performance, and a tempo oscillator 6 generates rhythm sound signals indicating various rhythm instrument sounds in response to a rhythm selected by a rhythm selection switch (not shown). Occurs depending on the tempo clock and TCL. This rhythm sound signal is also amplified by the amplifier 3 in the same manner as described above, and is emitted by the speaker 4 as a rhythm sound.

On the other hand, the key-on signal KON generated from the keyboard 1 is applied to the note length detection circuit 7. The note length detection circuit 7 receives the tempo clock TCL from the tempo oscillator 6 to other inputs, and generates note length data of the note by counting the tempo clock and TCL added to the key-on time, and adds it to the key-off time. Rest note length data is generated by counting the tempo clock and TCL. Furthermore, this note length detection circuit 7 is configured to correct the count value when the count value includes an error, and to generate note length data corresponding to the corrected count value. In other words, when the regular count value corresponding to a quarter note is, for example, 32, even if the actual count value does not match the regular count value, such as 30 or 34, the note length data corresponding to the regular count value is It is now output.

The note length data generated from the note length detection circuit 7 is a note rest:
It is added to the ns converter circuit 8. The note rest information conversion circuit 8 outputs note rest information indicating predetermined notes and rests based on input note length data.

Further, the key code KC generated from the keyboard 1 is applied to the tightening information generating circuit 9. Based on the input key code KC, this tightening information generating circuit 9 detects whether the note corresponding to the key code KC is added at-necessary or not, and generates the tightening information Ul, U2゜Ll, L2 as appropriate. Occur. Note that the training information U1 and U2 are leger line information corresponding to the upper first line and the upper second line, respectively, and the shoreline information L1 and L2 are shoreline information corresponding to the lower medicine line and the lower medicine second line, respectively. . Therefore, when the key code KC input to the shoreline information generating circuit 9 corresponds to one point (center input tone) K, the shoreline information generating circuit 9 generates the shoreline information Ll. Also,
When the key code KC corresponds to a three-point tone, the shoreline information generating circuit 9 generates shoreline information U1 and U2.

The display control circuit 10 is a read-only memory (ROM) that outputs dot information corresponding to a predetermined note rest based on the note rest information output from the note rest information conversion circuit 8.
, includes a ROM etc. that outputs dot information corresponding to a predetermined tightening based on the shoreline information output from the shoreline information generation circuit 9, and controls the position on the staff of the dot information corresponding to the note based on the middle chord KC. A control signal containing the above dot information is output to the display 11. The display unit 11 has a staff printed in advance on its display section 11m, and displays the musical score on the display section 11m on a liquid crystal display based on the control signal. Further, when a new note group is displayed on the display section 11m, each note is shifted to the left one by one along with the display of this note. Note that the musical score display is not limited to a liquid crystal display, and various other displays such as a light emitting diode display and an electroluminescent display are possible. Furthermore, when shifting the notes to the left, the notes may be shifted in units of measures every time one measure ends.

FIG. 2 shows an example of the display section 11m on which musical notes are displayed. As mentioned above, the note n shown in FIG. 2 includes note information corresponding to a quarter note, shoreline information Ll, L2 corresponding to the laxative line and laxative second line, and Φ- corresponding to the Kataka C6 A note. When code KC is applied to display control circuit 10,
This is displayed on the display section 111.

Although the above embodiment has been described assuming that the staff preprinted on the display section is a staff on a treble clef staff, the present invention is not limited to this, and may be a staff on a bass clef staff. In this case, the crimping added to the treble staff and the crimping added to the bass clef are rounded off with different names indicated by the kaku, and the shoreline information generation circuit needs to generate shoreline information according to the staff. There is. It goes without saying that the present invention can also be applied to a display section in which a staff showing a treble clef staff is printed on the upper row, and a five-line sheet showing a bass clef staff is printed on the lower row. Further, the staff displayed on the display unit may be displayed when the power is turned on.

As explained above, according to the present invention, when displaying the notes of a song played on the keyboard on the display section on which the staff is displayed in advance, it is possible to display the caulking along with the notes as necessary.
