Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musical score recording/measuring device that automatically prints a musical piece played on a keyboard on print paper on which staffs are printed in advance.

An object of the present invention is to provide a music score printing device that can print a separate line along with the notes as necessary when printing the notes of a song played on a keyboard on print paper on which staffs are printed in advance. do.

According to this invention, a note length is detected in relation to a key pressed on a keyboard, and note information corresponding to the detected note length is sent to the generating means and key information specified in relation to a key pressed on the keyboard. shoulder line information generating means for generating primitive line information based on the musical note information and key information, when musical notes are printed on print paper on which staffs are printed in advance based on the musical note information and key information, and the basic line information is inputted, the KF
i K to print a separate line along with the note.

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 using a musical score printing 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 tone is automatically printed on a staff in advance. It is printed on printed paper.

Keyboard 1 generates key information (key code) KC indicating the pressed key in response to a key pressed on keyboard 1, and generates a key-on signal KON indicating whether or not the key corresponding to the code KC is pressed. do. For example, as shown in Table 1, the key code rKC is a 3-bit octave code B3+ill*Bt that represents an octave range, and a 4-bit note code N4 +Na +Na that represents the 12 note names within one octave.
This is a 7-bit binary coded signal expressed by IN and .

The first musical tone forming circuit 2 is the key tones generated from the keyboard l.
The FKC signal and the key-on signal KON form a K-based musical tone signal, and this signal is applied to the speaker 4 via the amplifier 3. From this K, the speaker 4 produces a sound corresponding to the key pressed on the keyboard L.

The autorhythm circuit 5 is used for automatic rhythm performance, and outputs rhythm sound signals indicating various rhythm instrument sounds to the differential 4 oscillator 6 in response to a rhythm selected by a rhythm selection switch (not shown) K. The TENI clock generated from the TCLK is generated in response to the TCLK. 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 l is applied to the note length detection circuit 7. The note length detection circuit 7 has the ten-four clock TCL added from the differential four oscillator 6 to other inputs, and generates note length data of the musical note by counting the tempo clock and TeL added during the middle-on time. Counting the ten-four clocks TCL added to the key-on signal generates the note length data of the rest. Note that this note length detection circuit 7 is configured to correct the count value when the count value includes an error and 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 1134, the note length data corresponding to the regular count value k so that it is output.

The note length data generated from the note length detection circuit 7 is applied to a note rest conversion circuit 8. Note rest information conversion circuit 8
outputs note rest information indicating a predetermined note L and rest based on the input note length data.Keep-FKC generated from the keyboard L is applied to the layer line information generation circuit 9. This layer line information generation circuit 9 generates the key code "KCK" based on the input key code KCK.
, detects whether the corresponding note requires addition 1lt-, and appropriately adds layer line information U1. U2゜Ll, generates 2. Note that the layer line information υl and U2 are separate line information corresponding to the upper - line and upper second line, respectively, and the leger line information L1
The work L2 is separate line information corresponding to Shimodate-i@Owork Shimodate 2liK, respectively. The key code KC input into the shoulder line information generation circuit 9 is a one-point C sound (center C sound) K
In the case of correspondence, the shoulder line information generating circuit 9 generates separate line information Ll. Furthermore, when the key code KC corresponds to the three-dot C note, the shoulder line information generation circuit 9 generates separate line information Ul and U2.
occurs.

The printer 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 addition 11AK based on the separate line information output from the separate line information generation circuit 9, and includes a 5-score of dot information corresponding to the note based on the key code KC. The printer IIK performs position control and outputs a control signal containing the above dot information to the printer IIK.

Printer IIH Based on this control signal, a musical score is printed on print paper 12 on which staffs are printed in advance.

Fig. 2 (1) shows the print paper 12 on which the staff is printed in advance and is sent to the printer 11, and Fig. 2 (1) shows a part of the print paper 12 on which musical notes are printed. be. FIG. 2(a) The note n indicated by K has note information corresponding to a quarter note, and separate line information Ll corresponding to the Shimodate-line and the Shimodate 2-line, as described above.

L2, which is printed on the print paper 12 when the key code KC corresponding to the hard A sound is applied to the printer control circuit 10.

In addition, in the above embodiment, the explanation was made assuming that the staff preprinted on the print paper is the staff of the treble clef staff.
This is not limited to this, but it can also be used for staffs on the bass clef staff. In this case, the shoulder line added to the treble staff and the separate line added to the bass clef staff have the note name indicated by the shoulder line. Because it is different, 7JOili
! The information generation circuit is a score! I! It is necessary to generate line information accordingly. Of course, the present invention can also be applied to print paper in which a staff representing a treble clef staff is printed on the upper row, and a five sheet representing a bass clef staff is printed on the lower row.

As described above, according to the present invention, when printing the notes of a musical piece played on the keyboard on print paper on which the staff is printed in advance, weights can be printed along with the notes as necessary.
