DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a musical score output device that automatically displays a musical score on a staff when played on a keyboard.

SUMMARY OF THE INVENTION An object of the present invention is to provide a musical score output device that can distinguish and display the musical notes for each part when playing a keyboard and displaying the musical notes of nine or more parts on a staff.

According to this invention, in a musical score output device for an electronic and electrical appliance in which a keyboard is divided into a plurality of key ranges [7] and different parts are played depending on the divided keyboard, each part is Par LjlK A note information generating means is provided which detects the pitch and note length and generates key information corresponding to the pitch and note information corresponding to the note length, and generates notes for each part based on the key information and note information. In addition, the directions or colors of the note O stems are displayed differently.

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 appliance having a musical score output device according to the present invention, which generates a collected sound based on a key pressed on a keyboard L and automatically outputs a music score output device to a staff Kl.
! It is meant to show.

The keyboard 1 generates key information (key code) KC indicating the depressed key and a mid-on signal KON indicating whether or not the corresponding key is depressed. For example, the key code IC is a 3-bit octave code that represents the octave range as shown in Table 1.
l + J e Bl and 4-bit note code representing Minoru's note name within one octave N4 m Na t N
This is a 7-bit binary code consisting of a, e, and N1.

//' The key code KC and key-on signal KON generated from the first keyboard 1 are applied to the octave control circuit 2.

The octave control circuit 2 controls the octave code 'l of the key code KC input according to the operation state of the selection switch 3.
e J t B1 is controlled according to the key range of keyboard l, and when signal @1'' is applied from selection switch 3,
The keys of the keyboard L are divided into two, and the octave code "S + "t + "I is controlled so that the octave codes "l+Bl+"l of the pressed keys at the same position in each key range match. In other words, the octave code "S + "t + "I is The octave codes B, il□L of the leftmost key and the leftmost key of the right key area are made to match.

The distribution circuit 4 divides and outputs the medium code KC and key-on signal KON input from the octave control circuit 2 to output terminals Q1 and Q2 as appropriate according to the operation status 11 of the selection switch 3. Signal @1”
is applied to the input terminal Q1, the Imaichi code IC and key-on signal NON are output from the output terminal Q1, and the signal @"'1 is outputted from the output terminal Q1.
When ' is applied to input terminal B, key code KC and key-on signal KONt are output from output terminal Q2, and when signal 11'' is applied to input terminal C, 2-key range O is output from octave control circuit 2. Key code KC and key-on signal KONvr output terminal Ql for each key range
The data is divided into 92 parts and output as one output.

Here, the movable contact piece 31 of the selection switch 3 is the contact 3bK*
We will explain the case where the wire is threaded. In this case, the octave control circuit 2 does not operate, and the key code KC and key-on signal KC generated from the key 111 are transmitted to the tone forming circuit 5 and the first part via the octave control circuit 2 and the output terminal Ql of the distribution circuit 4. It is added to the note detection section 6.

The musical tone forming circuit 5 forms a musical tone signal based on the input key code IC and key-on signal KOH, and applies this signal to the speaker 8 via the amplifier 7.

As a result, the sound corresponding to the key pressed on the Subinika 8-Hiro keyboard 1 is produced.

The autorhythm circuit 9 is used for automatic rhythm performance, and the tempo oscillator 10 generates rhythm sound signals representing various rhythm instrument sounds in response to a rhythm selected by a rhythm selection switch (not shown). It is generated in accordance with the tempo clock TCL. This rhythm sound signal is also amplified by the amplifier 7 in the same manner as described above, and is emitted by the speaker 8 as a rhythm sound.

On the other hand, the first part note detection section 6 has a note length detection circuit 61 and a note rest information conversion circuit 62, and has a key-on signal K of the input key code KC and key-on signal KON.
ON is applied to the note length detection circuit 61. Note length detection circuit 6
1 is the tempo clock T from the tempo oscillator lO to the other input.
A tempo clock TCL'i added to the key-on time generates note length data by counting the tempo clock TCL'i added to the key-on time, and a tempo clock TCL'i added to the key-off time
By counting to CL1, note length data of the rest is generated. Note that this note length detection circuit 61 is configured to correct the L 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 (quarter note) or U, the note length corresponding to the regular count value Data is now output.

The note length data generated from the note length detection circuit 61 is added to the note rest information conversion circuit 62. The note rest information conversion circuit 62 outputs note rest information indicating a predetermined note and rest based on input note length data.

This note rest information is applied to the key codes KC and 4 input to the first part note detection section 6, and to the display control circuit 11 and printer control circuit 12, respectively.

The display control circuit 11 is a read-only memo IJ (1!OM) that outputs dot information corresponding to a predetermined note rest based on the note rest information output from the note rest information conversion circuit.
Write a song and enter the key code l [cK based I! The position of the dot information corresponding to the note on the staff is controlled, and a control signal containing the dot information is output to the display 13.

The display unit 13 displays the staff, the treble clef, and the vertical line on the liquid crystal display when the display unit 13aK is powered on, and displays the musical score on the display unit 13a based on the control signal. Note that when a new note is displayed on the display section 13a, each note is shifted to the left by 1') along with the display of this note. In addition, the musical score display is not limited to a liquid crystal display, but can be displayed using a light emitting diode or an electroluminescent display. When shifting the notes to the left, it may be possible to shift the notes in units of measures at the end of each measure.

Further, like the display control circuit 11, the printer control circuit also outputs a printer control signal as appropriate based on the note rest information and key code KC output from the first part note detection section 6, and the printer 14 controls this printer. The musical score is printed on the print paper 14m based on the signal 1. Next, the movable contact piece 3a of the selection swifter 3 contacts the contact point 3CKil.
This section explains the case where the connection is continued. In this case as well, the octave control circuit 2 does not operate as described above, and the key code KC and key-on signal KON generated from the keyboard l are transmitted to the musical tone forming circuit 5 and The second part is added to the note detection section 15.

The musical tone generation circuit 5 forms a musical tone signal based on the input key code KC and key-on signal KOH, and applies this signal to the speaker 8 via the amplifier 7.

As a result, the sound corresponding to the nine keys pressed on the Spinica 8ri keyboard L is produced.

Further, the tuna 2 part note detection unit 15 has the same enclosure structure as the 9th part note detection unit 6 described above, and detects note rest information and - applying code KC to display control circuit 11 and printer control circuit 12, respectively;

The display control (b) path 11 and the printer control circuit 12 are
When -C is input to the note rest information and key code from the 1g2 bat note detection unit 15, when outputting the 9 control signal described above, in order to invert the note, that is, the note g of the note
A control signal corresponding to the note is output so that the o direction is downward tIK.

As a result, notes with downward stems are displayed on the display section 13a and printed on the print paper 14a.

Next, a case will be described in which the movable contact piece of the selection switch 3 is connected to the contact point 3d. In this case, the octave control circuit 2 inputs a key code KC according to the key range on the keyboard 1.
Controls the octave code Bl v"t+"l, and divides the key code IC and key-on signal of the 2-key range added from the octave control i road 2 from the output terminals Ql and Q2 for each key castle. The musical tone forming circuit 5 forms a musical tone signal based on the input two sets of key codes KC and key-on signal KOH, and applies this signal to the speaker 8 via the amplifier 7. Accordingly, the speaker 8 produces sounds corresponding to the keys pressed in each key range on the keyboard l.

On the other hand, the first part note detection section 6 receives the key code KC and the key-on signal KO which are also added to the output terminal Q1 of the distribution circuit 4.
Based on N, the above-mentioned note rest information and key code tC are sent to the display control circuit 11 and printer control respectively.
In addition to path 12, the second part note detection section 15 similarly outputs note rest information and key code KC based on the key code KC applied from the output terminal Q2 of the distribution circuit 4 and the key-on signal KONK to the display control circuit 11 and printer control respectively. Add to circuit 12.

As a result, the display control circuit 11 and printer control (b) path 12 output control signals related to the two parts to the display 12 and printer 13, respectively, and the display 13 and printer 14 output the stem of the note for each part. Notes relating to the first part are displayed with their stems facing upward, and notes relating to the second part are displayed with their stems facing downwards.

FIG. 2 shows an example of a print sheet 14J1 on which musical scores of two parts are printed by the printer 14. As is clear from FIG. 2, according to the present invention, musical notes representing two parts are displayed in a clearly distinguished manner for each part.

e. Alternatively, there may be one heart note detection section and this may be used in a time-sharing manner. In this case, it is necessary to add a flag signal indicating the first and second parts to the output of the distribution circuit. In the above embodiment, the directions of the stems of the notes are displayed differently for each part, but the present invention is not limited to this, and it is also possible to display or print the notes in multiple colors for each part.

As described above, according to the present invention, when playing the keyboard and displaying the notes of a music with nine or more parts on a staff, the notes can be displayed separately for each part.
