Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a movable keyboard instrument such as a piano, an organ, a reed organ, etc., each equipped with an appropriate number of indicators for displaying the pitch and length of the note. This invention relates to a semi-automatic performance device for a keyboard instrument, which is mounted on a display panel and performs according to instructions on a display on a movable display panel. Pianos and other keyboard instruments have been equipped with electronic computers that store memorized musical notes, and have been made to automatically play musical notes stored in i1mK memory. There is the inconvenience of not being able to play the piano.

When a keyboard instrument K plays a melody and accompaniment chords, a chord or chord display device designed to indicate only the key of the chord is known, for example, from Ewachi No. 49-42169. This cor-P! The I display device consists of a number switch that is driven by each melody key when it is operated, and a switch that is connected to a vertical line.
The IJx circuit and the output line of this matrix circuit are connected to each other, and the matrix circuit is equipped with an indicator light corresponding to each pitch K of at least one octave, which lights up when the output line is output, and the matrix circuit is connected to the output line of this matrix circuit, and is equipped with an indicator light corresponding to each pitch K of at least one octave. When the melody switch is activated, the indicator light of the chord key corresponding to the pitch of the melody key is turned on.

Although this display device allows the right hand to play a melody with single notes, it is difficult to play the chords that match the melody with the left hand, so this display device displays only the chords to be played with the left hand arranged in correspondence with these keys K. It was designed to be illuminated by a light.

This display device must be able to play at least the melody while looking at the music, so it cannot be used by people who cannot read music or who cannot match the keys to the notes. While playing the melody part, the accompaniment section's li! It is very difficult to find the indicator lamps and hit the keys. 't! The difficulty becomes even greater when hitting two or more keys at the same time as a chord.

The present applicant proposed a semi-automatic performance device for keyboard instruments to solve this defect (4I Application No. 121427/1982). Sakiho's semi-automatic performance device is a keyboard instrument that uses one key for each key needed to play the melody part of a certain piece of music.
Combining two displays, you can enjoy all the @!
Automatic keystrokes 1-9 are combined with each of the automatic keystrokes 1-9, and the Enshunkan sequentially hits the keys corresponding to the notes in the melody part according to the display on the front panel, thereby automatically hitting i! The devices are energized one after another and the accompaniment sections are automatically played at the same time.

In the semi-automatic performance apparatus according to this prior application, the player only has to press the keys in accordance with the front and back keys of the display, and can play with only the eight fingers, for example, so it is not possible to learn the cursive fingering method.

Il! When practicing the 4K piano, a board instrument, the fingering method is set to special Kllgk, and when the 415 fingers are assigned to, for example, one octave of keys, for example, in the case of the right hand, the thumb is the "C" note K1, the index finger is the "2" note K The key that each finger should press is determined. Therefore, although the above-mentioned patent application has brought about excellent improvements over the known techniques in terms of learning notes and other aspects of piano practice, it is inadequate in terms of learning fingering methods, and it is not suitable for all display devices. This made it unsuitable for piano practice because one's arm could not follow the display, and the disadvantage was that it was expensive.

The present invention has this point! In order to improve the K, we have incorporated a movable display board K that covers the range that can be played with the five fingers of the hand, for example, an octave. When the next note falls outside the indicated range of the movable display board, the movable display board will move the required distance, for example, one octave, and will be displayed on the vkK display, and the hand will move according to the board. If an automatic key-pressing device and its energizing device are installed,
This is so that either the melody section or the accompaniment section is automatically played. Next, a first embodiment of the present invention will be described in which the semi-automatic performance device of the present invention is attached to an 88-key piano and the performance notes are played according to the instructions on the note insert.

In response to a switch state detection circuit 90 and a detection circuit 90K for detecting a keystroke, depression, or release of a key, the melody part stored in the storage device 14K is simultaneously played. A drive circuit 8o is arranged to operate the light emitting diodes awh of the note display bodies 16-1 to 16-8 so as to sequentially display the binary code information of the notes from the storage device 14 during performance. At a certain point in time, the key corresponding to the next note is displayed on the eight display bodies 16-1 to 16-8, 16'-1 to 16'-8 on the movable display boards 16 and 16'.

The interface circuit 12, the control circuit l3, the switch circuit 13', and the storage device 14 form an integral component of a small electronic computer, and a piano K is attached to the interface circuit l2. The conductor for the priority and from the control circuit l3 are connected to the movable display boards 16, 16'.
The connection cords to the bottom surface 23 of the holder are pulled out respectively.

Next, with reference to Figures 3A to 3D of K, a description will be given of a case in which the element sensor detects, for example, the depression of a key t in the melody section or the release of a key t that has been depressed.

Although FIGS. 3a to 34 show one note attenuator 16-lK of the movable display board 16, other note attenuators 16-2 to 16-8' of the movable display board 16 and the movable display board 16' are shown. The musical note display bodies 16'-1 to 16'-8K also have the same configuration as that of the same machine. The part surrounded by the dotted line in K1 in Figures 3a and ab corresponds to the switch Sl in Figure Igra, and is an optical sensor type or magnetic sensor type non-contact switch assembly that can be attached and detached from the socket K on the board as a single unit. The same applies to 82 to S8 (switches similar to switches 81 and 8g may be attached to all m used for performance). Ilg 3 a s 3 6 is an explanatory diagram of the principle of Jin's contactless switch assembly, and each one is the third axab.
Corresponding to FIG. κ, the state before and after the player presses a certain white key 15 is shown, respectively.

The current from the 1 m source passes through the light receiving diode rPD2 and is grounded, and no control signal is sent to the switch state detection circuit 90K of the control circuit l3 (switch 81 is closed). When the key 15f is pressed down to nK as shown in #I3b, . light emitting diode P

The control circuit l3 shown as a block in FIG.
The main character of the series continues.

Since the switch 81 opens when the key is pressed and closes when the key is released, the third c. The pressure at the connection point J in Fig. 34 changes from the instantaneous gate KFiOV of pressing down to 5v, and from the instantaneous gate KFiOV of releasing 5v to OV. Therefore, when the switch state detection circuit 90 detects the positive transition state of the control signal, the κ control signal -r

Qin@K, which represents a musical instrument, uses various symbols such as the treble clef, notes and rests, dotted notes, speed signs, dynamics, and ideas. , this circle is the most,
The basic elements are musical notes that represent the length of a note and the length of the note.

The note K is a whole note, a half note, and a 4 note to represent the length of the note.
Diameter note, 8th note, 16th note, 32nd note, ζ
As is well known, this is represented by the letter K, which looks like a letter K. This is visually displayed by selectively emitting light from the eight light emitting diodes shown in FIG. 41K in a predetermined combination K. That is, for whole notes, only light emitting diode b is used, and for half notes, light emitting diode b% f, 4

Fi has a different ring shape around it. Similarly, other diodes c -%- h are K# in the K resin molded body.
There is a l-included housing. Eight lead terminals and a 10B voltage terminal (to be described later) are drawn out from each of the light emitting diodes 1 to h as shown in the figure, and connected to the control circuit 13Kli. Selectively κ driven. g%h is a light emitting diode representing a dotted note. In this example, the level Fi14 with different lengths of sounds.
4 bits of Ktj binary are required to specify one of these. Since the number of note indicators is Fi8, we need a binary 3-bit system to specify this.

When displaying the pitch and duration of one note K, the total number of pits for one note is 4+3-7♂k.

If, for example, five notes are set to be played at the same time in the melody section, these notes will be played at the same time. ! ! Since it is displayed in 16-1-16-8K, the required number of bits is 3 x 5 + 4 = 19 bits K (in this case, the length of each note is the same). Next K-Essence Figure 5a and 6th

Figure K shows eight display bodies 16-1 to 16-8, two circles 16-
Only 1% l6-8 is shown.

To explain only the display body 16-1, the drive circuit 80
One of the eight conductors at the lower end of the circuit passes through a diode Set with the polarity shown, and the pace Kl! of the transistor TRI! continued,
The point between the diode 50 and the pace of the transistor TR1 is connected to the transistor TRl through a noise resistor 51t-.
It is connected to the conductor that connects the and 10B power supply. The conductor aIIi is connected to K so that all the transistors TRI and TR8K are common as shown in the figure.

A total of eight conductors 41Fi at the bottom of the drive circuit 80 are key position designation parts, and upon detecting the depression of a key corresponding to a certain note in the melody part, the control circuit 13 determines the next note in the accompaniment part. When the key position Vt is detected, the κ voltage is applied only to the conductor corresponding to sK selected by this reading, and for example, the transistor TRl becomes conductive.

In FIG. 6, the cathode sides of the light emitting diodes a to h of the display body 16-1 are each connected to a resistor Rl. 〜R1ht− is connected to the collector K of 8 factory grounded transistors 41, and the transistor 41
The pace potential of is controlled by the control H path 13K. - When one circuit l3 selects the symbol body 16-1, the control circuit [1

Only the light emitting diodes a%f up to -1%f'-1 emit light to display ζ, which is a quarter note. As a result of this, a quarter note is displayed on the display 16-IK in FIG. Press down for 1 second. Note that this pressing time is not limited to 1 second K, but can be set to any appropriate time desired by the performer.

If instead of displaying the shapes of musical notes (8 light emitting diodes a-hK), a combination of light emitting diodes or lamps D1 to D8, one for each key of K1, is used as an indicator, the circuit of Fig. 5a is used. For IK, the circuit of FIG. 5b is used.

Although the following explanation will be made regarding the display device with the movable display plate 16K attached, the movable display plate 16'K has exactly the same structure. In FIG. 5b K, the indicator consists of one light-emitting diode or lamp DI,n6 in place of the light-emitting diodes a to h, and the anode of the light-emitting diode D l -D @ is a +B% source. The cathode is connected to the collector K of the transistor T R/l -'r R'8, and the cathode is connected to the collector K of the transistor T R/l -'r R'8.
The '80 paces are connected to the terminals T'l to T/a of the control circuit l3 through diodes of the polarities shown in the figure, respectively. When the control circuit l3 detects the depression t of a key corresponding to a certain note K in the melody part, it reads out the key position of the note corresponding to the next note in the melody part from the storage device l4, and inputs the corresponding terminal ('[ '/x~T/s, for example, T
'8) Increase the voltage by +24VK from Ov, for example.

As a result, a pace voltage is applied to the pace K of the transistor TR8, the transistor TRfiFi becomes conductive, and the light emitting diode D8 lights up, indicating the position of the key to be pressed next. In this case, the length of the note is not displayed, but if it is a Hata piece that the performer is familiar with, the player presses the designated key for an appropriate amount of time. Control circuit 1311
When this depression or release of the depressed key is detected, reading of the next note is started as described above as follows. However, the diode can also be flashed at a specific frequency to indicate the length of the note. In this case, K is also designed so that the note type is coded into 4 pits, and the control circuit 13 reads out the encoded information and causes it to blink at different blinking cycles.

As described above, in order to help students learn fingering methods that are important in piano practice, the present invention is designed to have movable display boards 16 and 16' for the right and left hands slidably mounted in the left and right directions, so that the right hand and the left hand can freely slide. and left hand position on these display boards 16,1
6' as shown in FIG.

The display boards 16 and 16' are placed side by side on the leftmost side of the piano, for example, except during performances. This is a semi-automatic musical instrument.
By moving it with your hand when you cut the s, you can also create a program that sets the leftmost f on the 11 piano on the Kll display at the end of the performance of one piece. Realized. Movable display board l6, 1 6
' are respectively 8 display bodies 1 6-1 to l6-8, 1
6'-1 to 16'-8, and the distance between adjacent display bodies (distance between the center line of one display body and the center line of the next display body) is the distance between adjacent keys (1 The distance α) between the center line of one key and the center line of the next key is determined by K. That is, the center line of each front body is placed on the center line of each white key and the black line included in the front area of the movable display board (to be exact, the center line of the white key and the center line of the black line at the keyboard press area). ) is positioned so that Ki & display is located.

Therefore, the display board 16' is a concave K foot from the first key to the eighth key of the piano. ! Plank 16 is 9 from the left of the piano.
There is a range of 18K from the 16th key to the 16th key. The computer's storage device 14K inputs all the notes of one piece of music in two-way encoded form using this starting position t as a reference.

In addition, the display units 16-1 to 16-8K of the movable display board 16, which have all the notes of the melody part of one piece of music, are one pair tK.
The specified keys (in this example, S white keys and 3 black keys)
) Since it is impractical to be compatible with K, and some notes protrude from the indicated range of the K-roaring movable display board 16 during the performance of the song, the movable key board 16'l can be moved in either the left or right direction each time. It is essential to move κ! K becomes. A person skilled in the art should be able to easily encode a certain piece of music according to the κ fingering method so that the number of movements and the distance traveled are as small as possible. Movable display board
The range of movement for 6 may be as long as l keys, and the note
Bri! JK If the sharp K jumps to the high range as shown, K
II1, for example, K may span more than one octave,
Since the movable display board l6 moves a considerable distance to the right,
The performer must move his right arm accordingly. When this moving distance is defined as the number of keys, the maximum moving distance is 88-16=72, which is expressed by 7 binary bits. In order to indicate the left direction trlJ and the right direction by "0", 1 bit is added to this, and the left and right movement distance of the movable display board 16 is represented by a total of 8 bits. All the notes of the melody section encoded in this way are stored in the storage device 1.

The contents of the binary information stored in the storage device 14K are as shown in Figure 9. 1st block KFi 1st note of the melody part, 2nd block the 1st note of the accompaniment part, below, from $3 block onwards, the rattan 2nd note of the melody part, the 2nd note of the accompaniment part, the 3rd note of the melody part Musical notes are stored in the wish. -1 block first contains 3 bits indicating the number of fJAl notes in the melody section, 15 bits indicating the maximum of 5 notes, and 4 bits indicating the note length t, that is, 19 bits indicating 111 = 19 bits, and then If the 1 bit indicating the presence or absence of movement is Yes, and this pit is rlJ, that is, movement t-
If K is required, then 8 pits representing the amount and direction of movement t will be entered, and if it is "0", that is, if no movement is required, the second block will immediately follow.
The storage area of the storage device l4 can be used efficiently. The second block κ consists of 3 bits that indicate the number of first notes in the accompaniment section, 15k' ← that represents the maximum of 5 notes t, and 4 bits that represent the length of the notes, i.e., lS14 = 19 bits f:! l! Wasl9 bit, l♂t which indicates the presence or absence of K1 movement as in the case of the first note of the melody part, and only when this bit is rlJ, the amount and direction of movement?
:The 8♂t shown is included. Thereafter, all the notes of the melody section and accompaniment section are stored in the storage device 14K. Assuming that the movable display board IE16, 16' is moved to the leftmost corner of the piano, the 3 bits indicating the number of previous notes and the 19 bit K followed by the 1 bit and 8 bit indicate that the movable display board IE1608 pieces. Among the display bodies, the movable display plate l6 is moved so that, for example, the leftmost display body 16-1 faces, for example, the 40th 1 (in the lower example of FIG. 1, the note 29#i of C major is "C" and #' on the piano of 8JNl.
! This is the 40th key counting from the 1st key, including the black key). This moving device K will be explained fh Tol/cSa In Figure K, 300 and 301t'j are /Rrus motor drive circuits for the melody section and accompaniment section, respectively, that is, the moving device energizing circuit, and coils Wl to W4, W /1 to W/4 are the excitation windings of the arm motors M1 and M2, and are connected to the Murase circuits 300 and 30 via diodes and transistors with the polarities shown in the figure.

When the 1st note of the accompaniment part of the 2nd block, the 2nd note of the melody part of the 3rd block, the 2nd note of the accompaniment part of the 4th block, etc. are played one after another, the front notes @16, 16' are played in the same way one after another. It is moved in this way. When the note display body 16-1 of the movable display board 16 is moved to face the 40th key, the note display body 16-1 is displayed as a quarter note f, for example, as described in FIG. 5a. :I'm going to play sbo.

Part of the stator is attached to the pulse motor M11M20s.
If you use a so-called linear scale motor with a rotation speed of 8, the scale part can be used as it is in place of the guide rail, the guide rail is not necessary, and the resolution is higher than that of the conventional rotary type. This is an advantage.

Diagram 7a is a simple musical score example for playing the accompaniment part with the left hand.The arrow indicates when the sound jumps from the "r" note to the "冫" note, which is one octave higher, and the arrow points to the movable display board 16', so the actual score is shown. It shows the direction of arm movement. Figure 7b is a simple example for playing the melody part with the right hand, and shows the case where the "mi" κ jumps an octave higher than the "g" note, and the arrow indicates the movable display board 16, and therefore the actual arm. The direction of movement is indicated by the tube.

Note that the automatic keying device is also used by the performer K!
Shichido IIi K s Collection 3 a ~ 3 6 Figures and JIS
As explained in the axib diagram, the switch and detection circuit 90 shown in the dashed-dotted line in Figures 30 and 3F detect the detection, and the performance of the melody part by the performer and the accompaniment part are detected by successive blocks. Automatic performance begins.

In the case of the first embodiment, the automatic key press assembly K is also attached to the town movement display board l6, 16', and the switch circuit 13'
The automatic keying assembly may be activated or deactivated depending on the player's wishes by operating a suitable switch provided in the player.

Semi-automatic performance of the present invention! Device number one, #! To briefly explain the operation of the second embodiment, when the performer presses the start switch of the switch circuit 13', the control circuit 13 stores the memory bale 1114K and starts the first block (melody part).
When one of the t-protruding note display bodies 16-1 to l6-8, for example l6-1, is made to emit a K so as to pass a quarter note 1*, K1's protruding note display body 16-It, for example, when the key is pressed for that note. Move it to the position opposite the key you want. When the performance word presses down the key for 1 second (Fi), the switch state detection circuit 90K detects that the key has been pressed down or the pressed key has been released, and the performance circuit 13 then immediately switches to the second block (accompaniment section). Blocks of t continue to appear. This block is accompaniment part I!
key position tIt. This is a block containing coded information tubes for K.

In the case of the assembled embodiment, K is such that the movable plate 16' moves according to Vζ due to the continuous production of this block, and the note display body 16' moves to a position facing the key of the first note of the accompaniment section. −
The shape of the note is displayed on one of the keys 1 to 16'-8, and the performer presses the key accordingly. The detection circuit 90 is energized by this keystroke, and the third block (melody section) t-
The first movable plate l6 moves as necessary, and the note 1 becomes fjLWc so that the melody part @2 note 09K faces each other.
8! There is a note shape in any of the ho bodies 18-1 to 16-8! ! 6 In the case of the second embodiment, the player presses the key, and the performance is performed in the same manner.
For example, when a performance book hits a key corresponding to the @1 note of the melody section according to the ¥k button on the display, the keystroke is detected by the detection circuit 90K, the second block (accompaniment section) is read out, and the second block (accompaniment section) is read out. Accordingly, the second movable plate 16' moves, and the note display body 1g is in a position facing the key of the accompaniment part gleeful note.
The shape of the note is displayed on one of '-1-1σ-8, and the key is automatically pressed! lII#tt11 and automatic hit I! The key is automatically pressed by the device energizing device K. This hit #I
The detection circuit 90 is energized by K, reads out the third block of the melody section, and moves the first movable plate l6 as necessary, until it faces the key of the second note of the melody section flK Natsutomo note display body l6-1 The shape of the note is displayed in one of the fields 16-8, and the key is automatically pressed by the automatic keying device and the automatic keying device energizing device. An automatic accompaniment section will be performed.

The automatic keying time in the second embodiment is a whole note t, for example, -1 second, a half note Fi1/2 second, a quarter note 1d
In order to determine L/4 seconds..., we need a K4-bit tube converted to K, a pitch KFi of 3 bits, 3 bits to indicate the number of κ notes, 1 bit to indicate whether or not to move, and left and right keys. requires 8 bits for the amount of movement. Therefore, the maximum number of pits in this block is 3 x 5 + 4 + 3 + 1 + 8 = 3 1, assuming that a maximum of 5 keys are pressed at the same time.
The number of pits is the same as in the first embodiment.

If the movement detection bit is "0", the display board l6 is not moved. This is a case where the key corresponding to the note to be played is included in the display area K of the front board l6 at that time. Also, the key corresponding to the next note is the movable display board 16, 16'.
Of course, if the movable display boards 16 and 18' are outside the front box area (white keys and black keys separated by the movable display boards 16 and 16'κ), In some cases, it is possible to move the movable display boards 16, 16' depending on the fingering method, and this can be freely selected in programming, but the point is to move the movable display boards 16, 16' depending on the fingering method. In this example, the five white keys included in the display area of the Fi insert plate 16 are pressed by each of the five fingers from the left thumb to the little finger. do it.

If the number of notes in the accompaniment is only one note, the 3rd pit indicating the number of notes is indicated by binary "00", and in the case of 5 notes, it is indicated by binary rl 01 J; If there is no spring note, the FiZ advance is r000J, the note #i is not displayed, and no keystrokes are performed in the case of automatic keystrokes. Also, certain notes, for example, notes in the melody part, are displayed on the display bodies 16-1 to 16-1.
Even if 8, 16'-1 to 16'-8K are displayed, the performance of the song will remain stopped unless the performer presses the key corresponding to that K, and the corresponding accompaniment section will not start until the player hits the key. The note of the melody part that resonates with the note of is automatically pressed, and the next note of the melody part is pressed in the note board 111-
1~16-8K! lm and it is accompanied by display 叡16
, 16' is required! It will be moved according to N.

Alternatively, the detection device may be deactivated, the indicators may be operated one after another at a tempo determined by the programming K, and the movable attenuation plate may be moved as necessary. In this case, the performer is required to press the displayed keys one after another at a predetermined tempo, so considerable skill is required. However, even if the performer does not hit the keys in accordance with the keyboard, he or she can learn fingering and arm movements when playing the piano just by observing the positions of the indicators that are activated one after another and the movement of the movable display board. can.

In the above description of this specification, the melody part and the accompaniment part K
However, if the left-hand movable display board is not activated, only one movable display board is used for relatively simple pieces to be played with the right hand. Good too.

The features of the present invention are as follows. That is, when practicing playing a piano or other keyboard instrument, the user can move his or her arms in accordance with the movement of the movable display board, thereby allowing the user to learn fingering techniques and arm movements. Since the number of components such as the IiX2K1 detector, electromagnet, and nolenoid is reduced, manufacturing costs are reduced and the memory area of the storage device is significantly saved.

In addition, in stage lIIK where the performance manager was successful, the performance tFi
The left hand is the movable display board display K1 for the accompaniment part, and the right hand is the movable display board K1 for the melody section.

In the present invention, it is possible to display the shape of musical notes even if a liquid crystal, a fluorescent display tube, etc. is used instead of the light emitting diode F a % h.
Instead of representing the shape of a note from 6C, a single! ! Hot light D1
When the position of the next key to be pressed is displayed by ~D8K, the length of the note may be displayed in the form of the lighting time of the indicator light and represented by the color or brightness of the single indicator light t1. Furthermore, instead of a single indicator light, a 7-segment element may be used to digitally display, for example, a half note as r2J and a quarter note as "4". Also, musical notes are coded in advance and stored in a fixed storage device such as programmable lead-on 1 memory or Hakoa memory, and this is used as storage device 14,
During performance, it is also possible to display the display units 16-1 to 16-8κ one after another from the fixed storage device via the control circuit 13K. This storage device is used as a memory cassette to operate an electronic computer (control circuit).
3 and the main parts of the electronic computer such as the storage device 14) are installed at the cassette installation location of the computer.

In addition, since a display is also provided on the movable display board of the banharu part, the accompaniment part can be played under the fingerboard of the display, and the melody part can be automatically played by the automatic hitting #1 device. Also, if you press a key corresponding to the first note κ of one or both of the melody part and accompaniment part of one measure of a certain song, the control circuit will control the melody part and accompaniment part for that measure (or any number of notes). 13, and the first notes of the melody part and/or the accompaniment part of the next measure can be displayed at the same time as the performance ends. Furthermore, the K accompaniment section and melody section can be automatically played using an automatic keying device. In this case, the indicators on the left and right movable display boards will be lit one after another as the K is played, and the K accompaniment section and melody section can be played automatically. The display board itself can also be moved left and right as needed.
During automatic performance, you can learn how to move your left and right arms and learn fingering techniques.

This IJI1#-i mentioned above is a compact electronic computer called the K1. By simply memorizing the notes of the melody and accompaniment parts of one piece of music, even beginners can enjoy the town motion F! It has the advantage that one or both of the melody section and accompaniment section can be played freely by moving the board left and right and following the instructions on the display, and the fingering method can be learned naturally while playing.
