"MUSIC DEVICE"

The invention relates to a record with, when the record is rotated, by moving it past a playback head Scannable soundtracks. The record is intended for a music device with several sound generators for different Sounds and with game keys, at least some of which are used to operate the sound generator for several different Tones are arranged.

Some instruments, like an accordion and various? Organs, asked battery keys, which the musician with the left hand by pressing τ · .B. by pressing sounds a chord on a key while the right hand plays the melody. Although a simple / cord accompaniment represents an enrichment of the melody, this type of accompaniment quickly becomes boring, even if the player

lets the chord sound rhythmically. An additional device that provides rhythmic drum accompaniment, such as Köstagnsttan für eine Rumba-Rythmua, provides a greater entertainment effect. The player can select a suitable rhythm or measure by pressing one of several switches, the player then playing the melody while the rhythm is repeated over and over, but in the long run a rhythmic drum accompaniment can also become uninteresting, especially if it is also used for longer pieces of music does not vary.

A musical instrument with an accompaniment section on which it would be relatively easy to play, for example through Pressing a single key with your left hand but providing accompaniment that sounds similar to yours good musician with the left hand or accompaniment played by several musicians in a band, could be that of one not yet so perfect musicians can enrich music that has not yet been played so perfectly. For a wide range of applications, such a However, the device should be relatively simple so that the manufacturing costs remain low.

ί The invention is based on the object of a record

to create, which allows a music device of the type in question by pressing the game buttons each to be able to trigger entire tone sequences.

In order to achieve this object, the arrangement is made according to the invention Taken so that each of the soundtracks are concentric to the center of the record and radially separated from other soundtracks and a continuous sequence of repetitive patterns for scanning by a playback head wherein all repeating patterns within a track are of the same shape and the beginnings

the pattern of each track around the arc of the circle Trace are distributed that at least some pattern starts adjacent tracks pass the tape head at the same time.

An advantageous development of the invention is characterized by additional tracks with a single, through a sound head scannable wave pattern of the same shape.

With a record of the embodiment according to the invention the possibility is created by means of a simply built and easy-to-play music equipment, pieces of music ■ - with an artistic and relatively complicated accompaniment

to play. One can use a record according to the invention record the most varied of simple tones, accompaniment patterns, introductions and endings, which then go through any playback heads arranged in their area are selectable.

The invention is described below with reference to drawings.

The organ 10 shown in Figure 1 contains a piano-like keyboard for the melody and an accompaniment section 14 on the sound sequences for accompanying a melody that can be generated, which are played on the melody keyboard will. All of these follow-ups are made electronically by means of a optical disk 16 is produced, which is inserted through a slot 18 which is normally closed by a cover is. As FIG. 2 shows, the plate rests rotatably on two concentric ring pads 20 and is driven by a motor 21 driven, which rotates the plate with one revolution per 2 seconds. A lamp 22 is illuminated through a slit part 24 and through the platter and the turntable there are a number of photocells 26. Each photocell, such as cell 26a, is with a Sehalter 28 connected, the currents generated by the cell to an amplifier connected to a loudspeaker 32 can feed. The switch 28 is closed when the player presses a key or key similar to a piano key Switching element 34 arises that about an axis 36 against the force a spring 38 can be rotated.

FIG. 3 is a simplified representation of the plate 16 which generates the sound sequences which can be played when the switch closing elements are actuated. A disk as shown in FIG. 3 having 57 concentric tracks, numbered T1 to T57, can be used. The 37 inner tracks, labeled T41 to T57, represent sound tracks that provide a substantially constant sound. Sin section of the track T41, the aarstellt the 440 Hz pitch A is shown in Figure 4 increases. The track T41 is formed by a phantom line, which is bounded by the opaque margins. The transparent line has 880 changes or oscillations in width on its track length of 360 ° when the disk rotates at 1 revolution per 2 seconds. In other words, "The track is an annular area more variable

The track can represent the sound of a violin, flute, or other musical instrument, it can even reproduce the characteristic tremolo of a mandolin; However, it "always remains an essentially constant tone. The rest of the 37 audio tracks are identical to the T41 audio track, except that they represent different pitches in semitone increments, as in a scale corresponding sound of the soundtrack.

The majority of the 20 accompaniment tracks T1 to T20 represent sound patterns which are suitable as accompaniment for a melody generated with the sound tracks. Five of the accompaniment tracks are special sound patterns, such as an introductory or closing bar for a melody in a certain key, or a rhythmic sexton, applause, applause or the like, for which no special key is used. The rest of the 15 fluting I tracks, which can be described as harmonic tracks, | represent a pattern of tones based on a particular j.

The accompanying section 14 shown can be labeled or have the key of C major as the "basic position", since many kelodies are constructed in such a way that they are predominantly with C major chords can be suitably accompanied. As in Figure 7 shows, each button 61, when pressed, can have a -nreinsanen conductor 63 with a point 65 on the control panel connect, creating a "specific photocell" to the speaker amplifier is connected.

Pigur 9 shows as notation the sound sequences shown on track T11 of the record from Pigur 4, which sound when the player presses the upper C-button of the accompaniment section, i.e. the third button in the row labeled ^{"MAJ. * 1. Like Pigur} 9 shows, the tone pattern can be relatively complicated and contain sounds of a guitar, organ and a bass instrument · In addition, a drum rhythm is provided. The tone pattern shown in Pigur 9 is based on the C major chord or the C major scale in 4/4 time.

The harmonic pattern from Pigur 9 in C major is suitable for certain musical passages, but also require simple ones Melodies generally change the accompanying key for different melody passages. Pigur 10 shows 3rd set of feces the sequence of sounds recorded on track T19. Be ss The same instruments are used so that corresponding notes in the different tracks have the same tonal quality. The instruments play in the same rhythm and with the same tempo (number of beats per minute) as with the one in Pigur 9 pattern shown so that the tones occur with the same rhythmic speed. However, every note lies two semitones higher, making this pattern a D major Underlying chord. The rest of the 15 harmonic

Have accompaniment tracks similar relationships, but dio a.uf minor chords and a few diminished chords "based sound patterns include some sounds that are offset from the corresponding major chord. Unlike one. Accordion and other organs harmonic tracks are not easy full chords, but they represent a complicated rhythm. The harmonic tracks also differ from certain devices used in connection with organs for special sound effects that use a drum rhythm , since the harmonic tracks generate tones of a defined pitch and on defined chords or Scales based, whereby patterns based on different chords can be selected for different passages of a piece of music. The harmonic accompaniment tracks 16 to T20 should have the same measure (number of beats per measure interval, about three in 3/4 time and four in 4/4 Tact); they should also be the same Have a number of beats or attacks with equal spaces within each beat interval (in order to be able to represent a special rhythm such as cha-cha or foxtrot); they should represent the same relative tone patterns and, if any, ornamentation or phrasing, as well as the same musical instruments, and have the same tempo (speed) for a given record speed.

It is known that pieces of music are generally in measure intervals which generally count three or four beats per measure. In many palls there is the end of a Husik passage at which the accompanying key changes, i.e. H. one Changing the one harmonic accompaniment pattern based on a first chord to one on a different chord . based pattern should occur at the end of a full clock interval. The new harmonious pattern should be used in these palls start at the beginning of a measure. If © s were indicated to change to another chord pattern in the middle of a bar,

roped the new accompaniment pattern to finish the beat. Therefor must all harmonic accompaniments in phase or in terms of the manslaughter must be synchronized to each other in one cycle · As Figure 4 shows, all are harmonic Eegleitungsspuren, z. B, tracks T11 and T19, recorded as that they begin along an imaginary Saaialline R on the plate ", whereby all harmonic accompaniments start at the same angular position on the plate. It should be seen that when all photocells or other Abspislko'pf e along a substantially radial line lie, all harmonic traces along the same imaginary. Radial line should start. When the photocells but are not arranged along a radial line, then the harmonic traces should not be along one Start radial line, but be attached so that they for the existing arrangement of the photocells are in phase with each other.

It should be noted that, in general, a dip in elang occurs towards the end of a measure, while the start of a measure begins with a stressed beat. So when the disk rotates in the direction of arrow 60 (Figure A) , the ends of tracks T11 and T19 lie on the right side of the imaginary line R and have a substantially constant width, while the beginning portions of the track, the left start from the imaginary line R and show strong vibrations across its width.

When playing a whole piece of music, an oCor with several introductory and closing bars is often desired. For this purpose, one of the tracks, the button of which is marked with "I" in the first or • SPECIAL "row, provides a barrel, which represents an introduction or introduction to a composition

71A444221.1Z72

Introduction can be used for a melody whose key is in C major, which means that the melody can be accompanied predominantly by suitable accompaniment - they are based on a C major chord · The introduction is based on a G seventh chord and only uses organ, bass and drum (no guitar). The introductory track must be synchronized with the 15 harmonic accompaniment tracks that are played throughout the rest of the melody j, so that a player who plays | presses the introductory button, release it at the end of the introductory measure] and immediately afterwards one of the harmonic loading! can press slide buttons, being sure that the harmonic accompaniment starts at the beginning of a bar · The _; The introductory measure begins, like the other tracks T11 and T19 from FIG. 4, at the same angular position defined by the imaginary line B. It should be mentioned that the special introduction shown in FIG starts · A small lamp that comes on at the beginning of each bar, or some other similar device activated by the disk, can be used to indicate to the player when to start playing.

In addition to an introductory bar, one or more closing bars are sometimes desirable. Another shown in Figure 6. "SPECIAL" switch labeled ^tt II ⁿ plays a track with a ι circuit clock · Sin example of a closing bars is shown in Figure 12, wherein these specially circuit contains only sustained notes and a drum roll. Figure 13 shows another reasoning that can be used. Of course, each lead-in lane should end essentially along the imaginary Badial line H of Figure 4, while each final lane should begin essentially at this line.

The accompanying section 14 shown in FIG. 6 contains 21 Buttons or sehalter, which the on special chords

However, the record only contains 15 tracks to play these 21 harmonic! accompaniments. Read out 15 tracks to use some of the harmonic accompaniment tracks for accompaniments based on more than one chord. that some tracks are used for patterns based on multiple chords "is shown in Pigur 8, which shows various circuit connections and the different numbered tracks that are recorded when a special button" is pressed. For example, Figure 5 shows that, when a button 62 labeled "Α" is pressed, track T18 on the disk is played (although the button is labeled "A""it is used for both an A major and an A seventh chord) · If, on the other hand, another button 64- labeled "B ¹³⁰ " (B reduced) is pressed, • the same track is played xto. This is made possible by choosing a sexton based on a Α dominant seventh chord "that does not contain the root (da3 a) of the A dominant seventh chord Tone b, so that this sound sequence can be used for patterns based on either the Α dominant seventh chord or the diminished seventh chord in B. (SLn A major chord contains a, cis and e; an A dominant seventh chord contains a, cis , e and g and a prevented chord C ^ in B contains b, eis, e tmd g. The ^{pattern played when you press the "A" or 11} B ⁰ "button is based on a chord that contains the notes eis e and g · )

The track T18, which sounds when the A major button and the "3 ° o" button are pressed, also contains tones of the diminished s ep takkor ds in G and the diminished s ep takkor ds in E. Therefore, they also play buttons numbered G ⁰ tmd E ^{0 die}

Track T18. The T18 track is played every time one of the four buttons is pressed, so that there is only one

Sufficient trace to make mustor from four different harmonious Playing chords. The .E major button plays in a similar way

for diminished chord in F and button 70 for diminished chord in D is pressed. The two remaining buttons 72 and for diminished chords, representing the diminished chord in C and the diminished chord in A, play track T2o away. So only 15 different tracks are needed to assign a chord pattern made up of 21 different buttons to play.

The special switches or buttons in the first row in Figure 6 can, in addition to the beginning and ending bars, also represent common effects, such as applause and drums, which do not

have identifiable pitches and therefore not on any. Chord ". JsdvP switch, stria switch 7 £, has three positions, namely OFF (OFx), ÜN (ON) and momentary AIT (MOM ON). When the switch is depressed, the associated record track sounds continuously until the switch is switched to a middle position or to "AITS". If you press the switch below, the corresponding track will only sound as long as the switch is pressed. If you want to play a special effect for only one measure, press the player the lower T _e il of the switch and holds it for a stroke length. the effect can be played as long as desired by the top portion of the switch is pressed and held in this position is.

The plate 16 can consist of a durehsüiti.iron plastic disk or Surface are produced which contains a photographic emulsion which is exposed from the original plate and photographiscl is being developed. Of course, other types of plates, for example cylinders or belts, can also be used. the However, the plate should be of the Eadlos type, so that all

Bring traces back in yourself. The traces that represent long Cöns, the tracks T21 to T57, for example, preferably have waveforms which form a smooth connection between them j end of the Ereisuähn and create dos beginning; so that at this

No noticeable noise is made. The harmonic tracks do not need such a smooth union, since the end of a measure is generally quieter, while the beginning generally provides the attack of a new note. However, as was mentioned aot.on, the harmonic tracks should be in phase with each other so that no delay or lead-in of the beats is audible. Such an interruption in the clock is generally not noticeable if it is less than 1/30 of a second.

In order to provide a good frequency response, the slit part 24 through which the light passes and which is shown in Pigur 5 consists of a thin sheet of transparent material with a photographic emulsion. The photographic emulsion of the entire slit portion is exposed except for the thin slit line 80 so that only a narrow beam of light about 2.5 x 10 "* ^ ca (1/100 of an inch) passes through the plate.

An organ can have many different, interchangeable plates, each with a more harmonious set Includes accompaniments with different patterns to create a foxtrot, waltz, jazz sound, or other effects. Each track on the disk can contain more than one harmonic pattern clock interval, but it should contain a whole Number of clocks, and the different tracks should be related to the arrangement of the photocells or other Playheads are in phase with each other. Obviously can the record can be played on various types of organs, including organs where the

While the foregoing specific embodiment of the invention has been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made
