Description

Rhythm generator

The invention relates to a rhythm generator for any pieces of music, which, depending on the number of notes or pauses, follows the rhythm of a written, heard or improvised piece of music through electrical output signals that Can be converted, for example, optically or acoustically, with one or more voices for soloists, Performing groups or orchestras allowed.

Rhythm and clock generators are used to set the tempo of a piece of music to be observed. Beginners in particular practice using this rhythm or clock generator To record fair values correctly.

In addition to the well-known metronomes, facilities with pen drums have already been established and perforated disks in the class 51el, which comprises a few patents, accordingly G 04b, patented, which, when turning, sets the rhythm depending on the position of the pins play a piece of music.

A number of electronic rhythm generators have recently appeared the periodically repeating basic rhythms of certain well-known entertainment music gates performances at different clock speeds and with special acoustic effects let represent.

The devices available up to now either do not go to the individual Rhythm of a piece of music, but only provide the basic measure or rhythm, on which the rhythm of the piece of music can still be counted, or are used as a rhythm generator Mechanically too complex for certain melodies and so cumbersome to handle, where they only reproduce short pieces of music unanimously that they do not prevail could.

The invention is based on the object by the consequence of Notes and rest values defined rhythm of a written or possibly just Heard or improvised pieces of music optically, acoustically or electrically Reproduce signals. Tempo variations as well as the traffic with external memories should be possible at will.

The solution to the task is a technique with the design options ahead of integrated circuit technology, but with related details with the current state of this technology is not received, as it is through technical Further developments may soon be out of date. It is crucial for the solution that the rhythmic processes of every piece of music - using a time system that the arbitrary temporal variations, such as increase, decrease, Multiplication, division and fluctuations of the empos are allowed to take place at the same time as the basis for the chronologically exact classification of the playback signals, the coded ones Memory commands or memory addressing is used. This Time system is based on the bar division, with the given or accepted music bar at least is divided as often as the smallest occurring note or rest value corresponds, the tempo changes by changing the duration of the act subdivision intervals can be performed and the display of the time values of notes and rests as Possibly coded memory information on the number allotted to the time values of clock division intervals is based.

The memory contains the time sequence of the in coded form Rhythm signs of all voices, the sign impulses, parallel or one after the other can be output, as well as coded, possibly using special memories Further information on the presentation of the special features of the piece of music, to save of storage space or to simplify the input and output process.

In addition to the coded form, the numbers of the bars or bar subdivisions can be used as well as the sequence of Xakt subdivisions with and without character impulses to form the Use storage information. The information is presented in all its specifics entered via an input unit, which is sent via encoder to the memory and possibly to special memories leads.

The beats and bars are derived from the bar subdivisions, whose numbers can be displayed and output, whereby the output unit uses that decodes the memory and special memory information and optically, acoustically or by means of electrical signals that are relevant to the individual voices distinguish and regulate their intensity, outputs. The sequence of operations in the electronic circuits can be compared to the clock division frequency high processing frequency, the control clock frequency. Through suitable adapter positions the communication with other rhythm givers or external memories should be enabled.

The time values of the notes and rests can be changed by pulse-like optical, acoustic or electrical signals, character impulses, at the beginning of their first Play bar division interval. To the time value of the pauses free of signals to hold, a pause can also be made by drawing impulses at the end of the last Measure interval of the previous note and on the beginning of the first of the following note.

Furthermore, the end of the last act subdivision interval can be the the last note of a voice.

In addition to the pulse-like display, optical or Output electrical duration characters from the beginning of the first to the end of the last Act subdivision interval of a time value for notes or rests range and the acoustic reproduction of which can be suppressed during breaks. The successive Time values can also be represented by changing signals.

The permanent characters can also be used at the beginning of a new note or rest briefly interrupted for marking.

The polyphonic recording and playback of a piece can be by dividing the memory into a corresponding number of consecutive Individual sections or individual blocks that have their own addressing, reach. Depending on the number of votes entered, the the individual voice missing memory space is calculated beforehand, the initial and end addresses of the votes stored in an address register of the votes, and the memory addressing as well as the write-in and read-out process via a Voice selection circuit can be made sequentially or in parallel.

With different storage space requirements per voice, the Enter start and end addresses also by hand in the address register of the votes, For the simultaneous reproduction of the individual voices in the case of sequential readout, the coded memory information first before the simultaneous further processing cached.

The storage of information of the individual votes can also without dividing the memory into contiguous individual blocks or individual sections serially for a specific section of a piece of music, for example a measure, take place. A certain number of storage locations can be used for each part and section offered which means that the individual voices are addressed via the addressing differentiated and can also be entered and read out individually. will the Information of the individual sections of the voices each have an identifier for identification Preceding the voices, the information can also be saved in a memory-saving manner connect to each other with different scope and via quick searches read out individually. Time values which in their duration exceed the limits of the section, should be specially marked if necessary.

Simultaneous processing can be carried out when reading out via an intermediate register or by reading out all the information from the voices of a section in parallel take place.

The time values of the notes and rests can be determined with information Width coded are stored, with identifiers for differentiating notes or pauses and other special characters can precede and follow an associated Identifier can be followed by several characters of the same type. The special characters allow the Simplified input and also the storage space-saving consideration of the special features of a piece of music This includes dotted notes, the corresponding introduction an identifier 1.5 times pause, leads, triplets, l'riller, fermata, repetition the sections, assignments and their advance notice marked by the repetition symbol, Xempov, Xakt- and clock division settings, etc.

For playback, the information including the identifier is decoded, taking into account the high control factor frequency for the decoded information Due to the short processing time, the display types provide a timely correct output which enables rhythm signals.

For this purpose, towards the end of the output of the decoded information, for example during the last bar division interval of the time value of the last note or pause the output of the next identifier with information word from the memory initiated with control clock frequency.

In addition to an identifier and the current value, the myriad of Store repetitions of equal time values of notes and rests encoded in the memory can be entered.

The identifiers in front of the representation of the number and time values of Notes and rests can contain all musical and device-specific special characters, which influence the rhythm of a piece, contained in their ode range and thus facilitate the input of the additional piece. Furthermore, the memory information Secure them with test marks and with the identification for the individual types of characters To save storage space, introduce a variable information grid.

Rarely occurring mostly long notes or pause values can be over an addition command is formed from the code stock after decomposition in an arithmetic unit be or by entering the time value breakdowns by hand via connected to the addition instruction. The output of the time values to be added is by controlling the position of the character impulse, e.g. at the beginning of the note and corresponding Display of permanent characters controlled.

The memory for the character impulses for identification can also be stored in the memory measure and / or measure division numbers belonging to the time values of notes and rests which are output in the event of coincidence with the corresponding counter readings. The storage of the full number of a certain width can be dispensed with, by only the last changing digits of the numbers after prior information may be saved with different widths. Distance numbers can also be used Enter the same in the case of prior information about the number of repetitions Time values, which can be used for all types of numbers, a saving of Allow storage spaces.

The note and rest values can also be stored in a memory according to the number of their clock division intervals corresponding to the time value occupy, whereby the character impulses according to the selected representation on the storage locations corresponding to the Xakt subdivision intervals by using one different from clock division intervals without a character pulse Storage information are set and for impulse playback or for display with permanent characters, in which the character pulse on the memory location at the beginning of a Note a short interruption to the marking the beginning causes be used. Also the last memory location of a voice, corresponding to the last one Measure interval of the last note, receives a character pulse. Identifiers and special characters can be used for memory words or memory types with a width of more than 1 bit with more than 2 types of status per memory location through single characters or character combinations also introduce.

Furthermore, as a further variant of the information types in a memory for the beginning of a note, the beginning of a rest, End of a time value if the time width and clock subdivision intervals are not fully occupied without character impulses, use characters approximately 2 or more bits wide with which display the time values of the notes and rests. Combinations of characters can also be combined to form identifiers and special characters.

For the processing of special characters, especially with an information width of 1 bit in the memory a special memory with the clock and / or clock subdivision number used for the time of processing.

Previously, identifiers and special character codes were used to represent special characters and special memory introduced. In some cases, however, the high control clock frequency storage space in the memory and special memory as a result be saved that by jumping backwards an existing listing or a Special characters can be changed in such a way that the following character is already taken into account will. With anticipatory input, the corresponding identifier or the special character can be entered without jumping backwards. Instead of jumping backwards, you can perform a forward search on the output containing the following character involved in the processing. With memory information about 1 bit wide, the position of the character impulses according to the selected representation by the reverse run to be changed.

While previous storage organization mainly information contained for progressive recovery, the aforementioned types of storage organization can also be used to display processes that are to be repeated cyclically. For this a cyclically addressable cycle memory is provided in which to be repeated continuously Information, such as the time values of rhythmic figures or the information about to accentuating beats can be entered.

This emphasis takes place via additional output signals of the mentioned Species. The time distribution is determined by the memory information of the relevant Measure or measure subdivision number at the beginning of which the emphasis must be placed, marked.

The cyclic addressing can be done via identifiers and special characters the memory or special memory can be controlled, with start and end addresses the processes to be repeated as well as the length of the repetition measures in the Cycle tape can be included.

The playback speed can be analog or digital in frequency adjustable control clock pulses over the number of allotted to them Jam clock pulses adjustable clock division intervals that are on the same Art lead to the adjustable beats and the adjustable measure numbers, are formed. By setting the control clock frequency, the tempo can be set at unchanged other setting values can thus be influenced.

For further variation, the tempo setting can be set individually for each voice to carry out rhythmic experiments.

Triplets only have 2/3 of the tempo that corresponds to their tempo designation Time value, which is indicated by an additional name or a special character in the memory or special memory and a special way of counting the control clock pulses will. Only every 3rd control pulse is used to set the tempo and related to the clock elements.

From the number of traffic jam clock pulses per clock subdivision interval, divisible by 3 the time value of the triplets becomes over 2/3 of that belonging to the specified time value Total number of control clock pulses formed.

Similar to triplets, the rhythmic features require such as Syncopation, lead, trills, fermatas, etc.

the output of continuous characters and character pulses, according to a procedure, which can also be used for simple current values. Via an identifier and possibly The factors of the clock division intervals also become special character information or the number of control clock pulses for the position of the character impulses or the sequence of permanent characters entered into the memory and control the associated Multiplication and counting elements in the output work. At Permeate they need that clock elements exceeding the specified time value in the counters of the collision the tempo and the clock elements are not counted to ensure a match in the way of counting the xuaik piece and the rhythm generator.

To increase the storage capacity, e.g. to increase the number the voices should be a rhythm generator by outputting the control clock and possibly clock subdivision pulses can synchronize other devices.

To fix the memory content of the rhythm generator, it is necessary to copy over to an external memory of a magnetic, optical or electronic type provided in the using the synchronization characters and the bar and bar division numbers of the beginning and the end of the item to be dubbed Section as well as the associated information of the special and cycle memories Transmission of the individual voices with the associated setting values for the clock elements is made. When playing back the information about the used Synchronization characters taken over into the various memories and registers, whereby to control the display and reproduction of the information, even if only partially or with a delay.

The communication with external memories takes place via adapter circuits to adapt the level and signal types. In particular, with magnetic storage several tracks for the individual voices or clock subdivision pulses u, ä, provided, or different frequencies are used for the individual voices or types of characters became.

Keeping the rhythm of something you heard or heard improvised piece of music allows an additional device that the determination the number of clock division intervals of the successive time values of Allows notes or rests, by placing between two character pulses, for display of the rhythm entered from tape or from playback devices or instruments derived, the clock subdivision intervals allotted to the time value in a Counting device are counted0 After determining the clock subdivision intervals per time value, this information can be fed to the coding that writes the Gin the information and the memory addressing according to the selected memory organization takes over. The time values of the notes and rests of the improvised or unknown pieces of music can be separated for each voice individually or with the appropriate Enter the cost of similar units for several voices in parallel. Above additional input signals can explain the special features when entering pauses and the like. be performed. You can save the necessary in the special and cycle Data for the special characters and, 7 repeat cycles as well as their beginning and End can be entered using the input keys in the input field. The dact elements are to be set manually and can be monitored by listening in. The edition can use all the options of the output system, including a delayed # or partial output, for example, of current values and special characters of the improvised or unknown piece of music can still be useful for checking.

The chosen tempo setting for an improvised or unknown Piece of music can be checked continuously.

The basis for this is the digital setting of the clock division frequency via the control clock frequency. The position of the entered character pulses in the clock division interval is made by comparing the jam clock pulses that have elapsed in the clock subdivision interval determined at the set ert. When 2 character pulses arrive per clock division interval an tolerance value at the end of the clock subdivision interval decides on the Allowed, while 3 character pulses per clock division interval are not allowed are. The cases that have occurred are shown by indicators that require a correction can initiate.

The advantages of the rhythm generator of the properties of the previously usual Also containing metronomes and clocks are varied. First of all, be the trailer the arduous and imprecise timing exercises that many have made it possible to break off prematurely of learning, decreased and by accurate, variable and always reproducible rhythm information replaced. By getting used to the exact Rhythms and the time values for notes and pauses become the natural rhythmic sensation trained and strengthened. This makes the learning exercises much more relaxed and Carried out relaxed, which is extraordinary for the development of the musical talent important is. The difficult polyphonic game alone on the appropriate ones Instruments like piano and organ, in groups or orchestras, becomes what the rhythmic As for accuracy, greatly relieved. Especially the rhythmic accuracy is one of the essential prerequisites for a successful interpretation.

For the advanced interpreter or conductor, Rhythmic studies with a previously difficult to achieve accuracy for all voices Perform across entire pieces. Generous storage and dispensing units with display and printing facilities can record the total time values. Especially for rhythmic ones The Rilytmus device is ideal for experiments in the field of modern music From this it follows that the entire practice in the musical field on an exact and easy to understand rhythmic basis is provided for the individual Interpretation will be very valuable when giving a lecture without a rhythm generator, as it is rhythmic Correctly practiced passages are later reproduced correctly even without a rhythm generator will can.

In addition, the time values of notes and pauses in musical Ideas and improvisations by simply beating the rhythm of the melody, or by impulses derived from the tones of the instruments or playback devices will determine. During the imprivization, the basic rhythm can be controlled by the rhythm generator still output with all variations.

The musical idea can thus be rhythmically stored by storing it Hold on to blows without interrupting the flow of thoughts by writing down must become. Especially for the beginner, listening to the basic beat results and the output of the time values for notes and rests is an essential help, since only The pitch still needs to be determined, e.g. by singing the melody on tape can be held.

The elements of the block diagrams can be used one or more of the large variety of modules for integrated circuit technology correspond or

a module can combine several elements of the block diagram.

First of all there is a control clock generator that can be adjusted in its frequency (1 - 15) intended for quick control of the processes, their various connections the individual elements have been omitted for the sake of clarity. the end for the same reason, the power supply and the detailed representation of the connections from a sequence control (1 - 32) for delete the formal operation, start, stop, fast or normal forward and rickety etc. to the individual elements of the block diagram.

The adjustable generator for the clock division frequency (1-16) is working on the measure division counter (1-17) and on the beat setting (1 - 21) via the one from the tempo input (1 - 3), the lower bar belonging to a beat ilunsint ervalle can be set.

The beats are counted in a beat counter (1 - 20), which in turn together with a setting signal from the tempo input (1 - 3), the the number of beats ro bar contains, via the bar setting (1 - 19) controls the cycle counter (1 - 18), which always starts a full cycle resets the beat counter to 1. The clock division pulses are the Memory logic circuits (1 -7, 10, 13) of the types of memory and the output and display elements (1 - 24, 25, 27) for setting the correct time output and display. Furthermore, the output and display clock system (1 - 25) with tasks via the As well as the status of the beat (1 - 20) and beat counters (1 - 18) provided. From the input field time values (1-1) and the input field special commands (1 - 2) are over the encoder time values, special parts (1 -4.5), which the data the tempo input (1 - 3) to convey the number of bar subdivisions per time value process with the memory information to the time value memory (1 - 8), the Special memory (1 - 11) and the cycle memory (1-14). In Fig. 1 is the Otherwise referred to as a memory part in a time-sert, special and cycle memory divided up. Because the general term memory always includes the time value memory must, the term time value memory is used in connection with the term memory no longer specifically listed. The terms special and cycle memory can, however to be used for more precise information together with the location memory.

The data of the tempo input (1 - 3) can also be transferred to the decoders time value memory, Special memory (1 - 23, 26) are supplied so that time values also independent of the set number of clock subdivision intervals per clock can be coded and stored. The data exchange with external devices or The time value memory (1 - 8), the special memory (1 - 11) and the cycle memory (1 - 14) via the elements, transferring external device (1 - 28) and playback of external device (1 - 30) controlled, the output of the rhythm signals of the individual voices through controllable acoustic, optical or electrical signals Type is according to the decoders (1 - 23, 26) of the memory information about the output Rhythm of the voices (1 - 24) completed.

The presentation of the rhythm of a piece of music is based on a sheet music example clarified over 2 clocks in Fig. 2a.

According to the smallest occurring notes and rests, 8 Clock subdivisions selected per clock (Fig. 2b).

The character pulses which characterize the rhythm are in Fig. 2c registered. The two consecutive pauses do not need a drawing impulse to get2 these are at the end of the bar subdivision interval of the curtain and at the beginning of the following note. This note counts as the last note of a voice and again receives a character pulse at the end of its last clock division interval.

Fig. 2d shows the way in which the rhythm is represented Permanent character, which are output for notes and rests, with the permanent characters at the beginning of the Notes are briefly interrupted to mark them, which is consecutive at the beginning Breaks can be omitted. Furthermore, the Suppress permanent characters in order to keep pauses free of signals (Fig. 2e). Leave it permanent signs of changing expressions, for example different frequencies, light signs output or similar in order to be able to distinguish the individual time values from one another (Fig 2 f).

For multi-part playback, the memory in ig 3 is divided into single blocks divided according to the number of voices desired. With a block by block Structure of the memory with one addressing device per block can be used for the Tuning by series and / or parallel connection of the individual blocks in the memory classify. Can the desired number of votes through the single block organization, In Fig. 3 there are 4 individual blocks, cannot be reached, so the individual blocks with several votes consecutively, with the address register of votes (3 - 5) stores the start and end addresses of the voices in the Eblzelblocks, as in Fig. 3 in the 4 individual blocks for a 3-voice reproduction is shown. In addition, by entering the start and end addresses of the Tuning by hand, if you have an extensive arithmetic unit, the address calculator (3 - 4). wants to avoid the storage capacity with different storage space requirements per voice take full advantage of the different allocation of storage spaces per voice.

The voice selection circuit (3 - 6) in connection with the address register the voices (3 - 5) and the address calculator (3 - 4) controls the memory addressing the individual blocks (3 - 11, 12, 13, 14) and the memory logic circuits (3-7, 8, 9, 1C). It uses the input information, number of votes (3 - 2), the possibly encoded memory information of the voices (3 - 1), the impulses of the control clock (1 - 15) and the clock division frequency generator (1 - 16).

In the event that a possibly very fine subdivision of the individual blocks (3 - 15, 16, 17, 18) for the individual voices addressed one after the other and thus must also be read out one after the other, is due to simultaneous output processing the necessity of a temporally coincident output a simultaneous register (3 - 19) provided that the read out memory information to the decoders and the Edition passes on.

If the memory consists of only one block, a polyphonic block can be used Storage of information by allocating storage spaces in individual sections per voice by shifting the addressing accordingly (Fig. 4). An address calculator (3 - 4) in connection with the voice selection circuit (3 - 6) determines the number of voices (3 - 2) that correspond to the input signal Storage locations per voice, by dividing the number of gess; mten locations by the number of the votes, their start and end addresses in the address register of the votes (3 - 5) can be saved. This register can be used to save the Address calculator (D - 4) also again by entering the Addresses (3 - 3) manually assign different memory locations reach per vote. The voice selection circuit (3 - 6) continues to do the Control of the memory addressing (4 - 2), the memory logic (4 - 1) and the sequential or parallel writing and reading process, including the input of the number of votes (3 - 2), the coded memory information of the voices (3 - 1) and the impulses of the control clock (1 - 15) and the clock division frequency generator (1 - 16) will.

A simultaneous register (3-19) again enables sisimultaneous processing the sequentially read out memory information of the voices.

Leave without dividing the memory into individual blocks or sections the information of the individual voices of the piece of music in sections, for example Enter bars, as shown in Fig. 5, with the individual voices in each case an equal number of storage locations of a certain information width of 1 or more Bit can occupy (Fig. 5a) or, differentiated by identifier, only the necessary also occupy different numbers of storage locations. Time values of notes or Breaks that exceed the limits of the selected section can be specially made for correct output. Addressing takes place again via a Voice selection circuit that also works when an equal number is occupied from Storage spaces per voice and section of the music stick through addressing jumps allows separate reading in and reading out of the voices. With sections of different length the separate readout is carried out by evaluating the identifiers in-house. For simultaneous further processing can be an intermediate register or the parallel reading of the information of all votes of a section can be used.

The organization of the memory is shown in the following in principle, being on details of the flow control from the input field via the encoder and addressing to the memories is not included, as these details are included in the individual storage types can be very different.

Fig. 6 shows a subdivided into individual blocks memory in which pro Individual block a different number of each from one entry and one or multiple information words composed of individual pieces of information for grades, Breaks and special characters are included. This via the input fields (1 - 1,2), Fig. 1 the tempo input (1 - 3) and the encoder (1 - 4,5) formed information are stored in the individual blocks and memory types belonging to the voices via the Addresses (1 - 6, 9, 12) entered. When reading out an identifier with an information word after the decoding <(1-23, 26) the information of the individual voices in the output, rhythm of the voices (1 - 24) or display field for Special information (1 - 27), with this type of memory organization according to the Information processing of a voice a signal to the addressing (1 - 6, 9, 12) is directed to read out and process the following with control clock frequency Information e.g. at the beginning of the clock subdivision interval provided for its output to reach. With a correspondingly high control clock frequency, the short information paths and the low clock division frequency allows this to be realized.

With the same composition of information from name and type of information the number of consecutive equal time values of notes can also be found tRdr record pauses in coded form. The number can be determined in the encoder by comparing and Counting similar time values can be determined or entered manually. After In the output unit, the number of repetitions is decoded using, for example, counters and Controlled comparator, with about the end of the last time value to be output in the last clock division interval reading out and outputting the next memory information can start again with the help of the control panel frequency.

In Fig. 7 the structure of a piece of information is shown, the can be processed with the elements of the rhythm generator described so far, those from the coded representation of the separation, the number of repetitions and of the current value. The width of the individual pieces of information, the information grid, directs according to the code used and the scope of the coding special characters and time values. The content of the identifier can be determined by the inclusion of coded special information is essential to simplify input and output and serve to save storage space. So can the musical special characters such as dotted notes, 1.5-fold rests, triplets, fermatas, trills, lead, etc. be coded in the identifier. Based on the individual identifiers, a Variable information grid for the individual types of characters to save storage space use. A test mark for the information can also be introduced.

While the smallest occurring note or pause values are taken into account by the degree of the bar division, large time values can exceed the scope of a coding restricted to the frequently occurring time values. An addition command is used to represent these time values (FIG. 8), which allows the subsequently entered time values to be added up to the identification of the next character without outputting a character pulse or an interruption or change of a permanent character between the individual time values to be added. Instead of an addition by hand via the input of the decomposed value, a Provide subtraction unit (9-4) which subtracts the largest from the coding stock from the entered time value until a negative value is obtained.

Then this is done with the next lower value from the Coding stock continued. Because of the division of the clock subdivision intervals down to the smallest occurring note value, the subtraction must work without a remainder.

The time values determined via the subtraction are individually or by determining their number in the number encoder (9 - 3), then specifying the number and time value (Fig. 8b) are stored. The number is determined by counting the frequency of subtracting a time value in the subtraction counter (9-5). When reading out, instead of addition, the output can be corrected by the addition control the output (9 - 7) in the sense of a suppression of character impulses or changes of the permanent characters take place between the individual time values.

Another possibility for fixing the time values is the Identification of their beginning by the associated number of the measure and / or the Bar division.

For this example, only the measure division number is used consecutively is also counted, selected.

According to Fig. 10, the signals from the input field (9-1) become inG Arithmetic unit (10 - 1) given that the number of clock subdivision intervals per Time value, according to the setting of the clock subdivision intervals per clock, determined and entered into the encoder (9 - 2), which also runs the arithmetic unit (10 - 1) also controls. Here too, the number of of the repetitions of the same time values, i.e. equidistant numbers, are also saved will. Before entering the memory billet the encoder (9 - 2) the total information for which several types are conceivable. After an identifier for the character type can be followed by the full measure division numbers, or shortened Numbers that contain only the last changing digits, with either a constant number width or, in the case of a variable number width, separations by characters or by instruction about the number widths in the identifier. Shortened Numbers can be chosen so large that consecutive time values always correspond clearly distinguish and the total number by addition and ascending Supplementation of the areas in front of it when jumping from a high to a low one shortened N. is formed by jner.

Furthermore, the number of repetitions of similar time values can be determined Combine and save the numbers by specifying all the mentioned types of representation, When outputting, after decoding (9 - 6), the time values and possibly theirs takes place Number and the further used special characters the addition (10 - 3) or the Formation of the total number (10 - 5) by shortened numbers and possibly their number displayed time values, which are then compared with the status of the clock division counter (1st - 17) are compared (10 - 4), whereby when storing the full numbers directly after the decoder (9-6) can be compared. If the comparator (10 - 4) Correspondence is established, the output of the signals is based on the output rhythm of the votes (1 - 24) carried out.

Since until the determination of the equality of the clock division numbers in the comparator the signals with the same Time delay processed the rhythm will still be correct in time, albeit through a high control clock frequency delayed, reproduced. In addition to the coded representation of the special characters, possibly with identifiers, the time values for notes and pauses can also be changed if necessary.

with identifiers through a storage space allocation according to the number of the clock division intervals per time value. For example, eighth note triplets come as the smallest time value, with 24 clock subdivision intervals per Measure eighth notes through 3 and an eighth note triplet through 2 bar subdivision intervals respectively Represent memory locations. The associated character impulses are approximately through "L" into the corresponding memory locations belonging to the clock division intervals and can also control the display by permanent characters while Clock subpart: igsintervalle without character pulses received about "O".

11 shows a possible memory organization, with a word-by-word representation. In this example, an identifier is followed by a special character, which is followed by a Identifier for notes followed by several time values, the last of which before the identifier a pause a character pulse also on the last clock division interval receives. After the identifier for pauses, a pause is displayed by the Number of clock division intervals.

If only 1-bit information is used (Fig. 12), this is not applicable Representation of the identifiers and special characters in the same memory and the memory is only assigned according to the required clock subdivision intervals, whereby the position of the character pulses is represented approximately by "L". Via the encoder (9 - 2) becomes out the time information from the input field (9 T 1) and the set bar subdivisions per bar with the signals for notes or rests the memory information is created and the memory addressing (4-2) is controlled. the Decoding of the time values is particularly simple and could, for example using a shift register or directly using the memories information take place.

While the use of 1 bit wide information has the disadvantage that special characters and identifiers are stored with only 2 types of characters per memory location can not be displayed in the same memory, this is when using two or more bit-wide words are possible again, as shown in FIG. 13 for 2-bit widths will. Specific meanings are assigned to specific bit combinations.

In this example: LL means the beginning of a grade including 1 Dact subdivision interval LO Beginning of a pause including 1 clock subdivision interval 00 2 clock subdivision intervals of a time value without character pulse OL 1 clock subdivision interval1 (at the end of a time value).

There will be pauses that also consist of several characters in the music clip composed are only reproduced as 1 pause, the character LO must not be used several times in a row occurrence. The same applies to the symbol OL.

By *; repeating these characters also combined with their characters, identifiers and special characters can thus be built up via the coding, of which an example is shown arbitrarily. For clear information processing must therefore always at least 1 character more than required for processing from the Memory can be read out. With the wide range of storage organization options Individual types of organization can store time values and special characters together awaken, such as 3. with 2-bit information, or prevent it, e.g. with 1 bit wide information. Then, as shown in Fig. 1, a special memory becomes (1 -11) to represent special characters, as they are in connection with the corresponding Memory organization were enumerated, used the special characters per voice with the cycle and / or cycle subdivision number of the processing time or of the relevant section of the piece of music. To ensure, that all special information belonging to a cycle or cycle subdivision is taken into account these can be saved according to the corresponding number and including of the following number for their timely consideration.

In addition to identifiers and special characters in the memory or in the Special storage can reverse values be used for the subsequent transformation of the memory information, if no predictive input is provided, and forward runs to determine the type of the next character for the selected technique. this offers itself through the use of a high control clock frequency. For jumping backwards or run is activated when a corresponding signal is entered, for example pause or last Note of a voice, the memory switched to readout and addressed backwards, until the first identifier to be changed or one to be changed in the decoder (9 - 6) Special characters appear. By sending a signal to the encoder (9-2) and switching a new identifier or a new one is issued by the encoder (9-2) on registered mail Special characters written in and back to the cached address of the starting point addressed back. When the output is forwarded, it is read out from the memory to the next identifier or special character of interest and this Information used during decoding. With the clock division addressed The position of the character pulses is saved, for example with 1-bit wide memory information by jumping backwards according to the desired type of display by rewriting changes.

The cycle memory (1 - 14) for processes to be repeated can be used for Recording of several repetition cycles in one of the types of organization such as the time value memory (1-8) or the special memory (1-11) and in the same technology be built up. The cyclic addressing is done via the control of the addressing cycle memory (1 - 12) via the sequence control (1 - 32).

When displaying the figures to be repeated with 1-bit information A register such as a shift register can also be used. The one from the time value memory (1-8) or special memory (1-11) read out control information are stored in the associated logic cycle memory (1 - 15) processed. As shown in Fig. 1, the same coders (1-4,5) and the decoders (1-23,26) as well as the input (1-1,2,3) and output elements (1-24,27) also used for the cycle memory (1-14) will. The control of the cycle memory (1-14) can when using the time value or special memory information can also be sent from the decoders (1-23, 26).

The tempo setting according to FIG. 1 is expanded in FIG. 14 by from the analog or digital adjustable control clock frequency via the setting of the control clock generator (14-1) the clock division, clock beat and clock frequency each via digital setting values from memory or input (14-4,9), via Counters (1-17, 18.20; 14-2) and comparators (14-3,8,12) are formed and displayed. This means that the control cycle and cycle subdivision pulses are always synchronous. The control cycle counter (14-2) is reset when the set value is reached, likewise like the clock division counter per clock stroke (14 - 6-) and the Beat counter (1 - 20). These setting options shown for the clock elements and the tempo allow via the display elements (14-5, 7, 10, 11, 14, 15) an always exactly reproducible Diversity that is still achieved through the use of setting values in the time value memory, Ground special memory or cycle memory expanded in the course of the l.iusik piece can. Another way of improving rhythmic experiments is to this arrangement for setting the tempo and beat elements for each voice To be provided individually or several times per rhythm transmitter.

The temporal position of triplets in relation to the individual notes is the same Fig. 15 shows the time value output. According to this, only 2/3 of the control clock pulses are used in a tride the time value of the individual note, their total number per act subdivision interval and its multiple must therefore be divisible by 3. A switching option under Application of the chosen technique is shown in Fig. 16. About a counter; 1-3 (16 - 1), the counts from 1 to 3 and is then reset, a pulse counter (16-2) is used for Adjustment of the clock division controlled. This gives the total number of control clock pulses always divisible by 3. The one to set the clock division frequency through the Number of control clock pulses selected 4th from (14-4) is in a multiplication unit (16- 8) with 2, and the number of the triplet designation on the current value, e.g. eighth triplet, omitted clock subdivisions multiplied by the number of To get control clock pulses per triplet. The product of the multiplication unit came to be used for the formation of the storage information or the Zeitrichtioxe Output something but a control clock counter triplets (16-5) and comparator triplets (16-6) allow to perform, the control clock counter triplets after determining each Triplet is reset.

The position of the character impulses or the beginning or change of the permanent characters with syncopation, lead, trills, fermatas, etc., which are caused by the memory information is specified via Kennun, Cen and / or special characters, can also be used for the output after the decoder (9-6) by a multiplication element (17-1) for the out of the memory information decoded multiples or fractions of the clock division intervals or control clock pulse numbers, a character counter (17 - 3) for clock division and / or control clock pulses and a character comparator (17-2) are determined (Fig 17). The signals for generating the output signals then go from the latter the end.

With trills etc. are character impulses at fixed intervals and the specified number of times. In the case of Permeate, those above the specified Time value exceeding clock elements including the control clock pulses for the Setting of the tempo and the clock elements are no longer counted, which is caused by stop the counter diaser circuit is reached, while in the output unit (9 -8) the counter continue working to determine the total value to be output. The arrangement is taking advantage of the high control clock frequency in their individual elements so to be repeated as often as the number of voices to be reproduced requires.

The output of the synchronization pulses for external devices is over External synchronization (1 - 22) shown, with both control clock and clock subdivision pulses be used.

Copying to an external memory, for example to fix the The contents of the memory are transferred to an external device (1 - 28) Fig. 1, which the Adjusts the signal level, and the sync code (1 - 29) to generate of synonym symbols for the identification of the individual storage types Information. When playing back via an external device (1 - 30) In addition to signal adaptation, the synchronization characters in the synchronization character decoding (1 - 31) are decoded and the information is sent to the associated memories. Can dubbing can be done at such a speed that no information overflows or deficiency arises in the output unit, a e.g.

also subsequent A ß with all the design options of the output work <9-8) and the clock element setting for checking purposes. this could when playing back from magnetic data carriers or external storage expansion will be realized.

The display elements should also be used for control purposes.

As a special case of external storage, storage expansions, e.g. pre-programmed read-only memories, read only memories, for example (ROM), in question, in which the information of a piece of music is already contained, which are then used by the decoders for playback via an external device (1 - 30) Time value memory and special memory (1 - 23, 26) and from there the output rhythm the voices (1 - 24), the output and display clock system (1-25) and the display field Special information (1 - 27) is forwarded, with the possibility of entering the tempo (1 - 3) or any stored tempo information can be used.

When dealing with magnetic data storage media, it is possible to use the and replay units of the data carriers by multi-track and / or multi-frequency systems can be used to the full.

The rhythm generator shown in its basic structure can be expanded to accommodate an improvised or unknown piece of music; The key point of this extension, implemented for this example with integrated electronic components, is a pulse shaper (18 - 1) Fig. 18s for the character pulses, which are entered manually or derived from playback units or instruments, for the time values that determine the rhythm, as well as an improvisation counter (18 - 2) that can be reset by resetting after each arrival of a character pulse, the number of clock division intervals per time value is determined by counting the clock division pulses, which are also fed to the clock division counter (1-17). The number of clock subdivision intervals per time interval determined in this way is fed into the encoder (9 - 2) in the otherwise usual information from the input field (9 - 1) where it is transformed according to the selected memory organization for input into the memory (4-3) and the addressing (4 - 2) is also taken over. For this purpose, the display of the time values and special characters (18-3), which is switched so that it can also be used for the information read out from the memory (4-3), is used.

For the subsequent display of the over the pulse shaper (18 - 1) and The time values determined by the improvisation number vr (18-2) are used by the encoder (9 - 2) and possibly the time value via the decoder (9 -6) of the display and special characters (18 - 3). Because of the high control clock frequency a Fast processing of the transactions is ensured, the described can Possibilities of the rhythm generator by the in Fig. 18 for the sake of clarity Facilities not shown, such as the special and cycle memory at the Determination of improvised or unknown pieces of music can still be used. The clock to be set by hand and all display devices can also be output use for input and output.

To accommodate an improvised or unknown Piece of music is the setting of the clock division and the subsequent clock elements that can be controlled via a display at the same time, is of crucial importance. Another control option is the determination of the pulse time in the clock subdivision interval (Figs. 19 and 20). A pulse position counter is used for this after the pulse shaper (18 - 1) (19-1), the control clock pulses that have occurred since the beginning of a clock division interval pays and is reset at the beginning of the next clock division interval.

bsr him the length of the 1st hit character impulse through the number of control clock pulses accumulated up to its arrival in the clock subdivision interval determined and displayed via register 1st impulse (19 - 4) and display 1st impulse (19 - 10) and can thus with the set value of the control clock pulses per clock division interval be compared. 2 character pulses per clock division interval from the pulse shaper may be permissible if, for example, within the tolerance value of 10; before the end of the clock division interval the 2nd pulse for the next clock division interval is counted. The momentum is calculated using a tolerance value calculator (19 - 3), the 0.9 x set value of A pulse position comparator calculates the control clock pulse per clock division interval (19 - 2) and the pulse position counter (19-1) are determined. If the 2nd pulse is within the tolerance range (Fig. 19 b), or outside (Fig. 19 c) what the pulse position comparator (19 - 2) above the date of the pulse position counter (19 - 1) when the 2nd character pulse arrives determined by the signals larger or smaller, this is done via the corresponding Register (19 - 5,6) forwarded to the display elements (19 - 11, 12). The registers (19 - 4, 5,6,7) to accommodate the display content for the display elements (19 - 10, 11, 12, 13), and these themselves are counted via a pulse counter (19 - 8), which displays the number counts the pulses per clock subdivision interval, and a selection logic (19 - 9) selected. The individual cases can be displayed by symbols or by means of control clocks and pulse levels for the arrival of the character impulses. Instead of the 4 registers shown here and 4 displays can also be used less by multiple utilization.
