Description

Fields of application of the invention: independent application, or to any game or learning system or to P 41 43 257.6, and to P 40 41 766.2.

This application is divided into 3 parts, whereby each part an independent package of independent Features, but also as an embodiment present application used in any variation can be.

Both drawings, patent features, and description are divided into parts I, II and III, with drawings and Claims relate to the assigned part.

The invention relates to a method and the use of a preferred arrangement for performing the method with the task using standardized inexpensive cassette recorders such. B. Walkmanab play equipment, a multitasked reproduction of To reach recordings. Below that is the direct one Synchronization switchover option from tape given sound recordings understood in such a way that they Switching points result in a corresponding connection, such as B. Switching from slow playback Vocals, melody, or linguistic text on fast Playback, translated playback of foreign language texts, etc.

Definitions: In the explanations below defines the following definitions:

• a) tape or sound carrier in the foreground that tape recorder (e.g. Walkman), its sound carrier is currently playing,
• b) tapes or sound carriers running in the background  all other synchronous tapes, whose recordings are not currently reproduced are in sync with the band running in the foreground follow to always be in the foreground to be, with the foreground then running tape is running in the background.

In addition to the possibility of switching from one for all playback sources common sound carrier (tape cassette, etc.) by multiplexed recording of the sound carrier to be made using compression processes leagues (e.g. multiplexing of frequency moderately increased Signal parts, or filtering), can be found in the present Registration cassette recorders can be used at which such a compressed recording is unnecessary, whereby Cassette recorders, whose frequency ranges just for the Sound reproduction are sufficiently dimensioned, can be used can, using several such tape recorders.

In a development of the invention is to carry out the preferred method preferred a device which allows the use of tape recorders that not as remote control (= by electronic signals operable) capable players are designed, that is meet today's standard for cheapest devices. At such devices cause the playback head to move and the corresponding switching of the belt speed and the direction of the belt by hand against Switches operated by spring force. Preferred device permits the synchronous operation of such cassettes recorder to each other, which is multitasking guaranteed.

All of the tapes, which are each played back by a cassette recorder in synchronism with the other tapes, preferably have address codes which indicate the tape length being played. Furthermore, the reproduced addresses (A1, A2, An) of each tape are fed to a control circuit (cf. uP... Microcontroller in FIG. 1) which regulates the tape movement of the cassette recorders with one another for each tape drive (see m1, m2, m3), e.g. B. by low-pass filtered output of the control voltage (via voltage / current converter U / I) each corresponding duty cycle to motors M1. . . Mn (M3) if e.g. B. 3 cassette recorders are connected to the multitasking network for the purpose of alternating playback of music, singing, speech text in a slow or fast manner, as well as the optional playback of the translation for learning foreign languages.

Option in ( Fig. 1): The address signals of the individual bands, which z. B. are tapped from the second track of the tapes, are preferably filtered when decoupled according to their respective bandwidth used to dampen the crosstalk of the first track, whereby the address signals can be recorded even at the lowest possible level. Likewise, the first track through a steep low pass the upper frequency range in which the address signals z. B. are housed, cut off. Furthermore, the filter frequencies are an option, which filters the address signals, preferably filters (F), by means of the respective changeover signals (addressing ADF1... ADFn) corresponding to the frequency range of the address signals that results from the current band speed.

This procedure ensures that a each recorded sound carrier, the other sound carriers, or other tape recorders, in sync with the analog Switching possibility of the sound carrier play along with what for example by regulating the running speed of the Tapes according to the addresses synchronously and at addresses encoding the tape length (e.g. by gradually incrementing the addresses Tape expiry times, each of the same grade or Syllable picture).  

In detail, the procedure is e.g. B. designed so that First of all, a rule of conformity from Address marks of the tapes to be reproduced synchronously is determined and checked, e.g. B. Check for equality (corresponds to tapes run synchronously), or check for larger smaller (relevant pairs of bands to which the examination is assigned, run ahead of each other or lagging, which is compensated for by the band regulation).

In preferred further training this comparison testing, however, an offset value is provided, which one respective response time when switching the Sound carrier playback for swapping one in the foreground running sound carrier to one running in the background corresponds. In such a way that when the changeover point is recognized le what z. B. not only by switching directly from Hand, but also exclusively by an electronic Signal can be made electronically after it is done he switching the playback to another sound carrier (Another synchronous tape of another Cassette recorders) this sound carrier seamlessly on the spot which begins when repeating one of the band reproduced lesson led to the relevant fault location Has. This is e.g. B. the case when going to a musical train System according to P 40 41 766.2 or P 41 43 257.6 is recognized, that the musician can no longer follow the game. Or if recognized for a learning system according to P 41 43 257.6 is that the electronic switch to a second or Third text, which is switching the playback to one of the comes along in the background with the preserved audio, should take place.

This offset is then before the comparison of the Addresses added in accordance with the sign so that the in Foreground tape cassette running in the background is accordingly leading, whereby this The offset value is of course also in the address coding can contain the tapes with which the Comparison circuit is loaded, or a fixed one  Is worth. Because this offset value when comparing is taken into account, it is achieved that always in Foreground band running in the background running tapes is accordingly leading, independent which band is currently running in the foreground.

A further training in this is that while a tape for the slower playback of a practice piece expires another volume, which has the same practice pieces runs back around that piece and backtracking and These two tapes start playing when they are reached of the playback end of a piece is about that Alternate the same exercise piece, so that when the End of an exercise piece the previously rewound tape for the playback is switched and the playback of the Piece starts again at the rewound tape, so that an endless repetition of a practice piece until it is canceled through a detection function (no more errors or Key operation) is enabled. For this variant is then a fully electronic remote control function (electronic preferred operation) the cassette recorder is preferred, or formed externally, as in the further part of the description as further option described.

Fig. 2 to Fig. 4 illustrate a simplified variant without a remote control function for standard cassette recorders (Walkman), wherein in the event of a repetition of a piece of music a menu-guided key operation also supports the repetition. The variant described below enables standard walkway devices from the production of large quantities to be used for the preferred application.

As a special feature of this device, they are already existing controls of the Walkman device for the Operation for synchronous switching of several Walkman devices used immediately, so that no additional Electromotive drive required for this operation is.  

In a preferred embodiment, a plurality of Walkman devices can in principle be operated synchronously in the manner described, for. B. 2 or three devices (or several), where in the figures two devices are shown (Fig 2 and Fig. 3.):

A stand, which, for. B. as a scaffold or Box (box) is designed, looks for each whitemange advises a parking space, preferably in parallel Set up side by side so that from above accessible control buttons for the same functions lie along a line. Any along this line Row of function keys placed side by side ten Walkman devices is in each case indicated by a relevant function keys lying and in actuation direction of the function keys slidable rod formed, via the function keys with the same function all Walkman devices can be pressed simultaneously.

As shown in FIG. 4 for a further embodiment variant, these rods are arranged under the operating window (FE) of a hinged lid of a box in which the walkman devices are set next to one another from above in the manner described, wherein they are each pressed down by the operating window and can operate the Walkman buttons:

Rod ST1. . . presses all stop buttons STOP = BED1 of the Walkman devices,
ST2 rod. . . presses all rewind buttons REW = BED2 of the Walkman devices,
ST3 rod. . . presses all fast forward buttons F.FWD = BED3 of the Walkman devices,
ST4 rod. . . presses all playback power buttons PLAY = BED4 on the Walkman devices.

The fact that by means of a rod each full-length advised, for example, in the search mode or playback mode are switched on, however, does not mean that this immediately with the same belt speed of all Walkman devices takes place because the belt speed is one each Walkman device separately by a signal line a control device (e.g. microcontroller) regulated is.

This is done for all tapes, if each are reproduced individually in the foreground (the playback is acoustically audible, or at least in one Sequence program, e.g. B. Note sequence program or Text spot highlighting program, the information content is used), the tapes each with the playback speed of the tape recorders used are.

In contrast, the tapes run synchronously with the address specification a band running in the foreground in the background, then the regulation of the belt speed is the background bands from the address comparison between the im The foreground band and the one in the background running tapes derived.

Because addresses that belong together or match of foreground band and background bands not necessarily according to the length of the tape, but according to analogy mung (notes of a picture, text passages, speech syllables, Translation texts, more detailed explanations in the school system general type), they are in the background running tapes run faster or slower, than the tape reproduced in the foreground. Since the electronic control range of the motor speed of the belts however, a multiple of the playback speed of a band until a band can come to a standstill extends, this can be done through the central control of all Bands, which the pairwise address comparison between the volume running in the foreground and in Background tapes performs this rule  make. It is irrelevant whether the addresses of the band running in the foreground at the same time for each band running in the background or sequentially successively to generate the in the background current bands each fed control signal he follows.

As an extended option of the invention, this is still preferred band running in the foreground after a quartz frequency regulate the z. B. from the internal timer clock of the microcontrol lers, through which the central control is formed, is derived.

For the address recognition is because of the Regulation on the belts running in the background resulting different playback speeds requires a speed-independent detection Lich, as already for registration P 41 43 257.6 is proposed and explained.

The serial coding of the addresses is preferably carried out follow again (P 41 43 257.6) by ratio coding the signal values, e.g. B. subsequent frequency values, where then only the extent of the RELATIVE change in the Frequency for the detection of whether it is a logical low or logic high level is used. In Another preferred option is this change coding like a Modulo 2 code rated so that the changes are always alternate between positive change and negative change, depending on whether a log.0 on log.1 or log.1 on log.0 Transition exists. Furthermore, there are code-free breaks len (start-stop principle), which are statically unchanged Licher level are encoded, d. H. unchanged frequency at the record, from which a correction value for Determination of the belt speed (control) and as Option to readjust the address decoding reference for the tolerance assessment of a level change can be done optionally provided.

The separation of the address signal from the audio NF signal  is done using an existing second one Sound track of the tapes, which otherwise as a stereo track is used, with additional filter measures, in each case outside the frequency range of use Frequencies are filtered around the audio tracks S / N ratio continues to increase as well as the level at the Recording optimized in relation to this filtering (e.g. relatively low amplitude for the Recording track of the address signal opposite the Useful signal on the further track with the corresponding Filtering the address signal for everyone outside the Address signal frequency transmission range Frequencies).

In a preferred embodiment variant is then for the frequency-coded address signal a filter (high pass or Bandpass) provided that only the frequency range of the Passes address signal preferentially. To differ belt speeds of those running in the background Tapes an optimally set filter frequency enable (with unchanging filter frequency) an identical address mark for several frequencies superimposed recorded, which are graded so that in desired control range at least one of each superimposed frequencies of the filter frequency each corresponds. Hiebei can it z. B. sufficient if between the speed control of the tapes in question is set that on the filter in question the address signals with only two different ones Frequencies to which the speed control corresponds to the Filter frequency is adjusted and occurs desired speed from the duty cycle times between the transition points, when one of the occurs at both frequencies at the filter output. It is evident that this control procedure as an alternative or Complement to the preferred ratio detection evaluated can be used.

Another alternative preferred variant is the Switching the filter frequency in accordance with the  Address comparison of each recognized belt speed the microcontroller used in the central control, then in conjunction with the frequency ratio the use of a single frequency key device for the identification of high / low characteristic states is sufficient. With described filter circuit for the Filtering the address signal of the second track Walkman device can crosstalk between the both channels are improved that the address signal even then on the channel in question, if possible small amplitude in the upper (or as an alternative also lower) transmission frequency range of the Walkman device can be recorded with the lowest possible amplitude.

Another option is for a possibly used one Playback audio signal of the one running in the foreground Sound carrier, playback track concerned in the decoupling to further attenuate one from the address track despite low amplitude still possibly crosstalk Address signal, a low-pass function, which the Frequency range of the address signal blocks, provided. This low pass is then stable, just like that Selection filter of the address channel for the one in the foreground running sound carrier, since the tape speed of the im Another preferred option is the running of the sound carrier is regulated quartz-stable. The switchable filters of the Address decoupling for each in the background running tapes then enable an option lower amplitude for the address track of a concerned Band, each background band optionally in the Foreground can be switched.

It is with the standard cassette recorders used usual that the tape heads of the cassette recorder fast forward and reverse are lifted off.

On the one hand, it would now be possible to fast forward to be made exclusively via increased motor current leagues, then pressing the forward button (F.FWD)  through a fixed rod (ST3 cannot be moved downwards) is prevented, and instead on the pole or as another Operating key an electronic key evaluation, which this fast forward when the PLAY (game) button is pressed triggers via the belt speed control, provided is.

Of course, both options are the one Possibility of operating the forward run button and one additional key (TZ) possible.

If the forward run (with F.FWD) or the reverse run (with REW.) Is switched on, then the regulation of the tape speed via the modified motor connection of the Walkman is possible, but because of the lifted head the reproduction of the addresses, which are the synchronous operation measuring should no longer take place. For this reason, an additional tape location coding is tapped by photo-optical sensor, for. B. reflection meter, which scans (RFM1... For Walkman 1 ) via the usual viewing window of the Walkman device, which scans the spoke axis of rotation (SPRK) with which the tape cassette is driven via plug connection, with a reflection meter being available for each Walkman. The reflection meter emits a pulse for each passing spoke. These pulses are then counted from the respective last address status that occurred in the game mode (PLAY) and is temporarily stored in the control device (uP) and evaluated in such a way that this addressing also contains the number of spoke impulses from the spoke wheel of the cassette tape have to occur until reaching a predefined position. This predefined location can e.g. B. relate to points to which the belt is automatically stopped (by the motor current control) and the actuation of the PLAY key (play key) is required (for new calibration with longer searches), or the end or the beginning of a practice piece has been reached. Furthermore, the address marking, how many spoke wheel impulses are counted until the tape stops, depends on the direction, whether the tape is decoded forwards or backwards. This decoding is carried out, for example, with mechanical limit switches, which bear against the upper detent of the actuating rods in question and are switched accordingly when a rod is pressed.

These limit switches are then z. B. directly under the cover plate (DK), which has the window for operating the rods (cf. ES in Fig. 4). See limit switch ES in Fig. 2 for key actuation F.FWD = BED3 and REW. = BED2. The detection of the key press PLAY, if necessary, can be done, for example, by address decoding itself (available / not available); the same as pressing the stop button then corresponds to the case when neither the F.FWD and REW limit switches. the PLAY button is still pressed.

Fig. 5 further illustrates the attachment of a reflection sensor RFM with receiving window AF and double adhesive tape attachment DBK made for each Walkman device in the box. The reflection meters are then connected to the microcontroller input of the central controller via a threshold switch.

Furthermore, there is still one for each operating rod (ST1 ... ST5) an LED display element (light emitting diode) provided for a menu guided operation is used.

So shines z. B. after reaching a stop in the front or Return the LED for the joint actuation of the Buttons PLAY, after which the Fine calibration through described address comparison and, as an option, the playback of the audio signal can be felt until a certain point is reached. Should the desired place in the return have not yet been reached, the button for the Rewind again with repeated afterwards automatic stop and LED display PLAY for the repeated prompt this play button  press, etc. The menu is indicated by the LEDs user-specific and can be varied as required if necessary depending on the limit switch positions.

The cable feed to the limit switches of the control rods and to the LEDs assigned to the rods takes place via ribbon cable FK ( Fig. 3) to the circuit board mounted on the bottom of the housing box with the microcontroller electronics.

The housing box also has on the side where the Walkman devices have their volume control (L) and their headphone jack (KB1 ... KBn) for each Walkman a downward longitudinal slot, the connection between Walkman and control electronics (EL) for example looped-through cable connection outside the box, cf. KB1 in FIG. 2 and FIG. 3, respectively, or is wired within the box. (See option KST.. Cable duct in the double-walled case bottom of the box with sockets to the outside).

The circuit of this wiring is shown in FIG. 1 with:

A1, A2, An. . . are the headphone jacks on the Walkman devices (audio connections) which are connected to a multiplexer (e.g. CMOS-FET switch) are supplied to the audio signals by addressing (address line STAD) the control direction (UP) switches to a line (ACOM), which in the appropriate facility, each through this multiplexer in the foreground tape (e.g. musical train with musical Captain, or syncing an image display by text) with their address evaluation and if necessary also an acoustic reproduction of an audio signal (Option, or just acoustic reproduction of the Audio signal) is fed. In accordance with this switchover then takes place in the control device the internal switchover of the optional offset value for the address comparison, so that in the background  running tapes to the one running in the foreground always run a bit after. This makes it possible to look for Switching over made the part slow again play back where the error was caused.

Another option is a repeat memory provided, the storage of which the audio signal (ACOM) concerns and into which the audio switched over ACOM signal or address signal (depending on whether audio signal required) is constantly registered. Or as an option too only the signal corresponding to the slower playback (e.g. A2 at the input of the multiplexer).

Then is the end of the playback of a piece by the Band reached (determined by addresses), then the automatic switchover to the repetition of the Playback made possible by the repeat memory as long as until by changing the function concerned Switching to direct playback from tape takes place. These Function switching can be done by pressing a button or by recognizing the reaction behavior when actuated to the highlighted picture passages or music passages or Playing positions of an instrument take place. See also following part of the description.

The addresses reproduced in the circuit according to FIG. 1 by the different band channels (separated by a second track of a band and / or by frequency filtering from the actual audio signal) are supplied to the control (microcontroller uP) immediately after level conversion or explained filtering. Furthermore, according to the respective switching of a sound carrier to the foreground (with STAD), the addresses corresponding to this sound carrier are also switched to the device corresponding to the use (training or game guide), which can be done via the microcontroller or by separate separation at the switching output of the multiplexer (ACOM ) can be done at the other facility. Furthermore, the microcontroller can also be part of the actual learning device (musical train, image synchronization, or just acoustic reproduction) or, as shown in FIG. 1, as a front-end device, in which the switched audio / address signal of the walkman devices is supplied as a single signal as if it were a single Walkman device. In this version, the interface then has the following signals to the learning device, e.g. B. a learning facility according to P 41 43 257.6 or P 40 41 766.2:
ACOM. . . Audio signal, which runs in the foreground;
Option: address signals, can already be included in ACOM or supplied by uP,
Option: a mode signal, which indicates the current mode depending on the game or learning process and affects the selection of which sound carriers should play in the foreground (e.g. slow, fast, translation or repetition, if repeat memory is available as an option).

Design variant of the BOX ( Fig. 2 and Fig. 3):

B. . . Floor on which the Walkman devices KL1, KL2. . . KLn are set up parallel to each other, accessible from above when the hinged lid DK is open (see Fig. 2 hinge SC, opened lid of the box shown in dashed lines).

So that the cassette holder cover (D1, D2... Dn) of the Walkman devices (K1... Kn) remain hinged, show the Footprint of the Walkman devices on the bottom of the box corresponding groove (V) or are increased accordingly placed on a bar. The Walkman devices are here with its narrow side set up so that the control can be reached from above, BED (1... n) for each Walkman device.

The Walkman devices are fixed once through the side wall  the box, which has the slot (SL) for receiving the Has volume control of the Walkman devices, the Volume controls do not have to be accessible from the outside, if the playback amplifier can be regulated accordingly and this slot can be covered from the outside.

Furthermore, by a block KB, which for each Walkman device is available or as a continuous Piece of board can be executed and possibly still has a thin rubber pad, with which he on the upper narrow long side of the Walkman devices on one of fittings free (e.g. front) corner of a Walkman device in each case presses. This block (KB) is on a rail guide made of sheet metal (S1, S2) attached using a longitudinal slot can be inserted from above on screws (SR), these retaining screws on a support wall (KL1, KL2), which is the vertical narrow side of the whale mange councils that have no sockets or fittings, each supported, attached and these screws through holes (SL) on the housing wall are accessible from the outside.

The Walkman devices are therefore fixed by bumping on relevant side wall of the box housing and accordingly departments made up of the footprint of the Walkman equipment corresponds as well as for the purpose of Setting up the Walkman devices in the box accordingly Pressure connection (e.g. from the top KB, or also from the side as alternative).

The connecting linkage, which connects the function keys of the walkman devices with the same function, is housed in a frame, which is preferably designed as a hinged lid of the box, the cassette compartments of the individual walkman devices being easily accessible from above after opening the lid, as shown in FIG. 3 ( DK is opened here, see Fig. 2). The rear wall, on which the hinge (SC) of the lid is mounted, has a chamfer on which the lid lies slightly inclined to the rear after opening (angle a).

In a preferred variant, the connecting linkage is designed as round rods or flat strips (rounded off on the narrow side of the actuation), each of which has longitudinal slots on the frame sides of the cover in the direction of actuation of the operating buttons of the walkman devices (see ST / BED1, 2, 3, 4 in Fig. 2) are mounted and can be moved along the slots. In a further preferred option, these rods (ST1... ST4) are covered (DK) with a cover which has a window (FE) at the actuation point. In the variant according to FIG. 4, a button is also attached to the rods, into which the associated LED is also directly inserted (connected via rods in a groove from below by wire connection) or an LED field is provided on the side (LED1... N in FIG. 3 on the SD label) with which the menu-controlled operation is carried out, the required actuation of the rods being indicated by the corresponding lighting of an LED.

Suitable as material to be used for rods and BOX especially plastic or wood (for child-friendly Execution).

Tape player or cassette player after Claim 1 characterized in that the synchronization of the Address marks made on tapes are independent of the tape speed are read, and that of the Tapes a selected tape with its data content is reproduced, with the other tapes after this Tape synchronized to designated address marks run and to tape reproduced with the data content have different belt speeds, such as this is the intended address markings corresponds. 3. tape player according to claim 1 or 2, for use on a learning or game system which synchronization to acoustic signals Picture elements or marked positions of a surface or an object (e.g. musical instrument) manufactures, characterized in that a switching device is provided which the information content of a Sound carrier for use selectively in the Foreground switches while the remaining ones Sound carriers in the background according to the coded addresses run along, but are not reproduced.   4. A tape player according to claims 1 to 3, characterized in that the synchronism of addresses identified as matching, or as belonging together of the individual sound carriers of the tape recorders is encoded as follows:

• a) Associated addresses of the sound carriers correspond in each case to the same places on a musical picture, the musical pictures being reproduced on different sound carriers with different playing speeds, and / or
• b) Associated addresses of the sound carriers each correspond to the same word parts of a word structure (syllables, text, song, etc.), the word parts being reproduced on different sound carriers with different playing speeds.

5. tape player according to claim 4, characterized net that for the regulation of the synchronicity of the Band synchronization after agreement, or merging addresses, an offset correction was made as well as this offset value depending on the band, which is selectively in the foreground for each use reproduced, the assessment of the togetherness speed (or correspondence) from to tape run synchronization sation used addresses so influenced that sound carriers reproduced in the foreground in time leading to its associated addresses in each case Background is the current sound carrier. 6. Tape player according to one of the preceding Claims, characterized in that the individual Tape recorders external control inputs to control the Have tape speed through which the synchronicity of synchronism according to address markings (tape positions markings) is controlled. 7. Tape player according to one of the preceding  Claims, characterized in that on viewing windows of the tape recorders (cassette tape recorders) by means of optoelectronic sensor the rotation of the spokes (Plug) axis of the tape cassette of everyone Tape recorder for the purpose of supporting the Regulation of the belt synchronism with the lifted Playback head is scanned. 8. tape player according to claim 7, characterized net that a current address marking of the Sound carriers (tapes) in the tape control is cached and that to be concerned Address marker a statement is derived which Number of spokes (Thru) axis emitted pulses to reach certain synchronism points after this synchronism score synchronously running sound carriers. 9. Tape player according to one of the preceding Claims, characterized in that by the coded addresses at certain synchronization points synchronously running sound carriers, a sound carrier with the Playback speed of the tape recorder in question it is reproduced (acoustic device) and / or by visual display) and the others Sound carriers a reproduction of their on sound carriers recorded addresses at a tape speed make, which is regulated according to the synchronization points where the address recognition is independent of the belt speed encoded on tape and during playback with variable belt speed, which the Corresponds to synchronization points, is read. 10. Tape player according to one of the preceding claims, characterized in that an adjusting device for the tape recorders, which are in particular designed as standard Walkman cassette players, is provided, which has the following features:

• a) a fixing device for setting up the walkman devices,
• b) a linkage with which individual control buttons of the Walkman devices can be operated simultaneously.

11. A tape player according to claim 10, characterized characterized in that to actuators, which constituted by the linkage, display means are provided, the menu-guided operation made possible by a control device (e.g. LEDs light up or flash). 12. A tape player according to claim 10 or 11, characterized characterized in that to actuators, which electrical signals are formed by the linkage are tapped, which are the operating states of a Show control device. 13. Tape player according to one of claims 10 to 12, characterized in that the adjusting device as Box is formed, which has a hinged lid has, which can be opened from above, whereby the Cassette compartments of each other in the box Walkman devices aligned in parallel are accessible and that in this hinged lid the linkage, over which is the joint operation of the operating switches of the Walkman devices takes place, is integrated and when opening the hinged lid is lifted off. 14. Tape player according to one of the preceding Claims characterized by a frequency filter scarf that favors the address signal tung. 15. Tape player according to one of the preceding Claims, characterized in that the filter scarf tion by the sequence control with which by Address comparison the tape speed of the  Tape recorders are regulated in their respective preferred frequency range tunable, or is switchable. 16. Tape player according to one of the preceding Claims, characterized in that the arrangement with device, or the method, to one Glockenspiel or other touch instrument (e.g. Timpani) is used, which is a relative Target evaluation of his attack on a grade process per gram (or rhythm sequence program) in terms of intensity and / or rhythmically and the result this target assessment (e.g. as a deviation of the demanded speech emphasis or game emphasis to one Accompanying music or only to that through the captain display displayed defaults), the switching concerned Ribbons from background to foreground (to respective playback) electronically controlled is made.
