Description

The invention relates to a novel Training of a multifunctional developed based on a panpipe Musical instrument, which is independent of length and material of the tubes arranged in a radius to meet the needs of the user freely selectable Tone range can take, using integrated circuits internally and externally using microcomputers and a manually operated Element as well as a traditional handling also halftones as well Scales and string or string instruments can also be intoned are.

The instrument holds previously unthinkable, technical for panpipes possibilities ready who a new quality allow the style of play with easy learnability, so that too high-quality live or studio music productions are presented can.

Panpipes have a long tradition in the folk music of Southeastern Europe and were spread worldwide after the time of antiquity. Originally as Shepherd's flute, consisting usually of natural materials, such as cane or bamboo, It has longitudinal flutes of different lengths, which in the course of development and for better playability - along their centers - in put together in an arch are. It was inevitable that the pan flute was also "discovered", especially as a solo instrument in musical performances larger orchestra included to become.

To do this, however, more was needed Refinements in playing technique and execution of the basic form in itself unchanged Instrument.

So according to DE 196 24 089 C1 a further developed pan flute known, which consists of up to 22 tubes arranged side by side. The peculiarity here is that the tubes, which are traditionally of different lengths, are made from different materials, that is, from materials that differ in terms of density. This will improve the quality of the

Sound generation improved but it does not release the user from it, with a high level of manual dexterity Learn to master the instrument.

With the solution according to WO 00/72 303 A1 a voice-controlled electronic musical instrument proposed, the user having a Microphone using electronics of the device various instruments can "retrieve" for accompaniment. With nuances his voice it is possible Music arrangements with the participation of e.g. B. trumpet, clarinet, Flute, Manufacture piano, electric guitar etc.

The instrument essentially exists a microphone for voice recording, one of the several speakers, a receiving body for electronics, Batteries and controls for manual function assurance.

The device corresponds in the broadest sense the construction of a synthesizer and becomes the accompaniment of human Voice used.

The full sonority of the aforementioned instruments can only be used to a limited extent in this form, so that the impression electronic sound generation is not canceled.

The solution after DE 39 11 836 A1 offers an electronically supported harmonica in combination with a synthesizer, whereby information on the generation of the respective tone to be played is obtained via pressure measurements in the combs. Overall, the "sonority" of the instrument. be optimized in its defined size, but new effects that expand the musicality of this instrument are not achieved. As before, a high degree of skill is required to play the harmonica, which is inherently mechanically retained.

With the example described State of the art, details of musical performances can be varied Instruments with the means of special materials as well as that Improve the use of specific electronics. But it is not possible to have an instrument - here one Panpipe - like that to further develop that a virtuosity of the game is perfectly presented can be and thereby the technically well-known physical possibilities not only achieved, but also expanded qualitatively.

It is therefore the object of the invention one modified in shape and size pan flute to create with new and relatively easy handling, whereby by means internal and external integrated circuits one in real time conducted Evaluation and implementation of signals for the purpose of increasing the sound volume takes place and simultaneously intones string and string instruments can be.

According to the task according to the Features of claim 1 solved. The further design the invention results from the claims 2 to 9.

The following additional information about the teaching according to the invention is required:
The instrument, which corresponds in its basic form to a panpipe, does not necessarily have a fixed number of tubes arranged side by side, the length of which does not have to differ from one another. The number of tubes available depends on the individual playing needs of the user, so that a number of more than 27 is also possible. To control the instrument in manual terms, the pipes are arranged on a system in the radius in such a way that the contact points of their lateral surfaces on a receptacle form an imaginary joint Form a curve. The tubes are unlocked at the top and bottom.

In the side by side Pipes are in the first third of the "wind sensors" for registration of air currents, which houses the link between the user and one in the handle Represent evaluation electronics.

An analog filter bank receives the Signals from the wind sensors and ensures that while playing the instrument a defined frequency spectrum is reached. This will then in more usual Way to digital by means of an A / D converter (analog-digital converter) Signals converted, including a manually operated play lever Influences, the signals then housed in a microcomputer in the housing of the Panpipe - processed become. With the aforementioned lever, the usual range of sounds Pan flute, mainly by half tones, be expanded.

The first microcomputer, also called Identifiable multiplier of the input signals has several Processing stages, whereby after passing through such processing stages, like sample memory, envelope generators (one for each tube), grade manager the "raw data" of the grade manager ultimately achieved - before voted on uses the time controller to control the A / D converter - the midi data generator supplied , the latter converting the signals obtained into generated standard signals converts and over a midi transmitter interface to this in a timed sequence Generate tones provides the second external microcomputer in real time.

about receives the midi input the second microcomputer the data through the midi converter for the simulation as a central element - in two Way z. B. the instrument panpipe be adapted to nature. This means that a simulation of the "mouthpiece" (reaching a certain volume by means of a more or less strongly blown or blown air stream per tube) and the simulation of the air column itself can be carried out in real time, so a natural sonority dependent on of the "commitment" of the user.

Subordinate effect generators are used at z. B. to produce reverb effects.

about A D / A converter used on the output side becomes analog-stereo phones Signals provided through appropriate electro-acoustic systems can be made audible.

The invention will now be based on of an example are explained in more detail.

The housing 1 the pan flute carries up to 27 tubes of the same length, each with an existing wind sensor 2 , which made of any material - e.g. B. also made of glass - existing pipes with the wind sensors 2 are advantageously fixed in a curve with respect to the contact surface at a point on its outer circumference.

The pipes with wind sensors 2 downstream analog filter bank 4 ensures that a certain frequency spectrum of the recorded tubes is recorded, which the A / D converter 5 is fed. With the AD converter 5 the provided analog signals become digital for processing in the microcomputer 6 converted, this in the tonal range by means of the A / D converter 5 manual lever 3 finds a functional extension by generating half tones.

The microcomputer 6 contains several electronic components, whereby after the input signals have passed through the sample memory 15 , the envelope generators 16 , with the grade manager 17 the "raw data" generated by the latter via a time controller regime 19 on the one hand to tax A / D converter 14 and on the other hand the midi data generator 20 are fed. Via the midi transmitter interface 21 on the microcomputer 6 become the output signals 22 via the midi input 23 in the microcomputer 11 via data connection 9 transferred. The main component here is the midi converter 24 - for that by means of the mouthpiece simulation 25 and the tube / air column simulation 26 in "real time" the natural sonority of a "conventional" panpipe, depending on the intensive use of the pipes with the wind sensors 2 is achieved and in the sense of the development of the aforementioned instrument according to the invention, the intonation of intermediate tones can also take place. The effect generators 27 provide a nuance of the virtuoso playing, so that finally via existing outputs, an analog audio output 12 or / and a digital audio output 13 stereophonic sounds can be made audible.

For easier and more virtuoso playing, the upper openings of the tubes are with a wind sensor 2 only beveled on the player side.
