Description

Wireless communication module for electronic musical devices

FIELD OF THE INVENTION

The present invention belongs to the field of digital communications for the diffusion of signals to electronic musical devices.

STATE OF THE TECHNIQUE

On a commercial level, there are several peripherals that allow you to transmit MIDI (Musical Instrument Digital Interface) messages to and from an electronic musical device wirelessly.

The MIDIJet is a low-latency wireless transmission system that works at 2.4 GHz and can reach an approximate range of 20 meters. It has an acceptable consumption (with alkaline batteries lasts about 30 hours), but it has two drawbacks: it can only work as a transmitter or receiver, not as both at the same time, and only supports up to 31 possible pairs of transmitters / receivers at the same time so that its application is discarded in orchestras with more musicians. In addition, the device is quite bulky, which can make it difficult to use with certain instruments.

There are other transmitters in 2.4 GHz, such as the M-Audio MidAir Wireless MIDI Interface and the CME WIDI-X8 Wireless MIDI System / USB Interface. The M-Audio MidAir Wireless MIDI Interface, is half-duplex and has a range close to 10 meters, which is quite small compared to the range that allows the CME WIDI-X8 Wireless MIDI System / USB Interface, which can reach 80 meters outdoors in situations with direct line of sight. This last system is powered by only two AA batteries and allows full-duplex communications using up to 64 MIDI channels. To connect to computers, there is the CME WIDI XU Wireless MIDI Interface plug-in, which acts as a USB-Wireless MIDI adapter. The main drawback of this set is its operation as a wireless replacement of a point-to-point MIDI connection, so there would be no possibility of collaborative tasks between several devices. In addition, it is not possible to extend the operating distance through a mesh network.

The M-Audio Mid Air 25 Midi Wireless 25 Key Keyboard is a small keyboard that functions as a MIDI controller and contains an embedded wireless transmitter. The keyboard allows to carry out the basic functions of MIDI editing, being the high consumption (6 AA batteries last an average of 2 hours) a great inconvenience in the use of this device.

Another commercial system to mention is the Midistream Wireless MIDI System. It is a UHF communications module specialized in transmissions from one instrument to another device, reaching a maximum distance of 80 meters outdoors and about 30 meters indoors. The transmitter is of relatively small size (the size of a pack of cigarettes) and is powered by a 9V battery. Again, since it is the wireless replacement of a point-to-point MIDI connection, there is no possibility of collaborative tasks between Multiple devices As communications do not occur through a mesh network, it is not possible to extend coverage through this mechanism.

The most relevant documents related to the present invention are the following:

-

US 2006/0230911 A1 describes a system for the remote control of a MIDI musical instrument through a wireless interface with audio support. To do this, use each of the stereo channels to send audio and MIDI simultaneously, so that a musical instrument can play that audio and, at the same time, react based on the arrival of these MIDI commands.

The main disadvantage of this application is that it assumes that the instrument has analog MIDI inputs, which is so rare that in practice its scope is very small. Instruments with conventional MIDI inputs would not be able to use the solution proposed by this application, unlike the proposed invention, which also allows manufacturers to integrate it natively into their instruments. Another disadvantage of US 2006/0230911 A1 is that it is not possible to control multiple instruments independently from a single remote station, which is interesting in certain cases. In addition, since there is no feedback from the instrument, collaborative tasks are prevented: for example, adjustments to the tempo. Finally, comment that when relying on non-standard techniques, there is a great dependence with the manufacturer regarding the distribution of works in this format.

US 2006/0005692 A1 describes a wireless system for musical interpretation. For this, it has an electronic musical instrument that acts as a substitute for the usual instruments (acoustic: string, watching, percussion) for those who do not have the necessary musical skills to perform music with them, or even for cases in which there is some kind of mental or physical deficiency. With an instrument of these characteristics, these people can join the musical discourse both individually and in groups. He

ES 2 379 425 Al

The system consists of two main parts: a wireless device that performs actuator functions and a central processor connected to the wireless network that executes actions as a result of the events generated by the actuator, which could involve the use of audio or even video .

Although the application allows the connection of several wireless devices to the central processor, the exchange of information between the different devices from one another is not contemplated, which restricts the performance of collaborative activities, unlike the proposed invention. As for the communication distance reached by wireless devices, there is a clear limitation, since at no time the use of repeaters to extend network coverage is claimed.

-

US 5,700,966 describes a system for managing sound effects wirelessly. The invention consists mainly of two parts: a bank of switches and a remote controller. The switch bank is, as the name implies, a set of switches that allows you to select at one time the application of one or more effects, from a series of options. The switch bank allows the musician to select effects comfortably, while playing music with his instrument. The selection made is communicated wirelessly to the remote controller, who modifies the control signals of an effects processor or an amplifier. This remote controller is also capable of generating a standard MIDI output. The most direct application of this invention is in the case of the electric guitar, where the application of effects (wahwah, flanger, echo, reverb, chorus, etc.) to the interpretation of the musician is very common. In that sense, the invention could be considered as a wireless replacement for a multi-effect pedalboard.

The main disadvantage of the invention is that the communication is unidirectional, from the bank of switches to the remote controller, which limits its application in collaborative activities. The invention is also limited to the one-one case, it being not possible to control multiple effects processors and amplifiers with a single instrument, or conversely, the control by multiple instruments of an effect processor and / or an amplifier. By not using repeaters to extend coverage, the request is limited in terms of communication distance.

-

US 2007/0079692 A1 describes a device capable of reproducing audio, and which has all the capabilities of the MIDI protocol in terms of storage, loading, playback, message generation, etc. It allows the configuration of the melodies used as an alarm in certain devices, such as headphones, headphones, etc. through existing mechanisms in the MIDI protocol, such as DLS (DownLoadable Sound Format), SP-MIDI (Scalable Polyphony), etc. It does not extend its applicability over any device capable of playing audio.

The main disadvantage is that the invention is about an individual device, without developing any network capacity. In that sense, there is no possibility of performing collaborative tasks. Finally, by not using intermediaries to extend coverage, there would be a clear limitation in terms of communication distance.

In general, it has been observed that there are no products or patents that describe wireless musical devices that allow the performance of collaborative and intelligent tasks.

Therefore, a communication module that solves the problems and limitations of what exists in the prior art is desirable.

DESCRIPTION OF THE INVENTION

The objective of the present invention is to provide a wireless communication module integrable in any type of electronic musical device that requires wireless MIDI connectivity, regardless of the device that requires it, be it a computer, a controller, a synthesizer, a sequencer, a system of lights on a stage, etc.

The communication module of the present invention comprises a controller, a wireless transceiver and an antenna.

The controller is a device that incorporates a processing unit, a memory and a communications interface. Internally it is capable of storing a program, which allows executing various types of algorithms that allow the invention to interact collaboratively and intelligently with other communication modules through the wireless transceiver. The controller incorporates a communications interface that allows interaction or electronic integration with other devices to provide them with new features that did not previously exist in it.

The wireless transceiver is a device specialized in the treatment of radio signals for communications, both for transmission and reception. The transceiver allows the controller to connect wirelessly to a network formed by communication modules, to carry out collaborative and intelligent activities related to the musical field.

ES 2 379 425 Al

The antenna is a device designed to emit or receive electromagnetic waves into free space, and is essential for the wireless transceiver to carry out its function. The transceiver can incorporate its own internal antenna, or use a connector for an external antenna. In this second case, the user has the option of selecting the antenna that offers the best coverage.

The wireless communication module for electronic musical devices includes:

•

a controller comprising processing means configured to establish communication with at least one external communication module and process, according to one of the previously stored algorithms, the information received from the modules with which it establishes communication, a memory configured to store a plurality of processing algorithms and the information received from the communication modules with which it establishes communication, and a communications interface configured to interact with said modules with which it establishes communication;

•

a wireless transceiver configured to transmit information to at least one external communication module and to receive information from at least one external communication module forming a wireless network composed of the modules that establish communication;

•

an antenna configured to emit electromagnetic waves into free space and to receive electromagnetic waves from free space.

The communication module may be comprised in a visual device, the controller being configured to display an electronic version of a score and to introduce modifications to said score. Additionally, the visual device in which the communication module is comprised can be configured to select at least one module with which to establish communication, whether between instruments of the same type, the director with a musician or the director with all the musicians.

The communication module may be comprised in a score editor with the controller configured to record scores and to make modifications to said scores.

In another case, the communication module could be limited to providing the collaborative and intelligent features, collaborative network layer, with the functions of registration and editing of scores in a secondary processor, application layer.

Preferably, the controller is configured to interpret music from a score, adapting its interpretation to the interpretation of the communication modules with which said interpretation is shown by a visual device that in turn comprises a communication module. In this way it would be the function of an accompanying virtual musician, multiple actors, with different roles, could interact in the collaborative and intelligent network. Each would provide different functionalities, and collaborate with each other to obtain more complex functionalities.

In this context, it is understood by interpreting, giving a personal meaning to a musical work, making it part of oneself, of what you feel inside. A musical work would admit multiple interpretations, playing with phrasing, structure, articulation, dynamics, etc. In the present invention, the interpretation is a set of parameters that the communication module uses to generate music (or produce musical information) and that are somehow calculated dynamically. This dynamism allows the treatment of music not to be monotonous but allows variations depending on the interpretive parameters selected naturally by human musicians.

Preferably, the controller is configured to display visual indications to the communication media with which it is in communication through the visual device which in turn comprises a communication module. In this way he would act as an accompanying virtual musician.

Preferably, the communication module comprises a sensory system which in turn comprises a plurality of sensors configured to detect the interpretation of the communication means with which it is in communication through the visual device which in turn comprises a communication module. In this way, a virtual teacher would detect the student's interpretation thanks to the sensory system, and provide visual indications to a musician using the visual device.

Preferably, the communication module is configured to perform musical improvisations from the harmonic and rhythmic patterns received from the communication media with which it is in communication. Thus, a cooperative virtual musician is available who has the ability to participate in a group of modern music, as if he were one more member, accompanying the rest of the musicians and performing improvisations based on harmonic and rhythmic patterns.

The communication module can be comprised in a scenario controller with the communication module configured to remotely activate the communication modules integrated in the elements that are part of a scenario. You could operate the elements from a centralized place, although you could also

ES 2 379 425 Al

integrate a portable actuator in the actors' locker room so that they are the ones that trigger the actions (for example, play an audio fragment).

Finally, the communication module can be comprised in a scenario configuration manager, the communication module being configured to establish the configuration of the communication modules integrated in the integral elements of the scenario with which it is in communication. The communication module of the invention would allow the formation of a wireless network, in which all the listed elements could collaborate to negotiate its configuration, or to establish its configuration as dictated by the scenario configuration manager. This would greatly facilitate the assembly and maintenance of a stage.

The advantage offered by the invention is the possibility of interconnecting electronic musical devices wirelessly, which gives musicians greater mobility on stage, by eliminating the existence of cables to carry out communications. Another advantage is the possibility of forming collaborative and intelligent networks, which allows the devices to be provided with functionalities for carrying out new activities that were not possible with the state of the art, as explained in the embodiment of the invention. . Finally, another aspect of the invention is the possibility of using intermediary nodes to extend the network coverage, and therefore, achieve communication with devices located at any distance.

DETAILED DESCRIPTION OF AN EMBODIMENT

Figure 1 shows the elements comprising the communication module 1. It is a module 1 consisting of three elements: a controller 2, a wireless transceiver 4 and an antenna 5. The communication interface 3 comprised of controller 2 is configured to interact with other modules 1 integrated in other electronic musical devices, with which it establishes communication.

Figure 2A shows a typical use case of the state of the art in this type of applications. From a MIDI keyboard 6, a musician controls a series of synthesizers 8, for example, three. For this, a wired network is deployed and uses an additional device 7 with separator functions that receives the output of the musician's MIDI keyboard 6 as input and distributes said input between the outputs, in this case, the three synthesizers 8 mentioned above. The additional device 7 distributes the received messages to each of the synthesizers 8 taking into account the channel of the MIDI message. The synthesizers 8 generate the output signal, using a speaker 9 to obtain audible sound. Therefore, the state of the art requires this additional device 7.

ES 2 379 425 Al

Figure 2B shows another typical use case of the state of the art in this type of applications. A series of MIDI keyboards 6, for example 3, control a single synthesizer 8. To do this, a wired network is deployed and uses an additional device 7 with hub functions that receives the outputs of MIDI keyboards 6 as inputs and concentrates them on a single output, in this case, the synthesizer 8 mentioned above. The additional device 7 obtains the messages received in each of the three inputs, and concentrates them in a single output, connected to the synthesizer 8. The synthesizer 8 generates the output signal, using a loudspeaker 9 to obtain audible sound. Again, the state of the art requires the additional device 7.

Figures 3A and 3B show the same scenario as Figures 2A and 2B but using the communication module 1. Both figures show the integration of the invention with the instruments, namely, a communication module 1 integrated in each MIDI keyboard 6 and in each synthesizer 8 found on stage. The synthesizers 8 generate the output signal, using a speaker 9 to obtain audible sound. With the present invention the same result would be obtained without the need for cables, giving the musician more freedom of movement on stage.

Figure 4 shows a case of use of the communication module 1 for the management of documentary information in scores for musical formations, specifically for the case of a symphony orchestra. To do this, each of the musicians (including the director) would have a visual device 10 on a music stand that would allow not only to display an electronic version of the score on the screen, but also allow the introduction of annotations related to the interpretation on site or mode of execution. Each visual device 10 would integrate a communication module 1 to interconnect in a wireless network and thus allow the exchange of documentary information in scores collaboratively and intelligently.

Next, and simply by way of illustration but not limitation, typical communication cases in this scenario that would be covered by the invention are discussed.

-

Group communications (multicast): Refers to the exchange of information between a limited number of participants. For example, violinists perform the same bow movements to give a sense of visual uniformity. The usual thing is that the first violin explains these movements on the score based on their personal criteria, marking the references of the bows that the remaining violinists must respect. In the proposed scenario, the first violinist would introduce the violin bows into his visual device 10, which would be communicated to the visual devices 10 of the other violinists automatically.

-

Individual communications (unicast): It refers to the exchange of direct information only between two participants. For example, it is customary for the director to give directions to a musician individually, for example the flutist. In the proposed scenario, the director would introduce the indication in his visual device 10, which would be communicated to the visual device 10 of the flute player.

-

Public communications (broadcast): Refers to the exchange of information to all participants. In the proposed scenario, the director could select a test compass on his visual device 10, so that the visual devices 10 would move the score to the measure indicated automatically.

Figure 5 shows schematically the use of wireless communication module 1 in case of score editing. Obtaining an electronic version of the score from an interpretation of the musicians, represents a much more agile method than the manual introduction by an arranger by keyboard and mouse. It is proposed, for example, the edition of a score belonging to the Baroque style, although the example described would be similar for other musical styles. For this, a typical baroque formation is available: Clave 13, Cello 12 and Traverso

14. These instruments would incorporate the communication module 1, which would allow them to network with the smart score editor 11, who would also integrate the communication module 1. The smart score editor 11 is a device that has the ability to register sheet music In addition, it is endowed with intelligence, which allows it to interact with Key 13, Cello 12 and Traverso 14 to carry out joint activities that would greatly facilitate the editing of the score. For example, the intelligent score editor 11 could mark a reference pulse for human musicians, or even detect errors in interpretation. Precisely, Baroque style music is based on a series of very clear compositional rules, resulting in the intelligent score editor 11 detecting possible inconsistencies in the interpretation: infrequent chords, incorrect resolution, prohibited intervals, etc.

Figure 6A schematically shows the use of wireless communication module 1 to create an accompanying virtual musician. An accompanying virtual musician 22 would behave as the technological replacement of a human accompanying musician, that is, from a score he is able to interpret music, adapting his interpretation to the interpretation of the accompanying musicians. Having a device with these characteristics is interesting to rehearse group works (orchestra, band, chamber groups, choir, etc ...) individually, or when a concert requires replacing a human musician.

ES 2 379 425 Al

An example scenario is shown in Figure 6A, in which an accompanying virtual musician 22, for example a pianist, accompanies a flute 20 to perform a flute and piano sonata. The flute 20 incorporates a sensory system 23, which allows the accompanying virtual musician 22 to adapt his interpretation of the sonata to the interpretation of the flute player 20 (eg adapting the rhythm). The sensory system 23 comprises the integration, preferably non-intrusive, of a plurality of sensors in any type of acoustic musical instrument so as to obtain information regarding the musician's interpretation in real time. This information can be used to activate events in a musical performance, from visual elements (lights), to sound (rhythm for percussion, performance of personalized melodies, etc.). With the sensory system 23, the acoustic musician is provided with the necessary technology to interact with the elements of the network: accompanying virtual musician, virtual teacher, intelligent score editor 11, etc. The sensory system 23 uses the communication module 1 through the communication interface 3 to connect with the remaining network elements. For its part, the accompanying virtual musician 22 can make his own interpretative decisions and show visual indications to the flute player 20 using the visual device 10. All this is possible thanks to the exchange of information in a collaborative network, so that each of the devices described incorporates communication module 1.

Figure 6B schematically shows the use of the wireless communication module 1 to create a virtual teacher 32. A virtual teacher 32 would behave as the technological replacement of a human teacher, that is, he would be able to give interpretive classes to a student 30 A device with these characteristics would be very interesting for self-taught learning. The virtual teacher 32 would detect the interpretation of the student 30 thanks to a sensory system 23, and provide visual indications to the flutist 30 using the visual device 10. All this is possible thanks to the exchange of information in a collaborative network, so that each of The described devices incorporate the communication module 1.

Figure 7 schematically shows the use of wireless communication module 1 to create music collaboratively. In some styles of modern music, such as Jazz, the performers do not follow the indications of a score (as was the case in case 6A), but the music is dynamically improvised based on a series of harmonic and rhythmic patterns (chords , bass, arpeggios, sequences, progressions, etc.). The idea is to have a cooperative virtual musician 40 who has the ability to participate in a group of modern music, as if he were one more member, accompanying the rest of the musicians and performing improvisations based on harmonic and rhythmic patterns. Figure 7 shows an example of a Jazz group, consisting of a saxophonist 42, a percussionist 43, a pianist 41 and a cooperative virtual musician 40 in the role of double bass player. Each instrument would incorporate a communication module 1, which would allow the formation of a collaborative network. The utilities of this cooperative virtual musician 40 are several: it could be used as a teaching tool in teaching, as a substitute for a human musician in case it is missing, or to experience new forms of musical expression.

Figure 8 schematically shows the use of wireless communication module 1 for intelligent scenario control. In the representation of stage shows, it is usual to deploy and synchronize a network with elements such as lighting machinery 51, smoke machinery 52, audio player 53, etc. The idea of this embodiment is to integrate the communication module 1 in each of the indicated elements, so that the communication network between said elements could be wireless and collaborative. The intelligent scenario controller 50 would allow the actuation of these elements from a centralized location, although the possibility of integrating a portable actuator 54 into the actors' locker room is also contemplated so that these are the ones that trigger the actions (for example, reproduce an audio fragment).

Figure 9 schematically shows the use of wireless communication module 1 for intelligent configuration management, in particular in the case of scenario control. The deployment of a network on a stage requires a previous step of configuring the elements: lighting machinery 51, smoke machinery 52, audio player 53, portable actuator 54, performed by the operators manually. The communication module 1 of the invention would allow the formation of a wireless network, in which all the listed elements could collaborate to negotiate its configuration, or to establish its configuration as dictated by a scenario configuration manager 60. This embodiment would facilitate enormously the assembly and maintenance of a stage.

Once the invention is clearly described, it is noted that the particular embodiments described above are subject to modifications in detail as long as they do not alter the fundamental principle and essence of the invention.
