Definitions

  • the present invention belongs to the field of digital communications for the diffusion of signals to electronic musical devices.
  • MIDI Musical Instrument Digital Interface
  • 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.
  • 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.
  • the CME WIDI XU Wireless MIDI Interface plug-in 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.
  • 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.
  • US 2006/0005692 A1 describes a wireless system for musical interpretation.
  • 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.

  • 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.
  • 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 In this 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.

  • 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.
