A musical instrument special effects device, comprising a special effects unit connected by wire between the musical instrument and an output device, where the unit is operatively arranged to selectively produce at least one of a plurality of preprogrammed special audio effects; and a controller is operatively arranged to wirelessly control the special effects unit.

A wireless headset configured to process music interface protocol (e.g., the Musical Instrument Digital Interface (MIDI) protocol) received wirelessly (e.g., via a Bluetooth™ connection or an Internet connection) by a source device is described herein. The wireless headset includes a first and second headset speaker and a wireless transceiver unit to receive a stream of data over a wireless connection. The wireless transceiver unit includes a sound processing logic unit that converts the stream of data to a stream of data associated with a music interface protocol outputs audio corresponding to the converted stream of data to the first and second headset speakers.

An input device for operating a musical instrument having musical behavior of string instruments, which comprises a key plate unit containing a set of input keys to be pressed by a player, in order to generate a first set of electric input signals, which emulate a combination of pressed keys of a musical instrument or a combination of pressed strings; a stick unit with variable tension of displacement including a stick to be moved by the player between predetermined discrete positions, which emulate a combination of strummed strings of a musical instrument.

A system including a method and device for real-time synchronization of MIDI generated sounds with audio program material originating from a Digital Audio Workstation (DAW). Provided is a real-time feed-forward control system for the generation of sound arising upon the execution of MIDI commands time-synchronized with the playback of audio program material. The system uses one or more audio synchronization tracks to accomplish synchronization. An audio interface device converts the data streams created by the playback of audio program tracks and audio synchronization tracks into electrical audio signals. The proposed MIDI interface device uses the audio synchronization signals output by the audio interface device to strobe or clock out MIDI events waiting on a FIFO buffer inside the device. Finally, the re-synchronized MIDI events are transmitted to the sound generating device in perfect synchronization with the audio program material.

An input device for operating a musical instrument having musical behavior of string instruments, which comprises a key plate unit containing a set of input keys to be pressed by a player, in order to generate a first set of electric input signals, which emulate a combination of pressed keys of a musical instrument or a combination of pressed strings; a stick unit with variable tension of displacement including a stick to be moved by the player between predetermined discrete positions, which emulate a combination of strummed strings of a musical instrument.

Provided is a transmitter for musical instrument and a mode switching method thereof. A transmitter for musical instrument which is mounted on an electric guitar determines the electric guitar is in a not-in-use state when a continuation time in which a square sum of accelerations output from a three-axis acceleration sensor is smaller than a power-saving threshold value is longer than a power-saving transition time, and the transmitter transitions from a normal mode to an energy-saving mode. On the other hand, when the accelerations in the energy-saving mode becomes equal to or greater than a release threshold value from a state of being smaller than the release threshold value or becomes equal to or smaller than the release threshold value from a state of being greater than the release threshold value, the electric guitar is returned from the energy-saving mode to the normal mode.

Various examples and techniques pertaining to audio output monitoring for failure detection of warning sound playback are described. In one aspect, audio data, which includes a plurality of bits of a first sound sample and one or more control bits for integrity check, is retrieved from a data storage. The audio data is processed by: (i) performing an integrity check on the first sound sample based on the one or more control bits, and (ii) playing back a first sound using the first sound sample. The first sound can be a warning sound in automobile applications.

A method of operating a UI for controlling a virtual musical instrument implemented can include receiving an input corresponding to a selection of a cell within a particular array of cells arranged in a sequential arrangement within a cell matrix, each array of the cell matrix assigned to MIDI notes associated with audio sample data stored in a computer-readable medium that, when triggered, causes the audio sample data to output corresponding audio, and each cell within its particular array of the cell matrix, in response to being selected for playback and upon being triggered to begin playback, causes the audio sample data corresponding to the cell's particular array to be played. The method further includes determining that the input's duration is above a threshold time and expanding a size of an array containing the selected cell and adjusting the adjustable parameter of the selected cell based on the input.

A sound generation device according to an embodiment of the present invention includes an identification unit configured to identify one mobile communication terminal from one or more mobile communication terminals capable of communicating, an acquisition unit acquiring setting data regarding generation of a sound or control of generation of a sound from identified one mobile communication terminal, and a sound generation unit configured to detect an operation on an operation unit and outputting a sound on the basis of detected operation and the setting data.

Predetermined musical data for a song is received. The predetermined musical data includes chords and lyrics and rhythmic structures of the song. Audio data of a band generating music of the song is received. Generating real-time vocal audio that is in rhythm with the audio data and in harmony with the chords. The vocal audio includes the lyrics and is of a predetermined voice.
