摘要： An electronic percussion instrument, electronic musical instrument, information processing device, and information processing method are provided. The electronic musical instrument includes a control device that performs processing in which an envelope indicating a change in a reference value over time for determining whether vibration of the second playing operation element is self-induced vibration or excited vibration entailed by vibration of the first playing operation element is generated based on a waveform indicating vibration of the first playing operation element, and processing in which information on the basis of excited vibration of the second playing operation element is prevented from being included in information indicating operation of the second playing operation element using the reference value indicated by the envelope.

摘要： A reference part determiner determines a reference part from a plurality of parts including at least three parts. A subject part group determiner determines a subject part group from the plurality of parts, excluding the reference part determined by the reference part determiner out of the plurality of parts as a subject part group. An acquirer acquires a change pattern of a first audio parameter value set for the reference part. A changer changes a second audio parameter value set for the subject part group determined by the subject part group determiner according to a change pattern acquired by the acquirer.

摘要： A media-content augmentation system includes a database with a multiplicity of media files and associated metadata. Each media file is mapped to at least one contextual theme defined by beginning and end timings. A processing system couples to the database; and an input couples to the processing system. The input is in the form of temporally-varying events data. The processing system resolves the input into one or more categorized contextual themes, correlates the themes with metadata associated with selected media files relevant to the themes, and then splices or fades together selected media files to reflect the events as the input varies with time, thus generating as an output, a media product in which transitions between media are aligned with the temporally-varying events. The database may contain sections of digital media files. A method aligns sections in digital media files with temporally-varying events data to compose a media product.

摘要： Aspects of this disclosure relate to a switching circuit with enhanced linearity. The switching circuit can include a switch and an envelope generator. The switch can receive an input signal, provide an output signal, and receive an envelope signal corresponding to an envelope of the input signal. The envelope generator can generate the envelope signal so as to cause intermodulation distortion in the output signal to be reduced to cause linearity of the switch to be improved.

摘要： Rendition style parameters for realizing various release rendition styles and/or attack rendition styles are stored in a memory. Operation-related time lengths are detected which pertain to turning-on and/or turning-off operation of a pedal operator. Any one of the release rendition style parameters is selected from the memory on the basis of the detected operation-related time length, and the release of a tone is controlled with a characteristic of the selected rendition style parameter. Alternatively, any one of the release or attack rendition style parameters is selected from the memory on the basis of a velocity of the turning-on and/or turning-off operation of the pedal operator detected operation-related time length, and the release or attack of a tone is controlled with a characteristic of the selected rendition style parameter.

摘要： An attack transient detector determines the moment of note onset; e.g. the time at which a guitar string is plucked; from a signal generated by a musical instrument. Detection of the attack transient causes the generation of a trigger signal which can be used to control processing of the musical instrument signal.

摘要： A tone signal generator includes a tone signal data generating device, a signal data generating device, and a sound effects imparting device, such as a digital signal processor. The sound effects are imparted to the tone signal data based on the signal data in such a way that the digital signal processor processes the tone signal data and the signal data by repeatedly multiplying and adding them. In the process, a signal data supplying device supplies the tone signal data to the signal data generating device so that the tone signal data is used in place of the signal data. The digital signal processor processes the first tone signal data generated by the tone signal generating device and the second tone signal device supplied by the signal data supplying device so that the sound effects are imparted to the first tone signal data based on the second tone signal data.
