Abstract: Techniques for automatically controlling the expressive behavior of a virtual musical instrument by analyzing an audio recording of a live musician are provided. In some embodiments, an audio recording may be analyzed at various points along the timeline of the recording to derive corresponding values of a parameter that is in some way representative of the musical expression of the live musician. Values of control parameters that control one or more aspects of the audio playback of a virtual instrument may then be generated based on the determined values of the expression parameter. Values of control parameters may be provided to a sample library to control how a digital score selects and/or plays back samples from the library, and/or values of the control parameters may be stored with the digital score for subsequent playback.

Abstract: The present application relates to an improved flat panel loudspeaker design. According to some aspects, the loudspeaker may include a flat panel, and a driving unit coupled to the flat panel configured to produce resonant behavior in the flat panel according to an electrical signal received by the driving unit. One or more pieces of reticulated foam may be mechanically coupled to the flat panel, and in some cases may cover the entire surface of the flat panel.

Abstract: An ultraviolet (UV) light disinfectant unit is sized for portability and handheld use. The handheld UV light disinfectant unit includes a shell defining an interior cavity. A UV light is provided on an exterior of the shell. A transparent lens cap is provided over the UV light and is removably mounted to the shell. At least one writing instrument such as a pen and/or stylus is integrated into the handheld UV light disinfectant unit. The writing instrument is extendable away from the shell and retractable into the interior cavity. A slider button may be provided to slide the writing instrument between the retracted position and the extended position. A combination of a UV light and a writing instrument in a handheld device provides a user with a multiuse tool to accomplish tasks such as writing on publicly accessible screens that may make multiple steps of disinfecting desirable.

Abstract: According to some aspects, an apparatus is provided for controlling the production of music, the apparatus comprising at least one processor, and at least one processor-readable storage medium comprising processor-executable instructions that, when executed, cause the at least one processor to receive data indicative of acceleration of a user device, detect that the acceleration of the user device has exceeded a predetermined threshold based at least in part on the received data, determine that no beat point has been triggered by the apparatus for at least a first period of time, and trigger a beat point in response to detecting that the acceleration of the user device has exceeded the predetermined threshold and determining that no beat point has been triggered for at least the first period of time.

Abstract: Embodiments of an electromechanical transducer are presented. The electromechanical transducer includes a plurality of magnets and a substrate having a patterned conductive coil of at least one turn. The plurality of magnets are arranged such that a continuous magnetic flux path passes through each of the plurality of magnets. The substrate is located within an airgap between a given magnet of the plurality of magnets and an adjacent magnet of the plurality of magnets. The continuous magnetic flux path passes through at least a portion of the patterned conductive coil due to the location of the substrate within the airgap.

Abstract: An electronic piano is provided in which activation of a keyboard (7) and foot pedals (8) causes sound to be generated and output via a pair of conventional cone loudspeakers (210–212) each comprising a tweeter (214), a woofer (216) and a base (218). Simultaneously with the activation of the conventional cone loudspeakers (210, 212), sound corresponding to the notes played by using the keyboard (7) is also generated and output via two distributed mode loudspeakers (220, 222) which are arranged to output sound through the inducement of resonant vibrations. The conventional cone loudspeakers (210–212) act as a series of discrete point sound sources. The distributed mode loudspeakers (220, 222) act as diffuse point sources generating sound across the entire surface area of the panels (220, 222). The air disturbance patterns propagated by the two different types of sound source result in sound more closely emulating the sound generated by a conventional high quality acoustic grand piano.

Abstract: A sound reproduction method and apparatus utilizes both distributed mode and pistonic loudspeakers which are simultaneously driven over frequency ranges which at least partially overlap, for enhancing the spaciousness of the sound produced. The disclosure includes monophonic, stereophonic and multi-channel sound reproduction systems and electronic musical instruments such as digital pianos.
