A button is disclosed, which includes a button unit suspended movably vertically in Z-direction in a fixed frame and having a button body with an upper actuating surface and at least one central shaft extending vertically downwardly from the button body and extending at an upper end below the button body horizontally into an extension. The shaft and the extension having a translucent material such that they commonly form a light guide which is fixedly connected to the button body. The button additionally includes a light source vertically below the shaft. Light from the light source leaves vertically upwardly and enters the shaft from below. The button further includes a first optical device arranged in the vertical upper area of the light guide above the shaft for deflecting light that has entered the shaft from the light source in a horizontal direction into a plane of the extension.

The present invention provides a tactile surface for partial timbre sound synthesis instrument, the tactile surface comprising a swiper and a selector pads. The swiper and selector pads comprise a top silicone layer coated with polyepoxide that extends down through casework to a printed circuit board with capacitive touch sensor pads.

Disclosed herein is an electrical connector for transferring electrical power and data through mating with another electrical connector. The electrical connector comprises an insulating connector housing presenting a mating interface, wherein the mating interface extends in a first plane. The electrical connector further comprises a contact arrangement comprising a plurality of electrical contacts extending at least partially normally to the first plane. The plurality of contacts comprises one or more first pair of electrical contacts arranged to transfer power. The plurality of contacts further comprises one or more second pair of electrical contacts arranged to transfer data, wherein each one or more second pair comprises a receiving contact and a transmitting contact. Each electrical contact in a pair is located symmetrically to the other electrical contact of the pair with regards to a second plane normal to the first plane.

Provided are a mobile device, a method for operating the same, and a non-transitory computer readable storage medium. The mobile device includes a touch display configured to sense a user input; a memory; and a processor configured to examine, upon receiving the user input for generating an audio file from the touch display, characteristics of the user input and characteristics of a first audio included in first audio data stored in the memory, generate melody data based on the characteristics of the user input and the characteristics of the first audio, generate a second audio based on the melody data and chord information included in the first audio data, and generate the audio file by combining the generated second audio with the first audio.

Advanced, but user-friendly composition and editing environments for musical scores may be provided using the types, and in some cases the instances, of computing devices that will in turn consume musical score content so generated. Indeed, by integrating musical composition facilities within synthetic musical instruments that can be widely deployed on hand-held or portable computing devices, a social music network that includes such synthetic musical instruments gains access to a large, and potentially prolific, population of authors, editors and reviewers, as well as to the community-sourced musical scores that they can generate. By curating such content and/or by applying crowd-sourcing or other computational techniques to maintain quality, a social music network may rapidly deploy the new and ever evolving content that its user community desires.

A single axis position transducer uses an elongate permanent three pole magnet having a radial magnetic field at a spot along the magnet in which the magnetic field has radial field lines that decay as 1/R. R is the distance from the center of the magnet along a radial field line perpendicular to the axis of the magnet. The spot has a first pole of one polarity, and the magnet has poles of the opposite polarity spaced along the magnet on opposite sides of the first pole of the radial magnetic field located at the spot. At least one magnetic field sensor is positioned proximal to the spot along the elongate member that detects the motion of the spot and electrically amplifies the sensor output.

Systems, methods, and devices for providing interactive striking objects (e.g., drumsticks) and performing actions in response to striking motions of the striking objects are disclosed. In some embodiments, the systems and methods provide an interactive drumstick, which includes a lighting display located at a tip portion of the interactive drumstick, a motion detector contained at least partially within the drumstick, a processor and memory contained at least partially within the drumstick, and an interactive system stored within the memory of the drumstick. The interactive system includes a striking motion module that determines striking motions of the drumstick with respect to a virtual percussion instrument based on accessing information measured by the motion detector, and a display module that causes the lighting display to present a certain type of illumination based on the striking motions determined by the striking motion module.

A virtual instrument for real-time musical generation includes a musical rule set unit for defining musical rules, a time constrained pitch generator for synchronizing generated music, an audio generator for generating audio signals, wherein the rule definitions describe real-time morphable music parameters, and said morphable music parameters are controllable directly by the real-time control signal. With this virtual instrument, the user can create new musical content in a simple and interactive way regardless of the level of musical training obtained before using the instrument.

A controller to control an electronic musical instrument includes: first to third input units for a user to input play data and a frame having the first to third input units arranged therein. The frame has a wall surrounding an internal space, the wall has a three dimensional surface, the first to third input units configure one set, and the first to third input units configuring one such set are arranged adjacent in a circumferential direction of the three dimensional surface and the plurality of sets are arranged adjacent in a longitudinal direction of the three dimensional surface.
