摘要： A method for generating a music file for recording user performance may include: detecting, by a sensor, an event indicating a status change of an execution device of the keyboard instrument; generating, by the sensor, a signal corresponding to the detected event; receiving, by a processor, the signal; and generating, by the processor, a music file based on the signal. In some embodiments, the execution device may include a weight lever. The weight lever may a concrete structure in the keyboard instrument to simulate a rebound force generated by hammer striking on string, by striking on an elastic structure. In some embodiments, a rebound force for a first weight lever may be different from a rebound force for a second weight lever by adjusting parameters of the elastic structure or the weight lever.

摘要： A method and apparatus for measuring and recording keyboard motion in which an array of magnets and sensors capture key movement (100-107) with high accuracy. This method uses a non-contact sensing and assembly technique that requires no mechanical or electrical connections with the entire keyboard assembly, thus making installation and servicing easier, as there are no cables or other devices required to connect or remove from the keyboard. This method also uses a mathematical algorithm to adjust for sensor distance variation (from the sensor to the key), allowing for high accuracy over the entire keyboard. Finally, this method allows for sideways keyboard movement (soft pedal in grand and some vertical pianos), without affecting the sensor readings.

摘要： A controller having proximity sensors associated with a trigger, such as beam sensors, configured to generate proximity data as a function of where each beam is broken along its span. A variety of control signals are be generated, whereby each beam can be configured to be spatially controlled and mapped to mimic other controllers, such as those of a DJ controller or other entertainment device. MIDI messages may be generated in response to positioning a member in a beam as detected by the proximity sensors. Each beam may be configured into a plurality of proximity zones, where a different MIDI message is generated when the member is positioned in the respective proximity zone.

摘要： The key actuation system is designed for use with a keyboard instrument of the type having multiple keys (10). Each of the keys (10) has an upper and lower surface and is pivotally supported above a key bed. A front end (12) of a key (10) may be depressed by a player to play a note. The key bed extends under and is spaced from the lower surface of the key. The actuation system includes an underlever (240) in the space between the lower surface of the key (80) and the key bed, and between the front end (268) of the key in the pivotal support (82). The underlever (240) has one end (242) that is supported in a stationary position relative to the key bed and another end (248) that is movable towards and away from the key bed. The movable end (248) of the underlever (240) is in mechanical communication with the key such that movement of the movable end of the underlever towards the key bed causes the key to move as if depressed by a player. An actuator (246) is in mechanical communication with the underlever and operable to move the second end of the underlever towards the key bed.

摘要： The keyboard for electronic musical instruments has an electromagnet (4) for each key (1), this electromagnet being excited by a control circuit (8), using pulsewidth-modulated signals. The armature (5) is mechanically coupled to the respective key (1). If the electromagnet is excited, the armature (5) pushes the key (1) in the direction of an upper limit position. The electromagnet also provides a sensor for detecting the position of the key. Either the course of the electric current through the electromagnet is evaluated in the presence of an active control signal or alternatively, the countervoltage induced in the coil of the electromagnet (4) is evaluated during the pulse pauses of the control signal. The control circuit (8) modifies the pulsewidth of the control signals according to the position that is detected, the key characteristic being adjustable in this manner.

摘要： A sensing system for a keyboard. Each key sensor comprises passive and active resonant circuits. The passive resonant circuit has a resonant frequency and the active resonant circuit excites the passive resonant circuit at the resonant frequency. At least the active resonant circuit, and optionally also the passive resonant circuit, comprises one or more coils with windings in opposite senses. A sensor driver drives the active resonant circuit with an RF drive signal at the resonant frequency, a multiplexing system multiplexes the drive signal such that simultaneously driven key sensors are separated by at least (k-1) keys, and a detector detects a level of RF signal from a driven key sensor for sensing a position and/or velocity of a key. The combination of coils with opposite sense windings and multiplexed sensor addressing facilitates the use of multiple sensors in close proximity.

摘要： A wearable sensor system is disclosed that provides a measurable magnetic field that changes horizontally within the range of motion of human limbs. The wearable sensor system includes a magnetic sensing device, and one or more magnet devices that provide the measurable magnetic field with a strength exceeding the Earth's magnetic field. To this end, the magnetic sensing system provides a "personal" magnetic field about a user, with that magnetic field traveling with the user and overpowering adjacent interfering fields. The wearable sensor system may include a sensor arrangement that measures a strength of the personal magnetic field and field direction to perform horizontal localization, and may send a representation of a same to a remote computing device to cause an action to occur. Some such actions include output of pre-recorded or synthesized musical notes, for example.

摘要： A device and related method for detecting, controlling, and recording keyboard motion in which individual magnets, sensors and actuators associated with each key capture and re-produce key motion with a high degree of accuracy. The method uses a non-contact sensing assembly technique that requires no mechanical or electrical connections with the keyboard assembly, thus making the device easy to service and install. The method also uses a mathematical algorithm to adjust actuator key movement at a very rapid rate making it possible to install in a variety of panios with different key weights and still be able to play with high accuracy. Finally, the device system dynamically maps the keyboard to which keys are in playback mode (124) and which are in record mode (125), allowing the use of both modes simultaneously, thus letting the player add to (layer) performances.
