Methods and apparatus to use predicted actions in VR environments are disclosed. An example method includes predicting a predicted time of a predicted virtual contact of a virtual reality controller with a virtual object, determining, based on at least one parameter of the predicted virtual contact, a characteristic of a virtual output the object would make in response to the virtual contact, and initiating producing the virtual output before the predicted time of the virtual contact of the controller with the virtual object.

Provided is an electronic percussion instrument that is capable of simulating a playing technique for an acoustic percussion instrument. A tubular body part is opened on an axial end surface, and a head is attached to the axial end surface to be struck on the front surface. A capacitance sensor includes an electrode that generates a capacitance with respect to a detected conductor, such as a human body, positioned on the front surface side of the head. Because the capacitance sensor detects a change of a capacitance corresponding to a distance between the electrode and the detected conductor, whether the detected conductor approaches (contacts) the head or presses the head can be determined. As a result, the playing technique for the acoustic percussion instrument is simulated.

Electronic musical instruments as disclosed, include sensors to digitize and alter the sound using FSR sensors in the mouthpieces and other elements of the instrument to mimic the variations available in analog instruments.

A key guide structure for a keyboard instrument, which is capable of stably and appropriately guiding a key pivotally moved by key depression without generating noise. The key guide structure has guide holders each erected below a guide recess of each key, and guide members mounted to tops of the guide holders, respectively, each for sliding contact with lateral inner side surfaces of the recess. Each guide member includes a body disposed between the lateral inner side surfaces of the recess with a predetermined clearance, two lateral flexible portions laterally flexible and extending from lateral ends of a front or rear surface of the body in a manner protruding in a front-rear direction, and two lateral contact portions which are provided at front ends of the flexible portions in a manner protruding sideward and are in contact with the lateral inner side surfaces of the recess.

A handheld musical instrument for playing a variety of audio program, the handheld musical instrument includes a main body portion with one or more sensors, a handle portion engaged with said main body portion, wherein said handle portion includes one or more control buttons to select a type of program to be played by said handheld musical instrument and a gesture detection module for detecting gestures associated with said handheld musical instrument and controlling a tempo associated with said program played by said handheld musical instrument based on said detected gestures.

A foot-operated pedal for programming audio and other effects, including an HMI or Human-Machine Interface that digitally communicates with a CPU, providing the parameters of effects set by the user, where a PC Interface is responsible for the mediation of the communication between the CPU and an external computer used to program the settings and adjustments of the device, with the audio interface having the function of promoting the compatibility between the electrical signal from the musical instrument and the CPU. A graphical user interface to facilitate the creation of an audio effect using icons, a given configuration of icons and interconnections being modeled and employed to generate a given audio effect.

A hands-free music notation display system for playing digital sheet music. The system includes a tablet that displays digital sheet music and houses the system's operating components therein. The housing within the tablet includes a communication link connecting the tablet to one or more foot controls. The foot controls provide the ability for a user to display the next or previous page on the tablet with his or her foot, thereby permitting the user to remain hands-free to play an instrument. The tablet includes a plurality of buttons that permit a user to load and play sheet music thereon.

An arched top bridge upper section including a wood top section slotted to accept a string saddle that may be plastic, bone or similar material. The wood section is laminated or affixed to a lower metal section. A slot completely through the wood section exposes a top flat surface of the metal section. A piezo pickup element installed in the slot below a solid or segmented string saddle element is pressed uniformly against the metal section by string pressure on the string saddle to ensure even response on all strings. Transfer of string energy is more efficient than standard all-wood construction, resulting in greater sustain of plucked notes and a broader frequency response. An arch top guitar utilizing this bridge construction has more similar tonal and sustain characteristics to a typical flattop acoustic guitar while consistent contact with the piezo element results in even string-to-string output and response.
