The Thumb Bar Controller is a bar that runs the width of the electronic musical keyboard playing area, (plus whatever is needed for the lever attachment), connected by two armsrests just below the top, and approximately one inch away from the keys. It gives the performer control over two (or more) functions with the thumb of the playing hand, that would otherwise require the other hand or foot pedals, allowing a person with the disability of one arm/hand, to be as proficient as a person with two. It can be used for controlling pitch bend, modulation, MIDI specification controllers, various electronic controls, and product specific controls. The bar can be attached in numerous ways, could use a variety of spring type mechanisms to control it. It can be mounted externally or made as an integral part of the keyboard, with openings for the bar connections and movement required.

The present disclosure relates to systems, methods, and devices for music simulation. The methods may include determining one or more simulation actions based on data associated with one or more simulation actions acquired by at least one sensor. The methods may further include determining, based on at least one of the one or more simulation actions and a mapping relationship between simulation actions and corresponding musical instruments, a simulation musical instrument that matches with the one or more simulation actions. The methods may further include determining, based on the one or more simulation actions, one or more first features associated with the simulation musical instrument.

Methods and digital circuits providing frequency correction to frequency synthesizers are disclosed. An FLL digital circuit is provided that is configured to handle a reference frequency that is dynamic and ranges over a multi-decade range of frequencies. The FLL circuit includes a digital frequency iteration engine that allows for detection of disappearance of a reference frequency. When the digital frequency iteration engine detects that the reference frequency signal is not available, the oscillator generated frequency is not corrected, and the last value of the oscillator generated frequency is held until the reference frequency signal becomes available again. This FLL circuit is also preceded by a low-pass filter which is dynamically tuned to the frequency to which the FLL locks, eliminating harmonic components in the original signal which might otherwise cause errors in frequency estimation.

A method and system for selecting an instantiation point for a virtual asset relative to a physical space, the method including and system operable for: prompting a user to place a device at a desired position/alignment in the physical space; capturing the position/alignment with respect to a real world frame of reference; translating the position/alignment with respect to the real world frame of reference to a frame of reference in virtual space; and spawning the virtual asset in the virtual space at/with the translated position/alignment. The device includes one of a smartphone with a camera and a 6 degree-of-freedom controller.

A monitoring device for monitoring a passenger transport system includes at least one sensor, a control unit, a bus, and at least one bus node connected to the bus. The bus node has a microprocessor and an inspection unit for data exchange with the control unit. A first program module in the microprocessor detects a state change of the sensor that is connected to an input of the microprocessor via a transmission line and spontaneously transmits a corresponding state message to the control unit. A second program module in the inspection unit, after receiving an instruction from the control unit, transmits an activation signal to a coupling point in the bus node that simulates a state change of the sensor, the activation signal being superimposed on a sensor signal and/or being coupled into a power supply line connected to the sensor.

A musical sound generation device includes a control device which, when a performance operator among a plurality of performance operators has been operated for a part that has been set to sound a predetermined number of simulated voices of an analog synthesizer, assigns a sounding parameter of one or two or more voices, which form a timbre of a simulated voice of the analog synthesizer corresponding to the operated performance operator and are selected from a plurality of sounding voices, to a sound generation circuit, and assigns, to the sound generation circuit, an information set selected from a plurality of information sets and each include a variation value that applies a variation to the sounding parameter of the one or two or more voices, and a sound generation circuit that performs a sounding process of the one or two or more voices using the sounding parameter and the information set.
