Abstract
Different aspects of the invention implement a sensor module that can be configured as a keyboard module or as a pedal module, allowing to connect a plurality of keyboard and pedal modules to assemble a configuration to the user's liking, such as, for example, the usual configuration of an 87-key piano together with two pedals. The sensor module transmits information about detected key or pedal strokes to a computer application for playback, either aural or visual. At the same time, the sensor module allows, both in the keyboard module and pedal module configuration, to transmit the feeling of playing a real piano.
Claims23
A sensor, configurable as a piano keyboard member or a piano pedal member, for reproducing a piano, the sensor comprising:
- at least one push button;
- at least one signal generator configured to generate a signal indicative of musical dynamics performed when the push button is pressed;
- and
- at least one membrane positioned between the push button and the signal generator, the membrane configured to deform under an effect of the push button pressure once the pressure exceeds a threshold,
- wherein the at least one membrane is configured with two protrusions of different lengths to deform in two stages, and wherein the at least one signal generator is configured to generate the signal based on the deformation of the protrusions.
A method of a sensor that is configurable as a piano keyboard member or a piano pedal member, for reproducing a piano, the sensor comprising at least one push button, at least one signal generator, and at least one membrane positioned between the push button and the signal generator, the method comprising generating a signal indicative of musical dynamics performed when the push button is pressed by deforming the membrane under an effect of the push button pressure once the push button pressure exceeds a threshold, wherein the signal indicative of the musical dynamics is generated based on the deformation in two stages of two protrusions of different lengths of the at least one membrane.
A non-transitory computer-readable medium storing instructions, which when executed by a processor, cause the processor to perform operations including generating a signal indicative of musical dynamics performed when a push button is pressed by deforming a membrane under an effect of the push button pressure once the push button pressure exceeds a threshold, wherein the signal indicative of the musical dynamics is generated based on the deformation in two stages of two protrusions of different lengths of the at least one membrane, wherein the push button is part of a sensor that is configurable as a piano keyboard member or a piano pedal member, for reproducing a piano, and wherein the membrane is positioned between the push button and a signal generator.
A modular system comprising one or more sensors, wherein each sensor comprises:
- at least one push button;
- at least one signal generator configured to generate a signal indicative of musical dynamics performed when the push button is pressed;
- and
- at least one membrane positioned between the push button and the signal generator, the membrane configured to deform under an effect of the push button pressure once the pressure exceeds a threshold, wherein the signal indicative of the musical dynamics is generated based on the deformation in two stages of two protrusions of different lengths of the at least one membrane;
- wherein at least one sensor is configured as a keyboard member for reproducing a piano.
