1. A sensor, configurable as a piano keyboard member or a piano pedal member, for transmitting a feeling of playing a real 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, the signal comprising other parameters depending on whether it comes from a keyboard member or a pedal member; and
at least one membrane in contact with the push button and positioned between the push button and the signal generator, the membrane comprising at least one protrusion comprising a first protrusion stage and a second protrusion stage, wherein the first protrusion stage is configured to be longer than the second protrusion stage, thereby enabling each protrusion to deform in two stages under an effect of the push button pressure,
wherein the signal generated by the at least one signal generator is indicative of one of a plurality of musical dynamics based on a number of time sections elapsing between the deformation of the two stages within a time interval or between two time intervals.
