A musical keyboard system for an electronic musical instrument, the keyboard system including a sensor arrangement for determining the amplitude of a note produced by a key of the musical keyboard, the sensor arrangement including a first sensor for providing an indication of a first time when movement of the key activates the first sensor, a second sensor for providing an indication of a second time when movement of the key activates the second sensor, a calculating device for determining the time difference between the second time and the first time, and an amplitude determining device for determining into which range of a plurality of ranges of time differences the time difference falls, and which amplitude of a plurality of amplitudes corresponds to the range. A corresponding method is also disclosed.
