Abstract: A method to alter the pitch of a portion of a music keyboard by a transposition, including: upon a prescribed function key being activated to provide the transposition function for the portion, and upon a music key of the music keyboard being activated; determining if the transposition function has been activated and, if the music key is in the portion and checking a lookup table and altering a note corresponding to the music key by the transposition. Also disclosed is a method for enabling a bending of at least one note produced by a musical keyboard such that, upon a bending function being activated and a range for the bending being selected and set, and upon at least one music key of the music keyboard being pressed by a user to cause the at least one note to be produced and the bending function being instructed, bending the at least one note in accordance with the selected and set range for the bending. Keyboards for performing the methods are also disclosed.

Abstract: 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.
