The present invention provides touch sensor means for detecting the touch location along the length of an outfitted piano key as it is pressed, so as to then offset the notes of an associated piano keyboard accordingly during play. When such an outfitted key is pressed in combination with other piano keys, the touch location along the length of the outfitted key, and the separation intervals and timing of the key presses, are analyzed to determine the intended chord, such that before any notes are sounded, the notes of the pressed keys are configured for the sounding of that chord. This arrangement enables playing a wide range of notes using just a few keys, so as to provide a substantially reduced-size keyboard with full-sized keys sufficient for real-time playing. This arrangement also enables configuring the note offsets of those pressed keys to conform to a selected musical key, so as to simplify the layout of the keyboard by eliminating its black keys, while still supporting the playing of non-conforming notes. This arrangement further enables applying pitch variation to those note offsets in order to emulate the “string stretching,” “whammy bar,” and “fretless neck” playing techniques for guitars and basses. This arrangement even further enables playing advanced chords in a simplified manner. Finally, this arrangement enables providing a wide assortment of keyboards that can differ in the type, number, size, and functionality of their outfitted keys. |
