The present invention relates to an application for an iPad or similar electronic device having a touch screen. It provides a sensor to detect the touch position along the vertical length of a key as it is being engaged and to then offset the notes of the keyboard accordingly. This enables several octaves of notes to be accessed on the touch screen at any given time with a key size that is sufficient for real time playing. This arrangement further enables the incremental offset of the note pitches in a continuous manner to emulate the “string stretching” and “fretless neck” techniques of guitars and basses. The invention further provides a screen overlay to physically define the borders and travel of the on-screen keys thereby emulating the tactile feedback of real keys, again in a manner sufficient for real time playing. |
