Abstract

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.

Claims

1. A piano-type keyboard apparatus including:

a plurality of piano-type keys, each of said keys having a length;

one of said piano-type keys being designated a detection key and including touch detection means for detecting the point of touch along the length thereof, and

control means for controlling a function of said piano-type keys in response to said touch detection means.

2. The piano-type keyboard apparatus as claimed in claim 1 where said function control includes means for the setting of the musical pitches of at least some portion of said piano-type keys.

3. The piano-type keyboard apparatus as claimed in claim 1 where at least some portion of such touch points so detected on said detection key are each associated with some musical pitch.

4. The piano-type keyboard apparatus as claimed in claim 1 where upon such touch point detection the musical pitch of said detection key is set to the musical pitch so associated with said touch point.

5. The piano-type keyboard apparatus as claimed in claim 1 where the musical pitches of at least some of said piano-type keys in proximity to said detection key are set in accordance with the musical pitches of a similar portion of piano keyboard keys in similar proximity to the piano key whose musical pitch relatively corresponds with said detection key musical pitch.

6. The piano-type keyboard apparatus as claimed in claim 2 further including at least one pitch selection means to select the musical pitches to be so associated with said touch points.

7. The piano-type keyboard apparatus as claimed in claim 6 wherein said musical pitch selection relates to at least one musical key.

8. The piano-type keyboard apparatus as claimed in claim 7 wherein said musical pitch selection relates to at least one musical octave.

9. The piano-type keyboard apparatus as claimed in claim 7 wherein said musical pitch selection relates to at least one musical note.

10. The piano-type keyboard apparatus as claimed in claim 7 wherein said musical pitch selection is in some part in accordance with one or more musical cents.

11. The piano-type keyboard apparatus as claimed in claim 1 wherein at least a portion of said piano-type keys can function as piano-type touch screen keys.
