Claim 19:
20. An apparatus for generating a stream of pitch data from one or more touches of a touchscreen having regions indicated by region indicators, the apparatus comprising:
the touchscreen configured to convert one or more touches of the touchscreen in a particular region having region indicators into associated touch positions having coordinates;
a plurality of key pitch arrays, each key pitch array associated with one of said touchscreen regions, each key pitch array containing a correspondence between coordinates on a touchscreen region and pitch data;
a note processor coupled to the touchscreen and to the plurality of key pitch arrays, the note processor initially outputting a nearest neutral pitch associated with each region of a touch position;
during an interval when the note processor detects a change in position of a touch, the note processor thereafter converting the coordinates for an associated touch position into corresponding pitch data from an associated key pitch array and transmitting the corresponding pitch data as an output;
whereby the note processor stops the transmission of the corresponding data as an output when the note processor detects a release of the touch.
