Claim 13:
14. An apparatus for generating a stream of pitch data from one or more touches of a touchscreen, the apparatus comprising:
the touchscreen configured to convert one or more touches of the touchscreen into touch positions having coordinate positions, the touchscreen indicating a plurality of regions of touch;
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 touch position of a touch region;
during an interval when the note processor detects a change in position of a touch, the note processor thereafter converting each 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 pitch data as an output when the note processor detects a release of said touch.
