Multi-touch piano keyboard

A musical keyboard touch sensor pad comprising:

• (a) a plurality of integrated touch sensors disposed in an array, the plurality of integrated touch sensors representing a keyboard key, wherein each of a first group of the plurality of sensors are generally saw-tooth shaped and are longitudinally arranged adjacent to each other;
• and
• (b) a processor electronically coupled to the plurality of integrated touch sensors, the processor being programmed to receive input from several of the plurality of integrated touch sensors and to generate a sound signal based on the input from the several of the plurality of integrated touch sensors, the sound signal being variable based on the number in the plurality and the location of the plurality in the array, wherein the processor is adapted to process a touch moving back and forth on some of the plurality of touch sensors and to generate a vibrato signal based on the back and forth movement.
