Apparatus and method to enhance the expressive qualities of digital music

摘要

The present invention disclosed an apparatus and method for capturing directly the dynamic motion of a finger to create digital music with enhanced expressive qualities through the use of a capacitance sensor that is configured to continuously produce an analog output of capacitance change upon the approaching but not yet touching, touching and leaving the key or space between keys by a finger.

主权项

1. An apparatus for generating music, comprising
a board with an array of keys and each key is associated with a music note, a capacitance sensor placed underneath the surface of each of the keys, a processor, memory, a program stored in the memory and configured to be executed by the processor, wherein each of the capacitance sensors is configured to detect a touch action by a finger and to continuously produce analogue output of capacitance change for the duration of the touch action, wherein the program is configured to generate a digital profile of the capacitance change of a touch action or a set of touch actions, and wherein the digital profile comprises a parameter selected from a group consisting of distance, velocity, acceleration, deceleration, force and duration, wherein the program is configured to determine that the digital profile corresponds to a certain music playing action, and wherein the program is configured to apply one or more heuristics related to the music playing action and generate a description of music.
