Patent ID: 8180063

Claim:
A signal processing system for generating and/or manipulating sound in real time, including: an audio input for receiving an audio signal; a trigger input for receiving a trigger signal; an audio output for outputting sound signals; a memory for storing a plurality of digital files; a graphical user interface enabling a user to select at least one digital file from the memory and to select a processing scheme; a digital processor coupled to the audio input, trigger input, memory, audio output, and user interface, the digital processor programmed with an algorithm enabling the digital processor in real time, based on the selected processing scheme, to: manipulate the audio signal using the at least one digital file to produce a manipulated audio signal; generate a virtual instrument sound signal using the trigger signal and the at least one digital file; manipulate the virtual instrument sound signal using the at least one digital file to produce a manipulated virtual instrument signal; combine the audio signal with the manipulated audio signal, the virtual instrument sound signal, or the manipulated virtual instrument signal to produce a combined signal; and output a music signal to the audio output, the music signal including at least one of the audio signal, the manipulated audio signal, the virtual instrument sound signal, the manipulated virtual instrument signal, or the combined signal.
