Interface device to couple a musical instrument to a computing device to allow a user to play a musical instrument in conjunction with a multimedia presentation
First Claim
1. An interface device to couple a musical instrument to a computing device, the computing device to perform digital signal processing (DSP) on a digitized audio signal of the musical instrument received from the interface device to create a processed digital audio signal of the musical instrument, the computing device to present a multimedia presentation of a digital audio file to the user and to create a mixed digital signal of both the processed digital audio signal of the musical instrument and the digital audio file, the interface device to cause the mixed digital signal to be converted into analog form for transmission through an analog sound device to the user presenting sound to the user thereby allowing the user to play a musical instrument in conjunction with the multimedia presentation, the interface device comprising:
- a processor;
a digital to analog (D/A) converter to convert the mixed digital signal of both the processed digital audio signal of the musical instrument and the digital audio file received from the computing device into a mixed analog audio signal; and
a digital audio interface to control timing and formatting of the digitized audio signal of the musical instrument and the mixed digital signal;
wherein the processor controls the digital audio interface such that the mixed digital signal is transmitted through the D/A converter and through the analog sound device to the user to allow the user to play a musical instrument in conjunction with the multimedia presentation of the audio file.

Abstract
Disclosed is an interface device to couple a musical instrument to a computing device to allow a user to play a musical instrument in conjunction with a multimedia presentation. The interface device comprises a processor, a D/A converter, and a digital audio interface. The computing device creates a processed digital audio signal of the musical instrument based upon an original digitized audio signal of the musical instrument from the interface device. The D/A converter then converts a mixed digital signal of both the processed digital audio signal of the musical instrument and a digital audio file received from the computing device into a mixed analog audio signal. The processor controls the digital audio interface such that the mixed digital signal is transmitted through the D/A converter, and ultimately through an analog sound device, to the user.
