Abstract
The invention disclosed is a system for playing a music sequence such as a MIDI file in synchronization with a prerecorded digital audio data file, such as an MP3 file. The synchronization is accomplished by using the digital media sample rate as a common time base for progression of the playing of the digital media and the music sequence.
