FIG.1 
(57) Abstract: A system consisting of method and device for real-time synchronization of MIDI generated sounds with audio program 
CA material originating from a Digital Audio Workstation (DAW) (205). The present invention provides a real-time feed-forward control 
= system for the generation of sound arising upon the execution of MIDI commands time-synchronized with the playback of audio 
program material. The system uses one or more audio synchronization tracks (219) to accomplish synchronization. An audio interface 
00 device (102) converts the data streams created by the playback of audio program tracks (201) and audio synchronization tracks (219) 
into electrical audio signals. The proposed MIDI interface device (103) uses the audio synchronization signals (219) output by the audio 
interface device (102) to strobe or clock out MIDI events (215) waiting on a FIFO buffer inside the device. Finally, the re-synchronized 
MIDI events (227) are transmitted to the sound generating device (104) in perfect synchronization with the audio program material.
