It gives you exceptionally flexible and comprehensive control over the routing of incoming MIDI data. For example, you could use this to selectively play back parts of song data from a computer - having the 9000Pro respond to certain parts of the song, while playing back other parts on a separate connected tone generator (as shown in the illustration). Select the desired THRU PORT settings from the MIDI SYSTEM display (page 174) on the 9000Pro as described below, and make the appropriate port settings on your computer/sequencer software.
