New digital audio format on the way?

A new audio standard (.MT9) being proposed offers the listener the option to control the volume of certain instruments via a 6-channel equalizer.   This would be especially useful for karaoke fans, but I would be more interested in using it as a training tool to analyze guitar parts, or just simply mute them so I can play along.  You can do this now with MIDI interpretions of existing songs, but midi tends to sound too artificiial even when played through high-end sound cards.
