Disklavier

With all the recent interest in the 2004 Piano e-Competition files, 
I was reminded about a question I never posed about the 2002 Piano  
e-Competition files.

In addition to the usual "GM System On" (F0 7E 7F 09 01 F7)
and "XG System On" (F0 43 10 4C 00 00 7E 00 F7 ) SYSEX
messages, the 2002 Piano e-Competition files also include the 
following SYSEX message:  F0 43 71 7E 0A 00 F7 

Anyone know what this SYSEX message does?  I can't find any 
reference to it in my Yamaha SYSEX info.


Regards,

Robert
