Hi All

I have a CVP 209, so I was wondering which set of files to download 
from the 2004 International Piano-e-Competition. Should it be the XP, 
Enhanced or the Eseq. So I went for all three. Having listened to the 
same song on all formats I can't hear any differences.

Now here is a question.  Looking through the midi files of the XP 
format I have found a lot of Ctrl 16 and 81 commands.
My CVP does not use these so there is no mention of them in the 
manual.

Can someone with a PRO, have a look in their midi data book and let 
me know what the two commands do? I hate not knowing what all these 
commands are for.

Thanks
