Disklavier

My 1990 disklavier C3 (wagon controller) was just delivered 
yesterday.  Luckily, it came with about 40 disks.  Unfortunately, the 
thing plays these disks very loud.  So loud, in fact, that my wife is 
very disappointed with my purchase decision.  From what I understand, 
this is a fairly common complaint, even with the volume on the 
disklavier turned to -10.

In the interest of marital harmony, is there any way to take an 
existing Yamaha disk and modify the files to decrease the volume?  
I've looked through past messages and played around with some of the 
utility files posted on this group, but I can't seem to figure things 
out.  Instead of re-inventing the wheel, is there anyone who has had 
success in this regard?

I was thinking that I could use the program Veloset to decrease the 
volume of some of the files.  Perhaps I can use the various utilities 
to copy the files to my computer, convert the ESEQ files to MIDI, 
decrease the volume using Veloset, convert back to ESEQ, then save to 
new disk.  Would this work?  I'm having trouble even opening the 
EEXPLORE program...I get an error message and the program is forced 
to close.  (I'm running Windows 2000 Professional at work.)

I'd greatly appreciate any help.

Thanks!
