Disklavier Service

[Greg Newell]

Yeah! Press down on key numbers 88, 87 and 86 while you pull out the 
action. :-) JUST KIDDING!!! Once you see it you'll remember. The beauty of 
the Yamaha disklavier is in it simplicity. Fewer connections leaves less 
chance to screw something up. Be a little more careful than you would your 
standard action as that rail across the top of the hammer shanks can be 
messed up if the screws were left a little loose. If you put any pressure 
on that rail you could mess up the efficiency of the playback and recording 
as that's where it measures hammer movement and velocity. I don't know how 
much your doing to the action but watch that you put back everything as you 
found it. Most important and to be done FIRST is a record and playback 
test. Get a blank disk from the owner and if it's not formatted do that. 
Have it record while you play each note chromatically and then soft and 
sustain pedals. Have the Dsiklavier play it back to make sure it all works. 
This is good insurance to prove everything either worked or didn't when you 
got there and hopefully does or still does when you leave!!! Hope this helps!
