I recently got an Orchestrator and unfortunately it's got some issues.  I want to try and do 
some repairs myself since I think that I can manage with most of the problems.  There's only 
one thing standing in the way.  I have no idea how to open this thing.  I can get the back and 
the control panel off, but I need to get at the bottom of it to look at the keyboard 
mechanism.  It looks like the thing is nailed together or something.  I spent some time 
staring at the problem, but I'm at a loss.  Any tips?
