Disklavier

I have seen Disklaviers used in theatre work.  Your singer could play a few
notes, then the Disklavier could be controlled remotely through a MIDI
connection. It worked at the Kennedy Center.  Or you could just hide the
remote control where she could press Play and start the accompaniment
instead of a key that "shows up".  For some silly reason, I don't think
Yamaha is being secretive - it's just knowing who to ask.  Most Disklavier
technicians and salespeople don't even know what sysex codes are. Maybe
PianoBench could help you to make your own SmartKey arrangements as he
probably knows more about Yamaha MIDI than anyone else.

BTW, neither Maintenance Mode or Test Mode are no big secrets to access.
The only reason they aren't included in your owner's manual is that if you
press the wrong button  you can put the piano into the wrong language or
worse yet, tell your DKV it is the wrong model and nothing would play right!
Like most mechanical things you buy, these modes really don't have any
"user" functions.

Until you find your sysex codes, why don't you explore some of the other
capabilities of the DKV like remote access, time-delayed start, the foot
pedal switch, etc.  With MIDI, there is usually more than one way to do
things!  Meanwhile, good luck and Happy New Year!
