What's wrong with the instruments in the music room?

Have you noticed a recurring theme with the bots on Starship Titanic?

All of their settings seem to be off.

And it's your job to fix them.

Look at the control panel in front of the instruments.  Try playing with that
to see if you can get the instruments playing correctly.

Press the red button in the bottom-center of the panel to start or stop the
instruments.  The four yellow buttons turn instruments on and off
individually.  The other controls determine exactly what the instruments play
(they set pitch, speed, and tune).  But once you've started the instruments
with the red button, you have to stop and restart them for those controls to
have any effect.

There's no way to change the upper-left controls (for the chimes).
