I need of information as to how the xylophone On-Off valve switch
is connected.  Everything is working on the machine -- xylophone,
piano, snare drum, mandolin and triangle.  I just can't get the
xylophone to turn off and on.  I now have it on all the time.

A schematic diagram or tubing sketch of how the valve is piped into the
system would be extremely helpful.  I am playing style G and 4X rolls.
Channel 27 is xylophone off and 29 is xylophone on.  I just can't figure
out how to tube the machine to get the xylophone to turn on and off.
I can send photos of the on-off valve if that would help.
