I am having a problem retubing the tracker bar in my Schulz Aria Divina
Grand Recordo.  I was able to retube the existing expression tubing
easily by following the old tubing and the Schulz Tubing Diagram from
John Tuttle, but a lot of the key pneumatics tubes were missing and
I am not sure which ports should be left empty.  I have 100 ports in
the tracker bar and only 82 key pneumatics in the stack.  Thirteen
ports are assigned.  The ports assigned are as follow, left to right:

 1. Tracker
 2. Switch (another story here)
 3. Hammer Rail Bass
 4. Open
 5. Sustaining Pedal
 6. Repeat
 7. Rewind

Right side:

 95. Pressure 35
 96. Pressure 19
 97. Pressure 15
 98. Pressure 12
 99. Hammer Rail Treble
100. Tracker

These account for 95 of the 100 ports.  So where do I start tubing the
tracker bar for the key pneumatics?  I would appreciate any suggestions.

Thanks,
Brice Willis
