And that's how I interpreted what Bob wrote!  It doesn't make any
sense at all otherwise.

To be exhaustively explicit, my tracker bar has, from left to right,
the following hole pattern: (I'm doing this from memory, so bear with
me if the placement of the sustain hole is mixed up):

- two small staggered holes which connect to the pneumatic
    automatic tracking device
- a large hole which connects to the sustain pneumatic¶
- a wide narrow slot, connecting to the bass expression unit¶
- the 88 playing note holes¶
- another wide narrow slot, connecting to the treble expression unit¶
- two more small staggered holes, also connecting to the pneumatic
    automatic tracking device.

I've ignored references to the solodant on/off, play/rewind and
sustain on/off slide valves.

I would tend to refer to "all the holes in the tracker bar" generically
as "tracker bar holes".  Otherwise, they are all unambiguous.
