My piano has the tracking pneumatics tubed from the stack itself.
When the stack is exhausted for rewind, this cuts out the vacuum to
the tracking pneumatics.  It still doesn't work right.  Some rolls
play fine, others are a mess at certain spots because the tracking
pneumatics can't keep up with the side to side slop created during
previous plays and reroll.  It is very frustrating to hear the piano
playing just fine and then playing in a sorry combination of two keys
at once!

Now what?
