Sameer, Hinrich,
If you don't play your oboe and let it get so dry that it shrinks (over
the long run), you'll need to break it in again--carefully--or it will
crack when you play it and the dry wood absorbs new moisture.
This is one reason that you shouldn't leave your oboe sitting on the peg
for days--it drys out and cracks.
This doesn't mean, however, that you put your oboe away without swabbing
it. If you put the oboe away with moisture droplets in the bore, the
bore will absorb so much water that it expands (in the short run) and
cracks the outer part of the wooden body which doesn't contain so much
moisture and can't expand enough to keep up with the bore.
The reason you keep the Dampit in you oboe case is to keep the outside
of the oboe somewhat moisturized, so that when you blow moisture down
the bore while playing the instrument, the whole wooden body of the oboe
expands at about the same rate--so no cracks.
In the long run, repeatedly submitting the bore to moisture absorption
and then letting it dry out (in the case) causes the bore to shrink and
go sharp and get blown out (irregular intonation).
