	Patrick,

	I had this problem doing a granular synthesis piece a couple of years
ago (although I made my own granuals, not using the gran inst). Some of
the individual granuals were small enough sound snippets so that they
were really closer in size to a few sample points. They became arranged
in such a way as to become a high frequency sin wave that sounds like an
unfriendly bi-product.  So my solution was to make sure that all sound
snippets were large enough to avoid this, but another approach would be
to apply a noise gate or carve out the sound in the frequency range of
the piercing high end squeal.

	hope this helps,
