I think the problem is not within the sampler, but rather how you use the
instruments in the mix. If two instruments are playing exactly the same
audio files, and if they are time-shifted a little, then you get
phase-cancellation artifacts. If the samples are played at the same time,
all that happens is an increase in volume. It's analogous to the phase
problems you sometimes get in using multiple mics to record a source, if
they're not set up properly.

I noticed this problem using two patches from the Garritan Orchestral
Strings, for example. If I had two tracks in the Arrange page with identical
sequences, one with an All Violins legato patch and the other with the first
violin legato, and one of these is slightly delayed relative to the other,
then I'd get phasing because the All Violins patch includes the identical
1st violin samples (along with the 2nd violin samples, which of course
wouldn't contribute to the phase cancellation because they're different
samples.) It would be important in this case to use only the all violin
sample or blend the 1st and 2nd violin patches.
