PSOLA with complex envelopes?

Is anyone aware of software -- for Mac OSX, preferably -- that implements
PSOLA (Pitch Synchronous Overlap Add) pitch/time shifting and also would
allow control by importable, complex breakpoint envelopes? For example, if
Csound or SuperCollider had a PSOLA objects, that would be work (but they
don't, as far as I'm aware). I'm actually working in CLM, but it is probably
worth it time wise if I have to export to another app rather than take the
time to write a PSOLA algorithm in CLM.

Praat has PSOLA and works quite nicely, but since it can't import breakpoint
envelopes, it won't serve my needs.

Thanks,
