When running your hetro analysis, try a lot more initial breakpoints (n
option). Have it work out to about .005 seconds between breakpoints. Also
use a lot more partials (h option). Try 512 or 1024. There may still be
trouble with sharp attacks, however. If hetro doesn't catch it, adsyn can't
make it.
