Has this been broken again in the most recent release? I started playing from the previous version (so not the first one with the problem), and I didn't notice any problem, but I've installed the latest version I definitely notice this happening now. Essentially, sample release sounds as though it's just completely cut off if the sustain pedal had been down. Doesn't happen if the sustain pedal was not used; then the normal room release sound occurs.
EDIT: Yes, confirmed; I just reinstalled the previous (1.0.464) version and there is no chopping in that, but installing the latest version (1.0.530) brings it back unfortunately, so that's another for re-patching.
