Don't find anything about it here, so here is the Pb :
When I load a K2 patch from a piano library that have been converted from Giga it happen the following :
Release samples are not played when sustain pedal is down (ok, this is normal), BUT they are triggered when I release the sustain pedal !!
I don't have this Pb with Kontakt 1.5.3 : release behavior is ok.
The only way I have found to solve this in K2, was to delete release groups, and create a second instrument, specific for release samples.
This happen for the piano I've converted myself (K2 import) from Giga. This also happen with Kontakt patches from sampletekk (including TBO demo).
Anybody having the same problem ?
