I'm using the "ConcertGrand with overtones by Olivier" from the NI Akoustik library in Kontakt3 to play back a piano part in Sibelius 5.2.5 on an intel MacBook Pro with osx 10.5.6.

Whenever the sustain pedal is used, the previous note is also sustained. So are any notes that were being sustained when that previous note started. During passages where the sustain pedal is lifted briefly and pressed again, it plays back as if the pedal was never lifted.

This doesn't happen when I use piano sounds without release samples, but they don't sound as good. Is there a relatively easy way to fix this? Solutions that involve scripting are fine--
