Ok. It's downloaded and I have the sound set loaded in Sibelius, however several instruments are all messed up! The bass line is a mess. If I push one key on my midi controller, it plays a completely different note in the Kontakt player. For example, if I play a C, it plays an F sharp, and then D will play and E. It does weird stuff like that.
The marimba instrument only plays rolls even if a single stroke is written. It's a mess. What's going on?
