There is also a good review on the website with more audio samples which you can translate using Chrome browsers or Google from Polish to English if need be....

DNC
Great Strings, Woodwinds & Guitars, however not impressed with the rest

Pianos
1 or 2 passable ones, but overall not impressed, also when changing voices the sustaining sound of the previous voice appears to get cut off which is not really acceptable these days.

Styles
Great drums but the rest of the sounds don’t appear to integrate very well with them; also many of the styles demonstrated seem very disjointed as if the different parts were done by different style designers.

Vocal Harmoniser
Never use one so can’t comment.

More proof of how muffled the voice sounds .... such a shame. She sings nice.
