If you're annoyed that there's no picture of the soundbank, you can add a photo to any soundbank here:
Windows:
C:\ProgramData\Arturia\Shared\images\vc8_images\packs
Mac: (probably)
Mac HD/Library/Arturia/Shared/images/vc8_images/packs/
Only the Discover version of the piano is free. You have to pay to get the other 2 versions.
You must've tried out the free version, it's horrible. The other versions seem great although they don't have a lot of velocity layers.
It's on sale, $35 instead of $59.

I haven't bought it but it seems great value after the update.
