PROs - The biggest pro by far is that VIP will catalogue all your VST instruments, and let you create lists of your favorite sounds

Saves me lots of time searching endless Nexus banks and other vsts to find suitable sounds before the idea leaves

I primarily use Ivory and Omnisphere , but have found some good sounds in the libraries that Akai provides

To me, the option to select a sound just by scrolling, or having a dedicated button to push and select would work better
