The main problem with mediabay is that its barely and shamefully represented. Due all respect with tutorials out there but 95% of them covering just basic on the mediabay without scratching full potential of it. Steinberg is somehow act like they dont care limiting its promotion to right zone mediabay 
Unfortunately there are some things that are not completely ilogical/confusing there and you have to make way around which saying in favor that the @steve as experienced user didn’t expect to find it in character tag field, what less experienced user can expect than? Ofc this is subjective thing but with proper promotion and guidance everybody will be better informed and half of questions about mediabay wont be necessary cause users will be already familiar with.
I still know mass of artists that are still browsing samples through import from pool lol
For me Mediabay is one of the best things that Cubase have to offer and could be proud of.
