Hi, I have the same problem as Glenn, I've been researching how to have better midi sound in biab for some time.
I have the free version of the kontakt and I hesitate to buy the full version because I see that it does not come with too many instruments, would I have to buy or search for banks of instruments later? I use biab for jazz standards.

I also appreciate the sampletank, it seems easier and brings more instruments from the factory.

I am very confused now and I have downloaded sounds of heaven but I don't know how it installs and how I can choose it in biab.

Any help in this regard will be welcome
