Alright, Imma let you finish, but first let me just say this - SampleTank is specifically designed to be a ROMpler replacement. Kontakt is a sampler, and as such, is only as good as the sample libraries you invest in (which can be very expensive). The two serve two totally different purposes.
The thing that is nice about SampleTank is you install it, point it to your sounds, and forget it. Everything is just there when you need it. Samplers seem to always have you searching for your sounds, loading them, replacing them, etc.
You can get a choir for Kontakt that is bigger than the entire SampleTank library. That's cool if you want a really hyper-real choir that sounds like you had the tabernacle in your home studio. Not so cool if you want a ton of great sounds with a small footprint and small price tag and fast loading that can hold it's own against a KORG Triton or the like. And that choir alone will cost you more than the entire Total Workstation 2 bundle, not even counting the software. So comparing SampleTank to Kontakt doesn't really fit price-wise.
Virtual instruments are what Native Instruments specializes in. It's even in their name. But analogue hardware modeling, particularly amplifiers, is what we specialize in. And there is no contest there. When the top brands and players want to get in the ampsim game, they come to us, and no one else. There are already plenty of examples like officially certified Ampeg, Orange, Fender, and Authentic Hendrix. And there is more to come. You will know what I'm talking about here very soon. We have a lot going down on the modeling side of things, and this is a very good time to be on board with IK, if you're a real gearhead especially.
