From what I mentioned, only multiscript is a Kontakt full version feature. All the other stuff is also relevant with the player. So, for example, even with Kontakt player, instruments load samples to ram in the background, but that isn’t really the point ... most professional composers have the full version, anyway. And that is not only for being useful as a sampler recording your own material, it also helps with adjusting the libraries to your liking. Even if you just use the libraries out of the box, there is a lot that can be done to customise the way you use those libraries. And that has also to do with multi scripting, which uses a similar scripting language as instrument scripted, but is a separate thing. You can completely adjust the midi going in and out of your multitimbral Kontakt instance using it. To make a simple example, you can change incoming CC 1 on channel 1 to CC 11 on channel 2. Only a very simple example, of course ...Isn't the more appropriate comparison right now Kontakt Player and not Kontakt? Everyone is trying to compare the Spitfire Player to a _sampler_ not a sample player.
Yes, Kontakt proper has a bunch of features that Spitfire Player doesn't have today. It also has a bunch of features that Kontakt Player doesn't have, too.
All of that functionality is currently impossible to replace when you host in VEpro. Part of the functionality can be replaced, when you host directly in Cubase or Logic (through midi inserts or the environment).
The aspect of being able to use your own material in a spitfire sampler is going a step further than what is being discussed here. We may remember the announcement of Play pro in this case ... but really, that is not even what I am talking about when I compare the current thing to Kontakt.I'll accept that Spitfire has a roadmap for their player, and maybe even to extend it to have more Sampler-like features. They aren't just popping open the Spitfire Player and loading samples into it-- there's another piece of software that is essentially their library builder that presumably has scripting and setup they use to build these libraries. For now it's just for them. Maybe some day it'll be polished for everybody.
