NP4 and Cine Series for Kontakt

I updated to NP4. I am looking to purchase CineStrings Solo, on sale for a very big reduction now. The NPPE engine application recommends 128GB RAM.

Is this truly required? I am limited to 32GB RAM at present. Is this a requirement for CineStrings or NPPE?

For just the solo strings 32 is fine. I’d be hard pressed to recommend them though. The cello is particulary weak. And no vibrato control… ymmv…

Any superior suggestion? I am still searching. As I mentioned in another topic, my use case is string quartet.
