I feel the same way, I would rather have few but great libraries for each instrumentation, than a ton of different ones. The Infinity seems like a great combination of playablility, sound and price. I don't really write much yet since it's a hobby, mainly have free libraries. But I want to write film/game music and just orchestral in general.Personally, they already have. Strings remain to be seen. Maybe it's my ocd but I just want a clean template where the Brass and Woods can play most articulations. This allows me to do that. And I'm good with the tone.
And this stuff is easy on the template size and resources.
As far as a single choice goes, you're likelier to like it than not.
Can I ask, what kind of music do you write?
Those tracks are amazing! I have had trouble finding anything using these instruments alone - I misread your post because I thought SMS was something you layered it with, until i realized it was the strings.I don't want to post them again, look at the previous page and you will have my answer about this.
