Recommendation needed for realistic AUv3 instrument!

So Audio Modeling have released their apps and I’m blown away, suddenly I found my self hungry for more.

I have experiment with sample tank while back and it was quite underwhelming.

I have plenty sounding synths and keys, but would be great if someone could recommend more strings or anything that sound good?

Cheers!

For anyone interested have a look at my improv with SWAM Flugelhorn
