That has a great sound. But it is essentially one timbre of sound. The company that makes it makes many virtual instruments.
But it is not as complex or as evolved as BIAB. This particular software appears to be a virtual instrument. BIAB blends multiple virtual instruments ("real tracks") achieving convincing accompaniments and solos. Your attitude about BIAB was formed years ago when you bought a copy and does not reflect what BIAB has become and importantly, is becoming.

Nonetheless...Native Instruments Komplete has a lot of real good stuff. Thanks for posting. I had never looked at their acoustic guitar VSTs.
