just got an email.  OTS has updated Evolution Acoustic Steel String.  It brings it up to date with the new engine.
 
From the email:   "This update brings Steel Strings into the new Evolution guitar engine, premiered by our recently-released Evolution Electric Guitar - Stratosphere library. The update has countless new features and improvements, including a built-in strum pattern editor, an improved effect system, integrated factory presets, and much more."

I am just LOVING the new engine on both Stratosphere and Strawberry.... it is totally rad, awesome, unbelievably playable, and by far the most amazing guitar VST engine I've ever played and as you can see from my sig, I gots me bunches... i'll probably never use again now that Evolution Acoustic Steel String has been updated.
 
I was very frustrated with the last engine and that's why I started acquiring other "guitarz"... but man, Greg you have finally done it!  Thanks!!! Can't see using any of the others much if at all anymore!

Dang, you guys are fast! Just posting the official announcement in a few minutes. ;)
