Quick update for anyone interested. I suggested to the AS folks that they take a look at this old thread to understand the problem people were having. I think they must have. I got a follow up thank you from them in which they stated that they have now changed the default start time to 35ms (quite usable for real time playing).
Someone had questioned if there is a vst3 version. There is, but it is not currently handling midi cc like aftertouch so I think it is being pulled from their server until that is sorted out.
My first impressions of the AGG are very positive. Great sounding instrument, a little cheaper than some others and the developers are quite responsive.
