Hi, I have been a long time BIAB user for mac. I think it was like version 5 or 6. But for many years I have been very disappointed for the lack of support on the mac side over the years and I am very hesitant to upgrade to the newer version because of this. On the PC side, every year, there was always a new version out. but on the mac side, it was like every 2-4 years for a new update or new version. Currently I use version 12 with a softsynth called Sampletank using IAC drivers which works great ,sounds great, and very stable too. The sound is 100x better than the built in QT instruments or any of my outboard midi gear I have. Now would it make a big difference if I upgraded to the new 2010 in sound quality using the realtracks or the realdrums loops? Also does the new version support VST instruments or does is still require IAC still to use standalone softsynths like sampletank? Just a few concerns I have about the new BIAB.
