It occurred to me that BIAB will never really run out of features because they keep putting in new real tracks and this is a bottomless pit. That is primarily why I went from 2012 to 2016 in 4 years (to get the full set of real tracks). It had a few new useful features but that was not the reason for purchase. Two group members who have BIAB complained about my midi tracks :-)
I've always felt very strongly this way about the updates, and all the more so after upgrading to 2019. I think there are enough folks on here that seem to care primarily about the RTs such that BiaB has simply gotten complacent--which is a shame--because it's probably one of the main reason that, among the plethora of music and instrument-related forums I frequent, I last saw BiaB mentioned in 2015 or something. The program just gets more and more dated and hobbled, but instead of fixing the damn thing, they keep piling on more RTs like a deli owner that keeps adding more mayo to the tuna that went off two days ago and needs to be replaced.
