I am glad to see this back on the forum once again. Like most of you I really like real tracks and use them whenever I can. Like real musicians playing parts live sometimes you get what you want and sometimes you don't. I plan to continue buying future upgrades because BIAB is my primary tool for generating back up tracks. . BIAB can be made much stronger if users can easily find, audition and blend various instruments as needed. There are hundreds/thousands of great parts. I firmly believe that dollar for dollar R&D spent on a sophisticated interface for finding the parts will bring greater interest/sales etc than any other area.
BIAB is not alone with this concern. I sometimes use EZ Drums and with the thousands of patterns finding the right pattern is really dificult. Perhaps a drag and drop tool of each pattern via plugin could be an option to replace or supliment the grid for frequency of a pattern being played. This is more tedious for the casual user but gives the user ultimate control. Hoping to see more MIDI focus along with the RTs from PG.
