you are proving my point, now I have many VST's most of those offer sync to host or keep their native tempo but generating a drum beat in those VST's is always in time/ length so basically before creating a song I have to come up with the right tempo and I can not change my mind in middle? that does not seem very creative/productive..if following this rule BIAB VST have to be the first in chain and I am suppose to be stuck with whatever tempo I decided at the start of the project otherwise length of the tracks will mismatch this is unfortunately a serious shortcoming..
