I think I have solved the problem of getting the right bpm when analyzing for the first time in engine prime, instead of some house being 64 bpm and some breakbeats being 80bpm. Drag over into the collection as normal but disable (auto analysis) so then go to files and put say one folder in a crate. Then right click and highlight each track. Then perform analyze. Then it seems to do it how it should. Just doing it now theres a program to buy but wanted to see if I could do it with ease.
