Hi,
well as said I know how to beatmatch but this isnt the problem here.
When using two tracks that are on 124 (not sure if any producer produces on tempo like 124.05 or something like this. I never did and never will) and setting the speed to 124 on each deck I would expect the tracks to run in sync for ever.
However it really might be rekordbox or the absence of it. i tested two versions of the same track i finished yesterday just differing in subbass mixing and they run 100% in sync all the time without sync being set to on.
i really have to check if this happens just with me playing b2b with my friend or also just me playing (all my tracks went into rekordbox, which is a nightmare by the way).
if it happens just with my tracks i will do a video and post again.
thanks for helping
