SYNC = Overbridge versus ITB vst'i : not aligned when bounced

Hi guyz , may i ask you a question concerning your use of overbridge :

New to elektron , one of the thing that made me jump is the tight integration .

I’m using S1 and i experience some issues to make it really synced . (it is synced but not 100 % aligned to be presice )

As a lot of people , when i noticed latency when bouncing audio from soundcard … i get the manual offset right as in any set up . All good here . classic daw set up for good results .

I can even offset midi clips in s1 .

My problem is overbridge versus Vst’is … while those vsti’s are 100 % sample accurataly aligned , overdbridge bounce audio still has an offset , the problem being that i can’t find a way to align it unless i do it manually … offset for audio in s1 doesn’t apply , don’t know why , maybe because it deosn’t see it as an external audio flux , don’t know …

Any idea how to get something tight ?
