Midi Clock between external sequencer and DAW

Hello to all,
I come to you to try to find a solution to my problem.
Indeed, I try by all means to synchronize my Arturia Beatstep and or my Nektar Audio with Reason or Ableton.
And I always meet the same concern, that is to say that it notes sent sound late (control of delay does not change anything) but especially that they are random.

On a 1/4 loop, the first keystroke will always be a few ms late and if I loop, each keystroke it taps a few seconds apart.

I tried to change the Usb port, to change the cable, to change the sound card, to change the external sequencer, nothing to do the problem persists
I also tried on Ableton, same fight.
I updated all my drivers. and as it did not work, I even redid a new installation of Windows 10. but I dry royal.
It's not a latency problem in my opinion since it plays (check with midi view) each note has 3ms of difference.

I implore you to help me! I'm very angry.

Thanks in advance.
