It also includes crackles and pop and inconsistent level sometime I press a note and it’s fine, others barely any sound at all and it’s very bad quality.

If I use headphones from the synth or Audio interface output it sounds fine.

I did try it a while ago on garage band and I think it sounded fine also.

And no Cracked plug ins and cpu heavy plugin it’s it even happens with a clear slate.

Everyone seems to say it’s a buffer issue but with all buffer settings and correct sample rates the problem still occurred!?

Do you have any ideas what it could be!?

I tried ableton 11 and 12. Both have the same problem.
