This is an issue we know about/should have a hot fix for later today if not tomorrow. Essentially, logic added in Midi 2.0 as an option in Logic 10.7.8, and running M1 native, there's a discrepancy issue because Opus sends out Midi data and Logic is reading it wrong because since Logic 10.7.5 M1 native plugins (when you run it natively) are loaded outside of logic rather than within the system. Until we have that fix available, you can run Logic in Rosetta (right click logic in your applications, choose 'get info' then select to open in rosetta) and you shouldn't have that problem, but I'll send you the link for the updated fix as soon as I have it.
