Greetings everyone, I’m trying out MG3 beta and it will not load onto Logic Pro at the moment. First of all it asks for a 256 size buffer and when it is set correctly it says that it is an unsupported buffer size (0) and is just frozen on that. I tried saving the file and rebooting the system and I get the same results. I’m on Mac M1 Max with OS 14.3 and Logic Pro Version 10.8.1 (the latest version)… Maybe I am missing something? Will persist trying to get this working, any suggestions?
There is a run on all system here, and I dont have time today 
But it’s happening because MG doesn’t get audio from Logic.
Make sure your guitar audio track is set to get live input.

Thank you very much, Solved! Audio must be present to open…
The only message I got when trying to use in Logic was, Logic is 48. and MG3 was asking for for 44.1.
I had this……
Change logic sample rate to 44.1 in
