M1 MacBook Pro Sonoma 14.3. (Error was occurring with Monterey also)
Logic X 10.8.1. (Error also occurred with 10.7.x)
BFD 3.4.5 build 28.
I get this messaged well over half the times I open empty (or existing) projects up as soon as I try to add BFD3 to the project. It’s not due to the midi 2.0 setting as that setting is not checked.
