I just installed Logic on a brand new Mac mini M4 using Sequoia 15.2 and after loading NI on here, noticed nothing using NI instruments was playing on old tracks. I was previously using an older machine that is now scrapped, and saved everything on an external drive. After reading other threads on here, it was suggested that I uninstall Komplete Kontrol 3 and install 2.9.6. I have done so and it didn't help. I have tried launching Logic in Rosetta mode and that made it even worse.
Luckily on some tracks, it at least shows what plug in I actually used so I just go and dig it out to select it and it now plays. This is extremely time consuming but at least gives me some hope. On others, it is not there so not really sure what to go on.
As someone who is more focused on making music than navigating this software and its updates, can anyone please provide any other troubleshooting tips on what I can do to get all my old stuff back and playing? Thank you very much.
