Hello dsparks66,
1- Most important: Following your "how to do", Legacy content is now back/visible in the Library (Y). Great !
As you advised, copying the "Channel strip Settings" at /Library/Application Support/Logic/ and pasting it to the .bundle did the trick. Thanks Again !
2- At " /Library/Application Support/Logic/ " on the main drive, in addition to the "Channel Strip Settings" folder, there are 7 other folders ( Alchemy samples, EXS Factory Samples, Plug-in Settings, Project Template, Sampler instruments, Samples and Ultrabeat Samples).
Did you do anything with those folders ? (The whole 8 folders are 73,18 Go large on my main disk and I wonder If I may delete them or not and if they migrated to LP 12).
3- - Before copying/pasting "Channel strip Settings" to .bundle, as you mentioned it in one of your answers, after creating a software instrument track and choosing Sampler (Multi-Sample), I could indeed find the legacy .exs such as Liverpool Bass.
So, you are right: .exs files were not lost although I couldn't find them, as I used to, in the Libray.
Indeed a programing issue: I own Logic Pro since 2009 and this is the very first time that I have any "issue" with it, have to deeply look in to tons of folders, copy/paste etc. And I must say that I wouldn't have been able alone to fix it without your help.
4- Just for information:
After Logic 12 first installation, 6days ago , whole new "Sounds library" downloaded, installed and updated, the .bundle was 94,27 Go large.
After yesterday re installation, everything downloaded/installed/updated again, it was... only 92,94 Go large !
Main difference coming from "Patches" content (and "Projects" = Normal as I deleted some):
6459 elements for 1,05 Go in "Patches" 6 days ago. vs 6459 elements for 663,2 Mo in "Patches" Yesterday: All files there in both cases, but with quite often different size (See an exemple screenshot for basses and piano).
Isn't it "strange" ?
Anyway, I used the .bundle saved after 1st installation and after pasting in to it "Channel strip settings", it is finally 94,35 Go large.
Thank you so much !
