Logic Pro 12: Missing Legacy/Ancient sounds

Hello everyone,

Sorry for my poor english.

I upgraded to logic pro 12 from last upgraded 11 version two days ago and

downloaded / installed all what wasn't from the new sounds library ( = a 94,27 Go Logic Pro Library.bundle exported to an external ssd).

In "Library" or hitting Y, before upgrading to V12, I could find some old stuff inside of Legacy/Ancient folder for each categories ( Such as Liverpool bass in "bass", Male rapper voice in "vocal" for instance etc.). Lots of this legacy and ancient stuff has become favorites.. but I'm unable to find it in V12.

Is it gone with V12 for the first time ?!? Is there a way to recover all this legacy/ancient material ?

Thank you a lot in advance !

Go to the Sound Library (Logic Pro menu). Click on "Manage Packs". You should be able to add the legacy Logic 10 sounds back. Mine were missing, also. I did this, it's all back. Be sure to update anything needing it, also.

No acknowledgement yet from Apple. At least as far as I know.

What you experience gives an answer to this question : " Maybe a brand new fresh installation fixes the issues ?" and the answer sounds like "No !".

What problem(s) do you have ?

The main one for me was the legacy content not available / showing up in LP12 library ( hitting Y): Many guitare/ Bass/vocals stuff there became favorite in time and Pffft.. they were gone in LP12, while still there in /Library/Application support/Logic.

Thanks to dsparks66, things are back to normal for this point.

What’s really weird is that the legacy sounds still show up in Garage Band. It seems like some users don’t have this issue with Logic hiding the legacy instruments. But I’ve got an up to date iOS and I’ve tried deleting and re-installing the legacy packs, refreshing the library etc.

Can you give a specific instrument or loop that you're referring to within Studio Horns or Strings? Are you seeing these in the LP12's Library/Loop Library or are they missing there too?

I ask because when I do a search for Studio Horns within the bundle, I have five separate folders and a .cst file within my Channel Strip Settings folder

I can show you what I have in my .bundle folders as far as Studio Horns and see if this is what you see in yours.

Logic Pro Library.bundle/Patches/Intrument/Brass & Woodwind/Studio Horns (contains .patch files)

Logic Pro Library.bundle/Samples/Brass/Studio Horns (contains .caf files)

Logic Pro Library.bundle/Apple Loops/Studio Horns (contains .caf files)

Logic Pro Library.bundle/Plug-in Settings/Sampler/z_internal/Studio Horns (contains .exs files)

Logic Pro Library.bundle/Plug-in Settings/Studio Horns (contains .pst files)

Logic Pro Library.bundle/Channel Strip Settings/Instrument/08 Pop Horns/Studio Horns.cst

I hope this helps. =)

Good luck!

Thanks again for your fix. Yes, I've done the library search for 'wide wide wah' and nothing came up. Which is weird, because when I open a project that was recorded with that patch it's still there, still with that name and still works in LP 12. Very odd.

The good news for me is that I have LP 10 on my old laptop which can no longer accept upgrades. So all the original patches are in there and I can copy them over if a better solution doesn't present itself.

Seriously, thanks for helping troubleshoot this. Apple should be doing this work, not users. This is the first 'upgrade' of Logic that has ever caused me a problem. Disappointing.

Yeah, 12.2 seems to contain some major corrections. Most sounds are back in the library, but unfortunately not all. And definitely non of those guitars that @dsparks66 showed us in an earlier screen shot.

Ahh... Got it!

I'm mostly working with midi tracks though, so I suppose that I must convert each track to audio to reach those sounds. On the other hand it looks like most of them can be generated (more or less) with the amp plugin, even though it may take some more tweaking.

Concerning the software instruments... Can you for example find "Big Electric Lead" in your library? It's a good old guitar favourite from Garageband that's been around for ages, but not anymore (at least not in my environment).

One other observation... Before LP 12 my Sound Library was + 90 GB. Now it's only +40 GB. I don't believe that more than half of the content has been removed, but could there be some more effective compressions that Apple has applied?

This didn't work for me. I must be missing something. Mine weren't missing when I upgraded and on install, I updated all packs. Everything is downloaded and updated. I even deleted the "compatibility" packs, quit, restarted the machine, reinstalled the packs, quit, restarted the machine, and still nothing. Sound Library shows the legacy packs installed but they're just not showing in the Library for some reason.

I know they're using a new file system via the .bundle in the Music folder so I don't know how this is actually supposed to work. I feel that I'm missing like an "activate" the installed pack or something.

Not to mention, I used to have some 30k+ loops in Apple Loops before, now there's less than 28k.

Still no legacy/ancient in the "Library" (Y shortcut) !

Thank you for your answer.

The userFolder > Music is empty.

I found the legacy content on my Mac drive at "/Library/Application Support/Logic/" and in "Sample instruments" (While the new "Sounds library" has been moved to an external ssd after Logic was upgraded to V12). Il looks like this legacy content hasn't been packed/transfered in to the new "Sounds library" V12 file (Logic Pro Library.bundle).

Same thing here.

What's the overvall size of your "Logic Pro Sound library" after installing/upgrading all available packs from the new "SoundsLibrary" 's window ?

Mine shows 94.5 GB, in Info: 94,504,809,211 bytes (88.84 GB on disk)

Great work/search !

I have to forget about time machine: on my mac 8 months old mac mini M4 pro, sequoia last version the 8 months old Kingston SSD NV3 1 To inside of its 8 months old ICY BOX IB-1816M-C31, especially purchased for time machine, only works if it remains plugged to the mac mini ! I saved my system 7 months ago and carefully store the ssd in a safe place. When I wanted to use it to restore logic 11, it didn't show up anymore on the desktop although still visible using disk utility but getting error messages tryingto fix the issue.

I had to format it again = Backup lost.

I did a new time machine back up 3 days ago: All good until I unplugged the ssd 2 days later. Same problem then.

So.. I formated the ssd again, new TM back up and I keep plugged to the mac until I know more about this issue.

What's strange is that I have another external ssd for the mac mini (Crucial X9 Portable 1 To) where are saved the new Sounds library, some datas and old projects: I don't have any problem if it's connected/disconnected fro m the mac.

To come back to the legacy library, apple loops etc.. issues, what's weird is that it looks like some users don't have the problem while other face it.

I hope that the Apple logic team sometimes have a look at this forum and fixes what has obviously to be fixed in a near future !

Thanks a lot for your help !

The mystery is getting deeper:

On 2nd screenshot's left side: What I can find on the mac drive at Library/Application Support/Logic ((Not the same arborescence than you ! And the legacy stuff that I'm looking for such as Liverpool bass etc is located in to the "Sampler instruments" folder containing .exs files (1st screenshot). This libray = 73,18 Go for the 8 folders)

On the 2ndt screenshot's right side: Logic Pro Library.bundle 's content (on the external ssd, where is now Logic pro sounds libray located): Here again, not the same arborescence than yours ! And I can't find any .exs file in any of its folders.

So I didn't copy/paste anything from Library/Application Support/Logic to Logic Pro Library.bundle 's package content :)

Thank you very much again for your answer(s), your in depth explanations and all the time spent to help !!

I will look closer at it tomorrow when I get up (and report).

Right now, I'm almost 100% sure that we have the same Library/Application Support/Logic/Sampler Instruments content.

This afternoon, I finally uninstalled and reinstalled Logic pro 12 and this time didn't change the " Logic Pro Library.bundle" 's default location on the main drive. I'll do it when the whole new "Sound library" will have been downloaded and updated (Still in progress right now).

Two maybe "dumb" questions:

If you create an audio "Guitar / line" track, not a Midi instrument one, do you also see the legacy content in the library window ?
When you copied the "channel strip folder" from Library/Application Support/Logic to the .bundle file( after right clicking it to show its content and paste in to it) , do you mean that you copied/pasted the 5 "channel strip folder" sub folders (Bus, Instruments,Master,Output,Tack) or only the Instruments subfolder ?

Once again, thank you very very much for your help and all the time spent !! Really very nice from you and much appreciated ! You're a king :)

Excellent news! You're very welcome. I'm so glad I could help. =)

As to your question;

"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)."

No, I did not do anything with those folders. According to this: About the Logic Pro and MainStage sound library on Mac – Apple Support (UK) "The cloning operation requires no extra storage space. You don't have to delete the old sound library files to optimize storage space on your Mac." Of course, I don't see how this works.

If you want to experiment, you could move one of those folders to another location. Then open up LP and see if those particular assets disappear. If not, I would believe they would be safe to remove. I would suggest creating a new folder, placing all the folders inside and zipping/compressing them. Then, if you have room on your external drive, save a copy somewhere since you mentioned issues with your Time Machine. Then delete the above folders. This way if things go sideways, you have a backup.

"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'?"

I ran into this as well. The newer versions are larger and after putting both in LP library, I noticed there were tiny differences in the channel settings but no difference in sound. I, myself, just kept the newer versions.

Yep , I thought of this experiment and the 8 folders are saved for a try ( at least, the "Channel strip" folder should be "deletable" as it's been copied to the .bundle).

I'll tell you quickly about the test.

In my case, last install files (from yesterday) are smaller than those from 5/6 days ago 1st LP 12 installation/upgrade from 11. I didn't test the sounds and kept the biggest one haha.

btw, whether would it be from 5/6 days ago or yesterday, they're all related to a LP 12 upgrade or reinstall so - I might be wrong - to LP12.

I don't know why but messages here don't look ordered according to the moment when they have been posted, chronologically => A bit of a mess and hard to follow if you weren't part of the discussion.
