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.

I'm not an expert but I'll do what I can. =)


As for the Sampler Instruments folder, those .exs files are simply the files that you find when you create a software instrument track and use Sampler as your software for that track.


Open LP12 and create a software instrument track and choose Sampler (Multi-Sample) in the Instrument Slot on the track channel in your inspector. See screenshot.



Then open the Sampler. Do you see Liverpool Bass as in the screenshot below? If so, your .exs files are fine.



What I have in my Library/Application Support/Logic/Sampler Instruments folder:



My .bundle/Samples/z_Legacy/Bass folder which holds .aif files



And .bundle/Plug-In Settings/Sampler/z_Legacy/Bass folder



And .bundle/Channel Strip Settings/Instrument/03 Bass/02 Electric Bass folder and the .cst file, which is what you will see in the Library in LP12.



When I copied over the Channel Strip Settings folder into the .bundle file, that's when I started to see it in my Library.



I also copied over all of my old .patch files into the Patches folder that showed up in my Library



I hope this helps. If it is a programming bug then I hope it is fixed soon but after decades of computer use, it may be months, years, or never. But this workaround works for me.

I have been in contact with one of Apple Support's Logic Pro experts.


Apparently, this is a feature, not a bug! He said all the previous sounds are incorporated in LP12, just not necessarily under the previous known names.


Apple's Logic Pro technical expert offered two possibilities to get back "old" sounds:

1) Install a TimeMachine backup to LP11 and use this version... (hardly a solution), or

2) If a certain previous sound is required in a new project in LP12, then open the old project which contains the sound and bounce that required track into any new project. Repeat for each and every sound required, one by one...


He advised NOT to delete the Library/Application Support/Logic folder so as to maintain compatibility with the old track sounds that you might wish to recall.


To be honest, I find this all very disappointing, not particularly helpful and definitely very un-customer-friendly. But until enough people complain via the feedback form, nothing will change...

If you right-click on Logic Pro Library.bundle, wherever you put it, you'll find that the .exs files found in the Library/Application Support/Logic/Sampler Instruments folder have been relocated to different folders in the .bundle file. File structure has completely changed.


For example, you'll find Liverpool Bass.exs now in Logic Pro Library.bundle/Plug-In Settings/Sampler/z_Legacy/Bass. Why LP is not reading these files is a programmer thing and I don't know how to rectify that.


In doing a huge search, I've discovered that within the LP12 app Contents/Resources folder, 3 folders have been removed that were previously in LP11 Contents/Resources;


  • AppleLoopsIndex (which is now located in the new LPL.bundle Apple Loops folder and the extensions have been changed from .loopdata to .caf, thus no replacing missing loops with old files.)
  • Patches (now found restructured in the LPL.bundle, however missing quite a few .patch files from LP11 Contents. Note that these files found in the .bundle, can also be found again in the LP12 app Contents/Resources/UniversalPatches which is new) I'm coming back to this later.
  • Sampler Instruments (everything in this folder has been relocated, from what I've seen so far, into the .bundle/Plug-In Settings/Sampler folder)


I've also noticed that any folder beginning with "z_" is not being recognized. Going to do an experiment here in a sec.


I have been successful of moving .patch files into the .bundle and they work! Just a workaround for the necessary patches.


Here's what I did:


  1. Created a folder named LP12, moved the new app into the folder. (I zipped and copied to another folder on an ext drive just in case.)
  2. Using Time Machine, I restored LP11 back to Applications. I never opened the app. (I had to use this method since I didn't properly backup the LP 11 app as I should have.)
  3. Right-clicking the LP 11 app, I opened Show Package Contents.
  4. Copied over the entire contents (2.49GB) to its own folder on an external drive for backup.
  5. Moved the LP11 to the Trash and placed the LP12 back into the Applications folder and deleted the LP12 folder.
  6. Right-click Logic Pro Library.bundle and Show Package Contents. Went to Patches/Audio/Effects/Reverb
  7. New Finder window and went to my backed up LP11 Contents/Resources/Patches/Audio/Effects/Reverb and copied over Darker Tone Large Garage.patch and pasted into the Reverb folder in the .bundle
  8. Opened LP12, went to the folder and viola! it was there and it worked.


Of course, it would take a long time to go through all of the missing patches. I would rather Apple take care of what's not fixed but this is a workaround if you're on a time crunch.


I'll let you know what happens on further experimentation.

Jan 31, 2026 7:03 PM in response to Elfedelazik

OK! I think I found something. Here's what I did:


  • Right-click or Control-click on Logic Pro Library.bundle and choose Show Package Contents
  • In a separate Finder window, go to Library/Application Support/Logic and choose your Channel Strip Settings folder which should hold all your old settings from LP11.



  • Copy the entire Channel Strip Settings folder into the .bundle file



  • Legacy folder for Logic now appears in the Library and works for me.



Will sort through missing .patch files and place them in the appropriate folders as well.


It's not perfect and I have no idea how to do the GB legacy yet but if I come across it, I'll let you know. =)


Good luck everyone!

Yeah, this is the part you're really not going to like. What you're possibly missing are the .patch files that didn't copy over. =)


If you refer to this:

"

  • Right-click Logic Pro Library.bundle and Show Package Contents. Went to Patches/Audio/Effects/Reverb
  • New Finder window and went to my backed up LP11 Contents/Resources/Patches/Audio/Effects/Reverb and copied over Darker Tone Large Garage.patch and pasted into the Reverb folder in the .bundle
  • Opened LP12, went to the folder and viola! it was there and it worked.

That's exactly what I did. I opened two Finder windows, one for .bundle file and the other for the LP11 Patches folder, did a search for ".patch", and scrolled through and copied over the ones that are missing. It took me a better part of a day to complete. Over 6K .patch files. Lucky for me I'm retired and had the time.


I'm sure someone out there may have a much faster and better solution using Terminal but I don't know how to do that. You might find an answer on Reddit or StackOverflow.

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 !

I've managed to find some instruments "hidden" in Logic Pro 12:




::: FOUND INSTRUMENTS :::

• Neverending Riser = In Logic Pro and create a new MIDI - Software Instrument track, and then in the Logic Pro Inspector between the ”MIDI FX” and ”Audio FX” buttons, click on the Instrument button and select Synthesizer - Alchemy - Stereo. Then, click on the green Alchemy button and under the Default Preset dropdown, choose Legacy - Sound Effects - Neverending Riser. Done!


• Antarctic Sun = In Logic Pro Inspector between the ”MIDI FX” and ”Audio FX” buttons, click on the Instrument button and select Synthesizer - Alchemy - Stereo. Then, click on the green Alchemy button and under the Default Preset dropdown, choose Legacy - Keyboard - Antarctic Sun. Done!


• Old Robot Factory = In Logic Pro Inspector between the ”MIDI FX” and ”Audio FX” buttons, click on the Instrument button and select Synthesizer - Alchemy - Stereo. Then, click on the green Alchemy button and under the Default Preset dropdown, choose Legacy - Sound Effects - Old Robot Factory. Done!


• Massive Bells = Go into Logic Pro and create a new MIDI - Software Instrument track, and then in the Inspector between the ”MIDI FX” and ”Audio FX” buttons, click on the Instrument button and select Sampler - Sampler (Multi-Sample) - Stereo. Then, click on the green Sampler button and under the Manual dropdown (preset dropdown), choose Legacy - Textures - Drones - Massive Bells. Done!




::: STILL MISSING :::

• Acoustic Guitar Harmonics

• Piano and String Ensemble

• Pizzicato Ensemble

• Church Door Organ

• Space Keys

• Rock Harpsichord

• Almost Harpsichord


Any Logic Pro wizard who can tell me where these old ones are located in Logic Pro 12?


Feb 17, 2026 12:38 PM in response to dsparks66

Okay, I'm whining! Last week when I opened Logic Pro, I realized that my "Legacy" Instrument sounds were no longer where I was used to finding them. I am mostly creating MIDI Backing Tracks for classic rock and have found these files to meet my needs. After searching around, I decided to call Apple Support. The tech guy was super helpful and said he'd gotten several calls on this topic. As it turned out, Version 12.0.1 had been released less than an hour prior to my call. With the tech's guidance, I updated to 12.0.1 and Voila!....NOTHING! Whatever bugs that were fixed did not include addressing my problem. At that point, we ditched 12.0.1 and retrieved 11.2 using Time Machine (first time I have ever needed it!). Everything was back in place the way I like it.


But wait! I paid a good amount of money for this software and as time goes on, I want the support that is part of the deal. If there are problems in the future with 11.2, I want to take advantage of Apple's follow up to correct things. and while I am grateful for the detailed procedure in the above post by dsparks66 (thank you!), I switched to Apple from Windows 20+ years ago, I did so in large part because I don’t want to be bothered with diving into the recesses of various software programs to figure out a fix that shouldn't need fixing! And for the most part, that has come to pass.  But this is very “un-Apple like”! Now I’m old and spoiled and I just want the **** thing to work.  Rather than spending my time fiddling around and getting frustrated, how about Apple putting things back in a simple process that seemed to work? 

I have no idea how to express this directly to Apple.  If anyone has an idea about that, maybe you can post it.  


I suppose that if yet another update isn't added to address our concerns in the next several weeks, I'll follow the wonderful assistance of dsparks66 and update this manually. But I shouldn't have to. Agreed?

"NOK for"Sampler instruments" : lots of .exs missing (exemple with Electronic drum kit) in the LP 12 Sampler legacy library (see screenshot)"

Here is where I find those .exs files in my .bundle:


"NOK for "Samples-> Quick sampler" ( Can't find, in LP 12, any of the 64 .Audio AIFF located in the Quick sampler folder"

Here is where I find my .aif files in the .bundle:


"NOK for Ultrabeat Samples: Some sounds missing in LP12 (see screenshot)"

This one stumps me. I have the same issue. What I have discovered is that the missing sounds relate to the sample file extensions. The ones that have copied over and appear correctly in Ultrabeats, have both the .pst files and .aif files in their respective places. However, the ones missing have no .pst and have .ubs files instead of .aif files. Possibly no longer supported? It's the same with Apple Loops using .caf files and no longer using .loopdata files. Though I haven't tested to see if the .loopdata or .ubs files would work.



From the previous Library/Application Support/Logic folder, Adept Machine copied over correctly.


However, any sounds using .ubs, such as Afuche, have not copied.


I'll have to do some more digging and see what's going on. I hope this helps if anything to know why these particular sounds are different. The more you know...=)


In the end, this is a flaw on Apple's part and I hope they come out with a fix soon.

By way of update, I got a lot of my missing patches and instruments back using the method outlined by dsparks66. Updating the various packs accomplished nothing for me that I can see.


I got the rest of my patches back by copying them from an older version of Logic Pro 10. I had to compare the lists for the various instruments between versions, mark the ones that were missing in LP12, Airdrop them from my laptop to my desktop, then drag them into the proper folders within the LP12 bundle. It took a couple hours. When I tried this method by Airdropping entire folders (clean, crunch, distorted, etc.) my desktop system repeatedly crashed. I have no idea why. When I Airdropped files only, not folders, everything was fine.


I'm not happy about the wasted time and aggravation involved in this, but at least I got the sounds back. I will be very leery of future updates.
