Corrupt (?) Concert Crashes Mainstage On Load

I worked on a pretty massive Mainstage concert yesterday, about 300 patch changes total. Everything was running smoothly and I finished my worked, saved, and restarted the computer. After restart, I went to open the file. It goes through the process of loading all the patches, then gets to the end of the progress bar and says "loading concert", at which point Mainstage crashes. I am devastated, as the most recent backup is about a week old and I need a way to either fix this file or salvage the data within it.

 

Note that I haven't gotten the "your concert is corrupt" message—it just crashes every time I try to load it, so I can't access the concert.

 

I've searched around the web and tried various things (deleting plists, moving the "Nodes" folder to a new concert, etc.) But nothing has worked thus far. Can anyone help? Here's the crash log:

Hi

 

I had pretty much the same problem.

What I did is opening the main stage with one of the templates.Saved the template as new file. Close it and then opened the problematic file and it opened correctly.

 

I can't really explain why this happen, but it worked for me few times

 

hope it helps

Just tried your suggestion, but no dice.

 

Can anyone who knows what the crash report is saying tell me why it's crashing in the first place?

After some creative exploration into importing and exporting patches, I have discovered a way to recover the contents of a corrupt concert, as long as you still have the concert file.

 

Here's what you do:

 

1. Navigate to your corrupt Mainstage concert file (by default, these are stored in User/Music/MainStage). Right click your concert and select "Show Package Contents".

2. There will be a bunch of files ending in .plistZ, a "Nodes" folder, and a .layout file. Open the "Nodes" folder.

3. You should see a) your master channel strip files (something like 001 Reverb.cst, 002 Output 1-2.cst, etc.), b) files called "base.plistZ", "mappings.plistZ", and "uidata.plistZ", and c) a folder for every set in the show, containing folders for every patch in that set. As it turns out, the file structure of this "Nodes" folder is almost identical to the structure of an exported "Set" from MainStage. We are going to recreate a .patch file manually, then import it into a fresh Mainstage concert.

4. Create a new folder and name it whatever you want. Probably the title of your concert.

5. Copy the contents of the "Nodes" folder to your new folder and delete the files "mappings.plistZ" and "uidata.plistZ" from the top directory. Do NOT delete these files where they appear within your individual set and patch folders.

6. In the new folder, rename "base.plistZ" to "nodes.plistZ".

7. Now open Text Editor and create a file with the contents "/Applications/MainStage.app" and nothing else. Save this to your new folder with the name ".LSOverride". Finder should ask if you want to create a hidden file or something. Accept.

8. NOW. The top-level or your new folder should contain ".LSOverride" (hidden), "nodes.plistZ", and folders of every set in your show, containing folders of every patch in those sets. Rename the new folder to end with ".patch". Finder will warn you about showing a folder as a single file. Accept.

9. You should now have a patch file that you are able to import into a clean Mainstage concert. Open Mainstage, create a new concert, then press Command+I. (Alternatively, in Edit mode, find your "Actions" menu (the little gear with the arrow) at the top of your Patch List. Toggle the menu and select "Load Patch / Set"). Select your newly created .patch file from the finder drop-down and click Import. Mainstage should now load all the patches and mappings from your corrupt concert!

10. Rejoice, for balance has been restored to the universe once again.

 

Optional: Remember the .layout file we saw in the concert's package contents? You can import that, too. Just go to Layout mode and select "Import Layout" from its little gear menu.

 

I'm pretty sure you can also recover your master channel strips by moving them to the proper location in the new concert file. I haven't tested this, though.

 

I hope this saves some folks from having to recreate their concerts that corrupt for bizarre reasons. Oh, and one final tip: BACK UP YOUR CONCERTS!

One way to avoid this - besides having backups - is to run MainStage in 64-bit mode. I've seen quite a few issues that were triggered by working in 32-bit mode, running out of memory and saving corrupt data.

BTW: This very creative solution is really a last effort, because it will break certain mappings within the patch.

Unfortunately, my concert was running in 64-bit mode and this still happened. But yes, a good point for others to note!

It might be that the concert was already damaged by the out of memory situation. You might want to contact Apple with this issue: http://www.apple.com/feedback/mainstage.html

what patterncity described should be a sticky somewhere here. indeed the cst's are embedded in the file contents - nice work!

 

here's the thing that I don't get...

 

I always save my progress as I progress forward when building a large concert... save as concert.1, concert.2 concert.3... why? because if concert.3 blows up (and this has certainly happened since the early days of MainStage), I can always go back to the previous "save point".

 

am I the only guy who does this?

 

I do the same with everything, Logic projects, Word documents, whatever... Yes, some products are kind enough to save "versions" for us, but... I'd prefer to define my own savepoints/fallback points.

 

and in IMHO, 64-bit mode (provided you have the memory installed to support going beyond 3GB) - may lead to less corruptions-that-show-up-when-loading instances, but not all cases. I've seen a 3rd party plug crash, and corrupt the MainStage concert file too...

 

all the more more reason why I have the save as... routine that I do...

 

anyway, nice sleuth work patterncity!

 

300 patches in a concert file??? wow...how many songs is that??? respect...

THANK YOU! This worked perfectly for me!
