Remove Patches from a concert that won't open quickly

If a concert loads very slowly, you can remove Patches from it in Finder before you open it.

1. In Finder, open your MainStage folder and find the concert.

2. Duplicate it first (right-click > Duplicate) so you have a backup.

3. Right-click the concert and choose Show Package Contents. Then right-click Concert.patch and choose Show Package Contents again.

4. Select the Patches you want to remove (the .patch and .cst files) and drag them out. If you've changed them from the originals in Patch Builder, move them to a folder inside your MainStage folder so you can add them back later.

5. Restart MainStage. If the concert was open, don't save it.
6. Reopen the concert. A "File Missing" warning is expected. Click OK, then save.

7. Add back only the Patches you need. The Go-to Sunday Keys Patches are in Patch Builder > Layered Worship Patches > 1. Go-to Sunday Keys Patches.

Trimming a Set? A Set is saved as a .patch file. Use Show Package Contents on the Set's .patch file and remove Patches the same way.
