If your .song is crashing or hung use this procedure to identify the issue.
Something in the “.song file” was incorrectly written to the computer. This can happen due to the environment of your computer changing while working on the song, or a misbehaving plugin.
A) FIRST IF YOU ARE STUCK WITH AUTO OPEN, OPENING THE BAD SONG?
If not go to the STEPS TO DEBUG SONG.
If you are stuck in a mode where you have turned on "open last song/project" you will have to edit the Studio One.settings first.
B) Go to your Settings Folder: via the Studio One Help Menu/Open Settings folder
On Windows Path = C:\Users\([u]Username[/u])\AppData\Roaming\PreSonus\Studio One 2
For Mac the Path = ~/Library/Application Support/PreSonus Software/Studio One 2
The File = Studio One.settings (open with text editor like Notepad and edit this section)
<Attribute id="Application.DocumentHandler.startupAction" value="1"
Change value="1" value=1 to to value=0;
C) This will turn off auto load the last song so you can open Studio One without a song. Save the change and open Studio One.
STEPS TO DEBUG SONG
- First make a copy of your song so you have it as a safety. Use the File Manager to go to your song directory and find Your_stuck_song.song and add _debug to it, so that you can disect it.
- Open Studio One
- Go to Options/Advanced/Services
- To start take an educated guess of what might be hanging up your song. (Did you start using a VST3? Did you start a video? Did you start using Melodyne? Did you just try out a new VST2 plugin?)
- Disable the service that might be related to why your song no longer opens.
- 4) Close Studio One and Re-open Studio One with the service off
- 5) Try to open your bad song.
Did it open?
If yes the issue is with the service you just turned off.
If no then you guess wrong. Repeat the process and turn the service that you turned off back on and disable another service off.
Repeat until you have isolated the services that is having the issue.
6) YOU NOW KNOW THE SERVICE BUT NOT THE PLUGIN
Use the flowchart below to turn off/disable or remove plugins etc that are associated with that service.
If you turned off VST3 then turn off half of your VST3 plugins to isolate the bad plugin. Repeat as needed.
If you turned off VST2 then turn off half of your VST2 plugins to isolate the bad plugin. Repeat as needed.
If you turned off ARA, then remove Melodyne from tracks. Repeat as needed.
Follow the procedure below and you will fix your problem.
It has saved me a few songs in the past so I hope it helps.
