Importing saved sessions brings back nothing. Patterns, timing, voicing are all gone after hours of work. …but looking at the xml file it looks like the data is still there, but Scaler is not reading its own backup files. I didn’t have this problem in earlier versions. Please fix.
What is you computer and OS?
What DAW were you using?
Can you post the xml file so we can take a look at it?
If you saved your DAW session Scaler should still have the original session.
I am seeing something similar and lost work as well. It might be related to this: Scaler 2.5 overwriting full sessions - Support / Bug Reports - Scaler Plugin - Community Forum
If so, Dev team have their eyes on it.
I’m trying to reproduce consistently but cannot yet. Will post if I can.
