I bought Serum through Splice. I just got Ableton 11.
Issue: I'll bring a file from Ableton 10 in, work on it, and when I re-open it after saving to an Ableton 11 file, it inits all the presets. Also posting in the Ableton forums..
Anyone else experiencing this? Or have a solve?
Most likely you have multiple versions of Serum installed and Live is selecting an old version on song reload.
I would recommend to check your VST2 Custom Folder and delete Serum_x64.dll from any and all locations in that folder.
Rescan and verify Serum is no longer available.
Then run the update installer to that location.
