Hi, I'm using MIXO to update VirtualDJ lib from Rekordbox. I did several complete backups from RekordBox to VirtualDJ - and I loose de prepared stems - thats a shame.
I did partial update - using only changed playlists and I noticed something even worse: Mixo is mixing '/' and '' of windows. On VirtualDJ side, the database is not aware of '' and writes duplicates when updating index. At the end I had plenty of duplicates that make the library confused and may trigger twice the stem analysis. I took half a day to write a script in Python to resolve all the mess that makes Mixo - I did it but it was very very touchy - with a lots of backup - restroe. Now I think I have a tool to resolve to possible problems but still a little bit anxious using Mixo. If you want to have a look to my script you can ask I can send it to your developers - to get an eye on it
