I am also experiencing the same, and it’s utterly irritating.
I have MCX8000 set to off in the settings, and yet it still performs MCX8000 related jobs every time I start the software.
Also, every time I select a different drive it “checks all the files” for the drive. It’s so slow and irritating.
I’m not sure this is not in the way of using the program. Of course it’s not done in the UI thread and does not block the user from doing other actions, but it clogs access to the files in that drive, and it’s simply unnecessary.
We can consider further improving this if there are roadblocks to use that come up.
Well, you’d better improve this software as I’m sorry to say that unfortunately is way behind Rekordbox, or the library management in Traktor or Serato. Both in features (cannot search by label, cannot even display label, difficulties navigating the library, no sync) and performance (super slow, super disk intense).
I’m really looking forward seeing Engine Prime improved.
