I try to import from hard drive. But it imports the whole song as one playlist and not in subfolder. This would be a must feature. Sync hard drive folders in their prespective subfolders to playlists. If this couls happen the app would be number 1

It's on the list! I think we'll prioritise this:

Will be in the next release :)

Great! It will be sync or just import??

When you import a folder containing tracks from your hard drive, for example via drag/drop, it will create playlists using the folder name. It also includes folder nesting.

See example video attached.

Live in MIXO v2.14 :)

It works great!!! I imported and analyzed 43000 tracks! Also I tried to add one more track on real folders, I dragged them again the parent folder and analyzed only the new one that this is good. When adding new music to folders to sync with the existing library and analyze only the new ones.
One defect. I erased some folders and they are not erasing from library. Only grayed like no existent.
Also, I added a cue point and it is not writing at the mp3 file like in serato that you add cue point and its written on file metadata.
Keep up the good work!!

Thanks for the feedback! MIXO won't automatically delete tracks or playlists in MIXO if you delete them on your computer. They are totally separate.

Also, to write cue points to your tracks, you need to use Export/Track Tags. Or with Export/Serato just make sure the toggle is on for Update track Tags.
