After the latest update, I exported to an empty engine DJ library and now every song is broken and the waveform displays some red rectangle at the start of the tracks.

I deleted my old library again and repeated the process. My files are all local on my D drive, my engine DJ library is on C. Issue persists.

It seems like the tempo information is lost, because the track is now playing infinitly slow

Hi there,

I don't think that logic changed in the last release. Are all the tracks analysed in MIXO? Also, what happens if you analyse the waveform in Engine DJ?

I'm not able to replicate this at all. Here's a test:

So did you delete the m.db first, them export from MIXO?

Where did you import your music from into MIXO?

Analysing Waveform in EngineDJ works fine. I did delete the m.db first. I also deleted it once, launched Engine DJ to recreate an empty one, and then exported from Mixo again. The music in Mixo was first from Rekordbox, and then to fix some issues I once exported it to Serato and then imported again. The latest beatgrid was edited by me in Mixo.

But it also does not work for beatgrids I did not edit in Mixo at all.

I also tested exporting a fresh engine dj USB, same issue with the red bar at the front (now on my Prime 4) and the song being stretched to 57 hours.

Interesting. Quite a lot going on there, I wonder if some incorrect data has been imported, like the duration. Can you check in MIXO to see if all the columns look correct?

You could try importing from Rekordbox again, then export to a fresh DB but let MIXO create it.

It looks right in Mixo, and in the last version exporting to Engine DJ had worked, I am pretty sure. I also tested the export from two different devices.

Whats the recommended way to clean up the library and data. Analyse songs in Rekordbox first, or Serato, or directly in Mixo?

I think it's personal preference. MIXO will always need to analyse your songs to export artwork and waveforms etc but the DJ software is more accurate when it comes to beatgrids.
