Just a quick check, the track isn’t loaded to the deck is it? Engine DJ can’t analyse a track that is loaded to the player as it’s in use. Eject that and give it another go and see if that helps.
As for not having a waveform, that is a little strange. I would do a few checks that may (or may not) help but we can run though those. By using the reanalyse option, it will give the track the once over a second time but this time a more thorough scan.
- Is the USB device of good quality with good read/write speeds? Some older or cheaper ones aren’t the quickest and can’t be read fast enough by the players.
- Have you migrated from an Engine 1.X version to a 2.X version? There could be something strange in that upgrade process. You can close Engine DJ and delete just the Database2 folder in your Music > Engine Library and when it opens it will migrate the library to a V2 database again. Back this up first though so you can pop it back if there is any problems.
- Export the playlists to the USB storage device again after reanalysing in Engine DJ so the freshly analysed track is on a clean stick.
- I like to check my ID3 tags too. I strip any gunk out of them and convert any with umlaut or accent characters in the track titles as this causes problems in Engine DJ too.
Maybe @TJohnson can help with this as I know he’s helped with similar issues over here: Audio files crashing the system
