I highly doubt its anything to do with the file considering that trying again with ‘dont touch my beatgrids’ off fixed it
Again this was a new mp3 so the beatgrid should have been added either way. The behavior should have been the same with or without that checkbox.
BTW i dont know if you saw my comment in this thread that the slightly off BPM issue is still around: 120 BPM Tracks in EngineDJ Despite Correctly Identified Sample Rate - #26 by jack
Both these things should be added to your tests. I feel like you are relying on AI to tell you what is happening and the AI is hallucinating answers here. I’m guessing thats how you ended up with the (incorrect) theory about engindj desktop messing up sample rate before. You need some tests and to eliminate all those try/catch and fall-back blocks that AI adds. Those try/catch blocks hide your problems and the AI will hallucinate guesses about what is happening
