I would like to know

How can lexicon change almost all the bpm of my songs when exported in engine to put them at 120??
If I add to that, the pieces that it moves randomly, those that it deletes, this program does not work with engine!!
it will have made me waste a lot of time, energy, and money!!

Is the BPM in Lexicon correct?
Try using Reload Tags on all your files in Lexicon, because it could be that the samplerate of your files is wrong and that can cause Engine to think your tracks have a wrong BPM like 120.
After reloading tags, do a Full Sync to Engine.

the problem with full syncr is that i have to reanalyze the songs with engine, if i don’t do so, the analysis is done when i load the song

just a playlist sync will work too for that

I’m sorry, but it doesn’t work
every time I load a new track, my prime 4 analyzes it
