it provides me with different key (which is correct) (I triple-checked my key mappings and it is correct).
And this is not the one and only song which behaves like that - I started to verify every single song analyzed by Lexicon to check if the BPM + GRID + Key matches the reality, cuz I cannot trust it. And thats not time-saving at all
The beatgrid analyzer is not always right so manual adjustments are sometimes necessary. However, Serato does not properly support these multiple beatgrid markers so it’s not really possible to get a perfect grid there
BPM is the same as the beatgrid analyzer, so not always right.
Key is a different analyzer but it’s quality is not where I want it to be yet, it’s alright but not great.
You can let any DJ app analyze the beatgrid and key though, and import just that information into Lexicon. Traktor is great at beatgrids. See this guide
