Long story short, far more keys are compatible in most cases and a maximum transposition of -/+ 2 sounds way better than exactly matching the keys of two tracks when the pitch shift is out of this range (e.g. +/- 4).
Older versions of Djay had an option to ignore Major / Minor, but this is gone too (at least, I can’t seem to find it anymore). A preference for Fuzzy Key Mixing instead of forcing an exact match would be awesome.
@Kpod21 and if you want to know more, check out this article by Digital DJ Tips. I could be wrong, but I’m pretty sure they came up with the idea and name Fuzzy Key Mixing:
Thanks so much both of you, this is awesome! Can’t wait to give it a try. Was struggling a bit using Mixed in Key trying to find enough songs that were compatible (I have a fairly small library) - this is a game/changer.
I suppose one issue would be that a strong vocal track might sound strange in a different key?
You’re welcome. Yeah you definitely want to be careful with vocal tracks; especially ones that are very popular and easily recognized. With tracks like this, I would recommend not changing the key of the vocal track and instead us Key Match to change the key of the other track that you want to mix with it.
