Yeah I had some issues with the notation to. But reviews off DJTT have shown its on par with Mixed in Key’s detection method….showing equal success rates. The plus side to this notation, and I’m loving this by the way, is that I can now keylock my tunes and use the “key” adjust MUCH more accurately. It was virtually useless before bc I relied on the Camalot method. The +/- 1.00 – 12.00 key adjust measurements weren’t tranferable to Camalot notation (at least not for me….couldn’t get my head round it)….but with Traktors new key analysis it’s as simple as adding and subtracting. I may be wrong….but I immediatly tried it on afew tunes and it worked by my ears. Like I said it may’ve been sheer luck….but my outlook is positive so far. : )
