"I've been using harmonic mixing for many years, but I had to find the keys with a keyboard. Mixed In Key is as good, in less time. Magic!"

"I live by Mixed In Key. I use it religiously and key everything so I know what key to jam on a piano on top of any song! It's part of my performance."

"Since I play with 4 decks simultaneously, I find Mixed In Key very useful especially when I play melodic and vocal tracks. Layering different drums, melodic riffs and vocals, the outcome is seamless."

"I'm a big fan of Mixed In Key. Keep up the good work!"

Armin is teaching DJs how to use Mixed In Key in his official MasterClass.
