After buying pretty much every midi controller possible. I ended up buy this from phase one. The whole design of the unit uses Tracktor 2 to best way possible way, The clever placement of the filers and sample banks makes the unit a dream to use. I can't recommend this midi controller enough. 5 stars to Native and Phase One
