The New Rane MP2015 rotary digital mixer has excellent build quality, top-notch sound, and a cool way to mix music using knobs instead of faders. The Rane MP2015 has four channels and an additional channel that can be used to link other channels together for easier manipulation. The Internal dual-USB soundcard that is present on the MP2015 is capable of running Traktor DVS timecode over these channels as well as recording a mix in high-quality audio. The Rane MP2015 has an isolator section at the top which also allows for some cool EQ effects on the fly. Check out the new Rane video showing the use of the new Isolator found on the MP2015.
