Interface 2 and USB-C (New Macbook models)

Hi everyone,

I would like to hear from Pioneer DJ official support personnel as well as from other users, about how Pioneer DJ mixers/interface and Rekordbox are performing over USB-C. Especially on the new macbook pro line up.

I currently use a Macbook Air Mid-2013 core i5 1.3GHz 8GB RAM, with Traktor Scratch Pro, and the timecode works like a charm on a Traktor Audio 6.

I also own a DJM-450 that came with a Rekordbox DJ and DVS licenses.

I'm strongly considering migrating to Rekordbox DVS, since the launch of the Interface 2. But also, the time has arrived for my old Macbook Air.

I would like to know:

1. Does anyone have tested the Rekordbox DVS with the new Macbook 12" and USB-C? Or the new Macbook Pro 13" w/o touch bar? How stable they are?
2. It's safely to play on a Macbook 12" with the interface/mixer connected through a USB-C Hub plus and additional midi controller (e.g., Novation Dicer)? Since this computer has only ONE usb-c port
3. By any chance, someone already tried to connect the Rekordbox Interface 2 on the new Macbook Pro with a USB-B to USB-C cable? Like the ones from Belkin: http://www.belkin.com/us/p/P-F2CU035/
4. Which is better: one USB-C port with a Hub (Macbook 12") or two USB-C ports (one exclusively for audio interface and the other one for charging + midi controller) like on the Macbook Pro 13"?

Thank you.
