Hi there, I already tried this one, the MIDIMate eX
It works but… normally the 2.8 MPC firmware was supposed to get the USB midi to work but I dunno. All these connections between wifi, bluetooth, midi DIN, minijack, USB is really a bit a mess. I don’t have girl troubles like the Violent femmes song but cables troubles. 
I’ll take a break from there for today and get back with new fresh mind soon.
Take care.
