It is a midi interface on USB port, 1U.
8 in / 8 out MIDI box perfect to control my pace and EA-1 directly into Live 4.
I could have an interface with less of the saying but I am for the future.
It is connected to a USB 2.0 hub on my laptop.

UTILIZATION

-No problem for drivers and installation (thank you Motu).
Stabilit-flawless, I use it with Live 4 and I never had any problem until now (no loss of the interface in use, with an obligation to either reboot pourqu'elle nouveux DTECT, as sometimes happens on some models of competition).

OVERALL OPINION

I've had a month and I'm glad trs. It's simple and did what we asked. I regret one thing though, there is no switch and is the Get You Started ds usb port on which it is connected is powered ... damage.
Price level relative quality, I find trs COMPTITE seen the quality of manufacture (it's solid), even if it does not patch merger and that it can not function without a PC.

It's two balls of coquetry, but I find that with the 828mk2, has a lovely set!
