Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
There is a hidden coolness here. This thing seems to have a PODxt DSP processor inside of it, seen as the effects are applied without asio/coreaudio latency.
From http://www.line6.com/toneport/overview.html:
"With Line 6’s exclusive ToneDirect™ monitoring, you get fully processed audio in real time while you track! Far better than recording through plug-ins, it avoids the latency from your recording program and operating system. ToneDirect also easily beats analog direct monitoring options that force you to record guitar without hearing the amp model and effects, or struggle to get an inspired vocal with no reverb! With GearBox software and TonePort hardware, it’s easy to get amazing sounding recordings every time inspiration hits."
That is pretty cool when you think of it. It's like having a DSP powered input FX frontend for your rig, similar to TC's Powercore. The catch is that the FX don't work in mixing, although in theory it should be possible to make somekind of insert vst/au shell.
Another way to look at it: this is very probably a PODxt on the inside, without the preset/programming interface, without MIDI, but with mic preamp(s) and stereo line inputs. You can probably hook up a simple laptop over USB just as a fancy POD UI, and not have to worry about CPU cycles at all with regard to your tone.
It might just have to get me one of these :-) At this price it's actually pretty crazy good.
Props also to the industrial design team; the UX2 looks especially good I think.
