Comments about Focusrite Scarlett 8i6 USB Audio Interface:
I purchased this unit to supplement my Firewire interface since my laptop didn't have firewire, and I wanted to try using ITB effects at live shows. The goal was to evaluate using it for "live" vocal effects and to play backing tracks from Reason at small gigs, as well as feed MIDI to the Yamaha for keyboard parts.
I was worried the latency would be too high, and that the USB might glitch out occasionally or be unstable, but it so far has been rock solid at ~6ms using the Asio4All driver on Windows 8. My CPU is an AMD A8-4500 in an ASUS laptop, and I'm using REASON as my DAW and effects host. So far I'm pleased to report there are no issues with compatibility or weirdness, and the only glitch I had was solved by disabling the wifi adapter when I'm running a show.
I'm using this as an "Insert" type effect on two vocal channels for compression, reverb, and the occasional telephone filter or other special effect, plus sending a mono backing track and a click track to the MixWiz. In this configuration it has been stable so far, and the ~6ms latency has been barely noticeable. As a precaution, I'm returning the Vocal feeds to two spare channels instead of a true "insert" on the mixer, so if the PC goes down it's easy to mute the return channels and unmute the originals, then go on with the show. It hasn't been a problem yet, but makes sense to have a backup plan when working with computers. Plus it avoids using the pre-amps on this unit, so I get a consistent interface for sound and levels setting on the mixer.
The best round-trip latency results were achieved using the Asio4All 2.1 driver, a sample rate of 88,100Hz, buffer size of 64 in Reason, and a "1ms" setting on the FocusRite control panel. Additionally, I disable my WIFI card and DVD drive just to be safe, since they seem to increase the odds of a glitch. The FocusRite driver seems to add about 1-2ms additional round-trip latency that the Asio4All driver doesn't add, but still gives respectable results in the 7-8ms range at 88.1kHz.
I have not really scrutinized the pre-amps or converters, since my application is just for live use. They sound good live, but in a demo recording were a bit noisier than my Profire 2626 rig. The Profire has really good pre-amps though, and this Scarlett 8i6 wasn't too far off. In practice it may not even be noticeable for home recordings.
The feature set is pretty decent. I wish FocusRite had a rackmount kit for this unit... It looks like it's designed for a 1/2 rack space but I couldn't find any kits to actually bolt it in. Instead I velcro'd it on top of another rack unit, and it stays put pretty well while being accessible enough to bypass or tweak on if anything goes wrong.

Takes a bit of time to set up the first time. Doesn't come with manual, you have to go online. Have to play with the latency settings a bit to get rid of poping.
Excellent.
Solid. Well made steel & aluminum box.
Good, especially considering it comes with Ableton Live 8 Lite (which is the main reason i got) $211 new.
Comments about Focusrite Scarlett 8i6 USB Audio Interface:
Initially I was worried I would have to send it back. Audio kept cutting out, and I would have to turn the unit on and off (by unplugging it--there's no switch). However, this seemed to be corrected when I installed the latest version of the control software (I think it's called Mixcontrol. I'm using a Mac btw). This loaded new firmware the next time I used it, and that seems to have fixed the problem entirely!
The mic preamps seem very nice so far--very quiet at full gain. I could stand another 6 dB or so on my condenser mic, but so far it hasn't been an issue.
Overall I can't believe the quality for the price. I think this product deserves top marks, assuming the new firmware continues to be as stable as it seems so far. I only wish it came in a different color!
