Feature:
Phantom power for 4 XLR inputs is the prime reason I bought mine; it's convenient to have this many inputs directly accessible. I actually prefer the MW10 to the 12 for this reason (12's inputs are on the back to make room for faders). I'd have liked a SPDIF output/input; I think a lot of people may want to use the mixer w/ at least one workstation synth, and having to use 1/4s for that is kinda lame. That'd be the single biggest addition Yamaha could make imo - not sure how much it would drive the cost up, but I'd have paid $50-75 more easily if it had been there.

Quality:
Solid construction, clear labeling.

Value:
I think it's an amazingly solid deal, and a sign of just how affordable electronic recording has become, that I can get Cubase LE, some additional effects/plugins, a 10-track mixer with 4 XLR/phantom ins, and a USB audio interface for $200. I'd recommend this to anyone, especially those just getting started. I have much pricier kit in my main studio - I bought this for my living room setup, which is basic - but I think I'll be utilizing it quite a bit.

Sound:
No hum, clean. I don't understand the one complaint that the output is too quiet; I'm not having that problem, and I like things loud.

Ease of Use:
Plug and play, although the ASIO driver is a separate download. They should probably emphasize that a bit more with a separate sheet in their documentation, but it's basically a no-brainer anyways.

Overall:
ASIO latency is def. acceptable but could be a little faster. They've already released one driver update that helped with this - hopefully it's the first of many. Besides that relatively small issue, the lack of SPDIF I/O is my main complaint. For the money, though, I think this is a fantastic alternative to buying an audio card and then a separate mixer, or going with a USB interface that's less convenient in terms of work surface.

Feature:
Could be better, but who can complain, i mean look at the price tags!

Quality:
There are some weaknesses or rather flimsey aspects of the board, but I am sure it would last through a few simplefallsor thumps.

Value:
It is a great deal for the capabilities it has and also amazingly fits into any budget!

Desirability:
It can either make or break the look of your setup just be careful positioning it. It can turn your budgeted studio into a workin wonder.

Sound:
Great, especially since the product is so inexpensive. It has a little sound weakness. However,this would be an ideal and great deal for someone on a budget that is creating a home studio!

Ease of Use:
This is a fairly easy product to create essentialosunds, and quaity music with.

Support:
The company is very hard to reach, but they seem to be understanding, sometimes stubborn though.

Overall:
Unless my studio was for a complete album/LP for sales. Which really the producers and record label will pay for.

Feature:
I know Yamaha gear stands up pretty well, and I only needed a few channels to mix some analog synth outputs. So I purchased this and immediately noticed (a) the recording levels out of this thing are really low - meaning the gain of the preamps is as low as it couod possibly be (b) there is distortion when you get the gain structure wrong (c) The manual is perfunctory, and the power supply is proprietary - so I can't substitute a stock wall wart when it fails. I'm going to put together a passive mixer and compare the spec. If I can keep the signal drop to 3dB or less on the passive mixer then the Yamaha mixer gets sent back to the company's R&D dept in Japan with an abusive letter. I spent $400 on this device and I expected a tad better from Yamaha. It works, but it ain't pretty.

Sound:
I can hear the noise floor on tracks recorded through it. The USB port chatter was audible on playback monitoring - and I think I'm going to have to work out if the sample rate and bits are correct between the PC (XP Pro / Pentium Dual Core) and the mixer.

Ease of Use:
Straight forward. Lif the gain to reasonable levels of amplification and wait for the distortion.

Overall:
If it was stolen I'd recoomend the thief for a Public Service medal.

Feature:
Includes everything you would need. If only it didn't have the fatal flaw I mentioned above.

Quality:
It feels well-built; it's Yamaha. Could probably go through a small war without breaking.

Value:
It's not a good value if it doesn't perform its duty as advertised.

Desirability:
I would want it if they fixed the USB output volume. I'm not running it through a hub or anything like that; it's running on a well-powered desktop that has never had problems with any other interface before. It's sad that no good budget USB mixer appears to exist, with the Alesis suffering from the Hum of Death.

Sound:
It sounds good for an inexpensive mixer. Good preamps and good sound quality. But the USB output is far too quiet, even after following the steps in the manual to overcome said problem. The gain required after recording to bring the sound up to a decent level is enough to cause distortion/aliasing in the original sound. I can't recommend this mixer based on this reason; I'll be returning mine shortly.

Ease of Use:
Easy enough for anyone who's ever used a mixer before. Even if you haven't, the controls are clearly labeled and the instruction manual is somewhat helpful.

Support:
The online support is shaky at best; information about the drivers is nearly non-existent.

Overall:
I'm returning it because it doesn't do what it's advertised to do adequately. That should say something.
