Feature:
**** One problem I've had with the Ultralite is that it's drivers won't work with over 3 Gig of RAM. I have 4, but I can only use three because of this "known issue" (according to MOTU support, although they mean, "known to us, but we're not telling anyone about it until after they buy one"). Not wanting to waste memory, I recently bought a Focusrite Saffire, because their drivers don't care how much memory you use. But I ended up returning it, because the sound just couldn't match the Ultralite - the Saffire sounded very thin in comparison. Another area the Saffire didn't measure up in was the headphone level. I'm a loud singer and I need plenty of level to track vocals, and I would've had to buy a headphone amp to be able to work with the Saffire. The Ultralite's are way loud enough.

Quality:
I've had some issues, but none with build quality. It's solid. **** I will say if you're using Vista, turn off the Aero interface. I was having a lot of pop/hiss/click noise issues as a result of the MOTU drivers conflicting with Vista and the graphics card. Once I turned off Aero, no problems.

Value:
Worth the going price on sound quality alone.

Desirability:
Not the prettiest interface, or the best aesthetic design.

Sound:
The sound of this unit is impressive, especially at this price point. I've gotten impressive, near commercial quality vocal tracks running a Studio Projects C1 through a Studio Projects VTB1 into this unit. Playback of mixes and other audio also sounds great. It's accuracy has allowed me to produce better mixes.

Ease of Use:
It's true, the knobs are too close together. Once you get over that, it's a non-issue. The MOTU is pretty easy to dial in.

Support:
MOTU support leaves a lot to be desired. Expect to wait 48 hours for a response, and don't expect it to be too overly helpful when you get it. With regard to my memory issue, their response was basically, "Yeah, we knew about it all along. Guess you'll have to wait and hope for a driver update." Thanks, MOTU.

Overall:
I'm still looking for an interface that will match the sound quality of the MOTU, but will allow me to use all of my memory and have better drivers and support. Eventually I might have to move up to RME or something. But until then, I gotta stick with this interface for its sound and ignore its ugly side.

Feature:
see "Sound." lots of inputs, tiny box.

Quality:
amazingly robust for its weight & profile. don't know where the "brittle knob" complaint comes from. suggestion: don't try to hang your guitar on the knobs, maybe?

Value:
for the features, & for those who can afford a mac shop, it's perfect. probably not recommended for the windows world. you'll have problems, and there are other, less elegant solutions for you. don't buy one, i'd say, only to complain later that it's a "mac thing" or too expensive. instead, use google to find "windows firewire audio interface." or you might consider why so many happy, successful folks never have to wrestle with drivers & security patches...

Desirability:
certainly a sexy bit of gear. so tiny & capable. "all you brought is THAT?!"

Sound:
didn't use "10" because there may be better mic pre's out there. but this is 9.5...

Ease of Use:
the interface is far from intuitive and requires a bit of twiddling, but i haven't found a sound i want that i couldn't create. admittedly, this is not for noobs. experience with similar is required, but if you grok the "page & value" stuff, it's not a challenge. interfaces flawlessly with logic & coreaudio, but that's no surprise, since everything motu has been meant for mac for 25 years. probably a kludge with kludgy systems.

Support:
motu support has always been knowledgeable and accessible, although they can be impatient with dumb questions. hell, so am i.

Overall:
for its purpose, part of a studio i can fly around without blowing carry-on weight limits, i expect to have this for a long time.

Feature:
Seems to be as featured as the others I've owned in the past.

Quality:
This, I give the worst rating. My volume knob broke off within days of owning it...it was weakened before I got it, I suppose. I've owned other equipment with similar knobs and it took years before they weakened. I don't think these cheap plastic posts with long jutting out knobs are good designs. They need to think of something better, especially for equipment designed to take out on the scene.

Value:
Kinda expensive for what you're really getting. I would shop around for similar products and compare the features.

Sound:
Sounds okay. I have problems with it bubbling and blipping when I switch from one app to the next. It pops and flicks when it turns off in a major way. The quality seems okay when its working.

Ease of Use:
The mapping is okay but the software they give with the thing is stupid.

Feature:
too many to mention. but i do got to mention it comes with DAW software, but it only works with MAC'S.

Quality:
built like a TANK. metal cover. love it.

Value:
with it's many ins and outs and 2 mic's ins, well worth it.

Sound:
between good and great.

Ease of Use:
simple.

Support:
no need yet.

Overall:
very well built. portable. easy to set up with each sequencer. if you carry it, your laptop must have a regular big size firewire in, otherwise you will have to use the power supply that it comes with.

Ease of Use:
Error message: No MOTU hardware has been detected! This thing was a typical POSh made for Mac headache. Their driver for my 6 pin fire wire card is not compatible with it. Not to mention that they don

Feature:
-Build-in Mixer: It does include a build in mixer but not very usefull. Better get a small mixer, unless you are very tight in space. More as a gadget, cause you can't control any OUTPUT except the master. Only the input is controllable. So you can't even have a mix of 2 Output with a one input. -Driver/software: On PC side, i found them limited feature on the driver. Even with the software the output are not controllable. Also all the volume control from software using WDM doesn't work. Also WDM doesn't have access to Output individually except if you put the driver in a special mode not recommand by motu for performance. -Sample Rate: At this price I was expecting a full range up to 96K. but only support 44K, 48K, 88.2K, 96K. So if for any reason you have audio file with different sample rate, it won't be support. -Power supply: Bad design, I hate those Wallplug, take 3 ACplug! -Hot pluging: When connecting the device, it lock the PC for 10 Secondes. So not fully Hot plugging compare to other device. -Firewire: Been using a firewire card TI with FW HDDrive on one controller and Ultralite on other. Had some pop noise, sometime application hang or HD was very slow. Using the ultralite only, fix the issue.

Quality:
Case is very well design and solid. All connectors are professional and gold plate. Except for the Rack ears, are in kind of plastic. As for suggestion, I will add 2 handlebare on each side to protect the button and face and also been a half-rack is not very

Value:
I found this unit a little price, I paid $699 Canadian, and was expecting more from the Driber/Software and mixer build-in. Reading a lot before buying it from all the Magazine comment and internet saying it had all kind of feature..hummmm.

Desirability:
I putting a five, cause it nice and do his job. But I found it not very versatile, and price so unfortunatly I send it back. And will try another Audio Interface.

Sound:
Mic pres sound good and general sound from the output is very good.

Ease of Use:
Ease of use was in general easy, but I think there still improvement to be made on control. I won't use the control for LIVE application except for the master output control. Will have been good if with the Master output control button we were able to control output of different output but pushing the button and select the output. But again there is not control on the output witht the mixer and the software. Only master control the 2 output.

Support:
Call them cause the serial number was unreable, the ink didn't stick to the label. There send me another SN withtout any problem. Also contact them for all the other issues mention above.

Overall:
In Conclusion, I was expecting a Top of line sound card firewire for PC/Laptop, versatile for recording, live application VST, and support by DJ software and all other Windows applications. Unfortunatly, it maybe do it jobs well for what been design, Recording! But I think there a lot of space for improvement on the Driver side for feature, compatibily and stability on PC side (didn't test the MAC). If you are looking for excellent sound quality versus general feature/Compatibility, this seem to be a good unit except it's a little pricey.

Desirability:
Those guys that rated this badly are obviously rookie producers. Take a few classes, or in your case....maybe just stop trying to produce your own music. Some people should not even tempt to be a producer/sound engineer. MOTU is one of the best companies for cross-platform interfaces !!!
