Feature:
The Us-2400 didnt do what i expected and have software integration lack. I use Sonar 3 on a Pc, i knew after buying it that : 1- touch sensitive fader dont work, 2- the SEL button dont work at all, 3- cannot work on Eq, 3- the combination of F-KEY and SEL in order to put a track in Record mode dont work as well, 4- the Meter dont work as well, as Sonar do no support it, 5- the bank indicator do not work (remember 8 bank of 24 faders), so you might get lost after a while if working on big project... and so on, all the interesting extra feature they show work for many of them in Native mode. In order to use it in Sonar, you must put the unit in Mackie Control protocole emulation, loosing the most interesting feature. So what you got left? The fader, the pan and Aux send. Thats it, thats all. Deception... But it do the job if youre looking for a straightfoward 24 fader control surface. But you might want a little more features.

Quality:
Its a well built unit, and dont have the sensation of a cheap unit. The fader are great, silent when moving and most of all, it is Solid, like the entire unit.

Value:
for a 24 fader surface control, it's a bang for the buck. the quality is good for the price.

Sound:
no matter heres, its simply a control surface...!

Support:
didnt know

Overall:
depending on why you want this unit, inform you well before buying it. You might be pissed off. For myself, i've own this unit 4 day, then return it back to take a Mackie Control Surface, wich is really more integrated in software then the Tascam US-2400 can dream about. Read well all the info and manual available on the Tascam website, it might be a good unit for you, this time was not for me.

Feature:
Before upgrading my US-428 to a US-2400 I contacted Tascam Tech Support to make sure all features were mapped to Cubase SX3. I specifically asked about the channel strip function with 12 knobs for eq plus 6-8 aux sends. The assured me it all worked, so I made my purchase. It wasn't until after I got it all setup and upgraded to the latest version 1.20 that I found out they told me misinformation. I waited on hold again on my dime (they don't have a toll free number) then someome finally admitted it doesn't support channel strip, nor banking (i.e. to get to channels 25-48, etc.) in Cubase SX3. I was told to wait 3 weeks for the next release and it might work then. I waited a month and the release never came out. I contacted them via email and they never responded after 2 weeks, so I sent my message again, they finally responded (a month after my 1st message was sent) to let me know they don't have a release date for the fixes to Cubase SX3 mapping. Meanwhile I'm doing 40 track projects and mixing tracks 25-40 with a mouse and doing all my eq settings with a mouse. The faders feel like cheap plastic, but overall the funcationality that does work seems to work ok. Best of luck if you do purchase this item. It does not work as advertised and tech support is awful.
