abyss, you have to update your nunedo 2 to 2.2 (update downloadable from the net) otherwise you will have 3 duplicates of tracks 1-8, not 24 independent tracks. i tested this before plunking down $2 grand on nuendo 3 to see if it were really superior to cubase (as far as just audio was concerned). thankfully, i was able to save big big bucks seeing that cubase is not a crippleware version of nuendo on the audio application side. so, the difference is this: with nuendo 2.2 touching the faders will not automatically arm the tracks, with cubase sx3 the tracks are automatically armed as soon as you touch the fader (as is the case with nuendo 3 i gather), but this is something that needs to be resolved within the DAW software, not with the US2400.
there are buttons labeled "bank +" and "bank -". the way these buttons work is kind of weird because pressing them doesn't seem to shift the faders to the next group of tracks. whatever tracks are missing are simply added so that the last track is in the 24th fader. i guess a simple work around is to add tracks evenly in multiples of 24, even if you have to leave them empty. i think some people have resolved this but i have yet to sit down and get familiar with both cubase and the US2400.
the thing with the 2400 is that you have to do a lot of reasearch if you wanna customize it completely. download all the update files of the 2400, all release notes, all recent manuals etc. a lot of people complain that tascam cannot help them with their questions. there's a forum for 2400 users who are familiar with its quirks in different DAW apps, etc. and they are quite accomodating. i read up on a lot of posts and complaints before purchasing my 2400 to see if i will be able to make it work on my terms.

1. it's a cost effective way to have 24 automated faders
2. it does the job quite simply (rewind forward play record attenuate eq pan undo arm tracks mute solo etc)
3. the jogwheel is SO useful
4. it looks cool
cons':
1. i haven't figured out how to control plugins
2. unlike the mackie, the faders are not electronically labeled (which IS a hassle) so you might have to find a way to label it manually (there's space for that though)
3. not well documented, can be difficult to install
4. i haven't figured out how to make the faders work in the RECORD mixer. it works for playback though. again, im hoping this is something that can be resolved in cubase or the RME Total Mix at least.
i think that's about it. i hope to find the time to sit down once and for all and try to make it work perfectly in my setup. maybe next week or so. till then, good luck on your research.
