As I've gathered from the Tascam site and these forums there are new mixer profiles available which allow better control with Cubase/Nuendo.
You'll be able to use all the 24 faders.
But it's good that you do your research and you should even test it in the store.
The most people are bothered that this controller doesn't have any lcd-scribble strips.
Below €1000 there aren't much options, above this you'll have the Mackie Control (around €1200), which isn't that bad, but you'll have to check the feel of the panners for yourself and see if you would actually use it in a reallife situation and we've had a lot of faders crapping out. But as I've read on the forum, the integration with Cubase and Nuendo is quite good and it supports 'flip' mode which allows the aux sends or the panners to go to the faders, this would be workable if you'd need to automate them. This is something which doesn't work in PT and thus makes it less usefull for me.
Then there's the Motormix, which is around €1800, which I can't comment on. Built quality seems allright. But in some way it's a bit focused on PT too much if you look at their website. http://www.cmlabs.net/motormix.html
And there's also the Radikal Technologies Sac2.2 which isn't bad. I tried it and liked its built quality and functionality but keep in mind that I tried it with PT and only for a very short time. All DAW's are supported as well. I thought it's also around €1800. http://www.radikaltechnologies.com/P...sac-2_2_0.html
You should also keep in mind that a lot of these controllers can use the HUI protocol which was created by Mackie, but they can also work as generic MIDI controller for which you can make your own profiles in your software, but offcourse it's much more easy if there are good mixer profiles available, which by now should be for most of them.
Maybe the Mackie Control is your best bet after all. But go to the store and try them out.
