What a shame the 01x doesn't do windows 7. I was completely gutted and now use mine as a digital mixing desk. I think Mlan was great apart from the rubbish support from yam obviously.
Anyway, I went with an a500 pro controller keyboard and do think it works very well. Motorised faders it doesn't have but it has.....
Sliders control track volumes.
It remembers which windows you are in and allocates the controls appropriately.
Easy to set up controls for all softsynth and effects, which it remembers forever. (Most of the time).
Cheap.
Good on space.
Drum pads are ok.
Lots of rotary controllers and sliders.
Transport control.
For me the 01x was great as it allowed hardware mixing and cubase/sonar software controls all from the one box.
I think I would wait until some usb3 stuff comes out. That is the future IMHO. No need for FireWire anymore and usb3 is v fast so you should be able to get an 01x type of setup which includes the audio interface built in and will run very quickly and handle anything you throw at it.
I think those vs700 are a total rip off tbh. The a series keyboards on the other hand are cheap and give everything the 01x did in terms of a controller, but with easier setup using act, which I find very easy to use and setup.
I may get a fully fledged controller surface soon, but will wait until we see usb3 devices which are probably going to be very good value for money.
