I don't agree, the problems were summed up by CS in another post:-
----------------------------------------------------------
Hi everyone,
After getting a copy of Cubase 6 I have noticed much of the same symptoms as everyone else:
*Cubase crashing when exiting (with AlphaTrack configured). It won't crash when AlphaTrack isn't on the device list.
*In Cubase (32-Bit mode) the AlphaTrack is listed on the device list but the controller will lock up after a minute or two
*In Cubase (64-Bit mode) the AlphaTrack isn't recognized in the device list at all
There were similar issues when Logic had their version (9.1.3?) that allowed for a 32/64 bit versions. I've forwarded this message on and hopefully this can be resolved soon.
I haven't yet seen this in Windows but I'll keep messing with it and see if I can reproduce your symptoms cuboquattro.
