Can anyone confirm for me that the 100 can record both to SD and DAW via USB simultaneously?  In other words like a back-up 2 track recording?
 
I haven't jumped but am still toying with the possibility of purchasing one of these.  Like others, I just feel Roland fell short of fulfilling the potential of this unit. e.g. ADAT, multi-track recording to SD, ease of multi-track file playback with multiple output routing options, etc.
 
Thanks!

no, it cannot be done but you can record 2 tracks separately to SD.

Haha - only took a week for an answer :-).  I was just going to answer myself but still haven't had the time to investigate.  I did buy one - couldn't pass it up at the Sam Ash price!

Thanks Andrew - that's a bummer.  Roland just really fell short of what they could have done with this unit.  Still look forward to some good use out of it!
