I'm looking to do some very basic recording. I think the choice is between the UX1 and the black box but I am certainly open to some suggestions for PC recording in the $200 range. It appears that both devices come with ableton lite. I'd like to do the following things, please tell me if either device can do it and what the best choice would be

-Import a song off a CD and play it back for me to hear while I record guitar tracks over it
-Record a guitar track and then layer it with additional guitar/vocal tracks
