How do you mean?
Synchronizing recording and playback so you have that many more tracks?
Synchronizing the DMT-8 to computer-based audio or midi playback?
Connecting the DMT-8 to the computer to use it as a mastering deck?
Connecting the DMT-8 to the computer to use it to back up projects?
Connecting the DMT-8 to the computer to use the DMT-8 as a "front end" (preamps, EQ, etc) for the computer's sound cards?
The DMT-8 is very limited compared to current standalone recorders but I think it can do all of these things. Not completely certain, as I haven't tried them all with mine. What specifically did you have in mind--I might be able to be more help with more details.
