Pete,

From your response earlier, it seems you are doing your editing on a hardware DAW? (the DP). Have you tried a software DAW? Editing tracks for something like this is WAY easier in a software DAW. You owe it to yourself to try one out (if you have not). You can try Reaper for 60 days (I believe). I think there may be a free version of Studio One and one for $20... they would get you started (I may have misinterpreted your earlier statement)...
