Strange. I record two tracks into the R-44, and when I connect to a mac, I see a nice little folder with two wav files. When I go four tracks, all I see is one wav file. Yet from within the R-44 I can still independantly adjust the level of each track, so I know the data is there somewhere. Roland has no support. Nothing in the manual. Can't even find an answer online. Surely someone else has had this problem, and it's something so totally obvious, I'll look like I shaved off half my moustache, right?
