Hi,
You will need to export the wav files across to your PC and then inport them into cubase. Easily done via the USB option - and is reasonably quick to do.
Just check the sample rate etc in Cubase match that of the 2488.
You can have syncing issues if one of the wav files was recorded half way through the song, eg a gtr solo. as the wav file will be shorter in length and you will need to line it up correctly in cubase. I have just added a section of silence so all the wav files exported start at 00:00:00 - makes life easier.
