Good question Stam. Personally the only (main) thing I see that it has over the WK is the 16 tracks for recording. Again the sequencer on the GW has also been in question as well.

Andym, could you go more in depth for us on the sequencer on the GW-7. I remember reading the manual some time ago and not seeing anything for basic editing for the tracks after the recording process such as level, pan, ect....
