I dont see much zoom users (is that a bad sign?) out there, but I tried linking my dr5 to my zoomMRS1044cd and ran into a couple headaches. One is that the bass on the dr5 can go to 6 string and goes to low B where the zoom bass sound only goes to E.
An other question is hows the roland digistudio compared to the zoom?
