Reply to Mapping Suggestions

hey ive been using dmb_00's vestax spin mapping and mixing internally however recently i purchased a ddm 4000 and have been mixing externally so now the line faders and the eq faders are somewhat useless so i was looking for suggestions on what useful functions i can map these faders to. i was believeing about using the line faders for a sweep build up on each deck. but yeah id like to hear some suggestions of what you guys would do thanks.
