my picture is taken from my vci100 (mk 1). the jogg has two different (hardwired) modes (two encoder-notes, lets call dem x and y). I can switch between scratch/notesX and seek/notesY with this button. I dont need no shift (or in other words a modifier)
i would guess the mkII hast such a button too!?
if you want to make you own mapping in traktor. u need to know what traktor can do, how u can implement it ( = how the controller-manager works) and then where, which midi-notes come in through your controller.
I set up a modifier- number 8 (modifiers 1 and 2 are used. i thought I’d start from the other end)
set left shift to make mod 8 go to 1 then off (HOLD)
set right shift to make mod 8 go to 2 then off (HOLD)
set left wheel to seek position - only when mod 8 is 1 (ie when holding left shift)
set right wheel to seek position - only when mod 8 is 2 (ie when holding right shift)
Holding shift and wheel makes fast forward.
–I could extend this to deck C D with mod 8 set to 3 and 4–
