Novation have created mappings for Traktor Pro and Traktor Scratch which will be available to download from the Novation website to allow Dicer to be used to control cue points and loops.
Hot Cue, Loop Roll and Auto Loop Modes control Traktor Scratch, but not in the same way that they control Serato. You will find that the default User Mode buttons edit the size and location of the loops, and master volume control.
These User Mode 1/2 buttons can all be assigned in Traktor with it's MIDI learn function.
A full explanation of the mappings will be included in the download.
