i would like my rane four work with traktor pro 3 any however its very hard to create mapping from scratch
It appears as if there are no ready made Rane Four mapping as of yet even though more people want it. I have seen that there are Traktor mapping files for Rane 72 & 74. So Rane have interest in Traktor mapping.
Maybe you will have better luck over at the Rane forum ?
