I wanted to use my DDJ-RX natively in Traktor
Hey there, DDJ-RX is natively designed for the rekordbox dj software but you can use it with Traktor Pro by enabling General MIDI mode and importing a third-party mapping file. You should be able to find mappings here: https://community.native-instruments.com/categories/mapping-traktor
And on other forums like this one for DJ Tech Tools: https://maps.djtechtools.com/mappings/6559
