Traktor Pro 4 deutsche Anleitung? Gibts es die?
I don't think so. At least I have never seen an up to date German one.
But you can use the online one and let the browser translate for you: https://www.native-instruments.com/ni-tech-manuals/traktor-pro-manual/en/welcome-to-traktor
But if you find an older German manual for Traktor 3, you can use that, as very little changed.
