Komplete Kontrol 2.9.6 was the latest version in which it was still possible to drag loops and one-shots into a DAW. This feature is not available anymore in versions 3.0.0 and after that. Will this be fixed in future updates of Komplete Kontrol? It looks like this is a bug.
On their website it is mentioned that this is a feature of Komplete Kontrol. This page is also outdated when looking at the screenshots which are taken from a Komplete Kontrol version before 3.0.0.
