Can’t open Audio 8 DJ settings to take off software lock

From https://www.native-instruments.com/forum/threads/cant-open-audio-8-dj-settings-to-take-off-software-lock.145258/#post-961092:

i just figured out that you can hold in the “input mode” when you attach the USB to unlock the “software lock”.

just an old trick i’ve learned over the years working with different devices. Hope it will help anyone in the same situation..
