I have just registered a Kontrol Z1 and these apps are available for download on Native Access.
There's no name provided and no indication of their purpose. If you know, I'd love to hear.
I already have Traktor Pro 2 software installed.
Thanks
The one at the right is the image of Traktor Pro 4.
There is a bug, for many months now, that Native Access shows apps without a title but it was always Kontakt 5 and Reaktor 5… I never see yours before!
I will report it, however, please ignore any no name app and do not install it. Installation will fail anyway.
