Hi Philipp,
Thank you for your message.
Cubasis LE comes bundled with a wide range of audio devices, which can be used to unlock the app from demo mode.
All supported devices are listed on our dedicated Cubasis LE website.
In your case it seems that the Zoom F6 device is not yet supported.
Since it’s up to the hardware device manufacturer decision what devices to bundle with our app, I recommend to get in touch with Zoom regarding the topic.
Hope that helps!
Best,
Lars
