Hi @Marcus_Weichel,
Thanks for your message.
Cubasis allows to save own MIDI Learn presets.
Here is the link to the MIDI Learn chapter in the additional online version of the Cubasis in-app helps: Setup
In addition, please also check out our available MIDI Learn tutorial:
In regards to see an official Oxygen preset, you might get in touch with M-Audio to let them know about your wish. Of course, we’re at hand to have them equipped with a promo code for testing and development.
Hope that helps!
Stay safe
& best wishes,
Lars
