Hi Sunshy,
It is possible to save and share your key commands preset via iTunes File Sharing.
This requires to connect your iOS device with the computer and iTunes.
Please follow this Apple article to learn how to find and use “File Sharing” in iTunes:
Cubase iC Pro’s key command presets appear in the “Cubase iC Pro Documents” folder.
It is possible to backup these files from there, or to paste/transfer existing presets to that folder.
Hope that helps, please let me know if it does…
Thanks,
Lars
