Hi Ars nova,
Thanks for your message.
So far we did not experience any issues in that area.
Here are some sugesstions, that hopefully help to solve the issue:
- Reset the external keyboard to its default settings
- Close all apps, followed by an iPad restart
- Enable MIDI Input Only for Armed Track on/off setting (located in Setup/MIDI)
If all of this fails, it might be worth to give Cubasis a re-install.
Please make sure, to create a proper backup of all your data up-front.
Best,
Lars
