I found out how the ODESI keyboard didn't have black keys. Only white keys. Why? But on Captain Plugins, there are black keys, which are normal keyboards. Why is their MIDI Piano Roll different? Thank you very much for telling me.
I think you are probably using the Scale View option. In that case, if you are on a scale that only has white keys, it will only show you the white keys on the keyboard.
You can always change the view to Normal View and you also have an option for Folded View which will show you only the notes being played at the grid.
Let me know if it helps :)
