unfortunately the manual isnt available in German, which is my language. I cannot find, whether it is possible to define zones (whole Keyboard), so that it should be possible to play multiple instruments (layers) which are adressed by different midi channels. My idea was , to have one slider for each zone (volume control), so I would be able to mix the layers by volume controls. If this is possible with the keylab?, so I need help how to realize it by midi control center. Thanks for hints and help!
