The device you are describing is the desirable, non existent successor to the CC121 that Steinberg should make!
The next most attractive thing like it I’ve been tracking is the Nektar Panorama CS12. I haven’t bought one yet but I might quite soon… Interesting development from Nektar... CC121 part II.?
I’m using the Korg Keystage controller keyboard and it works nicely as my DAW controller when I’m not using my CC121. Help - trying to use Korg Keystage as a Midi Controller - #47 by AlanP
