For each fader -- and in this case, you don't have 16, but many more, since I mean each channel-CC -- you'd need to have ONE supercontrol and one subcontrol in MIDI Designer. You could get some savings with Channel Changers but really... IN THE WAY you want to do it initially, that's not a use-case that's easy to handle. If the Kenton is bidirectional, the goal would be to amplify the role of MIDI Designer in your rig and have the Kenton merely be a "dumb" controller for MD. In that case, you should be able to use Global Presets and get your Kenton (and your real MIDI target) to respond. On the other hand, if you must keep your current setup with the Kenton as is, another product -- perhaps MidiFlow, though I don't know -- would be the ticket, probably. Thanks!
