I own both an Novation Launchpad S and a Launchkey 25. I would like to use both devices at the same time but am having trouble. I would ideally like to use they keys on the Launchkey for midi synth and knobs for adjusting devices as I go but found this to be a great stuggle. Attached is a screenshot of my preferences. As you can see both devices are listed but only one has control of the project.
