I've added my MIDI controller (Akai Professional LPK25) as an external device. When I press its keys, Studio One seems to pick up input based on the bottom-left (where it says "MIDI" and "Performance"). LPK25 shows up on the first drop-down of my track but not the second; this is different from the tutorial I'm watching (go to 4:53 to see his track). Finally, when I drag a keyboard from "Presence" onto the console, LPK25 on my track drop-down gets replaced with Presence and my MIDI doesn't control the keyboard that appears.
Does anyone know what my problem(s) might be? I really want to get started recording stuff!
