Unlike pad controllers they are not currently customizable any further, but you can adjust both the CC numbers (or pitchbend) they generate as well as the MIDI channel and pointer snapback behavior here. XY controllers are mostly configured by options given on said 'MIDI Assignments' screen. The 'MIDI Assignments' preference leads to another screen that holds individual settings for each of them. The initial preference screen contains options that affect both halves. Setup options for XY and pad controllers are located at Setup / MIDI Utilities / XY Controllers & Launchpads.
