When I try to MIDI learn on the joystick it only lets me choose the X axis. No matter what I do it won't choose the Y axis. And then, even when I manually add the joystick Y axis, it won't let me assign both axis.
I managed to get it to work by learning the X axis on MIDI ch2, turning off Learn, then manually changing the MIDI channel to 1.
Then I turned Learn back on and manually added the joystick Y axis, and it took the Y axis CC# from my X/Y pad, again on MIDI ch2.
Then I again turned off Learn and manually changed the X axis back to MIDI ch2.
Now it works, but only kind of as expected. I have to rotate the pad 45 degrees counter clockwise for it to match the screen.
