This thread should be elsewhere. But, Yes, the Axe FX II responds to CC 34 for scenes. You then need to send the value.
The Axe III allows the user to assign the scene CC number. I noticed that recently, the scene cc assignment appears in 2 places in the midi menu, and that they can be set to different settings. I'm not sure why.
On the LF pedal, you can make IA slots for 8 scenes, and then create a LF PAGE, so that your IA slots for Scenes appear on the pedal in the right button location you prefer.
I suggest, that if you do set up 8 IA slots for scenes, that you place them in the same group (see the GLOBAL MIDI tab in the editor), so that they are mutually exclusive and act like presets. In other words - only 1 scene should be active at a time. On your pedalboard, if you step on the button for scene 1 and it lights up as active, but then you step on the button for scene 2, so it lights up and is active, the button for scene one should not still be active - only 1 scene can be active at a time, therefore, only one of your IA slots for scenes should be displaying as active on your pedalboard.
