Help for creating a TouchOsc Layout for Axe FX II

[SynFactory]

I've recently downloaded TouchOsc for iPhone and I want to make a layout for the Axe FX II.
I'm not afraid to tweak and learn things, but I'm quite a noob regarding midi messages.
Let's say for example, I want to create a knob to control the "Amp type" in the "Amp 1 Block".
What kind of message I need to send to the Axe for controlling it?
Is there a list of commands available in the Axe II?
Thanks!
