Is there a list of CC# for the Axe III… I can change presets and scenes by selecting the Preset with PC then the scenes are just 0 to 7. how do I select for example Scene 1, pitch change bank B.? Scene 1, pitch change bank C etc..
No, you can assign CCs freely to any function as you need them. I keep a spreadsheet. I made a whole video series on YouTube for working with the Axe Fx III and Behringer FCB1010 MIDI pedal, so I needed to keep organized.
So to answer the second half, what I do is this. The example song is Undone by Weezer:
1) Send PC #1 - this takes me to the preset; it defaults to scene 2 (dirt).
2) Send CC #34, value 0 - this takes me to scene 1 (clean)
3) Send CC #36, value 127 - this turns on my Pitch Block
4) Send CC #38, value 59 - this tunes the Virtual Capo down to down 1/2 step. This is accomplished, as mentioned above, by the CC controlling the External Controller, which is assigned as a modifier in the Pitch Block's Shift parameter.
Now, I'm on a clean scene, downtuned 1/2 step.
What you could do is (assuming your pitch block is already on), is replace step 4 with:
4) Send CC #?? (whatever you assigned to the pitch block's channel function) with a value of 0 for Channel A. Then, when you need to switch pitches, send CC #?? (the same value as before) with value 1 for Channel B, etc.
