"Bend your will to understand midi, then make midi bend to your will!" This has been my motto lol... though I am not winning every battle.
I wanted to share something that I think is worth sharing:
Before trying to assign G MAJ 2 presets to your GCP, save the Factory presets to your user bank. Then, go to your midi button on the GMAJ2 and change your setting from Factory to User. Ah, now you can assign your customized user presets to your GCP. If this order of process is not followed, your edited changes on the Factory bank will not save your changes (edits) at all. This drove me crazy for a while but I won that battle.

Bend your will to learn midi, then you can bend midi to your will...
