I think this is a pretty nice way of organizing presets that you need for a specific project. If I understood everything right, the patches won't get saved on the Rev2 itself, right?
I have lots of sounds on my Rev2 that I never play live in my band, because I created them for some home projects... with this workflow I could free up memory for all my band stuff.... hm... perhaps I will give this a try.
I didn't care about Editors for the Rev2 very much... but used in this way... and just for "viewing" the settings I make on the unit itself... since I like Ableton Live very much and are planning to buy the Suite edition soon, perhaps the codeKnobs software is a great addition...
