It's definitely not the most advanced way to save or archive patches. I have thought about doing it similar as the factory patches have been organised. Column of bass, column of lead ... or having a "project of bass" sounds, "project of lead" sounds and get them into projects of picked patches for this or that situation. I think, patch-tags will only be available in MCC. But I haven't used the MCC very much, just to understand whether it works and how ...
Also the option to save out sequences independently from patches and play a patch with different sequences has also not found a place in my workflow yet.
At the moment I am happy enough to explore the MB, which I have since three weeks only, but I am continuosly taking notes in the back of my mind, how I could integrate it best to my workflow.
