Hi,
I use SysEx Librarian, is user friendly, fast and free.
You can store multiple preset sets and recall it when needed.
(if you want you can also edit your stored preset banks directly in TextEdit, I used it to move single preset to different banks. Not very immediate and maybe a bit risky but it works…)
