A shortcut to active all override modes for everything would be cool when you really want to mess up your beat and see what comes out of it. I do it manually (lots of button pressing) quite often and just go crazy with the faders and knobs and sometimes really cool things come out of it that I would never have done purposely.
It’s a nice way to come up with parts of the song when inspiration for where to go next is lacking.
Together with a “save state as new pattern” feature it would be dope. Even though you can achieve the same thing by just copying the pattern first and mess with that one.
