I definitely practice a lot when I have a gig coming up! Also, like @tedthetrumpet, I try to set aside time to just play my set and not fiddle with functions. I was just re-reading an article from Sam Aaron and Simon Blackwell (Craft practices of language I think) and Sam has a nice reflection on this.
I also try to separate out phases between warm-ups (typing basic building blocks of my set and keyboard warmups), free experimentation, composition, and more concrete rehearsals.
