It would distract me from being in the moment and improvisation. So I never have notes with me. One thing that helps in that regard is standardizing things a bit. For example, when i look at that photo, you could also always set stab on track 1, bass/synth always on track 2 etc. With of course some freedom (multipurpose tracks for instance). I guess those notes are for digitone and it’s the one instrument where this is a bit more difficult to structure. But still.
Looking at a piece of paper, reading it, processing it, thinking about the things to do, maybe look again… It distracts from the actual performance and flow. YMMV of course
