I've also only recently gotten into NS with plans to use it live, but I've only barely scratched the surface of what it can do.
Don't forget about the 4 CV ins on the Nerdseq, which can be mapped to pretty much anything, including generating euclidean patterns on the fly (it used to require the trigger expander, but I think you can do it in a regular track as of the most recent firmware, haven't tested it yet). The Nerdseq isn't the most immediate or "playable" sequencer out of the box and requires some setting up, however, once you have some stuff going, the CV ins can be invaluable to mess with your patterns and evolve them on the fly. I'd consider a joystick or something like the Lapsus Os with several CV slider offsets to pair it with the NS.
