Yes, you’ll need a laptop to write the scripts. Or, I guess, a phone or iPad - though I’ve not tried this. Norns is just a url away if you’re on the same WiFi network.
To be honest, I’m mainly in it for mlr which is a looper script. Give me a piano, a mic and mlr and tell me that’s all I’ll have for the rest of my days and I’d be utterly content. Elated! So depending on what you’re after you might not need to mess around with the scripts. That said - if, for example, you want mlr to always overdub by default - just edit the script! Hurrah!
I remember being at university when those first videos on Vimeo came out showing off the ‘monome’ and mlr all those years ago - it always seemed so out of reach! An impossible goal - to own such a thing! I’m so happy after all these years to have a grid sat on my piano next to my Norns. It feels like I’ve closed a loop.
