@twilliability yess, do it! It’s really fun.
I love my Midi Fighter twister (in the video). Before that, I was getting by perfectly fine with an akai controller, which is also a lot cheaper where I am.
imo for generative art things, the more dials the better (setting values! Cycling through enums!), and I usually use a couple pads for reseting the scene and such. (The midi fighter’s dials can be pressed as buttons.)
