I think familiarity has something to do with it, but your own screenshot is definitely way less cluttered than the radium one, which is showing A LOT. It's not just the waveforms, which I get, but also what seem to be multiple layers-within-layers of sequences or something like that. To be fair, I've seen other screenshots of radium that look a lot more sane. This one might just be arranged to show off all the things that radium has going on.
Oh yeah, your Radium screenshot is hella complicated - but the surprising thing to me is how much it makes sense for me, even though the last time I touched a tracker was back around 1998.
