Who said it doesn’t make sense? It doesn’t make sense in Renoise, but it makes sense in general or let’s say if you’re about to do certain ways of composing. It looks like you’re not familiar with the history of DAWs. You need to know that piano rolls were “invented” in the 19th century, but the first piano roll DAW called Cubase was released by german company Steinberg in 1989 on Atari ST, but you also needed hardware to be able to get any sound out of it. In contrary to that, the first real tracker SoundTracker was released by german programmer Karsten Obarski in 1986 on Amiga. As you can see trackers are older than piano roll DAWs that we know today. And I’m an early tracker user who started in 1991 on SoundTracker. So when I first tried to use a piano roll in 1994 in Cubase on Atari ST, I already experienced the joy of quick and easy editing within a tracker for years. In contrary to that editing in Cubase was an inconvenient mouse clicking orgy that lets me turn away pretty quick. I hated working that way and I still do. For someone like you who got used to piano rolls from the beginning of ones “career” and never experienced trackers, it might not be comprehensible. But if you’re used to trackers, switching to a piano roll is like switching from BMW to Fiat.
You’re not familiar with my statements, are you? If you’ve followed the forum, you should know that I don’t have problems at all with someone using a piano roll or talking about it. But of course it’s pretty annoying if someone’s ALWAYS screaming for a piano roll in Renoise, just like some certain persons did for years in this tracker forum that’s dedicated to Renoise.
