This is a very sensitive topic. I like some of the features of a piano roll but don’t really like using one.
My biggest fear is that Renoise dies and I am forced to use a piano roll or use the last version of renoise before it died. future kids telling me I’m so old for using renoise. Making fun of me.
There was some post a while back on how to implement something like a piano roll into a tracker. Basically creating colored blocks where the note starts and ends. There are some tools
like posted above. Maybe that is what you saw. There is hidden stuff in renoise. Very hidden things. I wouldn’t venture too far.
That’s a real problem with trackers : it looks like an excel document more than anything. But that’s the way it is.
It’s fully off topic, but let’s be honest : there’s no big names promoting it nor any really good videos/channels showing what are the benefits of using something that looks like it’s been made in the 80s* (good tuts exist. Just nothing that make you go “oh yeah, I get it”).
If I were the renoise team I’d throw some money on the table to hire Blue Stalhi to make few tutorials. But I don’t think they have extra cash to spend. (actually sometimes, I wonder if they make any money at all)
*no offense to the Renoise team. Renoise is as beautiful as a tracker can be. Trackers are just ugly… (or pretty in their own way).
