Command-shift-k / command-shift-j ftw… these features have already become essential to my renoise workflow. Recently started doing some orchestration work and it is so nice to be able to take 12 track parts and fold them down into a single “orchestra” or “melody” channel. I’m also happy I don’t have to use send tracks as busses anymore.
All in all, these features have really empowered me to work with projects having much more complexity and abstract them appropriately into something simple. Thanks devs!
