I had a sudden insight:
I don’t really compose in renoise , and I doubt that the original poster really should (although it’s possible to do it with tools such as noodletrap).
What do I mean by this?
I think, based on the discussion in this thread, that we are confusing two different stages: creation , and representation.
Creation is where you come up with musical ideas. What you really want is a very low friction way of approximating what you’re thinking, musically, but the details of representation are mostly irrelevant.
Representation is how you actually pin down what you’ve come up with, and make it real.
Let’s take as an example an aria I wrote recently. The process is different, to a point, because my final product was sheet music, not a recording, but the principles still apply.
I did not start out with blank staves and start scribbling lines. Instead, I sang some ideas to myself, and to flesh them out I picked up a guitar and strummed chords. (I’m a fair guitarist, so it was low friction for me. Other people might prefer to set up an instrument in Renoise and use a MIDI keyboard to noodle things out. Your mileage may vary, but the principle remains the same.) Only after I’d hammered out a meaningful series of tones did I start writing actual musical notation. Composition first, then representation. However once I had written my ideas down I could go back over them and look for things I could update and improve - after which I would improve the representation.
I think that the same thing applies with any DAW, and Renoise in particular. Renoise is not a good tool for just coming up with ideas. It forces you to get too detailed, too early. Come up with ideas first, and then use Renoise to present those ideas. Renoise will then play it for you and if you want to use that and harmonise with Renoise while deciding what your bassline, or top, or chord progression or whatever should be, then Renoise will be a reliable partner, telling you what you did before.
Finally, once you have all your tracks laid down, Renoise will let you tweak and balance and add effects and go nuts.
Maybe this helps? It’s a view on the workflow which might be relevant.
