Actually, I had set myself a task for today to try exactly this, making more complete song structure with A4 and Rytm, so I’m also interested of any tips!

I have an extra question concerning this (sorry OP, not trying to hijack the thread…):
If I make a song structure, can I play back the whole “song” and live-record for example parameter changes and modulation over the course of “song”? I presume that this can be done, but of course recurring parts get then those changes repeated?
