I was excited to see this, but then realized only chapter 1 is done out of what ultimately will/should be a 25 chapter tome.
Strudel docs leave something to be desired as well.
What I've found to be the most useful so far is to ask an LLM to make a line of whatever: a beat, a synth, etc., tweak it, then layer it.
It gives a really good sense of how to architect a song file, which is missing from the little snippets in the strudel docs
