I just started looking at Strudel and was quite pleased to see this! I was impressed that it captured the idea of my prompt, which was fairly simple, but not too typical, I think (a brass call and response).
What would be of most interest to me is to see how you are doing this, but otherwise, something to assist in learning Strudel. For example, take a more complicated piece from the Strudel website and help pick it apart and put it back together. In any case, thank you and I will continue playing with this while it's available!
