Contrapunk is a cool name though.

How are you finding rust for audio development? I have a background in pro audio, and both for the audio and GPU render threads, I used a lot of arena allocators and ring buffers. Do you find yourself fighting with rust's strict semantics?

This is callback heavy audio code so this was the bigger problem for me mainly and learning about lifetimes was a pain initially. cpal's stream callback wants 'static which means you can't just pass references around. You end up using channels (crossbeam / std::sync::mpsc) between the audio thread and everything else. Once I structured around that it got smoother. I also got a lot of help from AI to understand and reimplement a lot of the parts for this as you can tell from the commit messages.
