I've been thinking of and briefly working on a similar project.
One idea is to analyze timing as well, and "trigger" things after certain sequences (so play 1-3-5 as say eighth notes and then get an in-rhythm arpeggio one octave higher) or detect the beat and play on the upbeat.
I haven't done any Rust, but this might give me a good reason to give a try.
Have you considered making it a plugin? (makes replay easier in my opinion, but brings other pain like relaunching the DAW between builds...)
I like this fairytale as an analogy for AGI, but this article misses the point.
We are the mouse.
> I don’t really believe in the threat of AGI
Just like the mouse doesn't believe in the Gruffalo (until it shows up).
The mouse goes through the woods scaring the hypothetically-more-dangerous creatures with its stories (us, using our intellect, weapons, destroying habitats) until the real Gruffalo shows up.
For a bit, the mouse "uses" the new tool to scare the animals even more (as alluded, human with tool, scarier than without).
Eventually the mouse scares the Gruffalo away (analogous to the brief window when we think we have AGI under control).
The next (unwritten) chapter probably doesn't look so good for the mouse (when the gruffalo grows to enormous size, eats him and all the other animals in the woods on a sandwich, and sucks up the rest of the resources on the planet.)
