Not answering your question, but if you're interested in audio programming you might find Pure Data interesting, it's sort of visual audio programming. It might seem like a toy but it's actually incredibly powerful: https://puredata.info
Purr Data is not really more “up to date“, it is rather Pd vanilla with batteries included + a nicer UI. Both are actively developed. Note, however, that they are not 100% compatible: both have features that the other one is (still) missing.
Second for puredata. It's pretty different from other options but very powerful. It's also quite visual and uses the same kind of design concepts involved in setting up a traditional modular synth.
