While I completely agree with the sentiment, I still wonder what's the difference to graphics. Is drawing easier, for lack of a better word, than gfx-programming? I would argue this comparison is apt and yours falls flat. B flat.
For starters, you could have a skeleton of a script with accessible parameters, given knobs. That would look like a DAW, except for text instead of pseudo design with screws and LCDs that mimic real objects (skeumorphic). Yes, you want buttons, visual programming still sucks. Demo coders like Farbrausch program their own demo tools, eg. Werkkzeug 3, for exactly that reason, isn't it? Considering gfx programming as the comparison, of course textures, models and so on are modeled in an analogue fashion. Nobody programs a human.md3 to evolve from an embryo for fun, but in principle, somewhen it could be done. Music is a lot like vector graphic art, you can do a whole lot with simple shapes and gradients. And you can program complicated sound effects perhaps easier than as a 5 second loop rendered to wav and pitched by the DAW, if you know what I mean.
Note composition as you remark is especially besides the point. The drone noise perspective might be an extremely misleading example, but music programming should be able to paint outside the classical frame. It should allow to define sweet points of resonance, instead of chasing harmony by ear. This does require deep understanding, so instead I'm happy with finger painting ... because it's so close to the metal, err, paper.
It's very sad because I have no idea of the potential. Composition to me is choosing an instrument and arbitrating simple known melodies to complexer ones until it sounds harmonious thanks to obeying the circle of fifths, but that's mostly it and mostly rather superficial, which doesn't matter as long as the instruments sounds niceand if it doesn't I'll split the melody by octaves e.g. and choose two different instruments, alter the octaves to get a high contrast (shout out to my man). Because of the loop nature of pattern based composition, I am mostly not interested in arrangement. This again compares to shader programming. And even big studios basically just stitch together single scenes. ... yadda yadda yadda.
You might also compare the violin to the voice. Far more people can or think they could sing. Making the violin sing is just much more complicated, but not exactly boring.
