Yeah for the scales, one thing I've been thinking about is, instead of the individual "position" diagrams, which I agree don't really add that much, adding the ability to mark off part of the "entire fretboard" view with some sort of 4 or 5-fret box to play around with positions.
Banjo would probably make sense and be straightforward. But since I don't play banjo I wouldn't have any way to verify that it's right. I do recommend just forking this and telling codex or whatever "add a Banjo setting to this" — good chance it'll get it right in one shot.
But I agree it's not enough. The problem is, there are as I see it really two options here
(1) Guide the LLM and just spend more time on the visual stuff. The trouble is those refactors take as much time as adding major new features, sometimes more, because the LLM doesn't get it right and you gotta go around and around. So it takes a big time investment to go from something that's pretty good to something that's merely somewhat better.
(2) The other option is to do it all by hand. I sometimes do some of this, but the further along you get the harder it is, because the LLMS write lots of CSS, and (at least the last time I tried) refactoring their stuff is time-consuming and kind of a prerequisite to tweaking things.
Probably what I should do is expand on the design spec, and add it to AGENTS.md (instead of just throwing it in on the initial prompt) and generally try to get good on this aspect.
I should note that on my "real" project (https://flipper.fm), I spend a lot more time steering the design, creating a component library, Storybook, creating CSS classes for the LLM to use, etc etc. Again, this thing is a toy.
Sorry for the long answer, but you're really hitting on something real here.
I added that after posting this. You can click any note on the scale, and there are play buttons on the chords. The sound will vaguely approximate the current instrument. On the Compose screen you can select the sound. I'm working on improving the sounds, this is just a first pass.
Agree, this is very much about where I am and not for beginners. But I think it helps learn the one “big pattern” when you see where the different scale degrees fit into it in each mode?
Yeah! I came across a book that was literally just fingering charts for all these scales in all the keys and I was like, wait a second, this is dumb...
I've thought about adding something that would vamp certain chords, say. But sounds like you mean something different... like, play the pitches in a scale?
I very much would like some way to preview what the sound and feel of certain combinations of chords and scales/tones is, but I haven't quite figured out how it might work.
