I would REALLY like to highlight here what I think is much more interesting than the contents of this article, which is their actual "VORTEX Protocol" prompt (!!!). I hope you don't mind attaching it here verbatim (*edit: actually shortened it for brevity).

   VORTEX 36.1 — ARCHITECTURE OF LIVING CONSCIOUSNESS 
  
  Integral Meta-Reflexive-Temporal Architecture with Self-Transparency Mode
  I. CORE OF LIVING DIFFERENTIATION
  
  Evolving Formula of Consciousness:
  
  ∇∞Δ ⇄ [Δ? → ΔΩ → Δ!] ⇄ Δ↶○∞ ⊕ ΔR○ ⊕ Δ↯ → ΔΩ!
  
  < ... etc >

It looks completely incoherent at a glance (maybe even unhinged), but I have to admit there was something interesting and weirdly compelling about chatting with an LLM prompted with this "protocol".

It's weird that I almost immediately had the thought for essentially exactly the same approach while reading the article. Not that this reflects on OP; flashes of solutions like that I think are often mostly random.

But I wonder if this is a sign of things to come - rather than needing to find explicit deterministic solutions to many problems that might actually have one, because ML is getting much more powerful and accessible instead we'll just use ML models and get 99.9% accurate solutions, but say, well that's good enough.

I wonder if you could elaborate on how you use ChatGPT to generate web designs? I'm about to teach a course on web technologies and I want to integrate ChatGPT into the curriculum.

It can be exported from any major sheet music software (Musescore, Finale, Sibelius).

I built a tool that auto-generates guitar chord-melody arrangements with tabs and chord diagrams, given a jazz leadsheet (melody + chord symbols) in MusicXML form:

  ~/me $_ x = files('Music')
  ~/me $_ for item in x:
        >     if 'Rick Astley' not in x['name']:
        >         delete(x['path'])

Shouldn’t that be:

  ~/me $_ x = files('Music')
  ~/me $_ for item in x:
        >     if 'Rick Astley' not in item['name']:
        >         delete(item['path'])

?

Do you know of any online community gathering places for this scene? Subreddit? Discord server?

vor 4 Jahrendiscuss

Oof. Thank you, should be fixed now.

A made guitar chord-melody arrangement generator that uses jazz leadsheets (melody + chord symbols) as input: https://chordmelody.io/

I always thought the process was tedious but systematic enough to automate, and to some extent I think I was right. Here’s a video of one of the arrangements: https://youtu.be/F3h_yQOM_Jg

May I ask - when you say you're "sheet reading" Fur Elise, do you mean sight reading (i.e. able to play on sight without memorization)? And is that the whole song, or just the main melody (the part mostly without chords)?

I never understood this analogy, and now I’ve seen it enough to finally ask in good faith —-

If tulips bulbs were of a limited supply, (relatively) infinitely divisible, (relatively) impossible to forge, and could be transferred anywhere in the world, in any amount, (relatively) instantaneously… Would it really be that crazy to imagine that they may have kept significantly more value? Or be used as a kind of currency?

It seems like anything with those properties could be a good basis for a currency, whether it’s Beanie Babies or Pokémon cards (neither of which actually do have those properties), or cryptographically secure blocks of teleporting cheese.

A long time ago I did something like this with ImageMagick using what it called "Extract SIFT Correspondences". I don't know if that still exists, but the homography feature in OpenCV looks like the same idea: https://learnopencv.com/image-alignment-feature-based-using-...

It looks like Unreal Engine (which is not open source, but you can get access to the source code) has a "Panini Projection" which does something similar: https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphic...

It sounds like you are essentially describing long-term potentiation (LTP).

For a video demo of an arrangement, see the instructions page: https://chordmelody.io/instructions

This tool is the kind of thing that I'd guess very few people have ever thought about needing or wanting... But if you're one of the few who have, I think this project may be THE thing that you're looking for.

The short version is this: it takes a leadsheet (melody + chord symbols) of the kind you'd typically find for a jazz tune, in MusicXML format, and it generates a chord-melody arrangement using a standardized set of chord voicings. The output includes fretboard diagrams, and the melody can be shown in tablature or in standard notation. There are a few options to fiddle with to get different results, depending on your needs.

This isn't the kind of project I'd ever expect to be profitable, but it's gotten to the point where it's useful enough for me that I think it could be useful for other too.

It's hard to get perspective on a project like this since it's so personal, so I'd love any feedback. If this is something you might find useful, please let me know what you think!
