My 30 minutes compo track from last week since I forgot, whoops.

Summer Dive 95 (Luna Festa 07/17/2022)

Hi! I've been quietly and skeptically studying machine learning for a few years, and this is my first result worth sharing.

What you're hearing is not AI-composed, it's a cover of my own chiptune, created by Riffusion, a spectrogram-finetuned ML model based on Stable Diffusion. No external samples, effects, or synths were used, just the original unaltered NES chip track (https://virt.bandcamp.com/track/the-buzz-in-the-grotto-troupple-pond) and the following text prompt:

"A rocking latin jazz fusion track, recorded 1960, big brass sections, muted trumpet, acoustic guitar, piano montuno, flourishes and high energy throughout, salsa pop dance, it's time to party yeah boiii"

To create a stereo effect, I incremented the seed and the denoising value a tiny bit to create a slightly different mix, and panned these left and right. I suspect the reason it works is that the chiptune was already written to imitate "live instruments" in chip form. The model is eerily good at inferring the same timbre and performance techniques that I was actually trying to go for. 

In other words, you can now write a chiptune as an "MSpaint scaffolding version" and then turn it into amazing future sounds. I named the technique neurochip, and I'd love to hear other people trying it out!

I'll post a guide as soon as I can get some good screenshots of my process and maybe get in touch with the people working on Riffusion.

Neurochip 01 - Buzz in the Grotto

I'm exploring ML arrangements with more than just chiptune music! I'm sharing this one out of the handful I did tonight because it went past "holy shiiit" and actually made me tear up a little.

The source song was a SNES-style MIDI piece from my Boot Hill Heroes soundtrack - basically the same notes, but with basic synth sounds. I used it unaltered as input, and wrote a prompt: "1972 soundtrack for a beloved italian wild west film about a mysterious stranger, harmonica over orchestra with (baritone guitar) and abundant choirs".

(Yes there are new notes in there. I like them too, and it took a lot of tweaking numbers and specific words to get them to do that, but it will get easier and better soon!)

■Comment■
This is an arranged version of the Final Fantasy 4 main theme.
Similar to the arrangement of FF8's Laguna, I made bold and extensive changes from the original composition.
I felt relieved when I switched to HalionSonic because Nexus strings didn't quite fit the sound I wanted.
The original theme from the game played while roaming around for a long time in the field, trying to obtain summoning items like Goblins and Cockatrices.
I listened to it quite extensively during that time, so I didn't reference the original composition while working on this arrangement.
I apologize if there are any mistakes.
I hope you enjoy listening to it.
