I have to try this, see if it fits my work. Just tattooed Aphex Twin logo a couple of months ago.

The multicolor image with the wav files being displayed vertically, if I were to guess. The left side shows columns of your sample bank “ samplebrain”. Right side is your target. It shows how the “samplebrain” selects the most similar “ sample window “ of the target. So, I haven’t the knowledge to drill deeper, but it’s either a visual representation of the process, or maybe the code uses an actual image matching process?

At least some of these images are used for the website.

You might not want that. I was going to post some quip about RDJ's (aka Aphex Twin) code, so I'll do it here.

I could tell this app wasn't written by RDJ, because it's fairly well laid out, and his code has always been that of a messy tinkerer.

He's released several bits of code on the web, most of it pseudonymous and it's always been a hacked up mess. I've "uncovered" him a few times, just by recognizing his chicken scratch code.

Edit: I won't mention any of his pseudonyms, except one that's semi-public and long-retired: eric_hard_jams ("richard james" with the "e" moved). He used that one around the turn of the millenium. If you Google it, keep in mind that some fans later co-opted the handle for their own use.

Edit 2: Also, hi Richard! I'm sure you're reading, and I hope life and fatherhood are treating you well.

Figured it out. Someone can delete my question, if they wish. (facepalm).

( I’m mostly being sarcastic, I’m grateful for any access to new creative tools. But the MagPi issue #65 really lifted my hopes ). https://magpi.raspberrypi.com/articles/aphex-twin-midimutant

Very on-brand for Richard, somehow.

Thanks for the link, looks interesting.
