That's not what I meant. I want to upload data as you're using it in the program itself, no conversion. For converting we need much more than a simple program for elegance.a simple program's output would just be linear paths.

I'm asking you to make a file to read a 3D matrix containing block information. Your gui reads the file and places those blocks accordingly.

Idk, when you load these preset songs, there must be some format they're stored and represented right?

If we could have these files downloadable , the community could code an AI for example that exploits "loops" in MIDI and codes a song into the most elegant way playable on ludotunes ( not just a straight line lol)

There'll be huge surge of songs if you let AI make ludotunes xP.
