Never seen such an editor, what program is that? That's pretty neat. I think it's fascinating that it's structured in blocks.
Anyways, you made a great melody for a fantasy RPG on a vintage device, well done!
Thank you!
It's a tracker! It's how computer (and video game) music was made back in the 80s/90s. It's almost like programming the music. There's plenty of modern trackers as well, but they're more niche now. The one in the video is the integrated tracker in GB Studio, a modern game engine used to make Game Boy games.
