Hey,  I'm working on a beat mapper app for music-based games. It's called MBOY Editor (https://vfpe.itch.io/mboy-editor) Do you want to try it for your game? Vic

Probably better to contact them through their Discord server: https://discord.gg/njpsymNA

Sorry to necro the post, but I have an answer for those wondering. This isn’t that kind of music game, it just let’s you watch dancing, and stuff. Nothing to really map.
