Hi, and welcome to mabibeats.
i'd encourage you to join the discord server as well if you wanna do more than lurk. We don't bite! (at least, i can talk for myself. the others, not sure )
Did you try playing the MIDI in another program? Maybe it actually doesn't have any sound to convert into code? I'm not sure what may be the cause otherwise...
This may sound dumb, but make sure you're actually importing the midi (and choosing the file) instead of exporting it. Parsing usually happens when you're trying to export a file.... from what I've experienced.
If you use an all-skill reset, youll only have to rerank the skills, no need to work on the reqs again.
and if you got any master titles, you get them back when you rank the skill again to 1.
I'm pretty sure it's about keeping on submitting original stuff, as a test to see if you're not copy-pasting other people's work or simply trolling.
Or it could just be as Pokemonher01 said idk
Just keep pushing out submissions and it'll come sometime
