I tried making short MIDI loops, for use in RPG Maker XP projects and came up with this.
I also tried replacing the MIDI instruments with actual VSTs, so I could upload that onto Newgrounds... but it didn't turn out so well. So, I just saved the MIDI file as an mp3, and we ended up with this (but I like how it sounds, as is, so it's a-okay).
I've seen others upload original songs using MIDI instruments, so I guess it's okay for me to do the same. Let me know what you guys think.
