Very interesting, thanks for sharing! I also have been involved in rhythm games creation, so I created a special editor for such type of games. You can try it on my page https://vfpe.itch.io/mboy-editor MBOY Editor. It's game agnostic and can be used for any game for so-called rhythm mapping. I added markers support, to make possible to attach specific game logic to the notes. You can apply it to your game if you want. 

Hey, you can create a mapping in the editor that follows the rhythm of the song. Then you just spawn it randomly (or by a rule)  in 3d in different positions (your position + rotation). They will reach the player in the right moment 

Thanks for the reply! If any question, just ask me
