Hey, @richard… these ideas probably won’t come to fruition, but…
Can you and your team add an advanced mode to the music editor?
…
Here me out.
I love creating music. It’s one of my favorite hobbies! I’ve created tons of mp3s for games that have never been used. I don’t think uploading mp3s to Arcade would be fair, given the software I use has instruments like trombones… but then I thought, what if we added an advanced mode similar to the software in Arcade itself? Sure, given the method of music creation Arcade currently has, it’s more of a long shot… but you could keep this music editor and just add an advanced mode! You could keep the actual instruments, but add sharps and flats to the lines, as well as the ability to do freehand notes instead only 1/4, 1/8, 1/16, and 1/32. Again, this would take a long time to code and probably is not on the top of your list. In fact, I don’t even think any of these things would come to fruition based on your current priorities. But I would absolutely want to see these changes, being a music maker. This would add more depth to songs, and also keep the old-fashioned 16bit atmosphere.
I don’t mind if you say no, I’m perfectly fine with it! I just wanted to spout off ideas 
Thanks! I hope you consider some of my ideas!
