Ah, yep. That did it, thanks! That's interesting that it would crackle like that. I suppose the game's sound engine mixes it similarly to how I'd mix a song on a console or in Pro Tools. Do you know of any resources I could use to learn more about the mixer? Sorry for geeking out- this stuff is pretty fascinating to me ^.^
You may be able to glean some knowledge from this tutorial. It helps you upgrade pokeemerald's mixer. I've yet to take a real dive into it myself, but I know it can remove a lot of the limitations of pokeemerald's sound system.
Hey, would you be willing to share your General Midi voicegroup?
Sure! I will say that I do most of my music work on an older version of pokeemerald, so you'll need to make some small adjustments to a lot of the voices in this voicegroup to make it fit the updated formatting. There are also several custom voices that I've added, so you'll either need to add those samples yourself, or swap it out with a dummy voice.
