mniip's sound element is the best we will get, but I actually have never tried it. Maybe if more than 3 notes at once could be fixed, I could think about adding it.
Also, I never even have my sound on, so I would never hear any of this in average saves. I don't think I would end up using any saves requiring sound.
there should definitely be an option. it could be fun, like people making small theme songs and such, and perhaps volume/temp could be an option? just a thought.
