I'm trying to make a louder version of one of the original sound effects (specifically, the Valley of Bowser earthquake rumble), and it is proving a lot harder than it has any right to be. The original sound effects are included with AMK, but only as hex data, and it doesn't seem to follow quite the same format as music. The data for the original earthquake SFX looks like this:
$DA $11 is easy enough, $FF is obvious, and the $8x's are presumably note values (and low notes at that), but...I'm not so sure about all the other stuff, and I especially can't tell how it handles the volume for each note. I thought AddmusicK's readme had documentation about the format of music and sound effect hex data, but apparently not. Could anyone else shed some light on this?

I'm working on a hack! Check it out here. Progress: 64/95 levels.
