This one is actually really simple!
The reason it is so simple is because it has derived from ROBLOX, and it uses simple audio IDs instead of a audio file.
999999999, -- this is the audio ID
0|1|5000, -- notes are structured X | Y | MS ,
2|1|8000
The origin for these notes are at 1, 1 (like SSPM, which you will see in the future), but the X, Y are complete wack
2 is up on the Y axis, and 2 is also left on the X axis. This means X is completely mirrored
