Spoiler: Offsets in info.bin of the SDAT

all in info.bin


0x40 - main table
each entry 0x0C long, ends with 40 00 00 00
first word is sseq id
byte 4 controls which sound banks are loaded
bytes 6 and 7 control which byte 1 and 2 need to be selected in sm64dse

MINICLEAR 0x1C0
PLAYROOM 0x1CC
MINIOTATE 0x1D8
JAZZ 0x1F0
CASIO 0x1FC
MINIMERRY 0x208
MINISNOW2(Rolling Star) 0x220

OPENING 0x4E4
STAFFROLL 0x4FC

Open up info.bin from the sdat and go to 0x40 for a table.
First word is the number of entries in the table, each after it is a pointer to details on each sequence and the sseq/sbnk/swar loaded.
After going to where one of the entries points, you'll find the first 4 bytes identify the sseq.
The next 4 bytes identify the sbnk and swar, also effecting which byte 1 and 2 need to be set in order for the music to play in your level.
You can easily copy these from any other sequence to use the same instrument sets multiple times.

Spoiler: Object Visible Distance

02111a3c - possibly clock seed

02111a50(021118a8) - ct mecha 10 rotating

02010e20/0201160c - writes max range on level entry
