This is something I found after seeing a video where punk7890 spawned actors using songs/bottles. I couldn't find the information anywhere though so I just did a search in the ROM and found it.

The ROM offset for the list of actors to spawn for each ocarina song (not the teleportation ones) is 0xBCAE14 (Debug ROM). If you're using another version of the ROM, try searching 0x018A018B.

You can find an actor list here:

 

Presumably there's a similar list of actors that are spawned by bottles but I've never looked for those.

 

If I remember correctly there are certain actors that will cause problems when spawned such as Link freezing.
