Nothing there or in the manual nor in several web searches - at least not an explanation about what these letters are intended to refer to. You see them displayed on some mp3 sites in amongst other metadata but nothing meaningful, just the default Cubase string: CCOOONNNNNNNNNNNNHHMMSSRRRRRRRRR
There is such a thing as the International Standard Recording Code (ISRC), which I thought might be it, but that’s only 12 characters (CC-XXX-YY-NNNNN). I suppose CC could be the Country Code from there, maybe OOO is the XXX referring to the organisation, but the YY (Year) is missing and it only allows 5 characters for name (NNNNN). HHMMSS must be some sort of timestamp but which one? What the Rs are, I’ve no idea.
Surely this must be some sort of (semi-)official reference intended to be parsed in a certain way. It seems so structured that I would like to know a bit more about it.
