In Ardour.  For example, the session state file might have seven playlists
(named Audio1 thru Audio7) ordered Audio1, Audio2, Audio3 etc.  But
when I load them into Ardour, Audio1 is topmost, then Audio5 is below
Audio1, then Audio2 is below Audio5 etc.

In other words each time I load a new session, its playlists always appear
in a certain order on Ardour's canvas (reading from top to bottom) but that
isn't necessarily the same order as they appear to be in if you look at the
session state file.  This is something I'd never noticed before and I just
wondered what affects their ordering?

John
