Hi Cad,
The M3U entries above are simply lines from my mAirList Commands.m3u file. I originally created it via Playlist in mAirList - ie: Add a DUMMY item, set the Title and save etc. Now I know all the parameters, I simply make new ones via NotePad.
#mAirList is used in M3U playlists to precede any mAirList action (Break, Command, Dummy, Stream etc). The 2 schedulers that I am familiar with (Natural Music and StationPlaylist Creator) allow you to specify what I’d call “Break Notes” to the actual Playlist. It’s up to the playout software how it treats each playlist line (some just need a filepath, others may want a CutID or trigger like M, J for music/jingles etc). StationPlaylist Creator is quite a popular scheduling program which can schedule music based upon set rotations (ie: don’t play ABBA songs more often than every 4hrs) and Ads/Jingles on a sequence or random basis. Non-Audio “break notes” can also be inserted to tell the DJ to do a link, read the weather or plug a gig etc. You can also insert Automation Breaks, Commands etc.
mAirList simply requires that #mAirList appear on a non-audio line. For example, the first few lines of my 4pm hour in M3U:
#mAirList DUMMY 0 16:00 : WEEKEND ALTERNATIVE
#mAirList COMMAND [OnAir - Weekend Alternative] RUNSCRIPT S:\mAirList Files\OnAir - Weekend Alternative.mls
S:\IMAGING\TOP OF HOUR\Top Of Hour - Hot Rock.mp3
Z:\MUSIC\Feeling - I Thought It Was Over.mp3
S:\IMAGING\GENERIC IDENTS\ID - Generic Ident 7.mp3
The Dummy and Command entries are inserted into a “Rotation” in Creator. A Rotation is a single hour template (you’d have one for a rock show, one for a jazz show etc). You then tell the Scheduler which Rotations to use in each “hour” ie: 24 rotations in a day.
Here’s an example of how I would use a Dummy:
The %2h is the current hour in 2 digits, ie: 16 for 4pm.

In the Global Config on Creator, there is a textbox called “Break Note Format” (a screen shot is in the Scheduling Wiki). In that box is #mAirList %t - The %t token is whatever text appears in the Rotation, so all Break Notes have the #mAirList trigger. The entire contents of an M3U playlist can be displayed as a Browser pane. In my standard.mlt - the entry looks like this:
[] in a Command is a DJ-friendly description. You could always have the actual command line in there, but RESUME AUTOMATION tells a DJ in simple terms what RPC http://192.168.0.1:9300/BIN AUTOMATION 1 NEXT wouldn’t 8)
Long-winded, but I think that just about covers it!
