Creating hourly playlists is possible using the Playlist Generator - it allows creating multiple playlists in one go.
I have looked at this in Ver 6.2
I am still not able to ascertain just how hourly Playlists are accomplished. I have read thru help.
For Example I want a Playlist that says 1pm, 2pm, 3pm etc (every hour for a whole day) followed by enough tracks to be maybe extend each hour to 1 hr 8mins say in length.
Example : An hourly Playlist created for 2pm today, and then (say 30 secs or 60 secs or maybe even 90 secs before the hour) at 2pm to move up into (wiping out all previous tracks existing in Playlist, including the current playing Track but not stopping the current play track playing) and inserting the new 2pm Playing List.
It doesn't have to be exactly like that.
Anything that will shuffle the old Playlist away and insert a new hours worth of tracks would do. One hour at a time.
Something and anything better than we have now, just to give some timing regularity to a whole days worth of traffic just being plonked into the Playlist as happens now.
I can think of Eventing a new Playlist Generation every hour, and then inserting it every hour, but I don't see why Generation cannot do the same thing by making a whole day of hourly Playlist/s in one go.
