What list are you talking about?
If you do NOT work with any pre-generated playlists, but always let ProppFrexx generate the playlists on-the-fly and continuously, of course all queued entries are added and checked against the global history by default - except you suppress that explicitly in the script-line!
If you however work with pre-generated playlists, those are only taken into account when you set the ... 'Back-To-The-Future' settings:
Press the ? icon at the top right of the More - Global History setting:
Look-Ahead 'Back-To-The-Future': (Look-Ahead 'Back-To-The-Future')
Tracks are so far added to the history and checked against the history at the time when they are scheduled. For any pre-scheduled (e.g. voice tracked) playlists this is the time when you prepare (voice track) them - which might be a couple of days or hours in advance.
This also means, that when a regular program/script now runs right before such a pre-created program/playlist; its entries might not be checked against those contained in the sub-sequent, pre-created one. This is what I would call a 'back-to-the-future' scenario.
If this option is checked the look 'back-to-the-future' is enabled:
When the scheduler is running, a next program is determined anyhow. This next (forthcoming) program will now be examined further (resp. its related script).
If that next script contains any 'LoadPlaylist' script-line(s) - as any pre-created (voice tracked) playlists would be - these will now be resolved and its contained tracks are then added to an internal additional history collection.
As such, any current global history check (as performed by a current playlist) would then automatically be checked also against the forthcoming playlist entries (even if they have been created days ago).
You define here how many hours in advance you want to check.
Set to 0 to disable.
Look-Back 'Back-To-The-Future'
Tracks are so far added to the history and checked against the history at the time when they are scheduled. For any pre-scheduled (e.g. voice tracked) playlists this is the time when you prepare (voice track) them - which might be a couple of days or hours in advance.
This also means, that when a regular program/script now runs right after such a pre-created program/playlist; its entries might not be checked against those contained in the sub-sequent, pre-created one. This is what I would call a 'back-to-the-future' scenario.
If this option is checked the look 'back-to-the-future' is enabled:
When the scheduler is running and a current program is started, the current playback history tracks are then added to an internal additional history collection.
As such, any current global history check (as performed by a current playlist) would then automatically be checked also against the last played entries (even if this was a pre-prepared playlist and was created days ago).
