Here are some things you should know about ClockWheels and track rotation scheduling. Please read the introduction to ClockWheels first.
One Category per Type, please.
Currently, ClockWheels does not support using the same Category across more than one track Type. Recall that a type is a file such as Music or Promo. A category is like a tag, such as "new songs" or "synthpop".
Here is an example: Let's say you used a category called SUMMER2018 to organize your recently uploaded Music files. You also used the SUMMER2018 category on your Station ID's. This is going to cause unexpected results when generating a ClockWheel that calls for a track from the SUMMER2018 category.
Because of this, we suggest limiting your use of categories to only one type of file. In our example, we could "tag" the Station ID's using a different phrase such as hotIDs. By using unique categories for different types of track elements, we ensure ClockWheels understands what we are trying to accomplish with our clock line items.
Separation Rules and how they affect ClockWheels
The AutoDJ Separation Rules you have configured directly affect the pool of available tracks that a ClockWheel has to pick from when you go to generate a new event. The ClockWheel module first looks at the specifications of each line item you've entered. It then checks the separation rules before creating the event on the Scheduler. Just as with regular playlists, it needs to check which tracks are playing 4 hours before the event and for 4 hours afterwards.
Because of this, you may see an error message about not being able to generate the event. If your rules are in conflict with the configured Selection Algorithms and the length of the event, the system will not be able to create the event as requested. For example, let's say your ClockWheel had 4 items in at shown here:
The scheduled event will play 4 kinds of elements for every loop it is scheduled. It will start with a Music track tagged with the SUMMER2018 category, then a random Music track followed by a track from the rock category and then an ID type. This pattern will repeat for the length of the scheduled event, so about 6 to 8 times an hour depending on the length of the song. However, we get an error when we go to schedule the ClockWheel for a 3 hour long event.
Why? It is because we only have 2 tracks in the SUMMER2018 category and it knows not to repeat those tracks over and over. It's a DMCA violation, in this example, and you may see a similar message due to a Separation Rules violation.
Normally, you may see error messages caused by not having enough unique tracks or tracks with incorrect metadata such as "Untitled Album". When ClockWheels displays an error, it is caused by either your separation rules or you are trying to make an event that would repeat a track, artist or album too many times.
