Often times we are asked which Hour Rotation rule to use, and many times we end up explaining the differences between “Day Offset Window” and “Sliding Day Offset Window”. Here’s the scoop…

Day Offset Window is used to protect X number of broadcast hours for Y number of days on either side of a play being tested. The most basic setting here is “Days=1/Window Size=1 Hour”. This protects a song from being played two days in a row in the same broadcast hour.

Sliding Day Offset Window with a setting of “Days=1/Window Size=1:00” would protect a song from being played two days in a row while sliding that 1:00 over the time being tested, splitting it in half so as to check +/- 30 minutes on either side of the play being tested.

Let’s assume we’re testing a play at 9:05am on Wednesday. Day Offset Window is in place with that “Days=1/Window Size=1 Hour” setting. This would look at the 9am hour on Tuesday (one day back) and Thursday (one day ahead), and if the song played anywhere within the 9am broadcast hour on either day, it fails the rule. Note: if the song played at 8:55am on Tuesday, the 9:05am Wednesday play would pass this rule as it is in a different broadcast hour.

Now if we have that same play at 9:05am on Wednesday, but this time we have a Sliding Day Offset Window in place with a setting of “Days=1/Window Size=1:00”, MusicMaster will look at Tuesday (-1 day) and Thursday (+1 day), and if that song played within 30 minutes either side of 9:05 (8:35am-9:35am) on either day, it would fail the rule. Note: if the song played at 8:55am on Tuesday, the 9:05am Wednesday play would fail this rule as it is within the +/- 30 minute window.

Let’s take it a step further. We’re still looking at that 9:05am play on Wednesday. This time our Day Offset Window is set to” Days=1/Window Size=3 Hours”. MusicMaster will look at Tuesday and Thursday in the 8am, 9am, and 10am hours (same hour plus the hour on either side for a total of 3 hours) and if the song played within those hours on either day, it would fail the rule.

But if we used a Sliding Day Offset Window set to “Days=1/Window Size=3:00”, MusicMaster will effectively slide that time frame centering it on the play being tested with an equal amount of time on either side. This would mean +/- 1:30 on either side of 9:05am, or 7:35-10:35am.

The Sliding Day Offset Window can be more precise than the Day Offset Window, because Sliding windows can be adjusted to the minute. For example, a setting of “Days=2/Window Size=1:44” will protect +/- 52 minutes on either side of the play being tested for 2 days back and ahead.

In both Day Offset and Sliding Day Offset windows you can check the “Test Past days only” box on the rule properties window to do just that. Then MusicMaster would only look at past play history and not test against future spins.

Using a combination of Hour Rotation rules including Day Offset and Sliding Day Offset Windows can help maximize a song’s day-to-day separation and exposure.

Looking for a fast way to identify which rules (and in what order) are being tested on an individual category? VIEW CATEGORY RULE LIST is the answer!

In the Rule Tree, right click over a category folder. On the context list tha pops up, select the choice for view category rule list. When opened, it will show you all of the rules, combining any All Categories rules with the rules applicable to the category. If you are using any Optimum Goal Scheduling, those rules will be listed at the bottom of the list. Should you wish to view the rules on a particular day and time, simply change that in the box and select “GO” to see the updated rule list. You also have the option of toggling to amother category rule view after you’ve selected this for a previous category view.

I think this is a great way to “double check” your Rule Tree set up work, and/or often very quickly identify if a particular rule is being applied (or perhaps if it isn’t and should be)…As always, if you have any questions about what you are seeing in the Rule Tree, get in touch and we’ll be glad to look things over with you!

Here’s a very cool Rule Type available in MusicMaster: AutoKick. Find it in the “Song/History Rules” folder, then in the subfolder of “Hour Rotation Rules”. While this rule type can accomplish the same goal as setting an Hour Rotation, Day Offset Window of 1 day, 1 hour, the window size you set can be more narrowly defined. You can set a breakable or unbreakable rule for a category that is defined to the quarter hour, half hour, as well as a full hour! I like to suggest this to programmers who have very fast music rotation categories, or where you are simply trying to make certain that the same non music items (sweepers, positioners, jingle elements, as an example) aren’t falling into the same positions daily.

If you are a new MusicMaster user starting out with a brand new database, I like to recommend a few simple rules to get things going. (more…)

One of the least-used and probably the least-understood property of the Rule Groups in MusicMaster is called Group Mode. (more…)
