Why Is MusicMaster Violating My Artist Separation Rules? publicado em October 20th, 2026

You’ve carefully configured your Artist Keyword Time Separation rules, but when you review your schedule, you notice songs by the same artist playing closer together than they should. What’s going on? While it might appear that MusicMaster is ignoring your rules, there are several reasons why an artist separation violation can occur. Here are eight common causes to investigate and how to identify them.
1. The Category Is Bypassing the Rule
If your Artist Keyword Time Separation rule is configured under All Categories, check whether the category in question has been excluded.
Right-click All Categories in the Rule Tree and select Rule Tree Properties. Any category checked in the All-Category Bypass list will ignore every All Categories rule, including artist separation.
2. The Rule Isn’t Active for That Time or Category
A rule may be configured correctly but not active during the hour in question.
Right-click the category and select View Category Rule List to see exactly which rules are being tested for that category at a particular time.
If your artist separation rule is inside a Rule Group with time restrictions, it may not apply during certain hours. Try changing the review time in the window to confirm when the rule is active.
3. A Custom Keyword Setting Is Overriding the General Rule
Individual artist keywords can have their own separation settings that override the general Rule Tree configuration.
You can review these settings under Dataset/Library/Keywords or through the keyword’s Keyword Properties dialog.
If an artist’s individual separation time is set to something other than Auto, that custom value takes precedence over the Rule Tree setting. As a result, a song may pass rule testing even when it appears to violate your general artist separation requirement.
4. Category Exclusive Mode Is Enabled
Check whether your Artist Keyword Time Separation rule is configured to use Category Exclusive Mode.
When this mode is enabled, the rule only evaluates songs within the same category. Two songs by the same artist in different categories won’t be tested against each other for separation.
If you expect artist separation to apply across multiple categories, this setting could explain the apparent violation.
5. The Song Was Scheduled Without Rule Testing
Not every item placed into a schedule goes through the normal rule-testing process.
For example:
- Saved Song Lists: Items scheduled through a Saved Song List do not undergo rule testing.
- Forced Positions: Songs placed in forced positions are scheduled automatically without being tested against the rules.
Other songs scheduled around these positions will still be tested against them, but the forced or saved-list items themselves can create apparent violations.
6. Someone Manually Edited the Schedule
A song may have been placed into the schedule manually after the automatic scheduling process was completed.
To identify these changes, add the Schedule field to your Schedule Editor view.
Any position marked with an M was manually placed and bypassed automatic rule checking.
7. Runtime Differences Changed the Song Spacing
During automatic scheduling, MusicMaster uses average runtimes for categories that haven’t yet been scheduled.
If the actual songs selected for those positions run shorter than their category averages, previously scheduled songs can end up closer together than originally calculated.
This can produce an apparent artist separation violation even though the songs passed their rule tests when they were initially scheduled.
8. Network Elements Were Imported After Local Scheduling
If your station imports network programming, the order in which you build your schedule can affect rule compliance.
Importing network elements after scheduling local music may introduce conflicts with songs that were already placed.
To avoid this, Import from Network first, then schedule your local programming around those imported elements.
How to Diagnose an Artist Separation Violation
When you encounter a specific violation, the Test Results panel in the Schedule Editor is one of the best places to investigate.
Open the full Rule Tree for the position and examine the color associated with each rule:
| Color | Meaning |
| Green: | The rule passed. |
| Yellow: | A breakable rule was violated. |
| Red: | An unbreakable rule was violated. |
| Black: | The rule was not tested, often because of a rule bypass, or some condition that was already met in a higher-level rule or rule group. |
You can also hover over a rule to see its settings and how close the song came to passing the test.
This information can help you determine whether the issue involves an inactive rule, a bypass, a scheduling exception, or another factor.
Getting Your Artist Separation Back on Track
An apparent artist separation violation doesn’t necessarily mean your scheduling rules aren’t working. Often, the explanation lies in a category bypass, an individual keyword setting, a scheduling method that skips rule testing, or a change in song timing.
Start by examining the affected position in the Schedule Editor’s Test Results panel, then work through the possibilities above. Once you identify why the rule wasn’t enforced as expected, you can make the appropriate adjustment and get your rotations back on track.
