 The final step is option "​Follow System BPM"​. ​ This is real simple model. **IF** this option is **On**, **THEN** the timeline will use the Global Beat source **Otherwise** it will use timeline BPM setting. The final step is option "​Follow System BPM"​. ​ This is real simple model. **IF** this option is **On**, **THEN** the timeline will use the Global Beat source **Otherwise** it will use timeline BPM setting.
  
-What we should expect? ​As you use, timeline use own or global setting and calculate position as beat and clock. All of the Images and Effects which use Beat as argument - they will react, and you will see impact of BPM change. Clock based, or Duration based effects - they do not use Beat, and you will not see any impact of BPM change. Same logic used in other places of BEYOND.+What we should expect? ​When you use, "timeline use own" ​or "​timeline uses global" ​setting and calculate position as beat and clock;
  
-Lets consider one more detail ​timeline with variable BPM. After such explanation many people still have a feel that something is wrong. Let offer one more scenario for consideration. Timeline where BPM change for parts of songs. As example, what I saw on audio editors, you can set point where BPM change ​to some value or goes up/down to some valueIt happen on timeline positionand stay on this position. It means position is a primary parameter, and Beat value is a slave parameter. It can be fixed during a whole timeline, or variate (of application allow this feature)Main thing - Beat is a calculated (slave) parameter. ​ BEYOND keep direct relation between position and clock+All of the Images and Effects which use Beat as argument ​will reactand you will see the impact of a BPM change. ​Clock basedor Duration based effects ​do not use Beat, and you will not see any impact ​of BPM changeThis same logic is used in other places of QuickShow.
  
-OKwhat if I want the beat be primary thing? if to do this, then it will break solidity of Events OR beat will influence time speed. Time will move faster or slower. And if yes - then this is different story, because you want to play a whole timeline (clock and beat). This is Player level option rather than Timeline level option. This is similar to follow timeline situation when a a whole timeline need to move faster or slower.+Lets consider one more detail - A timeline with variable BPM.
