Just trying to understand the behavior with these options and didn't see this described explicitly in the help files, but experimenting it seems as if:

1.With Zero Controllers When Playback Stops disabled, MIDI event/note chase will find notes and events when starting playback after a "Stop" command, but NOT after a "Pause" command.
 
2. With Zero Controllers When Playback Stops enabled, MIDI event/note chase will find notes and events when starting playback after a "Stop" command AND after a "Pause" command.
 
Just wondering if this is the expected behavior. With certain VST plugins like Maschine 2 I have to disable Zero Controllers or they receive erroneous pitch bend messages.
