Summary0009594: MIDI Cue Track Breaks if Played Past End of Loop Range
DescriptionIf a loop range is set and a MIDI cue is playing when the playhead jumps to the start loop marker, the clip is abruptly cut off and will not be triggered again unless playback is stopped.
Steps To Reproduce1. Create an empty project.
2. Add a MIDI track, ensuring "Show on Cue Page" is checked.
3. In the Cue window, drag a MIDI clip (e.g. 1_groove_16beat1.mid) to cue slot A of that track.
4. Set both follow actions of track 1 cue A to "Stop," and set its Launch Quantize to "None."
5. In the Edit window, add a Loop range from the start of measure 1 to the end of measure 2.
6. Add Cue Marker A to either the beginning of measure 1, or anywhere in measure 2 after beat 1.
7. Enable "Play Loop Range" and press Play.

Actual behavior: The cue will trigger once, but will abruptly cut off and never trigger again once the playhead loops.
Expected behavior: The cue will continue playing after the playhead jumps back and can be triggered again under normal cue rules.

This also happens in Linux 8.4 from on Ubuntu 22.04 LTS and Windows 10 Ardour 8.4 downloaded from

A semi related bug is that I have occasionally found that CUE tracks are possibly exported when muted. Causing a doubling effect on audio mixdowns of the CUE track. When I can replicate successfully, I will add to tracker.

Interestingly, when CUE is not playing after looping, if you disable looping(Shortcut = L 'Loop Playback Range'), the CUE will start back up wherever you are at in the loop range.
