I've just had something like this happen in Ardour 6.6. A few of my MIDI clips have suddenly become empty. My data is lost, I don't know what was there, I need to recreate it from scratch. It's really frightening that Ardour does this. Screenshot_20210226_124723.png (45,295 bytes) |

This kind of data loss happens regularly in my projects, and without warning. The MIDI files just become empty. |

This happened again in another project. I created a snapshot of the project (I will call it snapshot 1) and worked in it (did Stem Export, duplicated midi tracks, combined all regions into one, deleted notes). Then I opened the main project again, made another snapshot (I'll call it snapshot 2). In this snapshot, I merged all midi regions into one region (for one track) and exported this midi region to a midi file in the export directory. Then I opened snapshot 1 again and got a message about a missing file: "This session misses following midi files. They have been replaced with silence: Twang21.mid The Regions and edits have been retained. If this unexpected, manually locate the files and restore them in the session folder. Editing the MIDI files by adding new content will re-create the file and disable this warning, but also prevent future recovery of the original in the existing region(s)." It should be noted here that I did not work with the track used by the Twang21.mid file in any way. I would also like to draw your attention to the fact that, like last time, the disappearance of files occurs after creating snapshots and working with them. |

Another extremely interesting observation: after I opened the main project, and then snapshot 2, the Twang21.mid file I created disappears again! I did some more experiments: I created the Twang21.mid file, opened snapshot 1, closed Ardour and the file did not disappear. Then I opened snapshot 2, the file still did not disappear. Then I closed Ardour and after that the file disappeared. The same thing happened if I opened the main project instead of a snapshot 2. |

And it happened again. 3 files from another project were lost. Yesterday at the end of the day, I made one new snapshot and then a complete copy of the project (just copied the directory with the project). Today, when trying to open the project, there were 5 crashes. After upgrading to 6.6, projects often crash when opened. If this happens 2 times in a row, then I use one trick that helps me open the project: I do not open the main project, but the snapshot and snapshot, unlike the main project, opens successfully. After that I close the DAW and reopen the main project - after that it opens well. This time I did the same. Having survived 5 crashes, I opened the snapshot, closed the DAW and reopened the main project - it opened, but 3 files were lost. I found them in a complete copy of the project directory (which I made yesterday). From this we can conclude that snapshots are definitely involved in the loss of the file. Using snapshots is not safe. There is still an unverified version that NTFS is to blame for everything. My projects are stored on an NTFS volume. Can anyone tell if this could be the cause of the problem? |

This should be fixed since Ardour 6.7 (really since 6.6-146-g4bb3a896b4) -- please test and keep an eye out if this still happens |

Since Ardour 6.6 I completely switched to another DAW. I cannot test this bug. |
