Summary0007192: Splitting MIDI regions creates a mess
DescriptionWhen splitting a MIDI region between the notes, the first note after the splitting point is often removed.

This seems to depend on the distance of the splitting point from the note.

Some notes seem to be unaffected, some need a smaller distance from the splitting point to disappear, some disappear with a larger distance.

Also frequently the two new regions created during splitting overlap or leave a gap between them.

When moving these overlapping or gapped regions their contents seem to jump to different locations within the regions sometimes.
Steps To Reproduce1. Record a region with a lot of short notes on a MIDI track
2. Split the region multiple times between the notes (using the S key)
Additional InformationI've captured a short video that demonstrates what I experience:

The newest version of Ardour where I experienced this is:

Ardour 5.5.72
"The Plateaux of Mirror"
(rev 5.5-72-ge97404c)

Wow, I didn't notice that I had magnetic snapping on at all. Good I recorded a video.

this should be fixed in current master (rework_snap branch was just merged).

I just retested this with 5.6.171 and still seems to be resolved, so marking as such. If reporter thinks otherwise they can reopen.
