Summary0009207: Splitting more than two midi regions (with control data and at the same playhead position) renders project unrecoverable
DescriptionI have three midi tracks, each with control data tracks. I found a region I wanted to copy and paste to repeat. I had serious issues doing this (see my bug report from earlier today - 24th January 2023 - link below) so I thought I might be able to achieve what I wanted by splitting each track at the start region point and the end region point. Every time I did this I could copy and paste the region once or twice before the project crashed. If I pasted the copied region just once and saved it, closed Ardour and tried to reopen the project Ardour would hang at the screen grab supplied.
I repeated this process many times and the found the fault to be consistent.
In order to narrow down the failure point I decided I would save the project at each of the six split points, save the project and try and reopen it. I was able to re open the project twice (after the first and second splits). The screen grabs are:-
1) Snip 1 (before project saved and reopened successfully)
2) Pre snip 2
3) Snip 2 (before project saved and reopened successfully)
4) Pre snip 3
4) Snip 3 (before project saved and could no longer be opened)

I'll try again to upload the screen shots. I'm on holiday in a rural area at the moment and the internet isn't great...

Update: I have successfully split three midi tracks in two places each - containing ten automation tracks between them. The project could then be successfully saved and reloaded. The difference between this case and the case in which saving the project after the total six track splits (or, more likely, I think - any split in a third track), saving the project and the project being unrecoverable appears to be the eight further automation tracks (all of the automation associated with the third midi track) being cleared. This suggests to me that there is a tipping point somewhere between a total of ten and eighteen automation tracks in my setup.
