I gave up years ago. They just won't fix it. Pro Tools remains unusable for MIDI (well, not completely usable).

Reading this... I requested Avid to reopen all my cases relating to this issue. They responded it has now been escalated. Examples of cases I reported back in 2016 (!).

03106352 Separate MIDI clip (Command+E) doesn't adhere to grid Bug Logged/Known Defect 12/16/2016
03108869 MIDI loop trimming fails 12/21/2016
03106703 MIDI notes disappearing when switching MIDI track from sample- to tick-based Bug Logged/Known Defect 12/17/2016
03106464 Impossible to copy/paste/drag correct MIDI clips or selections 12/16/2016
03106431 MIDI notes randomly don't play, although visible in the clip 12/16/2016
03106402 Trimming looped MIDI clip end includes unexpected further notes 12/16/2016
03106397 MIDI range selection includes unexpected events 12/16/2016
03700600 MIDI events randomly disappearing when copying regions 5/9/2019

Will keep you posted when (if) I get any update from Avid.
