It would also be useful to have a way to view and edit the raw individual MIDI event messages of a MIDI clip (in a grid list editor, perhaps).
I don't know if it matters, but I was using the latest 64-bit Tracktion 6 public beta (6.0.23) for Windows. The edit I was using was the default edit that gets created for a new project (i.e. I did not read in a project that was created in a previous version of Tracktion).
