As I was having a problem with imported markers, I found this thread: Need to correct markers after midi import
Now I understand why they moved when I changed tempo marks, but for my purposes I don’t need a timecode at all. Is it possible to import them as text-only?
Not directly when importing the MIDI file, but having imported it once, import it a second time via File > Import > Tempo Track, and in that dialog you can choose to import markers as system-attached text items. Importing the tempo track to the flow created by importing the MIDI file previously shouldn’t upset anything else that has been imported.
Thanks Daniel
