There are various utilities on the web for converting midi to and from text formats, e.g. http://www.archduke.org/midi/ You could have a potential workflow as follows: - convert Lilypond's MIDI output to text - edit as necessary - save diff of the edit - convert back to MIDI for playback ... - edit Lilypond, export new MIDI, convert to text - use patch to apply previous diff - convert back to MIDI for playback https://www.pair.com/support/kb/paircloud-diff-and-patch/ -- Mark Knoop
