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
