Using iRP for iOS on iPad here.

Q: What is the intended output of the Harmony track which is created as part of a MIDI Export?

My observation here is that the Harmony track is always blank. Is there something I can do to change that? Is it a placeholder for future use?

FWIW, I would very much like to see iRP export a track that consists solely of block chords, one for each chord change on the lead sheet. This would be in contrast (in addition to) the as-played performance MIDI which is exported now. This is actually what I would have expected the Harmony track to be, but as I say, it's blank here.
