Hello - Exporting to Ableton is not working properly. Notes are missing and/or chords are inverted. I'm not sure if it matters but I've tried using Safari and Chrome with similar results.
The harmony track export from Hookpad will consist of the notes that Hookpad uses for its own playback. Taken alone, these chords may appear to be inverted, but when taken with the bass track, should have the correct inversion. Hookpad also uses standard 3-note right hand voicing, so chords like 11th chords will only contain root, 7th, 9th, 11th, and 9th chords will contain root, 3rd, 7th, 9th.
In the next version of Hookpad, we're planning on allowing you to choose the complexity of the voicing, in case you'd like to add additional notes in these extended chords.
