I am a long time user of Logic and I know that it was a chord track a long time ago but that chord track don’t had much similarity with Cubase and Studio one chord track today. I think we should do an opinion for a chord track in Logic. There are many App out now that have chord as main work tool, like Synfire, Scaler, InstaChord, Ez key etc. You can easy drag midi file into Logic but with no Chord names but after that in Cubase you can easy copy and generate more track with the same chord. You can also make a little riff and or melody in one bar, copy to four or how many different cord you have and choose make cord. Once you have transpose all riff the to respective chords. Easy and quick workflow!
