I just found out that the chord buttons store the exact note/key configuration. So even when the button says plan [A min], it actually contains the precise voicing and keys pressed when detected (or as it came from one of the suggestion menus). That’s awesome, I like it!
Now it would be super useful if there would be an indication on the chord button what voicing it represents. For example, I played around with different voicings in the scale menu, and then dragged over the different variations of voicing [A min].
But now I can’t tell which is which (until I click on it). I suppose hovering shows the actual piano keys involve, perhaps that’s good enough.
