Sorry, one more:
5) Is there a good reason why chords can not be entered straight from midi controller, is there a way to bypass "CTRl+Enter" when entering them from controller?
You could use midi to qwerty (see Tips n Tricks) to send Ctrl+Enter (and <L R>) from an assigned midi key, or AHK to send it with the middle mouse button.
I could probably add that to the chord picker tool with AHK as there is some MIDI IN support.
How would you need it to work ?
