You select a chord preset
you have 4 zones (from left to right )
3 are actually populated , zone 2 is unused so i moved its zone all the way right , ain't gonna be used
Zone 1 aka Chords A alows you to actually selected a chord (a chord preset is actually a set of chord !!)
Zone 2 aka Picks A let's you play individual note of those chord , you can play note by note (good for melodies while being ion scale ) or simeply replay a chord withing the chords set (if you have for exemple a 1/3/5 chord you can play 1/5 or 3/5 without having to mess around)
Zone 3 aka Picks B is the strums !!!
