I’m in the honeymoon period so my like to this controller is heavily biased.
Do you have maschine, Mpc studio, or cubase? They all have some sort of good chords and scales mode built in too.
If you don’t want to learn theory and just want something to play against that is what I use as my session player for I strummers, even when I fail with this I can always fall back on those three options.
