Transitioning from midi accordion without previous left hand key experience, I first went with this Orla kx10 configuration..then to a korg pa500 musikant (then others) using single finger chord triggering eventually adding fingers as I did more. I don't aspire to become a pure pianist style player but to be able to use the (auto) arranger for what it was designed to do..
Am I limiting myself in what I can sound like without complete left hand technique? Probably...but am I, and my audiences happy with my sound? Yes..no other approval needed.
