Enjoy your KMA Hammer. I’ve had one for two weeks now and really like it. No problems playing standard LH chords, RH melody for popular music on it. I see it as a useful tool (not a toy) for certain situations like casual get togethers, air travel, or any occasion where set up/load in maybe complicated by stairs, tight space, or transportation issues. Ever try to get a Tyros in a flight case into a small Mexican cab? Not recommended…
