They manufactor top-of-the-line accoustic pianos (notorious for their "fall into infinity" finish)
Their electronic keyboards are outstanding - responsive to speed, pressure duration - virutally an electronin clone of one expects in a manual - and yet offering everything available (plugs/patches/studio) from the digital world.
In KEYBOARDS - manual and electronic - Yamaha of the world's five GREATS!! And held the position for over 40 years.
