The keybed makes a great impression on many who describe it as having the same playing feel as an acoustic piano. A lot of professional musicians are amazed with its sound engines showcasing a lot of variation. Each sound engine for pianos, electronic pianos, organs, analog synth and even sample based sound engines reproduce authentic and quality sounding presets. The "Set List" feature is one of the features that stood out since it allows direct access to a combination, program, or song in the sequencer to play next. Many owners also find its split, layering, velocity assignment and connectivity capabilities remarkable. Its manual also provides in depth combinations and access to parameters for more advance features.


A few users find the joystick controls to be a bit of a hassle to use and prefer a wheel-type controller.


This is an all-around versatile workstation ideal for any studio and performance setting.
