We say :

Roland's FP-30X is the new, improved version of their fabulous FP-30. This piano provides wonderful sounds, great feel, and ultimate portability should you require an instrument for use in the classroom, practice room or school hall. You can add a KSC-70 stand and a KPD-70 three-pedal unit to give the piano a cabinet-style look if required. Our students learn quickly with this natural and expressive portable keyboard! We know that yours will too. 

Roland say : 

When quality counts but budget is a factor, the FP-30X is the sweet spot of Roland’s FP-X series. Balancing affordability with superior performance, this slim and stylish portable piano builds on the entry-level FP-10 with an enhanced sound engine, more powerful onboard speakers, and increased polyphony. Featuring Roland’s SuperNATURAL Piano technology and the same expressive 88-note PHA-4 Standard keyboard as the premium FP-60X, the FP-30X is the perfect home instrument for seasoned players. And with its easy-to-transport weight and Bluetooth connectivity for lessons and play-along audio, it’s an ideal choice for any pianist who wants to develop their skills or perform at small events.
