Korg has equipped the SP250 with their finest keyboard, the RH3 graded hammer action keyboard. Not only does it provide plenty of realistic resistance, the keyboard also comes with three different response curves to match any playing style. The Korg SP250 also has fully velocity-sensitive keys and a powerful sound engine that is able to produce the entire spectrum of notes based on how hard the key was struck. This is a powerful feature that not many digital keyboards have.

The SP250 is an expensive instrument. It comes with many powerful features that set it apart from the competitors, but there are still plenty of other affordable keyboards such as the Casio PX-150 that are a great option if you are on a budget. If you can afford the price tag, however, the SP250 is hard to beat. The SP250 also does not come with an extremely large amount of extra settings and features, though it does have 30 different high-quality voices for you to choose from.

Sound Quality

The SP250 has a powerful sound engine and a great piano sound, able to replicate all of the nuances you get with an actual hammer striking a string. What really sets it apart though, is the fact that its keys are able to completely detect exactly how hard they were struck and the sound engine is then able to produce a note whose tone and volume perfectly matches how hard the key was struck.

While many keyboards are able to produce a few variations in tone, the SP250 is able to replicate a full range of tones, notes and volumes, making it extremely realistic sounding. Add to this 30 different voices, most of them near the same level of quality, and the sound of the SP250 is one of the best you will find.

Key Action and Realism

The Korg RH3 graded hammer action keyboard is the best keyboard that the company has ever produced. The key action is extremely realistic, providing an increasing level of resistance as you go from higher to lower notes, just like what you would experience on an acoustic piano, as well as three different response curves to match your style of playing and hold the note for precisely the right amount of time.

Playing on the RH3 keyboard is absolutely incredible and is certainly one of the most innovative keyboards around today.

Other Features and Specifications

Other useful features of the SP250 include its dual headphone jacks that are ideal for student/teacher use, two resonating 22 watt total power speakers, selectable reverb and chorus effects, 30 on-board sounds that can be layered together, stereo outputs that allow you to connect the piano to external recording or speaker systems, MIDI connectivity, and a folding stand that also houses the piano’s sustain pedal.

Final Thoughts

The SP250 has a sound quality and key action that is practically unrivaled among digital keyboards. The innovations that have gone into making this piano feel and sound just like a quality acoustic are astounding, making it a real pleasure to play. At 71 pounds, the SP250 is not extremely portable, but it is compact enough to be transported should the need arise. If you are looking for a keyboard that is equipped with the finest key action and sound quality you can find then the SP250 is a great digital piano to purchase.
