Review Summary:

If I were to recommend a digital piano to someone who’d prefer an acoustic piano, this would be the one. The piano voices are amazing and realistic, it comes with a stand and sustain pedal, and its speakers are quality.

Keys & “Action”:

The keyboard features hammer-action weighted keys, with a heavier touch in the bass octaves. The keys themselves are full-sized, and feel surprisingly realistic (think baby grand keys – a wee bit lighter than those of an older full grand, but still have a solid touch) … definitely not a disappointment in this area.

The controls are straightforward and right on the front panel; although, like most models, a peek in the instruction manual is necessary to execute advanced functions such as layering and splitting.

Voices & Touch-Sensitivity:

There are 30 pretty realistic-sounding voices. I found the pianos, harpsichord, strings, and organs to be particularly pleasant; only a couple of the electric pianos and choirs came off as a bit artificial.

* When layering (allowing two tones to play simultaneously on one key), you may not use voices that are controlled by the same button. For example, the harpsichord voice is selected using the same button as the clavichord, so these two tones may not be layered together.

Available tones are:

  • 5 Pianos; including a full-sounding grand, a bright upright, and a honky-tonk
  • 7 Electric pianos
  • 3 Pipe organs
  • 3 Jazz organs
  • 3 Strings
  • 3 Choirs
  • 2 Clavichords; including one funky clav with wah effect
  • Harpsichord
  • Vibraphone
  • Marimba
  • Acoustic guitar

Touch-sensitivity may be adjusted with 3 preset velocity curves.

Preset Songs:

The SP250 contains 30 demo songs (abridged versions of a some classics and a few Korg originals); one song per voice for sampling.

Keyboard Speakers & Quality:

The two 10 centimeter, 11 watters sound great, even at full volume; no rattling or fuzzing in the lowest or highest octaves. Speakers switch off automatically when the headset input jack is occupied – whether by headphones or an external amp – to avoid feedback or interference.

Included Accessories:

  • Sustain pedal with half-pedal effect
  • 12V AC adaptor
  • Matching, removable sheet music rest
  • Keyboard stand with three pedal unit rest

A bundle package is available for $700, and includes a piano bench, a matching keyboard stand, and stereo headphones.

Back Panel:

○ Two headphones/OUT, 1/4" 
○ MIDI in/out
○ Pedal input, 1/4"
