Korg built the B2 around accessibility, and it shows in the short control list: power, volume, piano play, sound and metronome. The 88-key Natural Weighted Hammer Action is heavier in the low register and lighter in the high register, with three touch settings. Korg lists 12 sounds, five of them pianos from a new engine, including German and Italian concert grands, plus electric piano, organ, harpsichord and strings. Connections include USB MIDI and audio, an audio input and a combined headphone and line output, and the 15 W x 2 amplifier is stronger than the P-145BT's. A damper pedal and music stand come in the box, along with access to the KORG Software Bundle. The weak spots: polyphony tops out at 120 voices, half-pedaling needs the optional PU-2, and Korg's spec sheet lists no Bluetooth. Korg's US page shows no price, so we scored value conservatively. We compared documented features and published prices; we did not test it.
