If you perceive any unexpected behavior from your Korg B2+/B2+SP
Digital Piano, please see if this guide addresses your concern. If not, or if
the problem persists, contact your nearest Korg distributor.
If the power is left on for 20 minutes or more without the keyboard
being played, the auto power-off function will turn off the B2+/B2+SP
automatically. To use the B2+/B2+SP, press the power button again to
The instrument sounds in the B2+/B2+SP are created by recording
individual samples made from the actual instruments, processing them,
and combining them to achieve the desired sound. Depending on the
detail and complexity of the sound, one, two, or even three samples
may be combined to create each note. Nearly all of the sounds on the
B2+/B2+SP use two samples per note played. Due to this, the maximum
polyphony or number of notes that can sound at once (including when
the damper pedal is pressed) is 60. (Note that the Italian Concert Piano,
Italian Ballad Piano and Italian Jazz Piano sounds use three samples per
note, which brings the maximum polyphony down to 40.) However, the
stage electric piano sound has a maximum polyphony of 120 notes.
The pitch or tone of the piano sounds incorrect in some key regions
• The B2+/B2+SP’s piano sounds replicate the sound of an actual piano as
faithfully as possible. This means that in some regions of the keyboard,
you may sense that the overtones seem stronger, or that the tone or
pitch seems wrong. This reflects the acoustic nature of the original
instrument being sampled, and is not a malfunction.
• In order to produce the most natural resonance, piano sounds use a
“stretched tuning” that makes the notes of the lower range slightly
flatter than equal temperament, and the upper range slightly sharper.
This is how an acoustic piano is normally tuned by professional tuners.
