KORG has a long history of building high quality digital pianos. Here, in 2025, they have nineteen distinct models (of which some have colour, finish and feature variations) across four distinct ranges.
Here we take a look at the main similarities and differences between ranges, as well as discussing the difference in models within each range.
To keep things fairly simple, this is an overview article. We have specification pages and comparison tools for these instruments which are linked below.
KORG Ranges
KORG currently divides its digital pianos into four distinct ranges which tend to give an indication of how KORG imagines the instruments will be used. That said, there is significant crossover between ranges, and variance of specifications within each range.
The largest range is the CONCERT series, in late 2025 it comprises of eleven named models, with some additional variations.
The range simply named Digital Pianos has four distinct models, though one in particular has several colour options.
Finally, two models each reside in the Digital Ensemble and Performance ranges.
This specification comparison covers fifteen of the models shown above. The SP versions are not linked as they have the same specifications as their non-SP versions. The link offers further direct comparison of primary features and specifications.
SP Models
Within the ranges are four models ending in the “SP” label. These are identical to the non-SP version with the same name/number, but are sold complete with a stand and a three pedal unit. All other specifications are the same, and the base model can be upgraded from a single pedal unit if desired.
The four models this applies to are the B2+/B2+SP, B2/B2SP, B1/B1SP, and XE20/XE20SP.
Main Features
Keyboard Type
Every digital piano across the ranges has full size piano-style keys. Every model has an 88 key version. The SV-2 also features a 73 key variant.
All have full touch sensitivity, none has aftertouch. The keys are fully weighted, with the exception of the B2N and the Liano which have semi-weighted keys.
Polyphony
All CONCERT digital pianos have 120 notes of polyphony, as do those in the Digital Piano category. The XE20/XE20SP have 184 notes of polyphony, while the two Performance pianos have 128 notes.
Number of Sounds
CONCERT digital piano number of sounds range from 8 to 32. The Digital Pianos generally have 30, excepting the Liano which has 8. Those in the Digital Ensemble category have 700+. The Performance couple have 700 (Grandstage X) or 72 (SV-2).
In relation to the replication of acoustic pianos, the instruments vary in the type of sound technology employed, together with how many different acoustic instruments are available.

Year of Launch
The original launch date of KORG’s digital pianos range significantly, from 2013 through to 2025. The majority were released on or after 2020.

Price
Original retail price varies considerably, even within ranges, from $299 up to $2,999. Some of the older models in particular can be bought on the second hand market for considerably less, and new models often see discounts from certain retailers.
Conclusions
Any of the digital pianos in these ranges will offer a quality playing experience. The main difference between the less and more expensive instruments comes down to the technology used in sound reproduction, and general materials used and build quality.
Higher end models will generally give a more realistic playing experience modelled on an acoustic piano, whereas less expensive models are more entry-level instruments aimed at learners and beginners, for whom spending four figures is too much.
