This article is from the Digital Pianos Specifications FAQ, by Isako Hoshino firstname.lastname@example.org.
Following is a list of technical specifications of various digital
piano make and models. Specifications may change without notice.
An attempt was made to list the models from low- to high-end order
within the given manufacturer and series. If you find any error
or have updated information please contact the FAQ maintainer at
the end of this list. The word "Preliminary" means that the
information is based on a pre-release information.
Pricing information was intentionally omitted because:
(1) retail prices are useless, since digital pianos are never
sold at that price, and
(2) there is a new and used gear price lists maintained
by Casey Palowitch and Neil Bradley.
If you want pricing information, I highly suggest you to check out
the New and Used Gear Price List at the following WWW URLs, and
also, urge you to participate in keeping them up to date.
