Overview
The Yamaha PSR-E323 is an entry-level home electronic keyboard dedicated for beginner, learning and personal usage. It is positioned in the low-end class, competing with similar products such as Casio LK-220 and CTK-3000.

Like most electronic keyboards in general, the PSR-E323 is compatible with MIDI standard, with an integrated MIDI input/output jacks for connecting to a computer or other electronic instruments.
Sound engine
The keyboard contains a scaled-down version of Yamaha's Advanced Wave Memory (AWM) tone generation system, which is a PCM sample-based synthesis engine. The samples are an adaptation of Yamaha's earlier PortaTone series of home keyboards produced between 1997 and 2006, as well as the MU-series sound modules produced from 1994 to 2002.
It features a 32-note polyphony with 16-part multi-timbral support and Yamaha XG Lite sound set.
One notable feature of the keyboard is "Portable Grand", a function that instantly sets the keyboard to a stereo-sampled piano sound. The piano are digital samples of a Yamaha grand piano dating back to the early-1990s, and was formerly used in digital pianos at the time such as YFP, YPP, and YPR series, as well as early models of Clavinova.
