About This Model

The Yamaha PSS-790 is a late-1980s/early-1990s portable keyboard built around Yamaha's Advanced Wave Memory (AWM) sound engine, delivering 100 voices with up to 28 notes of polyphony. Its 61 mini keys are non-weighted and velocity-insensitive, keeping the layout accessible and lightweight. An 8-track onboard sequencer and around 49–50 accompaniment styles make it a capable self-contained arranger, while a pitch bend wheel and vector synthesis joystick add expressive control uncommon at this tier. Connectivity includes MIDI In/Out/Thru alongside a headphone jack and audio output, and the keyboard runs on both AC and battery power with built-in speakers for standalone use.

A great opportunity to own a Yamaha PSS-790 at this price point.
