Yamaha PS500 Review: A Learning System Built Into a Piano
The PS500 is Yamaha's smart piano: 88 GHS keys with Stream Lights above every key that show which note to play and when, the CFX and Bosendorfer Imperial samples, and deep Smart Pianist integration with Audio to Score and flowkey. This review covers how the learning system works, what the listing confirms, and whether the premium over a conventional portable is justified.
Our Verdict
Research Score 78/100The Yamaha PS500 is the piano to buy if you want to teach yourself songs you already know and you learn best by following lights. Stream Lights, Audio to Score and the flowkey integration are a complete self-study system on top of two concert grand samples. The GHS action is the compromise at this price; a pianist who does not need the lights gets a far better keyboard in the P-525 for similar money.

What Makes the PS500 Different
Above each of the 88 keys sit four LEDs. As a song plays, the lights step down toward the key to show when the note is due, so the player follows the lights rather than reading notation. Yamaha calls it Stream Lights, and it works with built-in songs, MIDI files and, through Smart Pianist's Audio to Score, with songs from a phone's music library that the app converts into a piano score. The listing also confirms flowkey integration, the CFX and Bosendorfer Imperial samples, and an FC4A piano-style pedal in the box.
The PS500 is priced like a flagship portable, and the learning system is the reason.
Action
The PS500 uses GHS, Yamaha's entry graded hammer action, which is a sensible teaching keyboard and a surprising choice at this price. It is lighter than the GHC in the P-225 and far behind the wooden GrandTouch-S in the P-525. For a self-taught adult or a child the GHS is adequate; for a pianist who already plays, it is the reason to look elsewhere.
Sound
Two concert grands, the bright Yamaha CFX and the darker Bosendorfer Imperial, give the PS500 the same pair of flagship samples as the P-525, which is a strong foundation. The listing does not publish polyphony, the voice count or speaker wattage; Yamaha's specification should be checked for those before relying on them. Through headphones the two grands are excellent and the Stream Lights are visible without looking down.
Smart Pianist and Apps
Smart Pianist on a tablet controls the piano, hosts the song library and runs Audio to Score. The flowkey app adds structured lessons with feedback that the piano's lights can follow. The listing does not confirm Bluetooth; connection over the USB to Host port with a cable is documented, so plan on a cable unless Yamaha's specification confirms wireless.
Setup and Weight
At about 48 pounds the PS500 is as heavy as the P-525 and needs a sturdy stand. The FC4A piano-style pedal in the box is a better accessory than the footswitches bundled with most portables. Yamaha's matching stand and three-pedal unit are optional.
PS500 Against the Alternatives
Against the Yamaha P-525, the P-525 has the wooden GrandTouch-S action, VRM, binaural sampling and documented 256-note polyphony for similar money, without the lights. Against the P-225, the P-225 is lighter and cheaper with the newer GHC action; the PS500 adds the Bosendorfer and the learning system. Against a Roland FP-30X plus a lesson app subscription, the Roland has the better action and the app provides feedback on a screen rather than lights on the keys.
Buy the PS500 only if Stream Lights and Audio to Score are the way you want to learn.
How a Practice Session Works
A typical PS500 session starts in Smart Pianist: pick a song from the built-in library, a MIDI file or an Audio to Score conversion of a track in your phone, choose a hand to practice, slow the tempo and start. The lights above the keys count in, step down toward each note and hold while it sounds, and a wrong note simply waits for the right one. The piano's own tempo control and metronome keep the exercise honest, and the two concert grands make even a halting first pass sound good. It is a system that rewards daily use more than occasional practice.
Who Keeps It
Adults who learn songs by ear and lights, and families with children who respond to guided practice, use the PS500 daily and value it. Players who progress to reading notation and technique tend to want a better action, at which point the lights stop mattering. It is a learning instrument first and a piano second, and it should be bought as such.
