Sale price$99.99 USD Regular price$145.00 USD

The Yamaha PSS-A50 is a high-quality mini-keyboard inherited from the Yamaha reface series. The reface series is highly regarded by professionals for its outstanding touch, feel and expressive power. The PSS-A50 runs on four AA batteries or a USB mobile battery making it easy to take on road trips, jam sessions or even the recording studio. The included USB power cable also lets you plug into a computer or AC outlet.

Tools to Inspire and Capture the Moment

The PSS-A50 packs pro-level features, sounds and effects—like Motion Effect—in a small body. Its built-in arpeggiator can inspire new ideas, allowing you to create phrases and rhythms at the touch of a key. To help you capture the magic, use the PSS-A50’s Phrase Recorder to loop, playback and record.

Anytime, Anywhere

You can connect the Yamaha PSS-A50 to a home recording setup or a mobile device. Or, when you want to step inside your music and not be distracted by the outside world, simply plug in your favorite pair of headphones. This automatically disables the built-in speaker, giving you the privacy you need.
