Description
The Yamaha PSS-A50 packs expressive playing and creative features into an exceptionally compact 37-key keyboard.
Its high-quality touch-sensitive mini keyboard is derived from Yamaha’s acclaimed Reface series, giving the PSS-A50 a much more responsive playing experience than you might expect from such a small instrument. Whether you're practising, creating ideas or working with music software, it's an extremely portable way to keep making music wherever you are.
With 42 instrument voices, 138 arpeggio types, a phrase recorder and Yamaha's Motion Effect function, there's plenty here for experimenting with melodies, rhythms and new musical ideas. USB-MIDI connectivity also makes it easy to integrate the PSS-A50 with a computer-based music setup.

Who Is This For?
The PSS-A50 is a great choice for musicians who want something genuinely portable without giving up touch sensitivity and creative control.
It's particularly well suited to travelling musicians, students, songwriters and producers looking for a small MIDI keyboard that can also operate independently with its own sounds and speaker.
Expressive Mini Keyboard
Despite its compact dimensions, the PSS-A50 uses Yamaha's high-quality 37-key mini keyboard with Touch Response.
The action is derived from the keyboard design used in Yamaha's Reface instruments, giving you control over dynamics and expression while keeping the instrument small enough to take virtually anywhere.
Creative Arpeggiator & Phrase Recorder
The built-in arpeggiator offers 138 different types, making it easy to turn simple chords and notes into more elaborate musical patterns.
A phrase recorder lets you capture, play back and loop your ideas, while the Arpeggio Hold function makes it easy to develop patterns and experiment with arrangements.
Motion Effect
Motion Effect gives you 34 instant effects for transforming the sound while you play.
Combined with the arpeggiator and phrase recorder, this gives the PSS-A50 considerably more creative potential than a conventional mini keyboard and makes it particularly enjoyable for experimenting with electronic sounds and musical ideas.

Connect to Your Computer
USB-MIDI allows the PSS-A50 to connect directly to a computer for use with compatible virtual instruments, DAWs and music-production software.
That makes it useful both as a self-contained portable keyboard and as a compact touch-sensitive controller for a computer-based setup.
Made to Travel
At just 506 mm wide and approximately 1.2 kg without batteries, the PSS-A50 is genuinely easy to carry.
Power it from USB or install four AA batteries when you want to play away from a power source. There's a built-in speaker for standalone playing and a stereo mini headphone/output connection when you want to practise quietly or connect to other equipment.
