The Casio PX-5S is a truly portable, 88-key electronic keyboard that weighs in at under 25 pounds. Casio has kept the PX-5S affordable and light by cutting back on a few features, but the playability, sounds, and programability are still impressive. Anyone looking for keyboard with solid fundamentals, yet still easy to move around, the PX-5S is definitely worth a look. This is one of those instruments suitable for beginners and professionals alike.

As with other Privias, the button banks are to the left and right of the center LCD screen. The sound shaping options are incredible for a keyboard at this price point. Four knobs, six sliders, pitch-bend, and modulation are all to your left and serve to control the DSP and filter parameters.

To the right, the surface is textured and designed to keep your iPad from finding its way to the floor. Under this rubberized surface is the battery compartment; the unit can operate for roughly four hours on battery power alone. A USB port is present for recording and playing your music.

On the back, a stereo mini-jack input, power input, quarter-inch stereo output, and MIDI In, Out, and Thru can be found. There are also two inputs for footpedals. Finally, a pair of quarter-inch inputs are also present.

If you’re familiar with the PX-350, the same keys and scaled hammer action are found in the PX-5S. However, the PX-5S has much greater dynamic expression.


You can have up to 720 tones. 350 are slotted for you own creations; there are also 100 stage settings. The default grand piano sound is exceptional. The PX-5S has sympathetic resonance, reverb, release velocity sensors, and 4-band EQ. Lid position can also be simulated. The acoustic and electric pianos sound great and soulful. With so many sounds available, any musician would be pleased.


High-level sound editing can be done the the Data-Editor PX-5S and includes 18 pages of controls. The software can be downloaded for free from Casio. There are 6 synth layers, and the full parameter strips can be viewed with the software. While the onboard arpeggiator has 100 patterns, you can program up to 100 more. Each key on the keyboard can have its own unique setting! Try finding another keyboard with the sound shaping features found in the PX-5S at the same price.


There’s no input for an expression pedal. It’s also lacking a split button; however, splits can be programmed. A music stand isn’t included, either. While editing can be done without the software, it does make it more challenging. A few of the organ sounds aren’t anything to write home about. There are few negatives to report, and these won’t apply to many users.


Anyone in the market for a great digital piano, and requires a strong synth engine, would be pleased with the Casio PX-5S. The ability to edit so deeply is impressive for such a light and inexpensive keyboard. It’s similar to the PX-350 with added DSP and programming capabilities. Whether you’re an amateur or professional, you’re likely to be impressed. Try the Casio PX-5S before making any other keyboard purchase. If you do purchase this model, be sure to pick up the free software in order to realize all the capabilities built into this unit.

    Piano sounds are great on this keyboard and so are synth patches. Brass and guitar patches are not as great but still usable. Overall great choice if you want that acoustic piano sound. This is digital piano is designed for professional musicians and as such it doesn’t come with internal speakers. You have to get external speakers to be able to use it. To me it’s a plus, no keyboard sounds good through simple, under-sized, under-powered speakers.

    I really love this piano…so much so that I bought two of them! That’s right, I keep one set up in my home studio and I keep the other packed to haul to gigs. I’ve been a touring musician for over three decades and have owned many keyboards and this one is the best deal around. I love the realistic feel that the hammer action has and I LOVE to edit songs on the fly. It is super light, at 26 pounds even an aging, rock star wanna-be can haul his gear with ease. I also like that over the years this model has been improved with updates to the os and new banks of sounds and it has a facebook group for techies to go to drone on about how much they love their keys. It’s awesome!

    I thought the set up was simple and quick and once assembled everything worked as expected. I enjoy the lightweight piano, at about 25 pounds it can be moved around the house with ease and taken on trips if you choose to. The included sound samples are more than adequate, really good quality. Be sure to use good headphones as you can tell a difference in the sound if you use cheap ones. Also the built in speakers aren’t that powerful so if you are playing for others they will appreciate you using a keyboard amplifier. I think this is a great instrument but the amplifier is a must to really appreciate the sounds it can produce.

    I cannot praise this keyboard enough! I have used it for a long time even gigging with it extensively. The 88 fully weighted keys are excellent. The built-in sounds are great, the strings are great, brass is usable, but the synth is really tops. Great weight for gigging, under 30 pounds actually closer to 25, I believe. It has an arpeggiator, sequencer and recorder. The midi controller is fully functional and customizable. I use it with a laptop or sound module and it’s all I need. The only downside is I still use my Casio for its superior organ sounds but if organ isn’t important you couldn’t get a better instrument. I have yet to find anything out there that can beat the functionality, sound quality and price of this keyboard.

    You could say I am a bit obsessed with my keyboards. That said I think this is the best value for a keyboard that feels like an upright or grand. The built in grand and electric piano sounds are simply wonderful. The strings are good as are the synth pads. The bass and brass are also workable as are the sequencer, arpeggiator and drums. If you need those specifically you might not be as happy. I like that it is white it makes me stand out from the crowd! I like that it’s lightweight and easy to tote to gigs. I also like that I can use batteries in it. I use it live and in the studio and use the piano settings almost exclusively. It works perfectly in that capacity and I would recommend it wholeheartedly.
