Professional features

The PX S3100 comes with 700 excellent tones, covering a vast range of musical genres; 200 different rhythms with an auto-accompaniment feature; a wide range of audio effects including reverbs, choruses, and 100 arpeggiator settings - and much more. A pitch bend wheel and two controller knobs make this a highly expressive and versatile instrument, and the full-dot, backlit LCD panel makes navigating the countless features of this piano effortless.

An authentic grand experience

Casio's unique Multi-Dimensional Morphing Acoustic & Intelligent Resonator (AiR) Sound Source perfectly recreates the rich sound and vivid resonance of a real grand piano. Through the painstaking modelling of the sympathetic resonances of every individual string, the PX S3100 brings you an incredibly authentic playing experience. The AiR Sound Source also uses lossless audio compression, which perfectly preserves the original sound upon playback, and allows for many compressed waveform variations - resulting in an incredibly realistic, expressive piano experience.




All 88 keys of the PX S3100 have a luxurious, comfortable feel, with a fine-grained finish providing a tactile response. For a truly authentic experience, the hammer weighting exactly matches that of a grand piano, and digital scaling simulates the way in which every key has a subtly different touch and weight. When playing repeated notes, each note has a distinct voicing, which allows you to carefully control how a note starts to ring and to dampen it again with the same note. With such detailed control and expression, you'll forget that this is a digital piano.

Powerful speakers for nuanced performances

Two large speakers project the sound of your performances with incredible fidelity. The updated speakers have had Mica - a reinforcing material which is used in many high-end audio products - incorporated into their diaphragms. This allows for richer, cleaner projection of high frequencies, and a more defined, dynamic low end. Two 8W amplifiers give the PX S3100 some serious punch at high volumes, perfectly capturing and reproducing every detail and nuance of your playing. The capabilities of these speakers are ideally matched to the expressive needs and dynamic range of a grand piano, for a flawless experience.

Wireless connectivity for unrestrained control

With the included WU-BT10 wireless adaptor, you can connect your phone, tablet, or any Bluetooth Audio device to the incredible speaker system of the PX S3100 - and enable the Surround feature to completely fill the room with your music. You can simultaneously play the PX S3100 whilst using it as a speaker, allowing you to practice and play along live to music of your choosing.




Casio Music Space

This product now works with Casio's companion app, Casio Music Space. This app will allow you to access new possibilities with your Casio product whatever your playing ability. It can be used as a learning aid with a vast library of songs which you can play along with. Each note and its duration is shown visually in a piano roll making it easy to find the right notes and see how a piece of music is written. If you're more confident with reading music then you can try out the score mode - use the inbuilt scores or import your own to play along with! Page turns can be done with a pedal so you can focus entirely on your reading and playing.






A live concert simulator will simulate the reverb of a real concert space with several different settings to make you feel like you're performing in a wide variety of concert venues. You can also now access your digital piano or keyboard's settings quickly and easily with the app. No more remembering key and button combinations to alter settings - you can now change them in an easy to use and visual menu included in Casio Music Space. This app is available for free and more information can be found here.

Uniquely sleek design

The PX S3100 is the world's slimmest 88-key hammer action digital piano. It has a depth of only 232mm, and its minimalist design has been crafted to match a range of room sizes and interiors. With an elegant, mirror-like top panel, sleek touch controls, and a stylish one-tone colour design, the PX S3100 certainly makes a statement. Casio's unique high-density technology - consisting of a carefully miniaturised hammer-action mechanism, a vertically mounted circuit-board, and oval-shaped low-profile speakers - makes it possible to have a digital piano of this size with no compromise on quality.




This compact size, combined with the PX S3100's incredibly light weight (11.4kg), makes this a highly portable digital piano. Include the fact that you can run this piano on batteries - with a continuous battery life of up to two hours - and you have a digital piano that you can take anywhere.

Delivering your new piano

How are you going to get your new instrument home? Digital pianos are supplied to us flat-packed in boxes and we offer a number of options for you:

Collect from our loading bay

Our Newcastle store has a vehicle loading bay outside. At the checkout, simply select ‘in-store collection’ and we will contact you with directions to the collection point.

A note on box sizes: All digital piano collections will require the back seats of a car to be folded down. Portable stage pianos fit relatively easily in most cars. Small cabinet pianos also fit in most cars. Larger digital pianos generally come in one big box that can be up to 100kg. These pianos would only fit in larger cars and small vans. 

Box dropoff

This is our default delivery option. When we deliver boxed items we will use DHL, our own driver, or occasionally a specialist piano mover (Griffin Transport UK).

If you choose this option for delivery, please be aware that this is a ground floor delivery service only and where possible the box will be delivered inside the ground floor of the house. If there are stairs up to the front door, or if you live in a flat, it is at the delivery driver’s discretion as to whether they can help bring the box inside the front door. Ultimately, the responsibility lies with the customer in this instance to bring the piano into the address. If you want to house the piano in an upstairs room, the driver will not carry the box upstairs for you, the responsibility for moving the piano inside the house remains with the customer.

Boxed digital pianos can range in weight from 12kg to over 100kg. There are some models of piano that are either too bulky or too heavy to delivery via a drop off service. Delivery options for these pianos are restricted to a specialist installation to ensure the safe arrival of the item.

If you have any questions about our box drop off service or would like any advice regarding how best to deliver your piano please give us a call on 0191 2602915.

Premium delivery and installation

If you are buying a ‘cabinet style’ piano rather than a ‘portable’ instrument many customers feel that the best option is specialist installation. We use the services of Griffin Transport UK. This is a specialist piano removal company that we have worked with for many years, we hear nothing but great reports about the service they provide. Once you have selected your piano, we will forward your contact details to Griffin UK who will then contact you directly to arrange a mutually convenient delivery slot. They will unbox and assemble your new instrument and dispose of all packaging materials. This will give you the peace of mind that your precious instrument is handled with care and assembled correctly; the mountain of cardboard and polystyrene will also be taken care of!

Local piano deliveries are usually completed within 7 – 10 days and piano deliveries elsewhere in the UK usually within 2 – 3 weeks. 

Delivery charges

JG Windows subsidises the cost of delivery to you, ensuring you receive a quality service at a reasonable price.
