The Casio PX S1100 Digital Piano combines style with substance. A tasteful, elegant design meets with a sumptuous sound set, resulting in a digital piano that sounds as good as it looks. All-new features include Casio's proprietary Multi-Dimensional Morphing AiR Sound Source, improved speaker diaphragms and coil designs, and revolutionary wireless MIDI and audio connectivity. These cutting-edge technologies augment the digital piano experience to provide you with the freedom to fully express yourself.

Good things come in small packages. This 88-key, hammer action digital piano has an incredibly authentic, natural touch response - twinned with a meticulously modelled sound generation system which accounts for sympathetic resonances, damper noise, and key action noise. The result is an instrument which feels and sounds exactly like an acoustic grand, all whilst occupying the footprint of the world's slimmest digital piano.

Full Description

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 S1100 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 S1100 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 that 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. 

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 S1100 - and enable the Surround feature to completely fill the room with your music. You can simultaneously play the PX S1100 whilst using it as a speaker, allowing you to practice and play along live to music of your choosing.

Using the free Chordana Play for Piano app, you can wirelessly control the PX S1100 with your phone or tablet. Through this, you can adjust the tone, touch response, and metronome - and even fine tune instrument settings such as tuning frequency (Hz) and temperament type. The Chordana app is an excellent learning resource - featuring a play-along piano roll mode which visually displays upcoming notes and keeps track of your playing through wireless MIDI data. With settings for tempo adjustment, AB repeat features, and an in-built scoring system, this is a great way to make learning new pieces on the piano accessible and fun.

With the PDF score viewer, Chordana Play for Piano can display the sheet music of 60 songs in the included Music Library. You can also use it to view imported PDFs. Connecting your phone or tablet to the PX S1100 allows you to turn pages in the PDF reader using the keyboard's foot pedal, giving you a seamless playing experience, which is sure to improve your fluency.

Uniquely sleek design

The PX S1100 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 S1100 certainly makes a statement.

This compact size, combined with the PX S1100's incredibly lightweight (11.2kg), 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 four hours - and you have a digital piano that you can take anywhere.
