Casio unveils the Privia PX-S1100, which replaces its award-winning PX-S1000 digital piano. The new iteration retains most of its predecessor’s features, whilst improving the overall sound quality and expanding the product’s connectivity.

Casio’s Privia brand (designated PX) was launched almost 20 years ago as a portable digital piano range. Capitalising on Casio’s extensive distribution and marketing network, they quickly became extremely popular. Privia instruments offer excellent sound quality in a highly compact and portable package.

The Casio PX-S1000 first appeared in January 2019 at the winter NAMM show. Many said that this instrument was a “game changer”. It was slim, portable (battery/mains powered), looked and sounded great, and was extremely affordable. It could be used both at home as a family instrument, or on stage / in the studio as a “musician’s” piano. No wonder it won the prestigious Red Dot Design award in 2020.

Now Casio has upgraded the PX-S1000 and launched the PX-S1100. The new model retains the original’s elegant design. The piano’s dimensions are the same—with a depth of just 23.2cm (9.1ins) it is still the slimmest 88-note digital piano in the world. And the smart, minimalist control panel, with illuminating touch controls and gold-lettering, remains.

Casio state that by addressing the built-in speakers’ structure the sound quality has been improved. Strengthening the diaphragm has made the tone clearer, richer and more open.

The digital piano has a weighted action, balanced so that it is subtly heavier in the bass end, and becoming lighter as the player ascends towards the treble.

A.i.R. Sound Source

The Casio PX-S1100 uses its Multi-Dimensional Morphing A.i.R. (Acoustic and Intelligent Resonator) engine as its digital sound source. This technology has served Casio well over the years and is used not just for the Privia series, but also for Casio’s Celviano range of console digital pianos.

The A.i.R. processor uses grand piano samples recorded at four dynamic levels. These are intelligently processed, using a technique called “linear morphing” to deliver grand piano sounds covering the full dynamic range with seamless transitions between levels. It also delivers notes with long natural decays and impressive expression. To further enhance the grand piano experience, A.i.R. adds realism by simulating the sound of the open strings when the dampers are raised by the pedal.

Another area of improvement relates to the piano’s connectivity. The PX-S1100 comes with a WU-BT10 Bluetooth MIDI and audio adapter. This lets you connect wirelessly to your favourite devices with no extra power supply needed. You can play along with your favorite music through the PX-S1100’s powerful stereo speaker system, or link to a whole world of Bluetooth LE-compatible MIDI devices and software.

Casio PX-S3100

Casio will also shortly be releasing the Privia PX-S3100 which will be an update to the PX-S3000. This will initially appear in Japan and certain Far-East territories before release around the world.

The piano’s upgrades will be in line with those detailed for the PX-S1100. The PX-S3100 has most of the features of the PX-S1100, but has 700 onboard Tones (rather than 18), and also features an auto-accompaniment section. The PX-S3100 will initially only be available in black.
