About Casio
Casio began as Kashio Seisakujo, founded in Mitaka, Tokyo in April 1946. Casio Computer Co., Ltd. was established in June 1957 with Shigeru Kashio as its president, and the company is headquartered in Shibuya, Tokyo.
Casio's corporate site lists electronic musical instruments, under the heading Sound, as one of its business areas alongside timepieces, education and label printers. On casio.com the digital piano and keyboard range is organized into the Privia, Celviano and Casiotone lines, with categories that include stage pianos, portable keyboards, lighted key keyboards, console pianos and hybrid pianos. The three instruments featured here are the CDP-S160, the Privia PX-770 and the Privia PX-S3100.

Why we recognized Casio
The House of Octave Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose gear consistently stands out in our player-tested category guides. Casio earned it on the strength of the products below, judged the same way every product on this site is: assessed on build, tone, and playability, weighed against what players actually report over years of use, and ranked on merit.
Casio gear we rated highly
Casio CDP-S160 88-Key Weighted Digital Piano
One of House of Octave's top digital piano picks for anyone who needs the instrument to move or share a room. It pairs an 88-key scaled hammer action keyboard, with simulated ivory and ebony key surfaces, with a chassis that weighs 23.2 pounds and stands 3.9 inches tall. It runs on six AA batteries as well as the included AC adaptor, so it can be played away from an outlet, and Duet mode splits the keyboard for lessons.

Casio Privia PX-770 88-Key Weighted Console Digital Piano
One of House of Octave's top digital piano picks for a piano that lives permanently in one room. It is a console with a furniture cabinet, a sliding key cover and three built-in pedals including sostenuto. The Tri-Sensor II hammer action reads each key at three points, which is what makes fast repeated notes speak reliably. Duet mode splits the keyboard for lessons, and there are two headphone jacks.

Casio Privia PX-S3100 88-Key Weighted Digital Piano
One of House of Octave's top digital piano picks for players who gig or write. The WU-BT10 wireless adapter ships in the box, so Bluetooth MIDI and audio work on arrival. The controls are illuminated touch panels on a gloss top panel, and the piano voice is a German concert grand sample with string and damper resonance. Two hundred rhythms and onboard recorders make it a writing tool as well as a practice instrument.
