The new digital piano Casio Privia PX S1000 is a very stylish instrument.
The first thing that strikes you is its ultramodern design.
Glossy surface, sensory buttons that are not visible when the instrument is switched off, ability to connect audio via blue tooth, ability to control and switch over (toggle) through functions and sounds through a special free app, (Chordana Play for Piano). All this is very impressive.
Secondly the PX S has one of the most powerful and realistic sounds that I had ever heard from digital pianos. Deep bass, saturated acoustic overtones and resonance.
The beauty of this instrument that it can be absolutely autonomous, used without mains power. It can be powered by batteries. While it is working on battery power you can also connect a separate unit with three pedals even without the branded stand!
It is very important for me for my concert performances. You can use an ordinary X-shaped stand and at the same time to have in the arsenal three pedals.
Well, let’s listen how its sounds.
