It is common knowledge that the sound of a grand piano is delightful but it isn’t something that all music loving households can afford. For most music lovers, it is too expensive an affair which is why most students learning how to play the piano choose keyboards which is slightly more cost effective. But what if there was a keyboard or digital piano that sounded just like a grand piano? Sounds unrealistic but that is what Casio wants to achieve with the PX-870.
The PX-870 offers natural reproduction of the rich expressive power and resonance of an acoustic piano. Of course, it comes with many interesting features including CASIO’s newly developed Multi-Dimensional Morphing AiR Sound Source. In an acoustic piano, the sound is produced is not only that of the keys. Other strings with frequencies closely associated with those producing the sounds resonate as well. In ordinary digital pianos, this string resonance effect is reproduced virtually. The Multi-dimensional Morphing AiR Sound Source takes a different approach, however, by adopting a ‘string resonance’ system incorporating a stereo resonance simulator for all 88 keys. The resonance of the 88 keys is reproduced completely and naturally which makes you forget for a moment that you are indeed playing a digital piano and not an acoustic one. Another feature that lends to the grand piano feel is the sound system which projects sound upward and downward.
Of course, beginners and experts both will enjoy the feel of the simulated ebony and ivory keys. The smooth touch is similar to the keys of a grand piano. Another feature to look forward to is the Lid Simulator. Now with regards to a grand piano, the sound volume and quality changes when the lid is raised or lowered. The acoustic effects of opening and closing the lid are simulated in fine detail in the PX-870 by the Lid Simulator. The deep resonance resulting from the use of a damper pedal has also been reproduced naturally by a stereo resonance simulator installed on all 88 keys. The four adjustment levels namely Hall Simulator, Concert Play, Headphone Mode and Volume Sync EQ dadd to the convenience of the pianists.
The Chordana Play app just enhances the playing experience. It will allow you to control various functions on compatible devices, save all settings (4 slots), as well as sync settings between app and compatible devices. There are about 201 built-in songs which will be great for beginners. The PDF Score Viewer is another hand feature which will let you view scores for 60 songs in the music library, regular PDF files and descriptions of built-in songs. There are many other handy features as well indulging the ability to change tempo of playback, transfer song data as MIDI files and more.
