The Outer Design of the PX- 870
This PX-870 is not a lightweight model and is not designed for carrying out of your home frequently for your performances. It is a furniture style piano that weighs about 75 pounds with three-pedal systems. But it stays compact and takes very little space in your living room. It features a stylish design and adapts to all home environments. The parts of this piano do not come pre-assembled, but you can easily fix them by reading the manual and spending an hour of your time.
The cabinet is smaller in height and has fewer seams, thanks to the improvisations from Casio. It features a nice wooden texture as it is made up of fiberboard pressed wood. There is a narrow speaker grill, a projection of the improvised speaker system, on par with the opened lid of the acoustic pianos. There are three pedals at the bottom of the cabinet, for sustain, soft and sostenuto and the sustain pedal supports half-pedal action as well.
The keys are protected from dust with the help of the pull-out keyboard cover. The piano is available in both white and black finishes. The entire control panel exists at the left end of the piano, rendering it a neat and uncluttered look. There are just eight buttons for the sounds and functions and you can access a number of functions with key+function action. There is no display and you only get a beep sound when to change the functions.
The Keys – From Where the Magic Begins
As we know, the entire Privia series from Casio features the tri-sensor hammer action keyboard in the scaled fashion. The 88 full-sized keys make use of actual hammers so as to recreate the feel of the acoustic piano. Their triple sensor detection system helps with a responsive playing experience with a faster repetition of notes. The graded keyboard is touch-sensitive with three preset settings to choose from. The keys have ebony and ivory texturing on top of them to prevent sweaty fingers from spoiling the notes.
The Piano Sounds and its Effects
With the PX-870 you can be sure of some high-quality sound, as it makes use of the AiR sound source multi-dimensional morphing technology. It will help professional pianist and music composers with rich sound at excellent accuracy with its lossless audio compression feature. Also, the PX-870 features a four-layer piano tone that is smooth, rich, and natural.
This piano features about 19 built-in songs that pertains to grand pianos, electric pianos, organs, harpsichords, strings, bass, vibraphone, etc. It makes use of the string resonance system that helps in simulating resonance for each of its 88 keys. The pianist is also able to adjust the string resonance according to their taste with the four settings available, pertaining to sound suppression and reverberation.
Yet another unique feature of this piano is the lid simulator, which alters sounds associated with the lid opening and closing of the grand acoustic pianos. One important feature that is available only with the PX-870 is the Key off simulator. This function helps in altering the tone of the piano sound based on how fast the fingers manipulate the keys. Thus, slower key release products longer reverberation and vice versa.
The pianist can also customize the hammer response setting to define the time deviation between the keypress and the actual sound. With the help of the hall simulator functionality, you can recreate the acoustics of different performance venues such as a standard hall, French cathedral, auditorium, etc.
The PX 870 has a 256 note polyphony, which is great for a piano of this price range. You can easily attempt even the complex of music pieces with this polyphony range. The piano has a 40W sound projection system with the help of its four speakers. The sound comes from different angles in its piano, and it sounds as loud as the acoustic pianos, with a realistic experience. You can easily fill a medium-sized hall with quality music without accessing any external speakers.
