Features Of Casio Privia PX 770


Design and Look

Design Of Privia PX 770 Digital Piano

Casio Privia Series Digital Piano is known for authentic sound, feel and classy looks.

The overall body of the PX 770 is compact and looks very Elegant and Modern.

It is available in beautiful wood grain finish with 3 color (white, brown, black) options to choose from.

All of the colors leaves a classy impact and is sure going to compliment its surroundings too.

The seamless sides with the sliding key cover adds a little more sparkle to the existing beauty.

But a good looking digital piano is of no use if it fails to delivers what it claims to be. So lets look at the keys.

Keys

Ebony and Ivory Weighted Keys of Privia PX 770

Keys of Digital Pianos plays a very important role in the overall feel and resemblance of Acoustic Piano.

Luckily The Privia PX 770 does a wonderful job.

The Tri-Sensor keys offers three level of velocity sensitivity when the keys are pressed.

You can even turn it off too.

Velocity sensitive keys is a common feature but is quite a important one too to.

What it does is that it changes the magnitude of the sound according to the impact of the keypress.

Which means you will let a louder sound if you press the keys fast and mellow sound when the keys are pressed gently.

The velocity sensitive keys allows you to be more expressive while playing.

Touch sensitive keys also comes useful when you like to repeat a certain note quickly.

Like general you don't need to wait for the keys to rise to its topmost position.

Not too much years back these features are reserved only for higher end digital pianos.

But thanks to technological advancement touch responsive keys are not that exclusive any more.

The Synthetic Ebony and Ivory key tops delivers firm grip and helps in avoiding finger slips even after long hours of playing.

The 88 keys of PX 770 have Graded Hammer Action response like an Acoustic Piano.

This means the heavier keys are on the bottom end and the lighter keys are up top. 

Upon using I was really impressed with authentic touch feel of the keys.

AiR Sound Source and Damper Resonance 

AiR sound source

The Casio's AiR sound source is impressively awesome.

Acoustic Intelligent Resonator is a processor which reproduces the nuances of a concert grand piano and does it pretty well.

The technology behind AiR is known as Linear Morphing which provides seamless and runtime transitions from Piano to Fortissimo.

To produce Damper Resonance digital effect AiR simulates the resonance which occurs inside an acoustic Grand Piano when the damper pedals is used. 

As the dampers release off the strings in an acoustic grande, all the strings vibrate freely and resonate off the piano soundboard

And AiR sound source pretty well mimic the entire mechanism in digital procedure.

You can also turn the damper noise completely off.

Layering and Split Mode

Lets take this section a little short and to the point as almost most of the digital piano comes with Layering mode.

Layering Mode allows you to combine two instruments sound throughout the keyboard simultaneously.

So when you press any of the keys you will hear both the sound of the keyboard concurrently.

Split Mode comes very handy during learning sessions with teacher or other student at the same time.

What Split mode does is that it divides (splits) the keyboard in two equal part. Each side has identical pitch range with 2 Middle C's.

So you can sit along with your teacher and copy the hand movements of the teacher and try to positions them as the mentor.

It also helps to practice when sitting aside with another student too.

Split mode can also be utilized to perform two pianist at the same time.

Speakers

px 770 speakers with sound projection

Casio Privia PX 770 features 2 * 8 watt powerful speaker system.

It also has 2 more speakers placed below the keybed section of the digital piano.

The speaker placement is genius as it throws the amplified sound toward the audience and player provinding a wonderful stereo amplification system.

Apart from 4 speakers PX 770 also has 2 headphone connectivity option for private practicing.

The Dual headset connectivity allows 2 person at a time to play the keyboard via split mode.

Concert Play Feature and Songs

Concert Play Feature

My thoughts about the concert play feature is not that cool.

The concert play option provides 10 high quality symphony orchestra recording.

On the recorded orchestra performances you get the option to silent the piano playing part and play the piano part by yourself.

It will create the feel that you are performing with a live orchestra.

Built-In Songs

Privia PX 770 is also equipped with 60 Songs. With extra 10 songs capacity to add on your own.

With Built In Songs you can play along with songs in background as the concert play feature. The built in songs also comes handy for inspiration of new musics and of course of entertainment.

These little but necessary features make it one of the perfect option to consider if you want to form a solid base in playing piano.

Tones, Recording and Metronome

The Built-In two-track MIDI recorder allows you to save your performance onto the 10 slots assigned for storing the user generated songs.

One thing I was really impressed with is that its recording option allows you to record the left hand part or right hand part specifically.

Built-In Metronome

Metronome is one of the most needed feature for a budding pianist.

You simply can't understand the relation between time and sound without a metronome.

The Built-In metronome inside PX 770 allows you to adjust both, the tempo and meter. 

Tones

PX 770 comes with 19 built in Tones and 128 note polyphony.

Connectivity Options

Nowdays, Connectivity option is one of the most crucial option and devices which no longer adjust to these shift are not considered Smart.

Luckily Casio PX 770 offers a tons of connectivity options. With the Class Compliant USB Type B you can connect your PC or Mac for editing, creating music with music software.

The class compliant USB automatically detects the connecting device and does not require any additional drivers to install individually. Just plug and play.

You can also use it as a MIDI controller.

What I didn't liked is the absence of Line Out jack.

Chrodana Play App Integration

Chordana App Integration

Chordana Play App from Casio is a completely game changer add on in the Privia PX 770.

With the free Chordana play app you can tweak each and every feature of the PX 770 digital piano. The app also allows you to learn piano playing.

With the 50 Built-In Songs each with its music score really pace your learning curve and makes your learning easy and fun.

You can use the step by step lesson mode with scoring system and track your progress day by day.

The app can generate music score from MIDI files as source.

My Experience With Casio Privia PX 770

My experience with Privia PX 770

So, from my 20 days experience all I can say is that Privia PX 770 is one of most authentic feel digital piano around $700 price tag.

Scaled Hammer Action Weighted Touch Responsive Keys leaves a lasting impression when played.

The Grand Piano and other musical instrument sound is remarkably reproduced via the AiR sound source.

Only thing missing from the piano is Line-Out jack and digital display for navigation and other settings.

However the digital display alike feature can be achieved by the free Chordana Play app integration.

With duet and layering mode you can speed up your learning curve and explore new experiences with.

Lastly I can say that If you are serious toward piano playing and want uncompromising sound and feel Privia PX 770 might be one of the finest choice to proceed with.

82% positive feedback from more then 120 reviews over Amazon simply reflects the love the piano is getting from its user base.

    Hey Daniel. I was quite confused about the speaker’s system of px 770 does it also has a 2-way speaker system as px 870? And do I need to purchase a stand separately ?

      Daniel Cooper says:

      The stereo system of PX 770 is quite good and vibrant but it does not a 2-way speaker system but PX 870 does. And PX 770 comes with the stand you don’t need to purchase it separately. These type of models are known as console pianos. BTW you can find the difference between PX 870 and PX 770 here.

      Hi Michelle, I would not suggest that you do not try to open the piano on your own. Cause the keys are works on very sophisticated mechanism and a minor misplacement can even break the sensor.
      I suggest you either call Casio Customer Service (1-800-706-2534) or reach them via e-mail. You can find contact info here
      And If you want to do this on your own then this video might help you.

    What is the actual use of concert play feature. Do a newbie needs this to be implemented in their earlier stage of learning? And what other options are available in the same price of casio px 770?

      Daniel Cooper says:

      Hello Anthony, The concert play feature adds on the music of the orchestra system on the background while you play your keyboard, making a beautiful combination like you are playing (or performing) as a part of real life orchestra.
      Concert Play feature has nothing to do with learning stages.
      And, Its hard to suggest something at the same budget cause Casio PX 770 is a wonderful deal on its own. But some other options worth consideration are YDP 103 , PX 160 and Korg D1.

    Hi! I have a Casio Priva PX-3BK. I only use it to train piano in my room using a headphone and sometimes I plug in a speaker when I’m alone at home, besides that, I use as a midi controller with DAW and VSTs. I barely use other functions and sounds besides the Grand Piano.

    A friend of a friend knows that I have this piano and is offering his Yamaha P-45 in exchange.

    Do you think that can be a good deal, having in mind that I only want a Piano with the best grand piano sound and the sensation that I’m playing in a real acoustic piano with all the keys and weight? A good integration with DAWs and VSTs is important too.

      Hey Oto, Personally I have never used PX 3 so it’s quite hard for me to comment on the feel and sound. On the other hand P 45 is no doubt is one of the top notch piano with great Grand Piano sampled sound.
