Casio PX-770 Review



Today we’ll be reviewing the Casio PX-770, or we might call it the little brother of the Casio PX-870. But also known for being the successful sequel to its predecessor Casio PX-760.


The PX-770 did replace the px-760 with some significant improvements. But it is also quite similar to the PX-870.


However, this digital piano with a furniture cabinet is also one of the cheapest digital piano in the privia-series, which makes it even more interesting for us.


Further down in this Casio PX-770 review we’ll go through the most important facts you need to know about before buying this piano.


So let’s dive into Casio PX-770 review.


Design


The PX-770 has a sleek design, a bit redesign than the predecessor, which now looks very promising. It’s made very compact so it can fit all necessary spaces but also has a wooden texture on the cabinet to make it fit like a decor.


Provides a sliding cover to keep dust and dirt away from the keys so you don’t need to clean the keys as often as many other pianos do. But also gives it a better look, if you’re tired of constantly seeing the keys, then just pull over the cover and enjoy the PX-770 as a beautiful piece of furniture in your house.


When the PX-770 is fully assembled, it reaches approx 70 pounds. Which can be considered pretty much and might require 2 people to move it, if that’s necessary.


The dimensions are 54.7 width, 11.7 depth and 31.4 height.


But also keep in mind that this digital piano is not made as a portable piano. Don’t buy this piano with the belief that you’re taking it with you on vacation, though it’s not impossible but it aint particularly smooth.


This piano is made to be placed in peoples houses, not being on the run all the time, consider something else if a portable piano is a must for you.


Assembling the PX-770 won’t be especially hard. It’ll take approx 30-45 minutes with a screwdriver. As long as you follow the guidelines in the manual, you’ll not encounter any problems. But if you’re ignoring the manual, it might take a bit longer and you’ll probably do something wrong.


Anyways, the PX-770 will feature three pedals. Sostenuto, soft and sustain pedal. The sustain pedal is the most common pedal and the other two won't be used especially much. These are also the three pedals we found on an acoustic piano.


The PX-770 can be bought in three colors, black, brown and white. Where the black is the most popular option.


Regarding the buttons, they have located the control buttons on the left side on the piano which makes it a structured piano easy to navigate around.


You’ll find an on & off button at the top, just beneath that you can control the sound.


Then you’ll have the function button which will be used to access most of the function and settings on the piano. For instance, press down the function button and the sound you want to play, then you will hear a beep which says if the selected button was pressed properly.


Fast navigation to grand piano sound and electric piano can also be found on the left control button location.


The other sounds can be found under certain keys with a little texture above which tells you what sound it is.


Recording, pause and play buttons are also provided. But we’ll go through that further down.


Key action


The keys are 88 fully weighted with simulated ivory & Ebony at the key tops. Tri-Sensor Scaled Hammer Action II is the key action casio uses in most of their digital pianos, so on in the PX-770.


Wouldn't call this key action new, but still provides a very good authentic piano touch thanks to the actual hammers replicating the acoustic piano as similar as possible. Which allows the player a real feeling on an acoustic piano.


That’s something all digital piano players are happy to take part in.


Also provides scaled hammers, meaning that in the left low end, the keys will feel slightly heavier than in the right high end where they will feel lighter. Which also means that the keys are weighted individually, similar to an acoustic piano.


The PX-770 does have touch sensitive keys. You can choose between three levels where the third provides the widest dynamic range, which is the opposite to the first one. You can also shut off the touch sensitivity completely and play at the same intensity all over.


The meaning of touch sensitive keys is that the harder you press a key, a louder sound the piano will provide. And the lighter you touch the keys, a lower sound will be heard.



Sound


The PX-770’s sound engine has a fenomenal superior capacity with Casio’s well known multidimensional AiR sound source system, which is not only used on the Px-770 but also on pretty much every digital piano made by casio in the same price range. For instance, the PX-870 does also have Casio’s Air sound source. And the sound quality on the PX-870 will never be doubted.


However, the technology in the AiR sound source is so good that the sound gets even better than it was before the AiR sound source.


The sound source has a very good memory allowing technology to compress data and prevent lossless data. Which also makes the high quality sound.


Comparing once again to its predecessor, the PX-760, we can see a significant improvement regarding the grand piano sound. The Px-770 grand piano sound is actually sampled from a real grand piano, at different dynamic levels.


Thanks to different samples variations concerning the grand piano sound, we then can enjoy a powerful pianissimo to the fortissimo.


The sounds overall are very good at the PX-770. They are significantly more natural than their predecessors.


Comes in four different levels of reverb, Room, Small Hall, Large Hall & Stadium. Same with the chorus, also 4 different types to play in. Tho, there isn’t any hall simulator as the PX-870 does. It is still not the most significant feature, but could be fun to have.


The sounds are 5 grand pianos, 4 electric pianos, 4 organs, 2 strings, vibraphone, harpsichord and bass.


Speakers


As mentioned earlier, the sound quality on the PX-770 is good. But the speaker system is less impressive.


A total of 16 watt divided on 2x8 watt speakers, which won't be that powerful as a real piano.


It’ll be enough to perform at home, but that’s just it. Performing in larger spaces, you’ll probably need an external speaker to fill up the room.


But still the quality is good, even better is that there won't be any distortion at any volume range.


Polyphony


Providing us with 128-note polyphony, which is a bit less than the big brother, but totally enough for any musician.


That is also the normal amount in this price range, actually everything between 128-192 is normal for this price.


However, the Polyphony is the maximum amount of notes that a keyboard or sound module can produce at one time.


Recording


The PX-870 offers two ways of recording. Either midi rec or audio rec. Unfortunately, the PX-770 only has one way of recording which is with Midi. It’s called the little brother for a reason.


However, you can record your performance with a 2 track midi recorder, meaning that two different tracks can be recorded separately.


With this feature you can record a left hand part separately and a right hand part separately and then mix them up to a song.


But yea, the recording options may lack a bit, but it should be enough.


Modes


The layer mode is the most basic one, kinda every digital piano nowadays has this mode function. What it does is that you can layer 2 sounds together and play them at the same time. Funny and easy as that.

The other one is duo mode, with this mode you can split the piano into two equal halves, one left and one right half. With this function you can play with your piano teacher or with a friend. It's also called lesson mode on many other digital pianos and could really help your piano exercise.

The third one is called the split mode, my favourite actually. Anyway, this one allows you to, for example, play the piano sound on the left part of the piano and the harpsi on the upper right.


Other features

The PX-770 does have a metronome built in. That’s a great tool you can use while learning how to play piano. It sharpens your rhythm sense and allows you to develop as a pianist.


You can play between 20-255 bpm by using the metronome.


Another useful function is the tuning function, which allows you to adjust the pitch on the keyboard from the A440 tuning.


We also have the octave shift, what it does is that you can use it to change the pitch on your piano throughout two octaves.


Lastly, we have the transpose function, which makes it possible to hear a song in a different key by shifting semitones up and down.


Connections


The PX-770 features all the necessary connections you’ll need.


If you want to play quietly with headphones, or connect an external device, then you’ll use the quarter inch stereo jack placed on the front side of the PX-770. Many times there is a line out jack to connect external devices, but in the PX-770 you'll just use the stereo jack.


Then the PX-770 also has a USB to host type B, which makes it possible to connect your computer to the digital piano and easily exchange midi data. Very useful feature if you make music with a DAW (digital audio workstation) and thereafter you can use your digital piano with your DAW. FL studio for instance.


Accessories


One of the big advantages considering the PX-770 is that you don't need to buy a piano stand and pedals separately. That will be included in the box when purchasing the piano, you can easily save some money and time by choosing a piano that already has these accessories included. Otherwise it’ll cost you about 200-300 dollars to buy separately.


You will also get an owner manual so you can navigate around the piano, but also a music rest where you can keep your sheet music.


The music rest is very easy to assemble, it has two plugs underneath which you plug into the piano very easily. But also very easy to remove.


Unfortunately, you will not get any headphones included, but that can of course easily be bought seperately. Then you also have the option to choose which one suits you the best.



Pros & Cons


Pros

  • Comes with a great polyphony rate, 128 which should be enough.

  • Featuring Casio's famous Tri-Sensor Scaled Hammer Action Il.

  • A reasonable price for 19 high quality sounds.

  • Compact and sleek design with a sliding lid to prevent dust from the keys.

  • Includes a stand and music rest, no need to spend money on that separately.

Cons

  • No audio recorder option.

  • No option to connect USB flash drive.


Little brother vs big brother (PX-770 vs 870)


Comparing these two against each other, we’ll notice significant differences but also similarities.


The PX-870 does have a higher polyohny rate, 256 which is considered very high and also very good.


But the PX-770 has a 128-polyphony rate which is considered more ‘’normal’’ and is totally enough. But the more the better.


Both provide the same amount of sounds, 19 sounds on each of them.


There are many more things you might wanna know about regarding these two pianos. I recommend you reading our PX-870 review to get a better understanding between these pianos.


Conclusion


Buying this piano will probably not make you disappointed. We can say that you clearly get what you’re paying for.


If you don’t wanna go broke, but still want a cabinet digital piano. Then the PX-770 can be a good option for you.


It provides all the necessary features, so either as a beginner or intermediate you should be comfortable with this piano.


You’ll have access to 19 high quality sounds throughout the AiR sound source, but more important the 128 note polyphony which should not disappoint you.


As mentioned before, this piano comes at a fair price, which makes it attractive for beginners and intermediate players. So if you’re looking for a new piano, then I will strongly recommend the Casio PX-770.
