Specifications and Features

The Casio PX-780 is a true evolution within the world of the Privia digital pianos. What sets it apart is its new keyboard action and also the new sound engine that is included, which is nothing short of powerful. Put together, it gives a level of expression, nuance, and detail that makes it feel like you are playing a grand piano. It achieves all of this while looking stylish and being lightweight.

The piano sound in Privia was already award-winning but it has been further improved in this model. The PX-780’s memory capacity is three times bigger than past generations, and this gives it a truly natural piano tone. Furthermore, the Acoustic and intelligent Resonator (AiR), a Casio proprietary sound source, is incredibly detailed and realistic.

Put together, you will be able to perform powerfully and expressively. Plus, the Damper Resonance simulator makes the whole thing sound even more real, with rich string sounds particularly when you use the pedals.

The key action has also been redesigned, including the 88 note scaled hammer Tri-sensor action. The textured keys feel real, and it comes with three sensors to really capture the dynamics you would expect from a grand piano. The sensors record how fast you play, how hard you press the keys, and your timing.

You also get 250 built -in instrument tones. These include bass, drums, brass, electric pianos, organs, and strings. Plus, you can use the piano for live performances by keeping your favorite layers and splits at the ready. The 180 drum patterns that are included with their auto accompaniment and the ability to compose your own songs with the 17 track recorder provide the finishing touch. Plus, thanks to the audio outputs, you can connect your Casio digital piano to any other sound reinforcement and recording equipment.

Casio has always been committed to giving users “class compliant” USB connectivity and this is also included on the PX-780. This means that you can use your piano with a Windows or Mac computer, from where you can also download further drivers. Thanks to the USB MIDI, you can use Apple’s Camera Connection Kit and controlling your iPad.

In order to make sure the PX-780 sounds like a real acoustic grand piano, Casio have added the AiR processor to the Privia devices. This means that grand piano samples have been recorded in four different dynamics to make sure that the sounds you hear are just like those of a true grand piano. These include remarkable expression and long natural decays. Furthermore, the sound of open strings is perfectly simulated when you use the pedals to raise the dampers.

The Good

  • Value - The value for money truly is amazing. This is an affordable model that gives you the quality that even the world’s more expensive brands will struggle to achieve.
  • Features - It comes with fantastic helpful features, key action, and sound quality. This means that you can create a realistic experience. You will be able to find different brands that may be better than the Casio on at least one of these three things, but you will not find one that is in the price class of the PX-780.
  • Quality - It comes with some excellent details, like the simulated ebony and ivory keys, 128 polyphony notes, and 250 instrument tones built-in. No other manufacturer is able to offer all of this for this price.

The Bad

  • Congruency - Some people find that it sounds so much like a real grand piano that they struggle to put the sound and the image together. This is enhanced by the fact that it is not overly portable.
  • Malfunctions - There have also been a few reports of the headphone jack malfunctioning.

Is The Casio PX-780 Right For Me?

Best Suited for…

Stage recorders, studio recorders, and advanced players

Not So Great for…

Beginners or inexperienced players

The Final Verdict

If you want to have a high quality, realistic model, but you are on a budget, then the PX-780 is the answer for you. It has excellent key action and sound quality, and some fantastic features and instrument sounds, which is more, in fact, than any other keyboard in the same price class.

It is not the most attractive model but if you want to have a beautiful looking piano, you may want to consider getting a real grand piano. While this model is not suitable for beginners who have never played before, this is only because the many features it comes with will go to waste. But for the performing or recording musician, or budding musician, this is the ideal device.
