Learning Piano with Digital Piano

When learning something, including a musical instrument, it is crucial to practice as much as possible. Knowing how to play and understanding how to it is different, and the discipline will bring good results when it comes to musical instruments. This is why choosing your instrument is essential in developing and learning progress. The choice of a musical instrument may vary based on what piques your interest, but regardless of choice, we will still need to practice it to play better.

Talking about musical instruments, we, as casual players or learners, are always concerned about making the first investment, especially when it comes to large instruments like the piano. The cost of an upright can be around $3000 to $6500 on average. High-end models can start from $10,000, which is far from affordable for many. This is why the digital piano is often preferred as an early investment and even a primary choice for financially unable players or if you don’t want to sacrifice the amount.

Professional musicians can choose their instrument with bigger freedom, but this is not the case for everyone. Can you learn piano without a piano? Yes, digital pianos are an excellent solution for everyone who wants to take a piano lesson but doesn’t have an acoustic instrument at home. A good digital piano will set you back from around $200, such as Rockjam 61, while most mid-range full-size will be about $500 and more, so it is much more possible to afford, even for parents who buy for their young children.

About Korg B2SP and Casio PX 770

The 61-keys models are ideal for young players or budget shoppers who don’t play complex pieces. Still, getting the full-size 88-keys digital piano is highly recommended if you will be playing on the acoustic instrument later. There are more than plenty of digital pianos to choose from based on the keys, budget, preferred brand, overall quality, and features. The more expensive will almost always offer more and provide a greater playing experience, whether from the sound or the keys action.

Some of the brands that you can trust for digital pianos are Casio and Korg. These companies are no strangers anymore to beginner and professional electric instruments. You can find an extensive collection from both companies to match your preference. Among their exciting variants, the Korg B2SP and Casio PX 770 are perfect choices for those who want an upright-styled digital piano. They are the solution for piano learners or enthusiasts without breaking the bank.

We have talked about the original variant of B2SP in our Korg B2 Vs Yamaha P125, and they are very much a version of each other. The B2SP is more expensive because this is a complete setup with the table and pedals, while B2 only gives you the piano unit; the sound technology and keys are the same. Is Kord B2SP a good digital piano? Yes, this is a very suitable option for anyone interested in having a full-size piano in the house but also prefers to display it.

It is very similar to the Casio PX 770 or the Privia 770. Digital pianos that come in a full setup like these two are often chosen by people who want to incorporate the instrument into the interior. Comparing Korg B2SP and Casio PX 770, the highlighted difference is their keys. This is because key action is crucial in mimicking the experience of an acoustic piano with its mechanical system. An ideal key action will help players develop the perfect playing technique when they play the real piano later.

Korg B2SP and Casio PX 770 Design

The difference between Kord B2SP and B2 is with this table inclusion, which also makes the package heavier. The pianos are the same, and you can find them in both black and white shades. The piano is quite eye-catching due to the large speaker grills that you can find at the top front of its surface. The piano itself is only 25 lbs. but the table setup adds another 23 lbs. into the shipping weight or probably more. The package also comes with three pedals attached to the table.

Similarly, the Casio PX 770 is also coming with three pedals attached to the table or stand. The cabinet is very similar, and they are made of standard wooden material that seems quite durable. The weight of PX 770 is 69 lbs. in total, but the piano itself is standard size. It is 54.7-inch wide, slightly wider than B2SP, and 11.7-inch deep. As for the shades, this model is available in black, white, and brown shades. Unlike the B2SP, the control panel of PX 770 is located on its left panel.

Korg B2SP and Casio PX 770 Speakers

Still, about the design, some people may wonder where the speakers of Korg B2SP and Casio PX 770 are located. This is one of their main differences because Korg put the speaker at the top firing upward, which means a cleaner sound for you and other people in the room. It is also louder than PX 770 with 2x 15 W speakers and Motional Feedback to improve sound quality. Casio uses speakers that fire from the bottom of your piano, and it is 2 x 8 W, good for small rooms but not more than that.

Korg B2SP and Casio PX 770 Keys Action

Moving to the most important part, let’s see what the Korg B2SP and Casio PX 770 can offer, starting from the keys. Korg uses NH technology for this piano and the B2 variant, which is very similar to Yamaha’s GHS but is slightly lighter. It is a good, standard action for this price point and is both weighted and touch-sensitive. The keys feel heavier on the low register and lighter as it goes to the higher register. You can adjust the sensitivity among three presets; light, normal, and heavy.

The surfaces of the keys are glossy for the white keys and matte for the black keys. PX 770, on the other hand, simulates the Ivory and Ebony feel of an acoustic piano for a better playing experience. What’s more attractive is that Korg uses their Tri-sensor Scaled Hammer Action for this piano weighted with actual hammers instead of strings. This technology is trying to recreate the movement and experience of acoustic pianos; lower register keys are heavier and gradually become lighter as they rise to the higher register.

It is also touch-sensitive, and each key has a triple sensor to detect touches of the keys and allow players to play the keys repetitively at higher speeds. It changes in volume based on the playing intensity, and similar to B2SP, we can adjust the sensitivity in three different levels or turn it off to have fixed sensitivity.

Korg B2SP and Casio PX 770 Sound Quality

Next is for the sound quality of Korg B2SP and Casio PX 770. The B2SP uses PCM sampling technology which is a multisampling system. With each note we play, the piano key will simultaneously trigger up to 3 samples. It includes sympathetic and damper resonance to mimic the acoustic piano and improve the experience. As for the sound collection, this piano comes with five grand pianos, three electric pianos, pipe, electric organ, harpsichord, and orchestral strings.

On the other hand, Casio uses their proprietary AiR Sound Source with increased memory and provides room for better samples and more accurate sound. The sound samples seem to be improved compared to their predecessor, probably by re-recording the instrument. It has 19 sounds, including five grand pianos, four electric pianos, four organs, two strings, vibraphone, harpsichord, and bass. Both Korg B2SP and Casio PX 770 also have a reverb effect with 120 and 128-note polyphony, respectively.

Korg B2SP and Casio PX 770 Features

Lastly, for the additional features, both Korg B2SP and Casio PX 770 also come with some. But, surprisingly, Korg misses some of the most popular and valuable modes in this piano, such as Layer and Split, which are available on the Casio. It only has Duo mode, a four-hand mode, so two people can play with the same keys. Layer and Split modes enrich your play since we can combine two sounds with these methods.

Korg B2SP Vs Casio PX 770

Both Korg B2SP and Casio PX 770 are good furniture-styled pianos made to help you practice, play, and improve the room. They are not identical; Casio PX 770 is a more expensive choice and comes with better keys. The key action on this model is among a few of the best in the price range and considered a premium touch that feels very similar to the acoustic instrument. It also has more playing modes to enrich your experience.
