Buying a Digital Piano

Digital pianos are ideal for almost everyone who wants to take piano lessons or have the instrument to play at home. They are typically cheaper, and you can even find options below $200 for a full-set of 61-keys digital pianos. Parents with children taking the lesson can spend the amount on promoting the practice at home. Even professionals play digital pianos because they are easier to carry or store in a limited space while also versatile to work with their computers.

However, due to the extensive number of options, selecting one can be confusing. What is important in a digital piano? You may have to consider several points before making the decision. First is the convenience and portability of whether the instrument will be transported often or if you have limited space to put them. The second is the cost because not everyone can spend the same amount. You can match the budget to what the digital piano must offer.

Third is their key action because acoustic piano keys don’t feel the same. It is great to have a digital piano that can mimic the weight or sensitivity of the actual instrument keys; usually, this feature is available on mid-range options. Fourth is the sound quality and collection because digital pianos produce sound based on the acoustic piano recording. Besides piano sound, you can find other instrument sounds, such as bass or strings, to enrich the playing experience.

About Korg B2 and Yamaha P45

There are a decent amount of options from well-known companies and manufacturers. Some people may prefer a particular name or maker, and almost all famous manufacturers such as Korg and Yamaha carry entry-level digital pianos in their collections. We also tend to shop from well-known names because they are easy to find and have a credible reputation to trust their products. If you are shopping on a budget, the Korg B2 and Yamaha P45 are two interesting options to consider.

If you have been scrolling the beginner digital piano list, chances are you have met these models before. The two are among the most popular entry-level pianos from both companies, and they offer similar qualities. We can’t say they are groundbreaking or the best piano you will ever have, but they are certainly impressive for the price point. Suppose you want a more serious alternative with a higher price point. In that case, we recommend checking the Korg B2 Vs Casio PX 770 because the Casio model is a better choice among these alternatives.

The Korg B2 is affordable for learners and casual players with good sound sampling and key action. It comes in three variants; this original model, B2N, and B2SP. The B2 and B2SP have similar technologies, but the latter comes with a piano stand and pedals. The B2N is a lightweight model, and it is about the instrument weight and key action because it is lighter than the other two.

The P45 is a similarly promising option, and we think it is almost identical to the B2 both on the playing experience and price point. Is Yamaha P45 good for beginners? Absolutely, this entry-level piano is a high-quality product and versatile for players on various experience levels. Many may recognize the P45 as P71 because they are identical pianos. Most sellers sell P45, and P71 is exclusive to Amazon customers. In comparison between Korg B2 and Yamaha P45, we recommend B2 for the sound quality.

Korg B2 and Yamaha P45 Design

Before checking what the Korg B2 and Yamaha P45 can offer, let’s take a look at the pianos first. The two are almost identical in form factor and weight as they are about 25 lbs. as the instrument only. The width of P45 is 52-inch, slightly wider than B2 and its depth is 11.6-inch which is more compact than B2. However, the height or thickness is taller on the P45. The sample is black, but you can find B2 in white fashion, too, while for P45, it seems they are only available in black finish.

Both pianos put their control panel on the top half of the surface, and here you can see Korg has a volume knob while Yamaha has a volume slider. The control panel is straightforward on these pianos, and there are no dedicated buttons for each function or sound. For example, to dial a specific sound in P45, we must press the Function button with the particular piano key. The lack of display also makes it less convenient to see what mode the piano is on.

Korg B2 and Yamaha P45 Keys Action

Now for the most important part, let’s look at the keys. Many wonder whether the Korg B2 and Yamaha P45 are fully-weighted digital pianos, and the answer is yes, they are graded to have different weights on the lower and higher register. Each company, including these two, have their proprietary technology. Korg with their NH and Yamaha with their famous GHS. In practice? These technologies are very well mimicking the feel of acoustic piano keys but don’t feel the same.

They are probably more on the light side as there is no real hammer inside, but side by side, the keypress of Korg B2 is slightly lighter than P45. Besides being graded, the keyboards are also touch-sensitive, which means they can dial volume based on the intensity of the play; the harder you hit the key, the louder the sound. In addition, this sensitivity can be dialed to match your preference between three different levels. The keys are plastic, and sometimes they are slippery too when your palm is wet.

Korg B2 and Yamaha P45 Sound Quality

Next for the sound sampling technology, the Korg B2 and Yamaha P45 are using their style too. Korg with its PCM sampling and Yamaha with its AWM dynamic sampling technology. AWM can sound better on the higher piano collection, but the one they use for P45 is pretty basic stereo sound from their full concert grand piano. It sounds beautiful, but we are disappointed with its lack of sound built-in the instrument since many similar alternatives can offer many more.

Yamaha P45 only has ten built-in sounds, including two grand pianos, two electric pianos, two pipe organs, two harpsichords, vibraphone, and strings. Korg B2 uses multisampling technology that triggers up to 3 samples simultaneously. B2 suffers from the same issue as Yamaha with its built-in sound. It is slightly more than 12 in total, including five grand pianos, three electric pianos, pipe, electric organ, harpsichord, and strings. As for the polyphony, the count is 120 and 64-notes, respectively.

Korg B2 and Yamaha P45 Speakers

Unlike stage piano, where you need to connect them into a separate sound system, the Korg B2 and Yamaha P45 come with dedicated speakers. They are located at the top of the unit, making sure the sound is clean and louder. We think they are loud enough for a small room but nothing more. The P45 has 2 x 6W speakers, while B2 features 2 x 15W speakers. We can also plug headphones into the jack when playing night or in silence.

Korg B2 and Yamaha P45 Features

Lastly, there are several useful functions for the features in both Korg B2 and Yamaha P45. One of them is metronome to help play with tempo. You will find typical features such as Duo mode, which is very useful if you have more than one person playing the instrument, such as with the teacher. This mode will split the piano keyboard into two identical parts with the same notes. Yamaha P45 also has layer mode, which is unavailable on the B2.

Layer or Dual mode is a function where the piano will put two different sounds and let you play them simultaneously. The Split mode that separates the keys into two parts for different instruments is sadly unavailable on both pianos.

Korg B2 Vs Yamaha P45

There are so many good digital pianos, and these two are some of the most attractive entry-level to buy. The main differences are key action, sound collection, speaker, and features. The Yamaha P45 is slightly heavier to press, but the two are still light. The sound collection lacks bass, but Korg B2 has more built-in sounds. The speaker of B2 is also louder, but this piano doesn’t have the layer mode for a richer playing experience.

-The B2 provides a total of 12 sounds that cover a diverse range of genres.
- This instrument uses a Natural Weighted Hammer Action (NH) keyboard that reproduces the same feel that results from the hammers on a real acoustic piano.
- The B2 provides connectors that allow using the instrument in conjunction with a variety of software and music hardware.
- By connecting your smartphone's headphone jack or your music player, you can output your favorite music through the speakers of the B2 and enjoy playing along.

- GHS weighted action is heavier in the low end and lighter in the high end, just like an acoustic piano
- Contains 10 different voices, including digitally sampled tones from real Yamaha acoustic grand pianos
- Dual mode lets you combine 2 voices together, like piano and strings, for an inspiring new playing experience.


You can go fantastic with any of these pianos. They are currently priced at the same level, but we will recommend Korg B2 for its more sound collection and speaker. This piano sound is enjoyable and natural, with a simple control panel to navigate the functions.
