Korg B1SP Review 

 October 25, 2020

By  Zen Chung

The Dance Music mode and the classroom mode are two other characteristics that are special to this system (and that we really liked). Casio did a really nice job of creating this keyboard even for a beginner fully playable.

Altogether, this piano is a learning tool and an entertainment hub all in one. We recommend this to any budding musician looking for a fun piano buddy they can create good music with on the go.

For some time now, the Korg B1 digital piano has been around. It’s one of the market’s most common entry point. I will highlight every element of this tool in this Korg B1 analysis. You will have all the data you need to reach your own inference about whether the Korg B1 is correct for you by the end of this evaluation.


The Look

The Korg B1 has been intended as a digital mobile piano. With a contemporary accent, it sounds easy. What distinguishes the Korg B1 is its bent edges. This provides it a smooth and cozy atmosphere where you are invited to perform music.

Modern design of the Korg B1

The lengthy broad speaker grill on the korg B1 is another thing you might immediately notice. It requires the surface area to a big extent. Personally, I’m not a large speaker grill supporter, but I can live with it if it helps to enhance sound performance.

Music Rest

The rest of the music with Korg B1 is quite distinctive. From other producers, I have not seen anything like this. The music rest has straight lines and mildly sharper angles unlike the instrument itself. It’s not very broad but it’s certainly high enough to help any score book or sheet music printed.

The Unique Music Rest on the Korg B1

The placeholder at the crossroads is what is rather distinctive about the music resting on the Korg B1. I discover Korg’s really reflective touch.


The Korg B1 control panel is very simple and clean. It is made up of 1 button size and 4 buttons. Here I enjoy the simplicity. You have 1 piano sound key in addition to the energy button, 1 button for other sounds and 1 last key to switch on metronome. Like any other digital pianos on the market, a mixture of buttons and keys on the Korg B1 is required for many advanced functions.


There are 88 keys to the Korg B1. All of them are plastic. The black ones are matte and the white keys are shiny. It feels like the Yamaha P45. The keyboard feels nice and well-constructed. There was no irregular spacing between the keys I noticed.

Size & Weight

The Korg B1 is tiny in size and lighter in weight as a portable digital piano. The Korg B1 is mildly closer than its business rivals thanks to the speaker grill. It’s like the Yamaha P45 and Casio PX 160 about the same weight. The weight of the Korg B1 is around 12 kg (26 lbs). Without music rest, it has the dimensions of 131(W) x 33(D) x 12(H) cm (52” x 13” x 5”)


You’ll discover on the Korg B1 what they call the Natural Weighted Action keyboard. There are true hammers behind the strings to simulate an acoustic piano’s main intervention. The keys are graded and weighted. Each important weighs differently. Like an acoustic piano, it moves from stronger on the left hand to weaker on the correct hand. The buttons are also sensitive to touch. You can change the sensitivity amount to your preferences.

Overall, I discover that Korg’s Natural Weighted Action is very comparable to Yamaha’s GHS on the P45. Korg B1 is mildly lacking in dynamic compared to the Casio PX-160. The keys on the Casio PX-160 has also Ivory/Ebony key tops. This contributes considerably to the absorption of grip and moisture during lengthy meetings. It’s sad that this is not what the Korg B1 has.


The PCM Stereo Sampling is the sound engine on the Korg B1. It was taking samples from an acoustic piano session. Synthetic string and damper resonance are also available. This contributes a lot more information and enhances the sound. The Korg B1 sounds about the same quality as the Yamaha P45 in my view. And with a little bit more wealth, I discover the Casio PX-160 sounds a little easier.

The Korg B1 has two speakers of 9 watts. They use a unique technology called Motion Feedback behind the speaker grill to regulate speaker motion. This gives the Korg B1 a much better sound performance. The speakers as a whole and not very loud. But filling a tiny to medium sized space is sufficient.


What the Korg B1 really lacks is its characteristics. It has no capacity for inner recording. There’s no dual or split mode available. The sound choices are quite restricted. And you can’t listen to and exercise with any inner music. The sound choices are quite restricted. And you can’t listen to and exercise with any inner music. Another major drawback is that the Korg B1 has no USB or MIDI connections. The Korg B1 is really bare-bone, a wise feature.

A list of the most significant characteristics of Korg B1 can be found here:

Sound (15 total):

  • Piano × 3
  • E.Piano × 2
  • Organ × 2
  • Harpsichord

Polyphony: 120


  • Duet Mode: split the keyboard to identical halves

Connectivity: Headphone jack


The Korg B1 comes with a knob and a music rest. The Korg B1 provides you a suitable piano pedal, unlike many of its rivals. This pedal looks genuine and performs quite well. It also supports half pedaling in this price range that you couldn’t discover on other designs.

You may need to buy a different stand and seat depending on the package you get. Like any other digital mobile pianos, you can choose between stand and table or mobile style furniture style computers.

For any digital pianos, a nice couple of headphones is always suggested.

Even though the Korg B1 speakers are somewhat superior to their rivals. For any severe results, it is still not very great enough. You still need an internal speaker / monitor for that.


The Korg B1 is an entrance-level digital piano on a narrow budget exclusively for beginners. It’s a very bare-bone, low-priced instrument.

Also suitable for any gigging artists who have just began their profession is this piano. It’s easy to carry around and an investment isn’t too large.

If you have more expertise or a bigger budget, however, there are many other much better options on the market for you.


The Korg B1 operates as a digital piano in general. But it’s all about it. You’re not expecting much more from that.


Korg B1 vs. Yamaha P45

Korg B1 has about the same performance main activities compared to the Yamaha P45. The knowledge of working on these two instruments is more or less the same. No inner recording capacity is available for either Korg B1 or Yamaha P45.

Compared to the Yamaha P45, the Korg B1 has better amplifiers. Through speakers it certainly sounds better. In contrast to the foot-switch that goes with the Yamaha P45, it also comes with a correct piano pedal. Another benefit of the Korg B1 is that it has nearly twice as many polyphony points as possible.

The Yamaha P45 also has many benefits at the same moment. It’s got a lot more sounds to choose from. There are quite a lot internal songs that you can listen to and practice with. The P45 also has a USB jack that you can connect the instrument to a computer.

Korg B1 vs. Casio PX-160

Another Korg B1 rival is Casio PX-160. They’re about the same variety of prices.

In my view, the PX-160 has a far stronger main intervention. When I perform on the Casio PX-160, thanks to the better keyboard dynamics, I feel more comfortable and more creative. The PX-160 keys have Ivory / Ebony trim as well. This really enables with lengthy sessions of playing. I also find the Korg B1 mildly stronger for the sound motor on the Casio PX-160.

Both of these instruments have comparable displays. The base output of the Korg B1 is mildly superior. I find the base a bit hazy on the PX-160.

Just like the Yamaha P45, a horrible foot-switch arrives with the Casio PX-160. The Korg B1’s adequate piano pedal is a major benefit.

Unfortunately, on many other dimensions, the Casio PX-160 victories. It’s got a lot more sounds to choose from, lots of inner songs, 2 additional styles and a USB jack. The PX-160 can also record your performance internally. This is a function that neither the Korg B1 nor the Yamaha P45 has.
