Buying a Digital Piano

Digital pianos have been an excellent solution for almost every enthusiast to start their journey in modern days. Not everyone has the actual piano in their home, and digital pianos are much more affordable to invest in. The electric instrument is also versatile and trusted by professionals because it can mimic a real piano very closely to have a similar playing experience. While sound-wise, they are not natural; it should be enough to help people know more about the instrument and how to play them.

Are digital pianos as good as the acoustic? Depending on what this question is applied on, sound-wise, they are not as natural and as good because the sound of digital piano comes from recording with some technologies to make it as rich as possible. Digital piano’s primary goal is to mimic the sound of an acoustic piano. Do they sound bad? No, depending on the model and technology, many high-end, expensive digital pianos are better than the acoustic piano sold around the same price point.

Is it worth buying a digital piano? Yes, a digital piano is like the acoustic instrument and if you will be playing or learning on it. However, we recommend buying the option that meets your goal or preference. Chances are, the more we pay, the more we get from the instrument, such as better keys action and better sound quality. Especially for the keys, it is essential to choose a solid option that comes with fully-weighted and touch-sensitive to mimic the feel of keys on the acoustic pianos.

Korg B2 and Yamaha P125 Design

It seems that there are few models to the Korg B2, namely B2SP and B2N. What is the difference between Korg B2 and B2SP? The B2SP is a piano set up with the table and pedal, so it is more expensive, while the B2N is a “lightweight” variant; the piano is lighter, and the keys action is lighter than the other two. As for dimensions, the Korg B2 is 51.6-inch wide, 13.2-inch deep, and 4.6-inch tall. The instrument is 25 lbs. in weight and comes in black and white shades.

The Yamaha P125 is also a pretty-looking piano, but this model is a bit chunkier than B2. The piano is still made of plastic and weighing at 26 lbs. It is available in black and white without a table or pedal inclusion. The P125 dimensions are 52-inch wide, 11.6-inch deep, and 6.5-inch tall. Yamaha has a dedicated button for each sound, so dialing them is more convenient, but it has a volume slider instead of a knob.

Korg B2 and Yamaha P125 Keys

As mentioned above, one of the most crucial parts of a digital piano is the keys. Starting with Korg B2, this piano is suitable for beginners, and the keys are featured with NH or Natural Weighted Hammer Action. The keypress on this piano is a bit on the light side compared to GHS action, which P125 uses, but the difference is very small. The keys are good to let beginners and students understand what a real key on piano feels like; it is sensitive.

It means the harder they press, the louder the sound will come out. There are three preset levels to adjust this sensitivity from light, normal, and heavy so you can change how the key feels. The white keys are glossy, and the black keys are matte, which may cause some slipperiness if your hand often sweat while playing. One issue we want to mention about B2 is that if you play multiple keys at once and fast, they don’t register well.

Moving on to Yamaha P125, this piano comes with GHS or Graded Hammer Standard, similar to most, if not all, affordable pianos from Yamaha. This is a fully weighted system to mimic the experience of acoustic keys. It feels heavier on the lower register and gradually lighter to the higher notes. The keys are touch-sensitive, too, so we can learn the dynamic of playing the piano. It also has several levels, from soft, medium, and hard. You can deactivate the function by choosing the fix option.

The key’s surface is similar to Korg B2 or shiny on the white keys and matte for the black keys. We have no issue with slipperiness or discomfort, but some may find the glossy keys lacking grips when playing extensively or in a humid room.

Korg B2 and Yamaha P125 Sound Quality

Next is for the sound quality of Korg B2 and Yamaha P125. Like most digital pianos, the sound on these pianos is sampled from a real instrument. Yamaha, for example, is using the Pure CF Sound engine based on CFIIIS 9 Concert Grand piano. Each of these notes is recorded multiple times, and Yamaha uses 4-layer sampling instead of 3-layers like in the older piano. This additional layer is meant to improve the dynamic and transition between samples.

Extensive features like damper resonance, string resonance, and key-off simulation are also included. As for the sound collection, the P125 has four piano sounds, four electric piano sounds, four organ sounds, four sounds for clavichord and vibraphone, four sounds for strings, and four bass sounds. As for the Korg B2, this piano has five grand piano sounds, three electric pianos, harpsichord, electric organ, pipe organ, and orchestral strings; it doesn’t have bass sounds which is quite unfortunate.

The sound technology in Korg B2 is called PCM sampling technology which is also multisampling but only up to 3 samples. This technology means that each note pressed the trigger will affect three samples for a rich and more natural sound. This piano includes sympathetic and damper resonance too. Both Korg B2 and Yamaha P125 have reverb effect, and for polyphony, Yamaha is richer up to 192-note while B2 is 120-note similar to many affordable digital pianos.

Korg B2 and Yamaha P125 Features

Lastly, we want to look at the additional features on Korg B2 and Yamaha P125. Usually, digital pianos have split and layer modes found on the P125. The B2 only has the duo mode, which is also available on the Yamaha piano. You get a 3-month free plan to Skove, and this is an excellent solution for a beginner learning the instrument. In Yamaha, you can use this piano with their Smart Pianist app.

The P125 also comes with split and layer mode and bass sound to expand your experience.
