Each model reflects the heritage and priorities of its brand, and this section delves into their differences in design philosophy and overall construction.
Yamaha YDP-145
The Yamaha YDP-145 inherits the classic, understated style Yamaha is known for. Its design is reminiscent of an acoustic upright piano, with a traditional-looking cabinet and clean lines that make it easy to integrate into various home environments. Its compact size is one of its standout features, appealing to users who need a piano that doesn’t dominate their living space. This makes it ideal for apartments, smaller homes, or rooms with limited space.
The materials used in the YDP-145’s construction are a combination of MDF (medium-density fiberboard) and high-quality plastics. While these materials are standard in this price range, Yamaha has ensured a sturdy, well-assembled product. The surface finish is smooth and resists fingerprints and dust, making it low-maintenance and easy to clean. The matte texture of the black finish, in particular, adds a premium feel, while the rosewood and white finishes offer options to suit different aesthetic preferences.
The three integrated pedals (soft, sostenuto, and damper) are well-crafted, and their metallic finish gives them a sturdy feel underfoot. The sliding key cover is another practical inclusion, providing protection from dust when the piano is not in use. However, some users may find the thickness of the key cover slightly flimsy compared to higher-end models.
One aspect where the YDP-145 falls short is its music rest. While functional, the rest is relatively small and may struggle to hold thicker music books or larger scores securely. This might not be a dealbreaker for casual players, but those who frequently use sheet music might find it less accommodating.
A noteworthy strength of the YDP-145 is its weight. At approximately 38 kg (83.8 lbs), it is lighter than many of its competitors, including the Kawai KDP-120. This makes it easier to move if needed—a practical advantage for those who frequently rearrange their space or anticipate relocating the instrument.
Overall, the Yamaha YDP-145 strikes a balance between practicality and style. Its design is appealing to those who prefer a classic aesthetic with a focus on compactness and ease of use.

The Kawai KDP-120, on the other hand, takes a slightly different approach to design. It maintains a traditional aesthetic but introduces a more modern flair through subtle details and proportions. Its cabinet design is larger and taller than the Yamaha YDP-145, giving it a commanding presence that more closely resembles an acoustic upright piano. For users who value the visual impact of their piano, this added size can lend an air of sophistication to the space.
Kawai uses high-quality MDF for the KDP-120’s construction, ensuring a durable and sturdy frame. The finish options—premium rosewood, satin black, and white—are rich and well-executed, providing versatility for different interior styles. The satin black finish, in particular, has a sleek and elegant appearance, while the premium rosewood finish introduces warmth that suits more traditional spaces. These finishes resist scratches and smudges, maintaining their aesthetic appeal over time.
A key strength of the KDP-120’s design is its music rest. Larger and more robust than the Yamaha’s, it provides ample support for sheet music, books, or even tablets. The addition of subtle grooves at the base of the rest helps prevent pages from slipping, a small but thoughtful touch that reflects Kawai’s attention to detail.
The integrated pedal unit is another highlight. Like the Yamaha, the Kawai KDP-120 features three pedals that replicate the functionality of an acoustic piano. The metallic finish of the pedals feels premium, and the pedal frame is sturdy, providing a reliable experience for advanced techniques such as half-pedaling. Additionally, the slightly elevated design of the pedal board ensures a comfortable playing posture, especially for younger players or those who spend extended periods practicing.
At approximately 40 kg (88 lbs), the KDP-120 is slightly heavier than the YDP-145. While this added weight contributes to its sturdier feel, it can make the piano more challenging to move.

Keyboard and Playing Experience
When it comes to digital pianos, the keyboard and playing experience are arguably the most critical aspects. After all, the primary goal of a digital piano is to replicate the feel and responsiveness of an acoustic piano. Both the Yamaha YDP-145 and Kawai KDP-120 feature weighted keys and graded hammer action to simulate the mechanics of a real piano, but they differ in their execution. This section provides an in-depth comparison of the key material, texture, weight, responsiveness, and overall playing feel.
Yamaha YDP-145
The Yamaha YDP-145 uses Yamaha’s Graded Hammer Standard (GHS) action, a well-established technology found in many of their entry-level and mid-range digital pianos. GHS is designed to mimic the heavier feel of the lower keys (bass notes) and the lighter touch of the upper keys (treble notes), a characteristic of acoustic pianos. While not as advanced as Yamaha’s GH3 or NWX actions found in higher-end models, GHS provides a reliable and enjoyable playing experience, particularly for beginners.
Key Material and Texture
The keys on the YDP-145 are made of plastic, with a matte finish on the black keys to reduce slipperiness during extended playing sessions. While the white keys are smooth, they do not have the synthetic ivory or ebony feel found in higher-tier models. For beginner to intermediate players, the key surfaces are adequate and provide a consistent touch. However, more experienced pianists might find the lack of textured keys less satisfying, particularly during fast or complex passages where grip and tactile feedback become more critical.
Weighting and Action Mechanism
The GHS action is Yamaha’s most lightweight hammer-action mechanism, making it particularly appealing to new players who may not yet have the finger strength to handle the heavier resistance of higher-end actions. The keys respond well to gentle playing, making it easy for beginners to achieve a pleasing sound without feeling fatigued. However, this lighter weighting can feel less authentic for advanced players accustomed to the resistance of an acoustic piano.
The action mechanism itself is smooth and consistent across the keyboard, with no noticeable noise during operation. While the GHS action captures the essentials of weighted playing, it lacks the refined escapement simulation found in more advanced models or even in competing entry-level pianos like the Kawai KDP-120. The absence of escapement—an essential part of an acoustic piano’s mechanism that allows a key to be struck repeatedly before fully returning—may make the action feel less realistic during intricate, repeated note playing.
Responsiveness and Dynamics
The YDP-145 offers good dynamic control for an entry-level instrument. Beginners will appreciate its forgiving touch, while intermediate players can still explore a range of dynamics, from pianissimo to fortissimo. That said, players transitioning from an acoustic piano may find the GHS action somewhat lacking in nuance and depth, particularly in how it translates the subtlest variations in touch into sound.
Kawai KDP-120
The Kawai KDP-120 features Kawai’s Responsive Hammer Compact (RHC) action, a system specifically developed for the brand’s entry-level digital pianos. RHC is widely regarded as one of the best hammer-action mechanisms in this price range, offering a more refined playing experience that closely emulates an acoustic piano. Kawai has leveraged its expertise in acoustic piano manufacturing to create a digital counterpart that captures many of the same characteristics.
Key Material and Texture
The keys on the KDP-120 are also made of plastic, but Kawai’s attention to detail is evident in the texture and feel. The black keys have a matte finish similar to Yamaha’s, but they feel slightly smoother, which might be a matter of personal preference. Where the KDP-120 shines is in the overall tactile feedback of the keys. While the white keys lack the synthetic ivory texture of Kawai’s higher-end models, the key surfaces feel solid and refined, offering a premium touch for its price range.
Weighting and Action Mechanism
Kawai’s RHC action replicates the graded weighting of an acoustic piano with remarkable accuracy. Like Yamaha’s GHS system, the lower keys are heavier, and the higher keys are lighter. However, the RHC action features a more balanced weighting across the keyboard, making it feel closer to an acoustic instrument. The weighting is slightly heavier than Yamaha’s GHS, which may require a bit more effort for beginners but offers greater realism for experienced players.
One standout feature of the RHC action is its use of counterweights within the keys to improve balance and control during soft playing. This adds a level of refinement that is absent in Yamaha’s GHS system. Additionally, the action incorporates a basic form of escapement simulation, allowing for a more authentic experience when playing repetitive notes or performing advanced techniques.
The RHC mechanism is also quieter than Yamaha’s GHS, which can be an important consideration for players practicing in shared or quiet environments. The smoothness and consistency of the action make it a joy to play, particularly for those focusing on expressive or technical repertoire.
Responsiveness and Dynamics
The KDP-120 excels in translating the player’s touch into sound. The keys respond with a level of precision that is rarely seen in this price category. Whether playing softly or with force, the RHC action captures the nuances of the player’s intent and translates them into the piano’s sound engine with remarkable fidelity. For intermediate and advanced players, this added layer of expressiveness makes the KDP-120 a more satisfying instrument to play.

The YDP-145’s tone is defined by its brightness and clarity. When playing with light to moderate dynamics, the sound is sharp and crisp, cutting through with a sparkling quality. This can be particularly appealing for players who enjoy a vivid and articulate sound. However, this brightness might not appeal to everyone. Some players, particularly those who prefer warmer or darker tones, may find the Yamaha’s sound slightly too sharp or metallic at times.
The tonal balance across the keyboard is excellent. The bass notes are clean and resonant, while the treble notes maintain clarity without becoming shrill. However, the midrange can feel slightly underwhelming compared to the bass and treble, which could detract from the overall tonal richness.
Sound Engine and Technology
The CFX sound engine incorporates Virtual Resonance Modeling Lite (VRM Lite), which simulates the natural resonance of strings and the soundboard in an acoustic piano. This adds a level of realism to the playing experience, as the sound changes depending on how the keys are played. VRM Lite also replicates the sympathetic vibrations that occur when the damper pedal is used, creating a more immersive sound.
However, VRM Lite is a scaled-down version of the full VRM technology found in Yamaha’s higher-end models, which means it lacks some of the more detailed resonance effects. While it’s a welcome inclusion at this price point, it doesn’t quite match the realism of Kawai’s Harmonic Imaging technology.
The YDP-145 offers 192-note polyphony, which ensures that complex pieces with sustained notes and overlapping pedal use are played smoothly. This is sufficient for most players, including those practicing classical repertoire or intricate arrangements.
Additional Voices
In addition to the main piano tone, the YDP-145 provides 10 other voices, including electric pianos, organs, strings, harpsichord, and vibraphone.

- Lesson Mode: The YDP-145 comes with 50 built-in classical piano songs and supports Yamaha’s educational “Lesson Function.” This mode breaks songs into left-hand and right-hand parts, allowing learners to practice hands separately. While this is a great feature for beginners, it lacks the customization and app-based interactivity found in Kawai’s Virtual Technician.
Voice Selection
The YDP-145 offers a modest selection of 10 voices, which include:
- CFX Grand Piano
- Electric Pianos (2 variations)
- Organs (2 variations)
- Strings
- Harpsichord
- Vibraphone
- A synthesizer tone
These voices are designed for variety, but the limited selection may feel restrictive for players who want to explore a broader palette of sounds. The quality of the voices is solid, particularly the CFX Grand Piano and strings, but the remaining tones, such as the harpsichord and electric pianos, are less impressive.
Advanced Features
One of Yamaha’s standout features is integration with the Smart Pianist app. This app allows players to select voices, adjust settings, and even display sheet music on a connected mobile device. The app’s intuitive interface is a great tool for beginners and tech-savvy users, offering easy access to a wealth of features.
However, the YDP-145 lacks Bluetooth connectivity, which means that Smart Pianist requires a wired connection. This limitation reduces the convenience of app usage compared to the Kawai KDP-120, which offers wireless Bluetooth MIDI.
Kawai KDP-120
The KDP-120 shines in its versatility and the depth of its features. While it is also an entry-level digital piano, Kawai has equipped it with a suite of tools and functions that cater to both beginners and intermediate players, offering a more customizable and immersive experience.
Modes
Like the Yamaha, the KDP-120 offers Dual Mode and Duo Mode, but it goes one step further with additional capabilities:
- Four Hands Mode: This mode is similar to Yamaha’s Duo Mode but allows for even more flexibility in splitting the keyboard for duets. It’s particularly useful for lessons or performances that require precise collaboration.
- Layering and Splitting: While Yamaha offers basic layering, the KDP-120 allows for more nuanced control over voice combinations, making it ideal for creating complex arrangements or experimenting with different sound textures.
Practice Tools
The KDP-120 includes a variety of built-in practice tools that make it an excellent choice for learners:
- Metronome: Like the Yamaha, the KDP-120 features a metronome with adjustable tempo and time signature settings, which are essential for rhythm training.
- Lesson Songs: The KDP-120 comes preloaded with Alfred’s Basic Piano Library lesson songs and other exercises, making it a fantastic choice for students following this curriculum. The lesson mode allows learners to practice hands separately, similar to Yamaha’s feature.
- Recording Functionality: The KDP-120 offers a more advanced recording function with up to three tracks. This allows users to create richer arrangements and layer multiple parts, making it ideal for practice or composition.
Voice Selection
The KDP-120 includes 15 high-quality voices, offering more variety than the Yamaha:
- Shigeru Kawai SK-EX Grand Piano
- Kawai EX Concert Grand Piano
- Upright Pianos
- Electric Pianos (multiple variations)
- Organs
- Strings
- Harpsichord
- Vibraphone
- Choirs
The standout feature here is the inclusion of two grand piano voices: the Shigeru Kawai SK-EX and the Kawai EX. These voices are distinctly different, offering players a choice between a warmer, richer tone and a brighter, more concert-like sound. Additionally, the electric pianos and strings are more detailed and expressive than those on the Yamaha YDP-145.
Advanced Features
The KDP-120 integrates seamlessly with Kawai’s Virtual Technician app, which provides a wide range of customization options. Using this app, players can adjust parameters like damper resonance, key-off noise, and touch sensitivity. This level of control allows players to tailor the sound and response of the instrument to their preferences, which is particularly appealing for intermediate or advanced users.
One of the most notable advantages of the KDP-120 is its Bluetooth MIDI functionality.

Connectivity
Connectivity is an essential aspect of modern digital pianos, particularly as musicians increasingly rely on apps, external devices, and software to enhance their practice and performance. The Yamaha YDP-145 and Kawai KDP-120 both offer standard connectivity options, but their implementations differ significantly. This section explores their ports, MIDI functionality, Bluetooth integration, and app compatibility to determine which piano offers the best options for seamless interaction with external devices.
Yamaha YDP-145
The Yamaha YDP-145 includes basic connectivity features that are sufficient for most beginner and intermediate players. While its options are functional and reliable, they lack the flexibility and modern wireless features seen in some competitors.
USB to Host (MIDI Functionality)
The YDP-145 features a USB-to-Host port, which allows it to connect directly to a computer, tablet, or smartphone. This is the primary way to use the piano as a MIDI controller for recording or interacting with apps like Yamaha’s own Smart Pianist. With this connection, users can access various software tools for learning, recording, and creating music. The USB-MIDI functionality is plug-and-play, meaning it doesn’t require additional drivers for most devices, making it straightforward for beginners to set up.
However, the lack of Bluetooth MIDI limits the convenience of this connection. Players need to use a physical cable, which can be cumbersome, especially if the piano is positioned far from the connected device. While this won’t bother everyone, those who prefer a cleaner, wireless setup might find this limitation frustrating.
Headphone Jacks
The YDP-145 is equipped with two headphone jacks (6.35mm), which are invaluable for quiet practice sessions or duets. These allow players to practice without disturbing others, making it ideal for home use in shared spaces. The dual jacks are a thoughtful inclusion for teacher-student setups, enabling both parties to listen through headphones during lessons. However, Yamaha does not include smaller 3.5mm adapters, which means you’ll need appropriate headphones or an adapter for use with standard consumer models.
App Integration: Smart Pianist
One of Yamaha’s standout features is its Smart Pianist app, which provides a user-friendly interface for accessing piano settings, selecting voices, and even displaying sheet music. The app is compatible with both iOS and Android devices, though connecting requires a wired USB connection. Smart Pianist also includes a unique “Audio to Score” feature that analyzes songs in your music library and generates chord progressions, a valuable tool for players who enjoy learning contemporary songs by ear.
While Smart Pianist is intuitive and powerful, the lack of wireless connectivity slightly hampers its usability. Players must manage cables when connecting their devices, which detracts from the otherwise seamless app experience.
Kawai KDP-120

With Bluetooth MIDI, players can connect their KDP-120 to Kawai’s Virtual Technician app, as well as third-party apps like GarageBand or Simply Piano, without the need for cables.
This wireless connectivity makes the KDP-120 far more versatile in modern setups, eliminating the clutter and restrictions associated with physical cables. It also simplifies integration with mobile devices, as users can adjust settings, record performances, or explore lessons from anywhere within Bluetooth range.
Headphone Jacks
The KDP-120 also includes two headphone jacks (6.35mm), mirroring the Yamaha in this regard. This feature is equally beneficial for quiet practice and duets. The inclusion of two jacks ensures that teachers and students can collaborate effectively during lessons without disturbing others in the household. However, like Yamaha, the KDP-120 does not offer smaller 3.5mm jacks or adapters, which may require additional purchases for use with standard headphones.
App Integration: Virtual Technician
Kawai’s Virtual Technician app sets the KDP-120 apart in terms of customization and functionality. This app allows players to adjust a wide range of piano parameters, including:
- Damper resonance
