Design & Build Quality
When it comes to digital pianos, design and build quality play a significant role, especially for home users and gigging musicians. While sound and keyboard action are the most critical factors in choosing an instrument, the overall aesthetic, durability, and user experience also matter.
The Donner DEP-20 and Donner SE-1 are both budget-friendly digital pianos, but they take slightly different approaches to design. Let’s analyze their appearance, build materials, weight, portability, controls, and overall feel to see which one stands out.
Aesthetic & Appearance
Donner DEP-20: A Classic Yet Basic Look
At first glance, the Donner DEP-20 looks like a traditional digital piano. It has a full-sized 88-key layout, a straight-edged design, and a black plastic casing that is fairly simple in appearance.
The control panel is located on the top of the piano, with a blue-backlit LCD screen in the center and a series of buttons and dials arranged on either side. While the screen is useful for navigating sounds and settings, the overall design feels somewhat dated.
The buttons and controls are functional but plasticky, and they don’t feel particularly premium. If you’re used to higher-end digital pianos with more refined control interfaces, the DEP-20 might feel a little cheap in comparison.
The piano also has a slightly thicker body, giving it a bulkier feel than some other budget models. While this isn’t a deal-breaker, it does make it less sleek and modern than the SE-1.
Donner SE-1: A More Refined, Modern Design
The SE-1, on the other hand, has a more modern, refined, and minimalistic aesthetic. Donner clearly designed this model to feel more premium, despite still being a budget-friendly instrument.
Instead of the boxy, plasticky look of the DEP-20, the SE-1 has a sleek, matte-finished exterior. The edges are smoother and thinner, giving it a more compact and contemporary feel.
One of the standout visual differences is the control panel. Instead of a large LCD screen surrounded by buttons, the SE-1 features touch-sensitive backlit buttons. This design gives it a cleaner, more high-end look compared to the traditional buttons on the DEP-20.
The backlit controls not only look better but also make it easier to see in low-light environments, which is a plus if you’re playing in a dimly lit room or stage.
Overall, if aesthetics matter to you, the Donner SE-1 is the clear winner.
Build Materials & Durability
Donner DEP-20: Sturdy but Plasticky
The DEP-20 is made entirely of plastic, which is common in budget digital pianos. The body is fairly sturdy, but the plasticky nature of the casing means it doesn’t feel as premium as some competitors.
The buttons and dials feel somewhat cheap and clicky, and over time, they may become less responsive with heavy use. The LCD screen, while useful, is not of the highest quality, and the interface feels outdated compared to modern touchscreens or LED interfaces.
That being said, the DEP-20 doesn’t feel fragile, and as long as you take care of it, it should last a good while. However, if you’re someone who moves your keyboard frequently, you may notice some wear and tear, particularly on the buttons and edges of the plastic casing.
Donner SE-1: A More Premium Feel
The SE-1, while still made primarily of plastic, has a noticeably better build quality than the DEP-20. The plastic is matte and textured, making it feel less cheap and more durable.
The backlit touch-sensitive buttons are a huge improvement. Not only do they look sleeker, but they also eliminate the issue of buttons becoming unresponsive over time.
Additionally, the SE-1’s overall structure is thinner and more compact, yet it feels sturdy and well-made. The keys also have a more solid feel (which we’ll discuss in more detail in the keyboard section), adding to the premium perception of the instrument.
While neither of these pianos can match the build quality of higher-end brands like Yamaha or Roland, the SE-1 definitely feels like the better-constructed model.
Weight & Portability
Donner DEP-20: Slightly Bulkier and Heavier
The DEP-20 weighs around 11kg (24 lbs), which is relatively lightweight for a full-sized digital piano but still a bit bulkier than necessary.
If you plan to keep it in one place, this isn’t an issue. However, if you travel with your keyboard or move it around frequently, you may find it a bit cumbersome compared to lighter models.
The thickness of the DEP-20 also makes it a less attractive option for portability, as it takes up more space and is slightly harder to handle.
Donner SE-1: More Portable and Lightweight
The SE-1 is noticeably lighter, weighing about 10kg (22 lbs). While the weight difference isn’t massive, the thinner design makes it much easier to carry and transport.
If you’re someone who takes your keyboard to gigs, rehearsals, or lessons, the SE-1 is the better choice simply because it is more compact and easier to move around.
Winner: SE-1 – If portability is important, the SE-1 is the clear winner due to its lighter weight and thinner design.
Control Interface & Buttons
Donner DEP-20: Basic but Functional
The DEP-20 has a traditional button-based control interface with a small LCD screen. While it gets the job done, the buttons feel cheap and somewhat outdated compared to modern digital pianos.
Navigating through menus is a bit clunky, and the button layout could be more intuitive. If you’re used to modern touch-sensitive controls, you might find the DEP-20’s interface a bit frustrating to use.
Donner SE-1: Backlit Touch Controls for a Modern Feel
The SE-1 significantly improves on the control experience by replacing plastic buttons with touch-sensitive backlit controls.
This change makes a huge difference in usability:
- More modern look and feel
- Easier to navigate in dark settings
- No risk of buttons wearing out over time
The touch-sensitive interface makes the SE-1 feel more premium, even though it’s still a budget-friendly digital piano.
Winner: SE-1 – The backlit touch controls make the SE-1 feel more modern and premium compared to the button-heavy DEP-20.
Final Thoughts on Design & Build Quality
After examining every aspect of design and build quality, it’s clear that the Donner SE-1 is the superior choice.

Keyboard & Key Action
One of the most crucial aspects of any digital piano is its keyboard and key action. After all, the way the keys feel under your fingers and how they respond to touch is what truly defines the playing experience.
For beginners, the keyboard action determines how realistic the transition from a digital piano to an acoustic piano will be. For intermediate and advanced players, key action affects technique, expression, and playability.
Both the Donner DEP-20 and the Donner SE-1 come with fully weighted, 88-key hammer action keyboards. However, while they seem similar on paper, their actual feel and response differ quite a bit. In this section, we’ll break down how these two keyboards compare in terms of key weight, responsiveness, realism, texture, and overall playing experience.
1. Key Weight & Realism
Donner DEP-20: Fully Weighted but a Bit Stiff
The DEP-20 features a fully weighted keyboard with hammer action, which is an essential feature for those who want a realistic piano feel. However, while the keys are indeed weighted, the action feels noticeably stiff compared to an acoustic piano.
When playing fast passages or softer dynamics, the keys don’t respond as smoothly as higher-end digital pianos. There is a slight heaviness that can make playing intricate pieces more tiring, especially for beginners who are still developing finger strength.
That being said, the key weight does provide a decent amount of resistance, which is good for building proper finger technique if you’re a beginner. The main issue is that the weighting isn’t as balanced across the entire keyboard. The lower keys feel heavier, while the higher keys feel slightly lighter, but the transition isn’t as gradual as it should be.
Another downside is that the keys rebound a bit slower than expected, meaning repeated notes (such as trills) can feel a little sluggish.
Donner SE-1: Improved, More Balanced Hammer Action
The SE-1 also features a fully weighted, 88-key hammer action keyboard, but it has a more refined key response compared to the DEP-20.
The biggest difference is in the balance of key weight. Unlike the DEP-20, where some areas feel heavier than others, the SE-1 offers a more consistent and natural weighting across the keyboard.
Additionally, the SE-1 has a slightly lighter touch, which makes it easier to play for extended periods without hand fatigue. The keys feel more responsive, allowing for better control over dynamics and articulation.
Repeated notes and trills feel more fluid, and fast passages are easier to execute. This makes the SE-1 a better choice for intermediate players who want a more realistic and expressive playing experience.
Winner: Donner SE-1
The SE-1 has better key balance, a smoother action, and improved responsiveness, making it the superior option.
2. Key Texture & Material
Donner DEP-20: Glossy Plastic Keys
One of the biggest downsides of the DEP-20’s keyboard is its key texture. The keys are entirely glossy plastic, which can feel slippery, especially after extended playing sessions.
If you’re someone who sweats while playing, you may find that your fingers slip more easily on these keys compared to matte or textured alternatives.
Another drawback is that the glossy plastic doesn’t feel as premium as the textured keys found on many other digital pianos. It’s a minor issue for beginners, but for those used to playing acoustic pianos or higher-end digital pianos, it’s a noticeable downgrade.
Donner SE-1: Semi-Matte, More Premium Key Texture
The SE-1 improves upon the DEP-20 by offering semi-matte keys, which provide a more realistic touch.
The semi-matte finish mimics the feel of real ivory/ebony keys found on acoustic pianos, making it more comfortable to play for extended periods. The texture helps prevent slipping, making it easier to maintain control over fast passages and soft playing.
Winner: Donner SE-1
The SE-1’s semi-matte key texture provides a better tactile experience and feels more premium compared to the DEP-20’s glossy plastic keys.
3. Touch Sensitivity & Dynamic Response
Donner DEP-20: Adjustable but Limited Sensitivity
The DEP-20 offers three levels of touch sensitivity (Soft, Medium, Hard), allowing users to adjust the response based on playing style.
However, while the sensitivity settings work, the overall dynamic range feels somewhat limited. When playing very softly, the sound doesn’t always register as gently as it should, and when playing forcefully, the volume increase isn’t as dramatic as on a real acoustic piano.
This can be frustrating for expressive playing, as it limits how naturally you can control dynamics.
Donner SE-1: More Expressive & Natural Sensitivity
The SE-1 also features adjustable touch sensitivity, but the key difference is that it responds more naturally to variations in touch.
The dynamic range is wider, allowing for greater control over soft and loud playing. Pianissimo passages feel more delicate, while forte passages sound more powerful and resonant.
This makes the SE-1 a better choice for players who want more expressive control over their music.
Winner: Donner SE-1
The SE-1’s touch sensitivity feels more natural, allowing for greater expression and dynamic control.
4. Key Noise & Mechanical Feel
Donner DEP-20: Slightly Noisy Key Action
One issue with the DEP-20’s keyboard is that the keys can be a bit noisy, especially when playing at lower volumes or using headphones. The mechanical action produces a noticeable clunky sound, which might be distracting for some players.
While it’s not a deal-breaker, it’s worth noting if you plan to play in quiet environments.
Donner SE-1: Quieter & Smoother Action
The SE-1’s keyboard action is quieter, reducing the clunky mechanical noise found in the DEP-20. This makes it better suited for practice in shared living spaces or late-night playing with headphones.

If you want a more realistic and enjoyable playing experience, the SE-1 is the superior choice.
Sound Quality & Polyphony
Sound quality is one of the most important aspects of any digital piano. While key action determines how it feels to play, the sound is what ultimately inspires you to keep playing. A great-sounding digital piano should offer realistic, rich, and expressive tones, allowing players to feel connected to their music.
Both the Donner DEP-20 and the Donner SE-1 provide a range of instrument voices, effects, and customization options. However, their sampling quality, polyphony, and tone realism vary significantly. In this section, we’ll break down their sound engines, compare their tones, and analyze how each piano handles sustain, layering, and dynamic expression.
1. Sound Engine & Sampling Quality
Donner DEP-20: Decent, but Somewhat Artificial Sound
The DEP-20 comes with 238 built-in instrument tones, including acoustic pianos, electric pianos, organs, strings, and various synth sounds. On paper, that sounds impressive, but more sounds don’t always mean better quality.
The acoustic piano tones, which are the most important for most players, are decent but not outstanding. The samples sound somewhat artificial, especially in the lower register, where the bass notes lack depth and richness.
One of the biggest issues is that the sustain and resonance feel slightly unnatural. On an acoustic piano, when you hold down the sustain pedal, the strings resonate with each other, creating a natural and immersive sound. The DEP-20 attempts to replicate this, but the result feels a bit static—notes don’t interact with each other as naturally as they would on an acoustic or higher-end digital piano.
Additionally, while the higher register sounds bright and clear, some notes feel harsh or thin, especially at higher velocities.
For casual players or beginners, the DEP-20’s sound is acceptable. However, for more advanced players who rely on detailed dynamics and expression, the sound can feel a bit limited and artificial.
Donner SE-1: Richer, More Natural Sound with Better Sampling
The SE-1 takes a noticeable step up in sound quality. It comes with 200 built-in tones, slightly fewer than the DEP-20, but the quality is noticeably better.
Instead of focusing on sheer quantity, Donner put more effort into the sampling and realism of the sounds. The acoustic piano samples in the SE-1 sound richer, more organic, and more detailed compared to the DEP-20.
One of the biggest improvements is in the low-end response. The bass notes sound fuller and warmer, making the overall playing experience more satisfying. The midrange is clearer, and the high-end is less harsh, making for a more balanced overall tone.
Another major advantage of the SE-1 is its resonance modeling. When playing with the sustain pedal, notes feel more connected and natural, unlike the more artificial sustain of the DEP-20. This makes legato playing and expressive phrasing much more satisfying.
In short, while the SE-1 doesn’t reinvent the wheel, its improved sampling and resonance modeling make it a much more enjoyable instrument to play.
Winner: Donner SE-1
The SE-1 provides a richer, more realistic sound engine, while the DEP-20 sounds more artificial in comparison.
2. Polyphony: How Many Notes Can It Handle?
Polyphony refers to the maximum number of notes a digital piano can produce at the same time. A higher polyphony count allows for richer, more complex sounds, especially when using sustain, layering, and dual voices.
Donner DEP-20: 128-Note Polyphony
The DEP-20 comes with 128-note polyphony, which is fairly standard for budget digital pianos.
For simple playing, 128-note polyphony is more than enough. However, if you start using sustain pedal, layered sounds, or complex passages, you might notice some note dropouts—especially when playing fast runs or dense chords.
For example, when holding a chord with the sustain pedal while playing melodic runs, some older notes may get cut off prematurely.
Donner SE-1: 128-Note Polyphony with Better Optimization
The SE-1 also offers 128-note polyphony, but there’s an important difference: the SE-1’s sound engine is optimized better.
In real-world playing, the SE-1 handles layering, sustain, and fast passages more efficiently than the DEP-20. Even though they have the same polyphony count, the SE-1’s superior sound engine makes better use of its resources.
This means that notes don’t drop out as quickly, making the playing experience smoother and more natural.
Winner: Donner SE-1
Both have 128-note polyphony, but the SE-1’s better optimization prevents dropped notes in complex passages.
3. Sound Customization & Effects
Donner DEP-20: Basic Customization & Effects
The DEP-20 includes a few basic effects like:
- Reverb (adds depth to the sound)
- Chorus (creates a richer, layered sound)
- EQ adjustments
While these features are nice, the control over effects is limited. You can adjust them, but you don’t get fine-tuned control over parameters like decay time or depth.
Donner SE-1: More Advanced Effects & Sound Shaping
The SE-1 offers better-quality effects and more control over customization. The reverb and chorus effects sound more natural, and there’s better control over EQ settings to tweak your sound.
Additionally, the SE-1 has more nuanced velocity sensitivity adjustments, allowing you to fine-tune the piano’s response to your touch.
Winner: Donner SE-1
The SE-1 offers better sound effects, more customization options, and improved reverb quality.
4. Instrument Voices & Variety
Donner DEP-20: 238 Tones (Quantity Over Quality)
The DEP-20 comes with 238 instrument tones, including:
- Grand pianos
- Electric pianos
- Strings
- Organs
- Synths
- Percussion sounds
While the variety is impressive, many of the tones sound artificial. The electric pianos and synths are usable, but the orchestral instruments and organs sound unrealistic.
Donner SE-1: 200 Tones (Fewer, but Higher Quality)
The SE-1 includes 200 tones, which is fewer than the DEP-20, but the quality is noticeably better. The piano, electric piano, and strings all sound more natural, making them more useful in actual playing.
Winner: Donner SE-1
Even though the DEP-20 has more voices, the SE-1 prioritizes quality over quantity.
Final Verdict: Which One Sounds Better?
| Feature | Donner DEP-20 | Donner SE-1 |
|---|---|---|
| Sound Engine | Decent, but slightly artificial | Richer, more natural tone |
| Polyphony | 128-note, but struggles with sustain | 128-note, better optimization |
