❌ Not ideal for performance settings
Because the speakers are placed inside the casing, the DEP-20’s sound doesn’t disperse as naturally as an acoustic piano.
Yamaha P-145: Softer but Better-Projected Sound
✔️ Even sound projection—fills a small room well
✔️ No harsh frequencies or distortion
❌ Not as loud as the DEP-20
Though quieter, the P-145’s sound projects more evenly, making it feel more like a real piano in a room.
Winner (Volume & Projection): Yamaha P-145
While the DEP-20 is louder, the P-145’s balanced projection makes it sound more like an acoustic piano.
4. External Amplification Options
If built-in speakers aren’t enough, both models allow you to connect to external speakers or amplifiers.
| Model | Audio Outputs |
|---|---|
| Donner DEP-20 | ¼-inch stereo output |
| Yamaha P-145 | ¼-inch stereo output |
✔️ Both models can be amplified for better performance sound
✔️ Connecting to external speakers significantly improves both models
If you plan to perform or practice in larger spaces, adding external speakers will greatly enhance both pianos.
Final Verdict on Speaker System
| Category | Winner | Reason |
|---|---|---|
| Speaker Power | Donner DEP-20 | Louder (50W vs. 14W) |
| Sound Clarity | Yamaha P-145 | More natural, balanced frequency response |
| Projection | Yamaha P-145 | Sound fills the room more evenly |
| External Amplification | Tie | Both models offer ¼-inch outputs |
Final Winner: Yamaha P-145
While the Donner DEP-20 is louder, the Yamaha P-145 provides a better overall listening experience due to its clearer sound, more natural frequency balance, and better projection.
If you need raw volume, the DEP-20 is the better choice. But if you want a more authentic piano sound, the P-145 is the clear winner.
Features & Functions
When choosing a digital piano, features matter. Whether you’re a beginner wanting learning tools or a more experienced player who values customization, having the right set of features can dramatically affect how useful and enjoyable the piano is.
The Donner DEP-20 and Yamaha P-145 take very different approaches. One is packed with extras, the other is laser-focused on essentials. Let’s break down what each piano brings to the table across these categories:
- Voices and instrument sounds
- Modes (dual, split, layer, duo)
- Built-in rhythms and accompaniments
- Recording and playback functions
- User interface and controls
- Onboard effects
- Pedal support
1. Voices and Instrument Sounds
Donner DEP-20: 238 Tones
One of the DEP-20’s biggest selling points is its massive bank of 238 built-in tones. This includes everything from:
- Acoustic and electric pianos
- Organs, strings, brass
- Synths, bass, guitars
- Percussion instruments
For beginners or casual players, this can be fun. It lets you explore and experiment with different sounds without needing external software or MIDI packs.
Pros:
✔ Huge variety of tones
✔ Great for experimentation
✔ Fun for kids and beginners
Cons:
❌ Inconsistent quality — some tones are noticeably low quality
❌ Most non-piano tones won’t be useful for serious practice
Yamaha P-145: 10 Tones
Yamaha goes in the opposite direction. The P-145 includes just 10 carefully curated sounds, such as:
- Two grand piano voices
- Electric piano
- Harpsichord
- Strings
- Vibraphone
- Pipe organ and jazz organ
Each sound is clean, usable, and well-sampled. But there’s no fluff or extras.
Pros:
✔ High-quality samples
✔ Easy to navigate
✔ Focused on what players actually use
Cons:
❌ Limited sound variety
❌ Not as fun for non-piano experimentation
Winner (Voices): Donner DEP-20 (for quantity), Yamaha P-145 (for quality)
If you want to explore 200+ sounds, the DEP-20 is the obvious choice. But if you just need great piano and a few extras, the P-145 keeps it clean and focused.
2. Playing Modes
These include dual mode (layering sounds), split mode (different sounds in each hand), and duo mode (splitting the keyboard into two identical zones).
| Mode | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Dual (Layer) | ✅ | ✅ |
| Split | ✅ | ❌ |
| Duo | ✅ | ✅ |
Donner DEP-20: Fully Loaded The DEP-20 includes all three modes:
- Dual: Layer strings with piano, etc.
- Split: Piano in the right hand, bass in the left—great for jazz or accompaniment
- Duo Mode: Handy for teacher-student lessons
Yamaha P-145: Minimalist The P-145 offers dual and duo, but not split mode. This won’t bother classical players, but it’s a limitation for those who want more creative flexibility.
Winner (Modes): Donner DEP-20
The DEP-20 offers all major modes. Yamaha’s omission of split mode is a minor drawback depending on your style.
3. Built-in Rhythms & Accompaniments
Donner DEP-20: 100+ Rhythms
The DEP-20 includes numerous rhythm styles—from pop and rock to Latin and jazz. These rhythms are tempo-adjustable and can be fun for practice or casual jamming.
Pros:
✔ Adds variety to practice
✔ Great for improvisation
✔ Useful for basic songwriting demos
Cons:
❌ Quality of rhythms is hit or miss
❌ No intelligent accompaniment or chord detection
Yamaha P-145: None
Yamaha keeps it simple—there are no built-in rhythms. It’s clear the P-145 is made for focused piano playing, not general music experimentation.
Winner (Rhythms): Donner DEP-20
If backing rhythms are your thing, the DEP-20 has the edge. The P-145 doesn’t try to compete here.
5.4. Recording & Playback Functions
Donner DEP-20: Basic Internal Recording
You can record your performance directly on the DEP-20 and play it back later. It’s a single-track recorder—nothing fancy—but handy for checking your progress.
Pros:
✔ Useful for students
✔ Built-in, no extra equipment needed
Cons:
❌ No layering or multi-track recording
❌ Can’t export recordings easily
Yamaha P-145: No Internal Recorder
The P-145 does not have built-in recording. To record, you’ll need to connect it to a DAW or an external audio interface via USB.
Winner (Recording): Donner DEP-20
For casual recording without a computer, the DEP-20 wins. But if you’re recording professionally, you’ll probably be using a DAW anyway—where both work fine.
5. Onboard Effects
| Effect Type | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Reverb | ✅ | ✅ |
| Chorus | ✅ | ❌ |
| Adjustable | Partially | No |
Donner DEP-20: Basic Effects Included
The DEP-20 lets you adjust reverb and chorus levels to shape your sound a bit. Not studio-grade effects, but they add some life to the tones.
Yamaha P-145: Clean, Limited Effects
Yamaha includes reverb only, with several types to choose from. There’s no chorus, delay, or other effects.
Winner (Effects): Donner DEP-20
Again, Donner wins on versatility. Yamaha keeps things minimal but polished.
6. User Interface & Controls
Donner DEP-20: Screen + Buttons
It includes a small LCD display and dedicated buttons for modes, tones, rhythms, and functions. This makes it easier to navigate the DEP-20’s many options.
Pros:
✔ Visual feedback via screen
✔ Direct access to most features
Cons:
❌ UI feels a bit cheap
❌ Menu navigation can get clunky
Yamaha P-145: Button-Based Simplicity
The P-145 ditches the screen entirely. It uses button combos with LED indicators. This works well if you know your way around, but there’s a learning curve.
Pros:
✔ Clean and uncluttered layout
✔ Great once you memorize functions
Cons:
❌ Steeper learning curve
❌ No display = trial-and-error at first
Winner (Interface): Donner DEP-20
If you like a visual display, the DEP-20 is easier to use out of the box. Yamaha’s interface is elegant but less beginner-friendly.
7. Pedal Support
Donner DEP-20: 3-Pedal Unit Available
You can use the included sustain pedal or buy a separate triple pedal unit (if using with Donner’s furniture stand). The support for soft, sostenuto, and sustain is a plus.
Yamaha P-145: Half-Damper Support
Yamaha includes a basic sustain pedal, but it supports half-damper functionality (if upgraded to Yamaha’s FC3A pedal). This gives you more nuanced pedal control—a huge bonus for advanced players.
Winner (Pedal Support): Yamaha P-145 (for nuance), Donner DEP-20 (for triple pedal)
DEP-20 offers three pedals with its furniture stand. But Yamaha’s half-damper support is a game-changer for more expressive control.
Final Verdict on Features & Functions
| Category | Winner |
|---|---|
| Instrument Voices | Donner (quantity), Yamaha (quality) |
| Modes (Split/Layer/Duo) | Donner |
| Rhythms & Accompaniments | Donner |
| Recording | Donner |
| Effects | Donner |
| User Interface | Donner |
| Pedal Support | Tie (Donner for 3 pedals, Yamaha for half-damper) |
Overall Winner: Donner DEP-20 (Feature-Rich), Yamaha P-145 (Minimalist Pro)
The Donner DEP-20 wins for features—no question. It’s loaded. If you want lots of voices, built-in rhythms, easy recording, and all the extras, it’s a great value.
But the Yamaha P-145 offers high-quality, essential features only. If you don’t care about flashy extras and just want a streamlined, serious digital piano that does the fundamentals beautifully, Yamaha’s approach may appeal more.
Connectivity
Connectivity might not be flashy, but it’s essential. In 2025, digital pianos don’t just stand alone—they often serve as the center of a larger musical setup: connecting to recording software, MIDI controllers, learning apps, external speakers, and more.
Some players want to record into a DAW. Others want to practice silently with headphones. Some need Bluetooth. And some just want to plug into a speaker for a casual living-room performance. Let’s break down what the Donner DEP-20 and Yamaha P-145 offer—and where they fall short.
We’ll look at:
- Audio outputs
- Headphone jacks
- USB/MIDI connections
- Bluetooth capability
- App integration
- External pedal support
- Use in performance or recording setups
1. Audio Outputs
Both digital pianos include line outputs, which let you connect to amplifiers, speakers, mixers, or audio interfaces.
| Feature | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Line Out | ✅ (1/4” stereo) | ✅ (1/4” stereo shared with headphone jack) |
Donner DEP-20: Separate 1/4” Line Out
The DEP-20 includes a dedicated stereo 1/4” line out, which is ideal for connecting to powered speakers, PA systems, or an audio interface for live gigs or studio sessions.
✅ Pros:
- Clean, direct connection to external audio gear
- Doesn’t interfere with headphone use
- Useful for small venues or home studios
❌ Cons:
- Slight background noise at high volumes (noticeable with cheap cables)
Yamaha P-145: Dual-Purpose Jack
The P-145 doesn’t have a separate line out. Instead, it uses the same 1/4” jack for both headphones and line-level output. It works fine, but this dual function means:
✅ Pros:
- Simplifies the interface
- Still works well with speakers or interfaces
❌ Cons:
- You can’t plug in headphones and speakers simultaneously
- Not ideal for permanent studio setups
Winner: Donner DEP-20
The DEP-20’s dedicated line output gives it a slight edge for performers or studio users.
2. Headphone Jacks
Practicing with headphones is a must-have feature for many players, especially in apartments or shared spaces.
| Feature | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Headphone Jacks | ✅ (1/4” + 1/8”) | ✅ (2 x 1/4”) |
Donner DEP-20: Dual Size Ports
Donner includes both a 1/4-inch and 1/8-inch headphone jack, making it super convenient. No adapter needed, whether you’re using studio headphones or cheap earbuds.
👍 Nice touch for beginners or people who don’t have pro gear.
Yamaha P-145: Twin 1/4-Inch Jacks
Yamaha includes two 1/4-inch headphone jacks. This is excellent for duet practice or teacher-student settings.
However, no 1/8-inch mini jack means you’ll need an adapter for typical consumer headphones.
Winner: Tie
Donner is more flexible with jack sizes. Yamaha is better for dual headphone use. Choose based on your gear.
3. USB/MIDI Connectivity
In a world full of music production software, MIDI connectivity is essential for anyone who wants to:
- Use learning apps like Flowkey, Simply Piano, or Piano Marvel
- Record MIDI in a DAW (Ableton, Logic, FL Studio, etc.)
- Control virtual instruments (VSTs)
- Customize playback and learning tools
| Feature | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| USB to Host (MIDI over USB) | ✅ | ✅ |
| Traditional MIDI Ports | ❌ | ❌ |
| USB Audio | ❌ | ✅ |
Donner DEP-20: USB MIDI Only
The DEP-20 includes USB to Host, so you can connect it to a computer and control virtual instruments or learning software.
But it does not transmit audio—you’ll need an external audio interface to record actual sound.
Yamaha P-145: USB MIDI + USB Audio
The big win for Yamaha here is that the P-145 supports USB audio. This means you can connect it to your DAW with a single USB cable and record both MIDI and audio—no need for a separate interface.
✅ Perfect for creators and streamers.
✅ Works with iOS/Android via adapters, too.
Winner: Yamaha P-145
The addition of USB audio over USB is a game-changer for content creators and home recording setups.
4. Bluetooth Connectivity
| Feature | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Bluetooth MIDI | ❌ | ✅ (via Smart Pianist app) |
| Bluetooth Audio | ❌ | ❌ |
Donner DEP-20: No Bluetooth
The DEP-20 doesn’t include any Bluetooth functionality. All connections are wired. If you want to use a mobile app or control software, you’ll need a USB cable and potentially an adapter for tablets or phones.
Yamaha P-145: Bluetooth MIDI (With Optional Adapter)
Out of the box, the P-145 doesn’t have built-in Bluetooth. However, with the optional Yamaha UD-BT01 or MD-BT01 adapter, you can connect to apps like Yamaha’s Smart Pianist wirelessly.
This gives you wireless control over:
- Voice selection
- Metronome and tuning
- Settings and EQ
- Sheet music and backing tracks
👍 This adds a modern touch, especially useful during practice.
Winner: Yamaha P-145 (With Adapter)
It requires extra gear, but Yamaha’s Bluetooth MIDI support makes it more future-proof.
5. App Integration & Smart Features
Donner DEP-20: No App Support
Donner doesn’t have a companion app or software integration. You can still use third-party apps like Simply Piano or Flowkey via USB, but there’s no custom interface for controlling the instrument or navigating features.
Yamaha P-145: Works with Smart Pianist App
With Yamaha’s Smart Pianist app (iOS and Android), you can:
- Adjust reverb and volume levels
- Change voices
- Practice with built-in scores
- See a visual representation of the keyboard
- Load sheet music or play along with songs
Even though it’s a basic piano, this app adds serious value. It’s one of the easiest ways to control a digital piano using your phone or tablet.
Winner: Yamaha P-145
App integration takes Yamaha to the next level for beginners and tech-savvy players.
6. Pedal & Stand Connectivity
| Feature | Donner DEP-20 | Yamaha P-145 |
|---|---|---|
| Sustain Pedal Jack | ✅ | ✅ |
| 3-Pedal Unit Support | ✅ (via proprietary port) | ✅ (with optional stand) |
Both pianos support:
- A standard sustain pedal
- A 3-pedal unit when mounted on their compatible furniture stands
Yamaha’s triple pedal setup is a bit more refined, offering half-pedaling support if you pair it with the FC3A pedal.
Winner: Tie
Both offer standard pedal expandability. Yamaha has more nuanced control; Donner includes more basic triple pedal features.
7. Use in Studio or Live Settings
Donner DEP-20: ✅ Decent for casual gigs thanks to the line out
✅ Basic USB MIDI support for DAWs
❌ No USB audio
❌ No Bluetooth
❌ No app integration
Yamaha P-145: ✅ USB MIDI + USB audio = smoother DAW workflow
✅ Clean interface for small gigs
✅ App integration adds control
✅ Better with Yamaha’s FC3A and furniture stand
❌ No dedicated line out (shared jack only)
Final Verdict on Connectivity

| Pedal Support | Tie |
| Recording Setup Compatibility | Yamaha P-145 |
Overall Winner: Yamaha P-145 (for modern users and creators)
If you just want to plug and play, both work fine. But if you’re building a tech-savvy setup—recording, app usage, mobile control—the P-145 gives you more flexibility, even if it needs a few optional extras.
That said, if you’re on a tight budget or just want simple wired connections, the Donner DEP-20 gives you a lot for the price.

Value for Money
When it comes to buying a digital piano, value for money isn’t just about the price tag—it’s about how much quality, performance, and long-term satisfaction you get for every dollar spent. The Donner DEP-20 and Yamaha P-145 both cater to budget-conscious buyers, but they go about it in different ways.
Let’s dig into what each model offers for the price—and whether you’re actually getting a good deal.
Price Range
At the time of writing:
- Donner DEP-20 typically sells for $300–$400, often including a bench, stand, sustain pedal, and sometimes headphones.
- Yamaha P-145 is priced around $500–$650, with the basic package including just the piano and a footswitch-style sustain pedal. A bundle with a stand and proper pedal unit can push it closer to $800+.
So, at a glance, the Donner is significantly cheaper—but price alone doesn’t tell the full story.
Donner DEP-20: Strong Specs for a Low Price
The DEP-20 is aggressively priced for what it offers:
- 88 hammer-action keys
- 238 built-in voices
- Dual headphone jacks
- Dedicated line out
- MIDI over USB
- Basic triple pedal compatibility
- Full stand and accessories included
On paper, it looks like a steal. And honestly, for a beginner or someone who wants to test the waters with piano playing, it’s hard to argue with what you’re getting. The feel, the look, and the features all punch above its price point—especially when you factor in the accessories.
But there’s a catch: the build quality, key action, and sound engine don’t hold up under close scrutiny. Once you gain experience or start playing more frequently, you’ll notice:
- The keys don’t respond as naturally as higher-end models
- The sound lacks dynamic nuance
- Some functions feel clunky or cheaply implemented
That doesn’t make it a bad piano—it just means you might outgrow it quickly if you get serious.
✅ Who it’s great for:
- Beginners on a tight budget
- Parents unsure if their kid will stick with lessons
- Casual players who don’t need pro-level nuance
- People wanting lots of features and sounds to experiment with
Yamaha P-145: Higher Cost, Longer-Term Payoff
The Yamaha P-145 is more expensive, no doubt. And yes, it gives you less in terms of included extras (stand, bench, pedals). But what you do get is better built, more refined, and more reliable.
For the extra money, you’re getting:
- Graded Hammer Compact (GHC) key action that’s closer to an acoustic piano
- High-quality piano tone from the CFIIIS sampling engine
- USB audio and MIDI
- App integration with Smart Pianist
- Proven Yamaha reliability and long-term support
The P-145 is a more focused, better-executed instrument. It doesn’t overwhelm you with features—it prioritizes feel, sound, and consistency. The kind of instrument that makes practice more enjoyable, which leads to better progress.
✅ Who it’s great for:
- Beginners who want a more realistic acoustic experience
- Students planning to take lessons long-term
- Intermediate players looking for a compact, affordable practice piano
- Home users who want minimal setup fuss but good results
❌ Not ideal for:
- People who want flashy features or tons of built-in tones
- Buyers expecting a full bundle at this price
- Gigging musicians needing separate line outputs without adapters
Long-Term Perspective
The Donner DEP-20 is an incredible short-term deal, especially for beginners. But if you stick with piano playing for more than a year, you may find yourself wanting something with a better key feel and richer sound—meaning you might need to upgrade.
The Yamaha P-145, on the other hand, costs more up front but has a longer shelf life. You could easily use it for 3–5 years before feeling the need to step up to something like the P-225 or a mid-range console model. And for some hobbyists, it may be all they ever need.
Final Verdict on Value
| Piano | Strengths | Best For |
|---|---|---|
| Donner DEP-20 | Feature-packed, very affordable, lots of sounds | Beginners on a tight budget, casual players |
| Yamaha P-145 | Better touch and tone, more future-proof, USB audio | Students, serious beginners, long-term learners |
If budget is your #1 concern, the DEP-20 wins.
If you’re playing the long game, the P-145 is the better investment.
Let me know if you’d like a price comparison table or bundle suggestions added.
Final Verdict
Choosing between the Donner DEP-20 and the Yamaha P-145 comes down to priorities. These two digital pianos serve different types of users—and they do it well in their own lanes.
If you’re on a tight budget, new to piano, or buying an instrument to test the waters, the Donner DEP-20 offers a ton of features for the price. It’s hard to beat when it comes to the sheer amount of functions packed into an affordable package—hundreds of tones, built-in rhythms, a furniture-style stand, and dual headphone jacks. It feels generous. For casual players or parents unsure how long their kid will stick with lessons, this could be the sweet spot: low risk, high value.
That said, it’s clear that Donner made compromises to hit that price point. The key action is passable but not refined. The sounds are serviceable but lack dynamic depth. The overall feel is more “digital keyboard” than “piano.” You’ll outgrow it if you get serious about playing.
The Yamaha P-145, on the other hand, is all about quality where it counts. It doesn’t try to dazzle with features—it sticks to the essentials and does them well. The action is more realistic, the piano tone more expressive, and the build quality stronger. It’s also better integrated into modern workflows, with USB audio and app support. For students, teachers, and intermediate players, it’s a much more satisfying instrument over time.
So, who wins?
- Budget-conscious beginner? Go with the Donner DEP-20.
- Serious about learning and long-term playability? Choose the Yamaha P-145.
Both are solid choices—but they’re aimed at different journeys.
