If you’re shopping for a beginner-friendly, budget-conscious digital piano with Yamaha’s trusted name behind it, two models will likely catch your eye: the Yamaha YDP-105 and the Yamaha P-145.
Both are entry-level 88-key digital pianos aimed at newcomers and casual players, but they take different approaches. One is built for the traditional furniture-style home setup (YDP-105), while the other is a compact, portable slab (P-145).
So which one is right for you? I’ve spent time testing both units and comparing them across design, feel, sound, features, and value. Here’s what I found.

Design & Build
When you’re deciding between two digital pianos in the same price range, design and build quality often carry more weight than you’d expect—especially if the instrument is going to live in your home for years. This is where the Yamaha YDP-105 and Yamaha P-145 start to show some real contrast. Though both are budget models, their designs serve two very different lifestyles: one is made to stay put and look like a traditional piano, while the other is built to move and adapt.
Let’s dig into each one in depth.
Yamaha YDP-105: Classic Home Piano Aesthetic
The YDP-105 belongs to Yamaha’s Arius line, which is essentially their entry-level digital piano range styled to resemble acoustic upright pianos. At a glance, it absolutely looks like a traditional piano. The structure includes a full-length stand with a sliding key cover, a built-in music rest, and a fixed three-pedal unit—all of which come pre-designed to work as one solid piece of furniture. This isn’t something you’ll fold up or toss in the back seat of a car.
When fully assembled, the YDP-105 measures 1357 mm wide, 815 mm high, and 422 mm deep (with the music rest). It weighs about 37.5 kg (82.7 lbs). That’s not back-breaking, but it’s a two-person job if you ever need to move it. The materials are a mix of engineered wood and plastic, typical of budget console models, but the finish is clean and well-executed.
You get a choice of two colors: dark rosewood and black. Both finishes are matte, not glossy, which helps hide fingerprints and minor scuffs. The design doesn’t scream “premium,” but it’s tasteful. The edges are soft and rounded, and the proportions are just right for a living room or home music nook. It won’t dominate a space, but it will look intentional—not like a gadget or a temporary fix.
The sliding key cover is a nice touch, protecting the keys from dust and adding to the upright-piano vibe. You don’t see this feature on portable models, and it adds a sense of permanence. The music rest is wide and sturdy enough for two sheets or a full-sized music book, which is great for students or anyone who uses printed scores.
The three pedals—sustain, sostenuto, and soft—are built into the cabinet. This adds realism for players who are used to acoustic pianos or who want to practice classical repertoire that calls for more nuanced pedal work. The pedals are metal, with a bit of resistance that mimics an upright feel. You won’t get that in entry-level portables without spending extra on pedal accessories.
From a durability standpoint, the YDP-105 feels stable. The full cabinet frame gives it a solid presence, and there’s no keyboard flex or rattling even when playing at high velocities. For families with kids, this is also a safer bet—it’s heavier, harder to knock over, and doesn’t move around with every bump.
That said, you are locked into a single-use case with the YDP-105: it’s a home piano. There’s no pretending it’s portable. Once you assemble it, it’s not going anywhere without tools and muscle.
Yamaha P-145: Modern Minimalism and Portability
The P-145 is the polar opposite in design philosophy. This is Yamaha’s latest iteration of a slab-style digital piano, meaning it’s essentially the keyboard itself, with optional accessories like a stand and pedals sold separately (or included in bundles).
At just 11.1 kg (24.5 lbs), the P-145 is incredibly lightweight for a full 88-key instrument with hammer action. Its dimensions—1326 mm wide, 129 mm high, and 268 mm deep—make it one of the slimmest digital pianos Yamaha has produced. The profile is almost startlingly thin when you first see it in person.
The design is minimalist, with a matte black finish and no unnecessary ornamentation. There’s no screen, no flashy LED panels, and just a few clearly labeled buttons along the left side for power, volume, and voice selection. The rest of the controls are accessed via key/button combinations, which takes a bit of memorization but keeps the aesthetic clean.
This piano is ideal for players who live in small apartments, dorm rooms, or shared spaces. It fits on a desk, table, or collapsible keyboard stand without taking over the room. You can stash it under a bed or in a closet when not in use, and it’s light enough to carry with one hand (or toss in a soft case for gigs and lessons).
The default music rest is a simple plastic slot-in piece that works well enough but feels noticeably more flimsy than the YDP-105’s integrated stand. It does the job but isn’t designed to impress.
One notable change over its predecessor, the P-45, is the P-145’s improved chassis. The body feels more rigid and less prone to creaking or flexing when played aggressively. Yamaha has clearly improved the internal frame design, despite using mostly plastic materials to keep the weight down.
However, since the P-145 doesn’t include a stand or pedals out of the box (unless you buy a bundle), you’re left to choose between Yamaha’s official accessories or cheaper third-party options. Yamaha offers the L-100 furniture-style stand and LP-5A three-pedal unit, which when combined, make the P-145 resemble a slim upright piano. But those accessories cost extra and push the total price up significantly.
If you’re okay with just a sustain pedal, the box-style FC5 footswitch is often included—but it’s a far cry from a real piano pedal. It’s small, plastic, and lacks half-pedal functionality.
One clever thing Yamaha did with the P-145 is keep it compatible with the Smart Pianist app. While this isn’t a physical design feature, it complements the piano’s modern, stripped-down build perfectly. Since the P-145 doesn’t have a display, using your phone or tablet to manage sounds, settings, and practice tools feels intuitive and natural.

Final Thoughts on Design
When choosing between these two, it really comes down to how and where you plan to use the piano.
If you want a digital piano that feels permanent, looks the part, and blends into a traditional or homey setting, the YDP-105 nails the brief. It’s a stable, well-built piece that acts as a centerpiece in any music room or living area. It has presence, form, and the tactile benefits of a built-in pedal unit.
If you live in a small apartment, travel frequently, or need a flexible setup for lessons, gigs, or practice on the go, the P-145 is the clear winner. Its sleek, lightweight build and minimalist design make it easy to carry, store, and integrate into different lifestyles. It might not impress visually like a full cabinet, but it’s modern, efficient, and far more versatile.
In short: form vs function. Aesthetics vs adaptability. It’s hard to go wrong with either, but the right choice depends entirely on how you plan to use it.
Keyboard Action & Feel
Let’s be real: no matter how sleek a piano looks or how many features it has, none of it matters if the keys feel like cheap plastic or the action is mushy. The keyboard action—how the keys respond under your fingers—is where a digital piano either wins or loses your trust. And when we talk about “feel,” we’re talking about more than just key weight. We’re talking about resistance, balance, return speed, surface texture, noise, and realism across the full range of dynamics.
Both the Yamaha YDP-105 and the Yamaha P-145 use Yamaha’s GHS (Graded Hammer Standard) key action, but the implementations are slightly different, and that difference is worth paying attention to—especially if you care about the subtle nuances of playing.
Understanding GHS: Yamaha’s Entry-Level Action
First, some context. GHS is Yamaha’s most basic fully weighted action. It’s been around for years and is designed to offer a simplified version of the “hammer feel” you get on an acoustic piano. Unlike semi-weighted keys, GHS uses actual mechanical weighting to simulate the feel of hammers striking strings. The keys are heavier in the low register and gradually get lighter as you move up—just like a real piano.
Now, this isn’t their premium action. Yamaha has several other key actions like GH (Graded Hammer), GH3, NWX, and GrandTouch, all of which offer better realism but at a higher price point. GHS is purely entry-level, but it does get the job done for most beginners and even some intermediate players.
So let’s break down how GHS is used in each model—and why the version in the P-145 may be a quiet game-changer.
Yamaha YDP-105: Classic GHS
The YDP-105 uses the original, time-tested GHS action. It’s the same mechanism Yamaha has used for years in models like the YDP-103, P-45, and even some older Clavinovas. And to its credit, it works.
The action is fully graded, meaning the lower notes do feel heavier than the higher ones. It’s not just a gimmick—you can feel the difference as you climb the keyboard. For new players, this is a big win. It helps develop finger strength and dynamic control, both of which are critical for translating your playing to an acoustic instrument later on.
The resistance is moderate—not too heavy, not too light. It doesn’t feel sluggish or rubbery like some cheaper alternatives from other brands. Fast passages and scales feel playable. Trills are possible, though maybe not as fluid as on Yamaha’s better actions like the GH3.
The downside? The key action is a bit noisy. Not obnoxiously so, but enough that you’ll hear the mechanical thud of keys returning—especially if you’re playing at night with headphones on. There’s also a slight plastic-on-plastic feel when keys bottom out, particularly if you play with force. It doesn’t feel bad, but it’s not exactly inspiring either. It’s a reminder that this is an entry-level action meant to keep costs down.
Key surfaces are smooth, plain plastic. No simulated ivory texture, no moisture absorption. During long practice sessions, this can make your fingers feel a little slippery—especially if your hands sweat. Yamaha adds textured keytops in their higher-end models, but not here.
The action overall is reliable, but you’ll definitely be aware that you’re playing a digital piano. It’s a solid platform for learning, but probably not something a picky pianist would love.
Yamaha P-145: GHS Compact – A Subtle But Real Upgrade
Here’s where things get more interesting.
With the P-145, Yamaha introduced a new version of GHS called GHS Compact. It’s still technically part of the GHS family, but the mechanism has been reengineered to fit into a slimmer chassis—and along the way, Yamaha managed to refine how it feels.
First off, the GHS Compact action is quieter. This is a small but meaningful win for people who practice late at night or use headphones. The key return noise has been dampened, and the bottoming out feels less plasticky compared to the original GHS. It’s not silent, but it’s a noticeable improvement.
The second thing you’ll feel right away is a slight increase in key responsiveness. The keys feel more balanced across the board. On older GHS versions (like in the YDP-105), the bass keys sometimes felt overly weighted, and the treble end could feel a little too light. With GHS Compact, the weight gradient still exists—but the transitions feel smoother and more natural.
The keys on the P-145 are still standard plastic—no synthetic ivory or wood grain—but the action itself feels more tightly built. There’s less key wobble, and the return spring has a faster snap to it. It’s subtle, but if you play them back to back, you’ll notice it.
This makes the P-145 more suited for faster playing, such as jazz, pop, or light classical. If you’re a beginner working on finger independence and control, GHS Compact gives you a slightly better platform to grow from. It’s easier to play softly, and easier to control dynamics because the key response is more even.
Some pianists have reported that the new GHS Compact has a slightly shorter key pivot length—meaning you may feel a tiny bit less leverage when playing near the backs of the keys. This is a trade-off Yamaha made to keep the P-145 thin. For most players, this isn’t a big deal, but more experienced pianists may pick up on it during intricate passages.
Playing Styles and Feel in Real Use
When comparing the two side-by-side, the difference is more in finesse than function. Both actions are capable of handling the same music. If you’re just practicing beginner material or intermediate-level classical, either one will serve you well.
But if you’re sensitive to touch, or play with a wide dynamic range, the P-145 gives you slightly more control. Pianissimo passages are easier to execute. Repeated notes feel snappier. There’s less of the sluggish bounce-back you get on older GHS actions.
However, for players who like a heavier, more deliberate feel—something with a little more “chunk” in the bass—the YDP-105 might feel more grounded. The extra depth of the cabinet and the weight of the unit give the keys a different physical feedback. Some players find this reassuring, even if it’s not technically more responsive.
The Role of Pedals in Feel
We can’t talk about touch without mentioning pedals, because they play a big part in how expressive a digital piano feels.
The YDP-105 comes with a built-in three-pedal unit, including half-pedaling support for the sustain pedal. This adds a layer of realism that’s useful for classical music and expressive play. The pedal travel feels close to that of a real upright—not perfect, but convincing enough.
The P-145, on the other hand, comes (usually) with a basic box-style footswitch called the FC5. It works for basic sustain, but that’s about it. If you want half-pedaling or a more realistic experience, you’ll need to spring for the FC3A pedal or the LP-5A triple pedal unit (which requires the L-100 stand).
In other words: the YDP-105 gives you full pedal realism out of the box. The P-145 can get there, but not without accessories.
Final Thoughts on Action & Feel
If you’re just starting out, both pianos will feel like a huge step up from unweighted keyboards or synth-action controllers. They provide the weight, resistance, and expressiveness needed to develop proper technique.
But if you’re choosing between the two based purely on feel, the P-145 and its GHS Compact action win out—just slightly. It’s not a night-and-day difference, but it is tighter, quieter, and more responsive, which makes it more enjoyable to play for long sessions or nuanced pieces.
On the other hand, the YDP-105 offers a more classic, grounded feel with a stable platform and integrated pedals—better if you’re after a more traditional experience without needing accessories.
Ultimately, it comes down to what kind of feel you prefer:
- The P-145 is modern, nimble, and a bit more refined.
- The YDP-105 is weightier, boxier, and more rooted in the “acoustic upright” mold.
Neither is perfect, but both are perfectly usable. For serious beginners or returning players, either one can be the right platform to grow your skills on.
Sound Quality & Voices
When it comes to digital pianos, sound is the soul of the instrument. It’s not just about how realistic the piano tone is—it’s about how it responds to your touch, how it fills a room, and how satisfying it is to play. The Yamaha YDP-105 and P-145 are entry-level models, so you won’t get the lush, multi-sampled engine from Yamaha’s high-end Clavinovas or the realism of the Bösendorfer samples found in their premium gear—but they still aim to offer a convincing, enjoyable playing experience. And while both pianos share the same core sound engine, how they deliver and shape that sound differs in small but important ways.
Let’s break it all down: the technology, the voices, the polyphony, and most importantly, how it all sounds in actual use.
AWM Stereo Sampling – The Shared Engine
Both the YDP-105 and the P-145 use Yamaha’s AWM Stereo Sampling technology, short for Advanced Wave Memory. This is Yamaha’s longest-running digital piano sound engine, and it’s the most basic one they offer. While “AWM” may sound fancy, in practice it means you’re getting stereo-recorded samples from a Yamaha acoustic grand piano, with a few layers of velocity to simulate dynamic expression.
There’s no physical modeling here. No advanced string resonance. No key-off samples. No simulated damper or cabinet resonance. You get a clean, solid piano tone—but without the extra nuance and realism of Yamaha’s CFX engine or Kawai’s Harmonic Imaging.
But let’s not be too quick to knock it. For the price point, the AWM samples still sound better than most beginner keyboards, especially through headphones or a good speaker system. The piano tone is bright and clear, with enough body to sound musical. It’s not the most expressive, but it gets the job done for practice, learning, and casual performance.
Piano Sound: Character and Response
So how does the main piano voice actually sound?
Both the YDP-105 and the P-145 feature two acoustic piano voices. The default Grand Piano 1 is the brighter, more defined tone. Grand Piano 2 is mellower, with less attack and a darker profile—useful for softer pieces or background play.
The tone of Grand Piano 1 is classic Yamaha: bright, focused, and slightly percussive. It’s the kind of sound that cuts through easily and works well for classical, pop, and rock. It doesn’t have the lush overtones of a Steinway or the warmth of a Bösendorfer, but it has clarity. And for beginners, clarity is good—it helps develop finger control and dynamic accuracy.
On both pianos, dynamics are handled with simple velocity-based sampling—press a key softly, and you get a quiet note; press harder, and the timbre brightens slightly. There are usually 3 to 4 layers of velocity, depending on the note, but transitions can be a little abrupt. Still, unless you’re an advanced player, this probably won’t bother you much. It’s playable, consistent, and musical.
Now here’s where some small differences come into play. Even though both pianos use the same samples, the YDP-105 tends to sound a bit fuller due to its cabinet design and speaker positioning. More on that in the speaker section, but the bottom line is: through internal speakers, the YDP-105’s piano tone feels more “complete” and resonant, while the P-145’s is a bit flatter and less spacious—especially at medium to high volumes.
Through headphones, however, the differences are minimal. In fact, some players prefer the P-145’s headphone tone, which feels slightly tighter and less boomy.
Polyphony – 64 Notes on Both
Both pianos offer 64-note polyphony. That’s decent, but nothing to brag about in 2025. You won’t run into issues while playing single pieces or even moderately complex classical works. But if you’re using the sustain pedal generously, or layering voices (like piano + strings), you may start to hear note cutoffs in dense passages.
Higher-end digital pianos now offer 192 or even 256-note polyphony, so 64 is definitely a limitation, but it’s one you can live with as a beginner or casual player. Just don’t expect to play Debussy with both hands and the sustain pedal down and keep every note alive.
The Voice Selection
Both the YDP-105 and P-145 include a total of 10 voices. The list is slightly rearranged between the two models but includes essentially the same sounds:
- 2 Grand Pianos
- 2 Electric Pianos
- 2 Organs (Pipe and Jazz)
- Strings
- Harpsichord
- Vibraphone
- Possibly a variation voice (depending on region/model)
These are basic but usable sounds. Let’s walk through a few:
Electric Pianos – These are FM-style and Rhodes-style pianos. EP1 has a bell-like, 80s DX7 tone. EP2 is rounder and warmer. Both are fine for funk, ballads, or pop comping. They don’t have the depth or bite of premium EPs, but they’re fun to play and sit well in a mix.
Organs – The pipe organ is full and straight, suitable for hymns or classical pieces. The jazz organ has a rotary-style sound baked in, though there’s no way to adjust speed or drawbars. It’s fixed, but usable.
Strings – Lush and slow-attack. Works well in layer mode with the piano. Don’t expect orchestral depth, but it’s decent for pads and emotional playing.
Harpsichord – Crisp and clear. No dynamics (as it should be). Good for Baroque practice.
Vibraphone – A gentle, mallet-style voice. Limited dynamic range but a nice option for jazz textures.
You can combine voices using Dual Mode (layering), but not Split Mode. There’s no ability to assign different voices to left and right hands. You also can’t edit voices—no ADSR, filter, or modulation options.
Overall, voice selection is narrow, but Yamaha picked the essentials. It’s a practical lineup for someone focused on piano, with just enough extras to explore and play around with.
Reverb & Effects
Both pianos offer four types of reverb:
- Room – Small room ambiance
- Hall 1 – Medium concert hall
- Hall 2 – Larger hall space
- Stage – Adds a sense of live stage presence
You can adjust the depth of the reverb, which helps tailor the sound to your environment. There are no chorus, delay, EQ, or other effects. What you hear is what you get.
To be honest, these reverbs are basic. They do add dimension, especially with headphones, but they’re not immersive or studio-grade. Still, they help prevent the sound from feeling dry or flat.
Speaker & Cabinet Influence
This is where things get more physical.
Even though the YDP-105 and P-145 have the same power rating—6W x 2—how they project sound is very different.
The YDP-105’s cabinet design gives it a natural acoustic boost. The speakers are mounted inside a wooden structure, and the extra space allows sound to resonate more naturally. This gives the piano voices more presence and warmth. Bass notes feel fuller. There’s more of a sense of space around the tone. It sounds more “real” in a room, especially at moderate volume.
The P-145, being a slimline portable, can’t compete in this regard. Its speakers are mounted in a tight plastic chassis, and while Yamaha has done a good job tuning them, the result is a slightly more compressed, directional sound. It’s clear, clean, and usable—but it doesn’t fill a room the way the YDP-105 can. At higher volumes, it can sound a little thin or boxy.
That said, with headphones, the differences disappear. Both pianos output stereo sound that’s clean and well-panned. If you’re practicing privately or recording via USB MIDI and using virtual instruments, this becomes irrelevant.
Real-World Playing Impressions
In actual use, the main piano voice on both models is surprisingly good for the price. It’s lively enough to feel musical, and it reacts to dynamics in a satisfying way. Is it perfect? No. There’s a lack of resonance, and it doesn’t sing the way high-end models do. But for practice, hobby playing, or early performance? It holds up.
The YDP-105 is more immersive out of the box due to its cabinet and speaker resonance. If you want a “piano in a room” experience, it’s the better of the two. The P-145 is more compact and sounds good enough, but you’ll appreciate it more with headphones or an external speaker.
Final Thoughts on Sound & Voices
You won’t get breathtaking realism from either of these pianos—but you will get a reliable, well-balanced sound that works across styles and situations. For their class, they punch above their weight.
- YDP-105 wins if you want warmth, fullness, and a better speaker projection.
- P-145 wins for headphone use, portability, and slightly tighter clarity.
If you’re serious about sound and plan to play a lot, adding a pair of quality headphones or connecting to studio monitors can dramatically improve your experience—especially with the P-145.
Bottom line: same engine, different delivery. Both are capable. The YDP-105 makes the most of it with its body, but the P-145 holds its own with a cleaner, leaner presentation.
Speaker System
When it comes to digital pianos, sound quality isn’t just about the samples and voices—it’s about how the sound reaches your ears. This is where the speaker system comes into play. It’s the difference between a piano that sounds flat and thin, and one that fills your room with rich, dynamic sound. Both the Yamaha YDP-105 and P-145 have identical speaker power ratings on paper—two 6-watt amplifiers powering two speakers—but that’s only part of the story.
In reality, the speaker system is where these two pianos start to diverge in a meaningful way. Yamaha made different design choices for each, based on their intended use cases. Let’s break it down in detail.
Power Specs: Identical Numbers, Different Realities
Both the YDP-105 and P-145 come with 6W x 2 stereo amplifiers, pushing sound through two built-in speakers. At first glance, that suggests these pianos will sound roughly the same in terms of loudness and projection. But it’s not just about wattage—it’s about cabinet design, speaker placement, materials, and resonance.
This is why, even though the P-145 and YDP-105 share the same power output, they sound and behave very differently in a real room.
Yamaha YDP-105: Bigger Body, Bigger Sound
Let’s start with the YDP-105. As part of the Arius series, this piano comes in a furniture-style cabinet. The wooden body isn’t just for aesthetics—it acts as a natural sound amplifier. The enclosure gives the speakers more room to breathe, and that space contributes to a rounder, fuller tone when compared to compact digital pianos.
The speaker grilles are positioned beneath the keyboard area, directing sound both outward and downward. The result is a more diffuse soundstage—one that fills a small room with less effort. It doesn’t feel like sound is just coming from the front panel—it has a presence in the air. You get more perceived bass, a smoother midrange, and a less “boxy” tone overall.
One of the best things about the YDP-105’s speaker system is that it helps disguise some of the limitations of the sound engine. The AWM samples aren’t ultra-detailed, but the resonance from the cabinet makes them feel a little more alive. The piano sound blooms slightly, especially in the lower octaves. It’s still not as rich as higher-end instruments, but it’s more satisfying than you’d expect at this price.
You can comfortably use the YDP-105 for home practice, casual performances, or lessons without feeling like you need external speakers. Even at low volumes, the tone has depth. At medium volume, it fills a bedroom or small studio nicely. Crank it up too high and yes, it can distort a bit—but you won’t need to push it that far.
Yamaha P-145: Clean, Focused, but More Limited
The P-145, by contrast, is a portable slab-style piano. Its body is slim and plastic, with far less internal volume than the YDP-105’s cabinet. Yamaha had to redesign the internal speaker configuration to work within that tight space, and while they did a respectable job, there are clear limitations.
The speakers are mounted under the chassis, angled slightly downward. Because the body is shallower and lighter, there’s less room for resonance. This leads to a sound that is tighter, more directional, and less immersive.
At low volumes, the P-145 sounds fine—very clean and clear, especially for solo practice. But as you increase the volume, the lack of a resonant chamber starts to show. Bass notes don’t rumble the way they do on the YDP-105. The sound projects more like a monitor speaker: forward and focused, but narrow.
This isn’t necessarily a bad thing—it depends on what you’re doing. If you’re playing in a small apartment, or practicing late at night, the P-145’s compact sound can be an advantage. It’s less likely to bother neighbors, and it still sounds detailed and articulate at low levels.
Where the P-145 struggles a bit is in emotional playing or expressive pieces. Without the extra acoustic lift of a cabinet, the sound feels more “trapped” inside the plastic housing. It can come off as flat in the midrange, and the low end never really thumps. You can tell the speaker cones are working, but they don’t have the body behind them to really push the air.
Room Impact: Size and Shape Matter
Because the YDP-105 has a more diffuse projection and larger cabinet, it interacts with the room in a more natural way. It sounds different depending on where you’re standing, and this adds a subtle realism that helps mimic the feel of a real piano. Sitting at the bench, you’ll hear sound coming from beneath you and radiating out, just like an upright acoustic.
The P-145 is more focused and linear. The sound comes directly toward the player, which can make it feel clinical—but also predictable. You always know what you’re getting, and it doesn’t change much based on room acoustics. That’s useful for recording, monitoring, or situations where you need control.
That said, if you place the P-145 on a soft surface or a heavy table, some of the sound can get muffled. Unlike the YDP-105, it doesn’t have the benefit of a built-in structure to optimize speaker direction, so it’s more sensitive to placement.
Headphone Use: A Level Playing Field
One area where both pianos are evenly matched is headphone output. Once you plug in a good pair of headphones, the differences in speaker systems disappear. Both units output clean stereo sound with the same AWM samples, and both allow for reverb effects and basic adjustments.
For late-night practice or private study, the headphone experience is solid on both models. There’s no noticeable hiss, and the stereo imaging is accurate. You also won’t hear the mechanical noise from the keys as much, especially on the P-145 with its quieter GHS Compact action.
Can You Improve the Sound?
Yes—if you’re not satisfied with the internal speakers on either model, you can use external amplification. Both the YDP-105 and P-145 lack dedicated line outputs, but you can route the signal through the headphone jack into powered monitors or a PA system using a stereo Y-cable.
This is more common with the P-145, especially for gigging or home studio use. External speakers help bring out the detail in the samples and add the low-end depth that’s missing from the built-in speakers. With the YDP-105, external amplification is less critical—its internal sound is already good for home playing—but you still have the option.
Final Thoughts on Speaker Systems
Here’s the bottom line:
- The YDP-105 wins when it comes to natural sound projection and immersive tone. Its larger cabinet acts like a passive amplifier, enriching the piano voices and making them more enjoyable in a room setting. It’s the better choice if you want the piano to feel full and acoustic-like right out of the box.
- The P-145 sounds clean and accurate, but it’s limited by its small chassis. It’s a solid performer for personal practice and headphone use, but you may want to invest in external speakers if you’re craving a more resonant, room-filling sound.
If you’re playing mostly at home and want something that sounds satisfying without extra gear, the YDP-105’s speaker system offers more bang for your buck. If portability and flexibility are more important, and you don’t mind adding speakers later, the P-145 holds its own—but won’t blow you away on its own.
Features & Functions
When it comes to beginner and intermediate digital pianos, most people aren’t looking for hundreds of features—they’re looking for the right features. The ones that matter. The ones that make playing easier, practicing more productive, and day-to-day use a little more enjoyable. Both the Yamaha YDP-105 and P-145 lean toward simplicity, but they don’t cut corners completely. In fact, what you get—and what you don’t—is a big part of the buying decision.
Let’s dig deep into what each model offers in terms of functions, modes, controls, and usability, and examine how those choices impact different types of players.
Core Philosophy: Keep It Simple
First off, both the YDP-105 and P-145 are deliberately minimalist. These are not arranger keyboards or full-featured workstations. They’re focused digital pianos with 88 weighted keys, a handful of instrument sounds, and a few utility features designed to support a traditional playing experience.
Neither model includes flashy extras like accompaniment rhythms, auto-chord features, built-in multi-track recorders, or LCD displays. That might sound like a downside, but for many players—especially beginners—it’s actually a plus. There’s less menu diving, fewer distractions, and more focus on playing.
That said, Yamaha has made some notable distinctions between the two models that reflect different priorities.
Modes of Play: Solo, Layered, and Duo
Both models include three primary playing modes:
- Normal Mode – Standard single-voice piano playing.
- Dual Mode (Layering) – This lets you play two voices simultaneously across the entire keyboard. Common combinations are piano + strings or electric piano + vibraphone. There’s no ability to balance the volume between layers, though—both voices are locked at the same level. You also can’t edit split points or assign voices to different key ranges.
- Duo Mode – This splits the keyboard into two identical pitch zones, one for each half. It’s perfect for teacher-student scenarios where both players can play the same notes in the same octave range side-by-side. Both the YDP-105 and P-145 support this mode, and it’s one of the more underrated features for learning environments.
What you don’t get is Split Mode (assigning different voices to the left and right hands separately). This feature is usually reserved for higher-end models and arranger keyboards.
Metronome and Tuning
Both models include a built-in metronome, which is easy to access and customizable in terms of tempo and time signature. It’s an essential practice tool and works exactly as expected—no frills, just function.
You also get transpose and fine tuning capabilities:
- Transpose lets you shift the pitch of the entire keyboard up or down in semitone steps. Useful for playing in difficult keys, or accompanying vocalists.
- Tuning allows you to adjust the pitch in small increments (cents) to match another instrument or recording.
These tools are especially useful for students, performers, and anyone who wants to experiment without physically relearning pieces in different keys.
Reverb and Sound Shaping
Both pianos offer four types of reverb, and that’s pretty much the extent of onboard sound processing. The reverb types are:
- Room – Adds a small amount of natural room ambiance.
- Hall 1 – Simulates a medium-sized concert hall.
- Hall 2 – Simulates a large performance hall.
- Stage – Mimics the sound of playing on a stage, with tighter reflections and space.
You can adjust the depth of the reverb, but that’s about it. There are no EQ controls, no chorus, no rotary effects, and no ability to tweak voices in terms of tone, brightness, or attack. Again, this simplicity is by design—but more advanced users might feel the limitations quickly.
For beginner and intermediate players, the reverb is enough to add realism without overwhelming the experience.
Controls and Interface
The user interface on both models is bare-bones.
- YDP-105 has a few buttons (power, function, volume) and relies on key/button combinations for changing voices and settings. There’s no screen, and no indicators to tell you which voice is currently active—you’ll need to memorize or reference the manual.
- P-145 also uses a minimalist interface: volume knob, power button, and a few labeled voice buttons. To access additional features (metronome, transpose, reverb), you’ll use key + button combinations. Again, no display, no menus, and no visual feedback.
While this design keeps things simple and clean, it can feel a bit outdated. You’ll likely find yourself keeping the user manual nearby during the first few weeks.
This is where the P-145 pulls ahead, thanks to a feature the YDP-105 lacks entirely…
Smart Pianist App Compatibility (P-145 Only)
Here’s a major difference between the two: the P-145 is compatible with Yamaha’s Smart Pianist app, while the YDP-105 is not.
This app transforms your phone or tablet into a touchscreen control center for the piano. You can:
- Select and preview voices
- Adjust reverb levels
- Control the metronome visually
- Split and layer voices
- Save settings as presets
It also includes interactive sheet music, chord detection for songs in your library, and a simple recording function.
This app changes the game for beginners. Instead of memorizing cryptic button/key combinations, you get a clean, modern interface with labels and graphics. For anyone used to touchscreen tech (so, basically everyone), Smart Pianist makes the P-145 feel like a much more advanced instrument.
And because the app connects via USB to Host, it’s not Bluetooth dependent—so latency and stability are excellent.
The YDP-105 doesn’t support Smart Pianist, nor does it have any kind of app-based control. It’s a closed system, for better or worse. Some might appreciate the old-school consistency, but in 2025, the lack of app integration is starting to feel like a drawback.
Recording and Playback
Neither the P-145 nor YDP-105 has internal recording capabilities. There’s no onboard memory, no MIDI recorder, no audio recorder. If you want to record your playing, you’ll need to connect the piano to a DAW or recording device using the USB-MIDI port and record externally.
This is one of the most noticeable omissions at this price point. Many beginner and intermediate players benefit from being able to record and listen back to their playing. It’s a great learning tool, and its absence is a real limitation—especially on the YDP-105, which is marketed as a home/study instrument.
The workaround is external recording through a computer, tablet, or smartphone. Yamaha’s Smart Pianist app does offer basic recording (MIDI only) when connected to the P-145, which gives that model a clear edge once again.
Pedal Support
The YDP-105 includes a built-in three-pedal unit: sustain, soft, and sostenuto. These pedals are mounted into the cabinet and mimic the feel of acoustic piano pedals reasonably well. The sustain pedal supports half-pedaling, adding expressive control for players who want to practice classical repertoire.
The P-145, by default, comes with the FC5 footswitch—a basic sustain pedal with on/off functionality. It works, but it’s not ideal. If you want half-pedaling or more realistic feedback, you’ll need to upgrade to the FC3A (continuous pedal) or the full LP-5A three-pedal unit (which requires the L-100 stand).
Again, the P-145 offers flexibility, but it costs more to build a full setup. The YDP-105 is all-inclusive, which is great for someone who doesn’t want to think about accessories.
Connectivity and MIDI Control
Both pianos include a USB to Host port (MIDI only), allowing you to connect to a DAW, music app, or recording software. They both lack Bluetooth MIDI or Bluetooth audio, which is a bummer considering many modern devices are moving away from wired ports.
There are also headphone jacks on both models (dual ¼” jacks on the YDP-105, single on the P-145). This is useful for quiet practice and duet situations.
Neither model includes line outs or audio ins. If you want to amplify the sound, you’ll need to use the headphone jack as a line output.
Final Thoughts on Features & Functions
If you’re someone who values simplicity and a “just play” philosophy, both the YDP-105 and P-145 offer a clean, distraction-free setup. You won’t spend hours navigating menus or configuring sounds—you’ll just sit down and play.
But if you’re someone who wants modern convenience and app integration, the P-145 wins hands down. Smart Pianist adds a level of interactivity and customization that makes the instrument feel more alive and more aligned with how people use tech today.
Meanwhile, the YDP-105 delivers a more complete out-of-the-box package. You get three pedals, a cabinet, and a full suite of practical features—just no frills, no upgrades, and no app support.
In summary:
- The YDP-105 is a complete, no-nonsense home piano with essential features and traditional design.
- The P-145 is more modular, more tech-friendly, and a better fit for digital natives—so long as you’re okay piecing together the extras.
Both are functional. One is conventional. The other is quietly innovative. Your choice depends on how you want to interact with your instrument.
Connectivity
Connectivity might not be the flashiest spec when comparing digital pianos, but it’s one of the most important—especially in a world where musicians, students, and hobbyists expect their instruments to work seamlessly with computers, mobile devices, DAWs, learning apps, and amplifiers. A digital piano’s connectivity determines not just how versatile it is today, but how future-proof it will be as your musical needs grow.
When comparing the Yamaha YDP-105 and the Yamaha P-145, connectivity reveals a few key differences. On the surface, both seem similarly equipped—basic, functional, minimal. But once you dig a little deeper, it’s clear that Yamaha made distinct choices in how each piano connects to the digital world. One sticks to tradition; the other leans slightly toward modern integration.
Let’s unpack each connectivity option available on these two models and evaluate how well they serve different user types—from casual home players to students, teachers, and aspiring producers.
USB to Host (MIDI Connectivity)
Both the YDP-105 and P-145 feature a USB to Host port. This is the primary digital connection on both models, and it allows for MIDI communication between the piano and a computer, smartphone, or tablet.
Let’s be clear—this is MIDI only. It doesn’t send audio. That means you can use the keyboard to control virtual instruments or record MIDI data in a DAW (like Logic Pro, Ableton, or FL Studio), but you can’t stream the piano’s internal sound digitally into your computer.
To use this port effectively, you’ll need a USB Type B to USB Type A cable (or USB B to USB C, depending on your device). Once connected, both pianos will be recognized as class-compliant MIDI devices, which means no drivers are required for most modern operating systems—plug and play.
This opens up a lot of doors:
- Recording MIDI performances into a DAW
- Playing software instruments on your computer
- Using online learning platforms like Flowkey, Simply Piano, or Skoove
- Controlling synth plugins or notation software
This connection is particularly important for students and home-recording musicians who want to practice or produce music with modern tools. It allows your digital piano to become more than a standalone instrument—it becomes part of your digital music environment.
No USB Audio: A Limitation Worth Noting
It’s worth emphasizing again that neither the YDP-105 nor the P-145 supports USB audio. That means you can’t directly record the piano’s internal sounds into your DAW without using the headphone jack as an analog output. If you’re recording and want to preserve the exact sound you hear through the speakers, you’ll need an external audio interface or a workaround involving analog cables.
Higher-end Yamaha models—like the P-225 or Clavinova series—include USB audio, which allows for direct digital audio recording via USB, but you won’t find that here. This is one area where both models feel a bit outdated.
Headphone Jacks
YDP-105:
This model includes two standard 1/4-inch headphone jacks, located beneath the keyboard. This is ideal for:
- Silent practice (no speaker output when headphones are plugged in)
- Duets or teacher-student practice with two headphone sets
- Output to external speakers or amplifiers using a Y-cable (TRS to dual TS)
Having two jacks is a nice touch, and it fits with the YDP-105’s role as a home teaching or practice instrument. It’s an old-school feature that continues to offer real-world convenience.
P-145:
The P-145 has one 1/4-inch headphone output, also located underneath the keyboard. It works the same way—plug in headphones, and the speakers are automatically muted. You can use it for silent practice or as an analog line out.
The single jack may feel limiting in teaching scenarios or when playing duets, but it’s not a dealbreaker. You can always use a headphone splitter if needed.
Using the Headphone Jack as an Audio Output
Since neither piano includes dedicated line out jacks, the headphone jack becomes your main analog output if you want to connect to:
- Powered monitors
- External speaker systems
- Audio interfaces for recording
- Mixers or PA systems for live sound
Just be aware: headphone outputs are not the same as line-level outputs. They’re amplified and can introduce noise or distortion if pushed too hard or improperly matched with external gear. If you’re connecting to an external system, use a TRS to dual 1/4-inch TS cable or a TRS to stereo RCA, and keep the volume around 60–70% to avoid overloading the input.
The YDP-105, again, has the advantage of dual headphone outputs, which makes it slightly more flexible in real-world setups.
Pedal Connectivity
Pedal support is also part of the connectivity equation.
YDP-105:
The YDP-105 includes a built-in three-pedal system, hardwired into the cabinet. You get:
- Sustain
- Soft
- Sostenuto
These are functional and reasonably realistic, and the sustain pedal supports half-pedaling, which allows for more nuanced control—great for classical and expressive pieces.
Because the pedal unit is built in, you don’t have to worry about extra cables, compatibility, or setup—it’s plug-and-play from day one.
P-145:
The P-145 comes standard with a single FC5 footswitch, which plugs into the rear panel. It offers basic on/off sustain. That’s it. It does not support half-pedaling, and the tactile feel is nowhere near as convincing as the YDP-105’s pedal unit.
However, the P-145 does offer optional upgrades:
- The FC3A pedal adds half-pedaling support and a more realistic feel.
- The LP-5A three-pedal unit (used with the L-100 stand) mimics the full YDP setup, including sostenuto and soft pedals.
This flexibility is good—but it comes at an extra cost and requires a compatible stand. If you want the full piano experience from the P-145, you’ll need to build it piece by piece.
App Connectivity: A Key Differentiator
Here’s where the P-145 clearly pulls ahead: Smart Pianist app compatibility.
With a USB to Host cable and a connected device (iPhone, iPad, or Android tablet), you can access Yamaha’s Smart Pianist app. This transforms your tablet or phone into a touchscreen control center for the piano.
Through the app, you can:
- Select voices with labels and previews
- Adjust metronome tempo and time signature
- Tweak reverb settings
- Access built-in music scores
- Record and play back MIDI performances
- Use chord tracking for songs in your library
This greatly improves usability—especially for beginners who don’t want to memorize button/key combinations to switch sounds or change settings.
Unfortunately, the YDP-105 does not support Smart Pianist. It’s a closed system with no app integration. All functions must be accessed using key/button combinations and reference charts from the manual. This is fine for purists who don’t want or need extra tech, but it feels dated in comparison.
Bluetooth? Not Here
Neither model includes Bluetooth audio or Bluetooth MIDI, which is disappointing in 2025. Many competing brands now offer at least Bluetooth MIDI, if not full audio streaming.
This means you can’t:
- Stream backing tracks or YouTube tutorials wirelessly through the piano’s speakers
- Connect to MIDI learning apps without a cable
- Use the piano as a Bluetooth speaker
If wireless functionality is important to you, you’ll either need a higher-end Yamaha model or a competitor like Roland or Casio that offers built-in Bluetooth. You can also use external Bluetooth MIDI adapters or audio receivers, but it adds cost and complexity.

Final Thoughts on Connectivity
In terms of pure I/O, both the YDP-105 and P-145 are fairly basic. You get USB MIDI, headphone out, and pedal inputs—and not much else. For traditional players, that’s enough. But for tech-savvy musicians, producers, and students using modern workflows, that minimalism can feel restrictive.
The YDP-105 is straightforward. It assumes you’ll be using it mostly in a fixed home environment. It gives you everything you need for private practice and in-person lessons, and nothing you don’t.
The P-145, while also minimal, sneaks in just enough modern functionality to make it feel more current. Smart Pianist support alone adds a ton of value, and optional pedal upgrades allow it to scale with your needs.
In the end, if you’re someone who just wants a plug-in-and-play experience, the YDP-105 keeps things clean and focused. If you want more flexibility, control via mobile apps, and the option to grow your setup over time, the P-145 is clearly the more connected choice.
Value for Money
When you’re shopping for a digital piano—especially one under $1,000—you’re not just comparing specs. You’re trying to answer a much bigger question: what do I actually get for the money? That’s where the idea of value really kicks in. And when comparing the Yamaha YDP-105 and P-145, the value each offers is tightly linked to their use cases, design priorities, and upgrade paths.
At first glance, it might seem like the YDP-105 costs significantly more, while the P-145 feels like a steal. But that’s only part of the picture. Once you factor in accessories, long-term goals, and how much you care about portability or app connectivity, the value equation becomes more nuanced.
Let’s break it down.
Base Price vs. Total Cost
The Yamaha P-145 typically retails for around $499–$599 USD, depending on the region and retailer. That includes the piano itself and a basic sustain footswitch (the FC5). At that price, it’s one of the most affordable 88-key fully weighted digital pianos on the market.
The Yamaha YDP-105 usually comes in at around $899–$999 USD. That includes the full furniture-style cabinet, three-pedal system, and bench in most bundles. You’ll see occasional sales or seasonal discounts, but it stays within that range.
So on paper, the P-145 is $400–$500 cheaper. But here’s the catch: the P-145 is only the keyboard. If you want a full setup with a proper stand and pedals—one that mirrors the YDP-105—you’ll need to add:
- Yamaha L-100 stand (~$120)
- LP-5A three-pedal unit (~$100)
- Optional bench (~$50–$100)
Total: Add roughly $220–$300 to the P-145 to get it on equal footing in terms of form and function.
So if you plan on using the P-145 as a stationary home piano and want the full experience, your final price can land around $750–$900, which puts it closer to the YDP-105 than you might expect.
What the YDP-105 Delivers
For that $899–$999 price tag, you get a complete, integrated solution. You don’t have to think about accessories, compatibility, or piecing together your setup. Everything is there: a full cabinet, a realistic three-pedal unit, a wide music rest, and a stable, upright-style build.
You also get better speaker resonance thanks to the larger body, and a piano that looks and feels at home in a living room, studio, or lesson space. It’s simple, reliable, and offers exactly what a beginner or casual player needs without feeling like a budget compromise.
And even though it lacks app support or advanced features, it nails the essentials. For many, especially traditional players or parents buying for their kids, that’s real value—a quality instrument that doesn’t require add-ons or upgrades right out of the gate.
Where the P-145 Shines
The P-145’s value comes from its modularity and modern sensibility. At its base price, it offers a great key action (arguably better than the YDP-105’s), the same AWM sound engine, and compatibility with Yamaha’s Smart Pianist app, which gives it a huge usability advantage for beginners or tech-savvy users.
If you don’t need the full stand and pedals—or if you already have them—the P-145 becomes an unbeatable value. For someone who just needs a solid 88-key weighted piano for MIDI input, home recording, gigging, or casual practice, the P-145 offers a ton of functionality in a light, affordable package.
It’s also a better option for those with limited space, those who want to move the instrument frequently, or those planning to upgrade later. You’re not locked into a fixed form factor, and you’re not paying for features you might not use.
Which Offers More Value?
That depends on who you are:
- For a student or beginner with no setup who wants a plug-and-play home piano with everything included, the YDP-105 is the better value. You get a full-featured, stable piano with zero guesswork and no extra costs.
- For someone on a tighter budget, or a player who wants flexibility and portability, the P-145 delivers more bang for the buck. You get a better action, lighter footprint, and app support—all for significantly less money up front.
- If you’re looking for long-term value and a “buy once, use for years” type of piano, the YDP-105 has fewer upgrade paths but more immediate completeness. The P-145 has more options, but they come with more decisions and accessories.
Final Verdict
Both pianos offer great value—but in different ways.
- YDP-105 = better for set-it-and-forget-it buyers who want something stable, elegant, and complete. You pay more up front, but get everything you need.
- P-145 = better for flexible users, budget-conscious buyers, and those who prefer to start small and expand over time. It’s more portable, more app-connected, and cheaper to get started with.
In other words: neither is overpriced. They just offer two flavors of value. The real question is how you define it based on your priorities.
Conclusion
After comparing the Yamaha YDP-105 and P-145 across every major category—design, feel, sound, features, speakers, connectivity, and value—it’s clear that these two pianos serve different needs. They share the same brand quality and sound engine, but the way they deliver the experience couldn’t be more different.
The YDP-105 is built for permanence. It looks and feels like a real home piano. With its full cabinet, built-in three-pedal unit, and better speaker projection, it’s ideal for players who want a traditional playing experience without the complexity or expense of higher-end models. It’s a fantastic option for beginners, students, or families who want a reliable, stylish piano that blends into a living space and just works.
On the other hand, the P-145 is built for movement, flexibility, and modern convenience. It’s smaller, lighter, and easier to integrate into a variety of environments—from tight apartments to small studios to live setups. The newer GHS Compact action feels better than the older standard GHS in the YDP-105, and Smart Pianist app support gives it a modern edge in terms of control and usability. It’s perfect for digital-native players, mobile musicians, or anyone who wants a quality piano without committing to a full console-style instrument.
If you want a piano that stays in place and feels like a real piece of furniture, get the YDP-105. If you want a piano that goes where you go and adapts to your setup, get the P-145.
There’s no wrong choice here—just the better fit for how, where, and why you play.
