Design and Build Quality

When comparing two digital pianos like the Casio PX-870 and the Roland F107, design and build quality are about more than just looks. The cabinet design, weight, sturdiness, layout of controls, pedal placement, and overall “living with it day to day” feel make a huge difference. After all, this isn’t just an instrument you’ll interact with when practicing—it’s also a piece of furniture that will sit in your room for years.

Both Casio and Roland approach design with slightly different philosophies, and those choices become obvious when you put the PX-870 and F107 side by side. One feels like a modern, traditional home piano that emphasizes practicality, while the other leans into a cleaner, minimalist look designed to fit contemporary living spaces. Let’s unpack what that means in practice.

Overall aesthetics and first impressions

At first glance, the Casio PX-870 looks very much like a digital piano. Its design is fairly classic: a slim upright console, straight lines, a matte finish, and a sliding key cover. It’s not trying to hide what it is, nor is it making bold statements. For many people, this is a good thing. It blends into a living room, music room, or even a bedroom without feeling flashy. It’s available in black, white, or walnut finishes, which gives some flexibility to match existing furniture.

The Roland F107, on the other hand, immediately comes across as more modern and minimal. Its design feels closer to a piece of Scandinavian-inspired furniture than a traditional console piano. The front panel is extremely clean, with only a few buttons and indicators, and Roland expects users to interact with its companion app for deeper settings. This creates a very streamlined look that some will love and others might find too dependent on smart devices. The F107 is available in black or white, both with a slightly satin sheen that looks refined and subtle.

When placed in a contemporary apartment or a modern living space, the Roland F107 fits in almost invisibly—it could pass as a sleek piece of furniture. The Casio PX-870, by contrast, leans toward the familiar upright piano aesthetic, which may appeal to those who want something that “looks like a piano” rather than an anonymous piece of decor.

Dimensions and footprint

Both pianos are designed to be slim and space-saving, a big reason why people choose these kinds of digital pianos over full-sized uprights or acoustic instruments.

The Casio PX-870 measures around 54.8 inches wide, 11.7 inches deep, and 31.5 inches tall. At about 75 pounds (34 kilograms), it’s relatively lightweight for a console-style instrument, making it easier to move than a traditional piano or even some higher-end digitals. Its depth—less than 12 inches—makes it particularly compact. You can push it against a wall without it jutting too far into the room.

The Roland F107 is just slightly smaller in width, at about 53.5 inches, but it’s deeper at 13.5 inches. It stands about 31 inches tall and weighs a touch more, around 79 pounds (36 kilograms). This means the F107 takes up a little more floor space, though not by much. It’s still slim and room-friendly, but the Casio wins out in terms of the absolute narrowest footprint.

If your space is very tight, the PX-870 has the advantage of being slimmer. But for most people, both instruments are compact enough that they won’t feel imposing in a living room or bedroom.

Build quality and materials

Both instruments are primarily constructed from MDF/particle board with a textured veneer finish. This is standard for digital pianos in this price category. Don’t expect solid wood or luxury veneers—that’s reserved for higher-end models like Yamaha Clavinova or Roland LX series.

That said, the execution differs slightly. The Casio PX-870 feels sturdy once assembled, but some of the panels can feel lighter and less dense. It’s perfectly adequate, but if you press against the side panels you’ll notice a little flex. The Roland F107, in comparison, feels slightly more robust, with panels that seem to fit together more seamlessly. The overall impression is that the Roland is marginally better built, though both will last if treated with care.

Assembly for both is a similar process: you’ll receive a flat-pack cabinet, attach the base and side panels, and mount the keyboard unit onto it. It’s a job for two people, especially when lifting the main piano body into place. Once set up, both look like proper furniture pieces rather than just keyboards with stands.

Control layout and usability

This is an area where the two brands diverge strongly.

The Casio PX-870 uses a very straightforward control system. Buttons are placed to the left of the keyboard, and while you’ll still need to memorize a few key combinations to access secondary functions, the controls are tactile and accessible without needing a smartphone. For players who just want to sit down, turn it on, and adjust things quickly, Casio’s approach is intuitive. The sliding key cover also adds practicality, protecting the keys from dust without needing an external cloth or case.

Roland’s F107 takes a more minimalist approach. The control panel has very few physical buttons—just enough to power on, adjust volume, and access a couple of basic sounds. For anything beyond that, you’re expected to connect to Roland’s Piano Every Day app. While this keeps the physical instrument looking incredibly sleek, it can frustrate players who dislike relying on a phone or tablet to access core functions. Some players may love the clean aesthetic; others may feel it’s a bit of a compromise.

Pedal units

Both the Casio PX-870 and Roland F107 come with built-in triple pedal units, which is a major advantage over lower-end portable models that often rely on single or optional pedals. Each offers damper (with half-pedal capability), sostenuto, and soft pedals, closely mimicking a real piano.

Casio’s pedal action is light and does the job but feels a little less resistant than an acoustic piano. Roland’s pedal unit, though also made of plastic with a metal surface, has slightly more realistic resistance, which may appeal to players working on pedal control and nuance. Neither is perfect compared to a grand piano pedal system, but Roland’s has the edge in feel.

Practical considerations

Noise and vibration are worth mentioning when talking about design. Both pianos are relatively quiet in mechanical action compared to cheaper keyboards, but the Casio PX-870’s key action can feel slightly noisier when played hard. In a quiet apartment at night, this might be noticeable. The Roland’s PHA-4 action feels more dampened mechanically, producing a softer “thunk” that is less intrusive.

Both have headphone jacks, but Casio includes two, while Roland only has one. If you’re in a teaching situation or want to play duets quietly, that’s a point for Casio.

From a furniture perspective, the Roland has a slightly more modern profile with rounded corners and a less “boxy” shape. Casio looks a little more utilitarian, though the walnut finish option gives it a warmer, more homely feel than Roland’s minimalist black or white.

Long-term durability

Neither instrument is designed to last decades like an acoustic piano, but both should serve well for many years with reasonable care. The biggest wear factors are usually key action and pedal durability. Casio’s action has been known to develop a bit of looseness after years of heavy use, while Roland’s PHA-4 generally holds up better. Pedals on both models are replaceable, though because they are integrated into the cabinet, it’s not as simple as swapping a plug-in pedal.

In terms of resale value, Roland instruments tend to hold their price slightly better, largely because the brand has a stronger reputation among serious pianists. Casio’s Privia series is respected, but Roland carries more weight in the digital piano world.

Summary of design and build quality

• The Casio PX-870 is slimmer, slightly lighter, and more traditional in appearance. It offers practical touches like a sliding key cover and dual headphone jacks. It looks like a piano and feels approachable.
• The Roland F107 is more modern and refined, with a minimalist design that integrates seamlessly into contemporary spaces. It feels a touch more solidly built and has a pedal unit with slightly better resistance. The trade-off is that it relies heavily on app-based control.

In the end, design preference will depend on your priorities. If you want something that screams “I’m a piano” and gives you straightforward controls, the PX-870 is the better match. If you value a minimalist, contemporary look and don’t mind using an app for control, the F107 feels more refined.

Keyboard Action

If there’s one factor that can make or break a digital piano, it’s the keyboard action. You can forgive average speakers if you practice with headphones, and you can work around limited sound libraries if you mostly play acoustic piano voices. But if the keys don’t feel right under your fingers, the experience is always going to fall short. That’s why the comparison between the Casio PX-870 and Roland F107 really comes alive when we zoom in on the keyboard action. Both instruments aim to replicate the feel of an acoustic piano, but they go about it in slightly different ways, each with their own strengths and compromises.

Let’s break it down in detail.

Casio PX-870: Tri-Sensor Scaled Hammer Action II

Casio equips the PX-870 with its Tri-Sensor Scaled Hammer Action II, which has been the workhorse action for the Privia series for several years now. While it’s not brand-new technology, it’s mature and refined, and Casio has a reputation for squeezing a lot of quality out of its midrange instruments.

The “scaled” part means that the keys are weighted to be heavier in the lower register and lighter in the higher register, just like on an acoustic piano. This gives a more natural progression across the keyboard, making left-hand bass notes feel grounded and right-hand treble passages lighter and more agile. The action uses actual hammers (though not wooden ones, as in higher-end models), giving it an authentic sense of weight rather than relying on springs.

The “tri-sensor” element is important. Each key has three sensors, which allows the piano to register repeated notes more accurately without the key needing to return fully to its top position. On a real acoustic piano, if you press a key halfway up after striking it, you can repeat the note quickly. Many cheaper digital pianos without triple sensors struggle with this, cutting off repeated passages or feeling sluggish. The PX-870 avoids that problem.

Casio also pays attention to surface feel. The PX-870 has simulated ivory and ebony keytops with a slightly textured matte finish. This isn’t just for looks—the texture helps absorb moisture, meaning your fingers don’t slip as easily during long practice sessions. For beginners, it adds comfort, and for advanced players, it provides more grip and control.

The overall feel of the action is on the lighter side compared to some other brands. This can be an advantage if you’re playing for extended periods, as your hands won’t fatigue as quickly. However, players who are used to upright or grand pianos may find it feels a little less substantial, with a hint of “plastic” in the rebound.

Roland F107: PHA-4 Standard

Roland has a reputation for producing some of the best digital piano actions outside of actual acoustic grands, and the PHA-4 Standard action found in the F107 is no exception. It’s used in several of Roland’s midrange instruments, including the FP-30X and F701, and has won praise for being one of the most realistic in its class.

Like Casio’s action, it’s graded—heavier in the bass, lighter in the treble. But the weighting feels a bit deeper and heavier overall, which is closer to an upright acoustic feel. This added resistance makes the keys feel more substantial under the fingers, which many experienced pianists appreciate.

The PHA-4 also uses triple-sensor detection, so repeated notes register cleanly without delay. Where Roland distinguishes itself is in the escapement simulation. On an acoustic grand piano, when you press a key slowly, you feel a slight “notch” about halfway down, where the hammer mechanism releases. This tactile detail has no functional purpose in a digital piano, but it adds realism for players used to grand actions. Roland includes this in the PHA-4, giving the keys an extra layer of authenticity.

Surface feel is also excellent. The PHA-4 uses simulated ivory and ebony textures similar to Casio’s, but they feel slightly more refined, with a soft grip that mimics the porous nature of real ivory.

One of the key differences is mechanical noise. The PHA-4 is relatively quiet when played, producing a muted thud that’s less noticeable in apartment situations. Casio’s action is fine but tends to produce slightly more audible noise when struck hard. This may not matter much in normal practice, but if you live in thin-walled apartments and play late at night with headphones, it could make Roland’s action feel less intrusive.

Comparing weight and responsiveness

When you place your hands on the PX-870 and F107 back to back, the first thing you’ll notice is the difference in weight. The Casio feels lighter, faster, and easier on the fingers. It’s forgiving for beginners and players who aren’t looking for heavy resistance. The Roland feels firmer, with a deeper throw and more resistance, encouraging a technique closer to what you’d use on an acoustic piano.

Responsiveness in both actions is excellent, thanks to triple sensors, but Roland has a slight advantage in how it handles soft dynamics. The PHA-4 lets you play whisper-quiet pianissimo passages with better control, while Casio sometimes struggles to capture the very softest touches as distinctly. On the flip side, Casio’s lighter action can feel quicker for trills and fast passages, though Roland’s realism still appeals more to pianists working on nuanced technique.

Long-term playability

Another factor to consider is how the actions hold up over time. The Casio action has been reported by some long-term users to develop a bit of looseness after years of heavy use. It doesn’t fail, but the keys can feel slightly rattly compared to when new. Roland’s PHA-4 action, on the other hand, is generally considered more durable and holds its resistance better over time. This may not matter for casual players, but for daily practice over several years, Roland likely ages more gracefully.

Suitability for different players

If you’re a beginner or intermediate player, the Casio PX-870 action is more than sufficient. It gives you the graded feel, textured surfaces, and fast repetition you need to develop proper technique. The lighter touch may even be an advantage, reducing hand fatigue while you’re still building strength.

If you’re an advanced pianist or someone who already plays acoustic uprights or grands, the Roland F107’s PHA-4 action will probably feel more familiar. The heavier weight and escapement simulation make it more realistic, and it gives you more control over dynamics. It’s also the better option if you’re serious about building finger strength and preparing for acoustic performance.

Pedal interaction and action synergy

One often overlooked aspect of keyboard action is how it interacts with the pedals. Both the PX-870 and F107 include half-pedal support, which allows for more nuanced sustain control. On the Casio, the lighter action pairs with the slightly lighter pedal resistance, giving a cohesive but somewhat simplified playing experience. On the Roland, the heavier action pairs with firmer pedal resistance, again mimicking the acoustic upright feel more closely. This synergy adds to Roland’s realism, making pedal-heavy classical or romantic repertoire feel more authentic.

Small but important details

There are a few subtle differences that don’t show up in spec sheets but become obvious in playing. For instance, Roland’s keys feel like they sink slightly deeper into the keybed, giving the impression of a longer key pivot. This translates into better control when playing toward the back of the keys (for example, black keys or wide stretches). Casio’s shorter pivot can feel a little cramped in comparison, especially for advanced players.

Another detail is key return speed. Roland’s keys spring back with a natural pace that feels like an acoustic. Casio’s are slightly quicker, which some may like for fast runs but can feel less organic.

Final thoughts on keyboard action

Both the Casio PX-870 and Roland F107 offer excellent key actions for their price range. Casio’s Tri-Sensor Scaled Hammer Action II is light, fast, and beginner-friendly, while Roland’s PHA-4 Standard is weightier, more nuanced, and more realistic for serious pianists.

If I had to summarize:

• Choose the Casio PX-870 if you’re a beginner, value comfort, or want an action that won’t tire you out.
• Choose the Roland F107 if you’re more advanced, want to mimic an acoustic piano as closely as possible, or care about long-term durability.

In the end, this category is where Roland establishes its strongest lead. While Casio delivers great value and playability, Roland’s PHA-4 Standard action simply feels closer to the real thing.

Sound Engine

When it comes to digital pianos, the sound engine is every bit as critical as the keyboard action. After all, the point of these instruments is to replicate the experience of playing a real piano, and if the sound doesn’t convince you, the illusion falls apart. Both Casio and Roland have their own proprietary sound technologies, and they approach the problem of realism in different ways. The Casio PX-870 relies on its AiR (Acoustic and Intelligent Resonator) Sound Source, while the Roland F107 makes use of the SuperNATURAL Piano engine. Both are capable systems, but they offer different flavors of tone, levels of expressiveness, and flexibility. Let’s dig into what those differences actually mean for someone sitting down to play.

Casio PX-870: AiR Sound Source

Casio’s AiR engine has been the backbone of their Privia series for years, and it’s become quite refined. It’s a sample-based system that uses recordings of real grand pianos as the foundation. These samples are paired with intelligent processing to add things like resonance and decay modeling, which makes the notes feel alive rather than static.

One of the big selling points is the use of lossless compression in storing the samples. Instead of cutting corners with heavily compressed audio, Casio keeps the original recordings intact, ensuring that what you hear is closer to the real piano sound. The result is a main piano tone that’s clear, bright, and crisp. It doesn’t have the same lushness as more advanced engines, but it holds its own remarkably well in this price range.

The PX-870 also simulates key details of acoustic pianos, such as:

• Damper resonance: When you press the sustain pedal, the strings in an acoustic piano resonate together, creating a rich wash of sound. The PX-870 reproduces this effect.
• String resonance: If you silently hold down a key and strike another, the sympathetic vibrations cause the held string to ring. Casio mimics this interaction digitally.
• Key-off simulation: When you release a key, you hear a subtle noise of the damper returning to the string. Again, Casio includes this nuance.

These small touches make the experience more convincing. They don’t just give you “notes” but rather the subtle imperfections and noises that come with a real piano.

Casio also equips the PX-870 with 256-note polyphony, which is excellent. Polyphony refers to how many notes can sound at once, including sustained tones and resonance effects. With 256, you’re unlikely to ever hit a ceiling, even when playing demanding classical repertoire with heavy pedal use.

Beyond the acoustic piano sounds, the PX-870 comes with a modest set of additional tones: a handful of electric pianos, organs, strings, harpsichord, and a few others. They’re serviceable, but clearly the focus is on the main piano voices. If you’re hoping for a huge palette of non-piano sounds, the PX-870 isn’t built for that.

Overall, the AiR engine is reliable and pleasing, though it leans toward a clean, bright sound that some players might describe as slightly “sterile.” It’s a sound that cuts through well and works great for classical practice, but it may lack a bit of warmth or organic depth compared to Roland’s approach.

Roland F107: SuperNATURAL Piano

Roland’s SuperNATURAL Piano engine takes a different tack. Instead of relying purely on samples, Roland combines sampling with behavioral modeling. What that means is that, yes, there are recordings of real pianos at the core, but the engine also uses mathematical models to simulate how a piano behaves under different conditions. This hybrid approach gives the sound more fluidity and responsiveness.

For example, on an acoustic piano, the way a note evolves depends on how hard you strike it, how long you hold it, what other notes are sounding, and how the damper interacts. Roland’s engine continuously calculates these interactions rather than just playing back a static recording. The result is a tone that feels more “alive” and less predictable.

A key strength of the SuperNATURAL engine is its handling of dynamics. You can go from the softest whisper of a pianissimo to a thunderous fortissimo, and the transitions feel smooth and natural. On some sample-based systems, you can hear the “steps” between velocity layers (for example, the tone suddenly shifting when you press a little harder). With SuperNATURAL, those transitions are seamless.

Roland also goes deep on resonance and mechanical modeling. The F107 recreates damper resonance, string resonance, cabinet resonance, and even the subtle noises of the hammers and keys. This layering of details adds to the immersive quality, making you forget that you’re listening to speakers.

One standout feature is unlimited polyphony for piano tones. This is not marketing fluff—it really means that you can use the damper pedal liberally, layer thick chords, and play dense classical passages without ever experiencing note dropouts. For non-piano tones, the polyphony is capped at 256, which is still generous.

In terms of tonal character, Roland pianos are known for their warmth and depth. Compared to Casio’s bright and clean sound, Roland feels rounder and more resonant, with a bit of “room” baked into the sound. This makes it especially satisfying for solo practice or expressive playing. Some might say that Roland tones feel darker than Casio’s, but they’re also richer and more complex.

Another huge advantage for Roland is variety. The F107 comes loaded with over 300 tones. While the main focus is still the piano, you also get a broad selection of electric pianos, synths, strings, pads, organs, and more. For players who like to experiment outside of classical piano, Roland offers far more creative options than Casio.

Direct comparison of sound character

When you play the PX-870 and F107 side by side, the contrast is clear. The Casio gives you a bright, articulate piano voice that works well for clarity, scales, and precise classical playing. It projects cleanly, which is useful for practice and learning, especially in educational settings where definition is important.

The Roland, meanwhile, gives you a more immersive sound, with a bloom and resonance that feels closer to sitting at an acoustic upright or small grand. The dynamic response is smoother, and it encourages more expressive playing. If you’re into romantic-era pieces, jazz ballads, or anything requiring nuance, Roland’s engine feels more rewarding.

That said, there are players who might prefer Casio’s clarity. Beginners, in particular, may appreciate how every note comes across distinctly without being buried in resonance. Roland’s warmer character can sometimes feel “muddier” if you’re not controlling your pedaling carefully.

How the sound engines pair with speakers

It’s important to remember that no sound engine exists in a vacuum—it’s always filtered through the piano’s speakers (or your headphones). The Casio PX-870’s stronger speaker system does help its AiR engine shine more than you’d expect. The Roland F107, with its weaker speakers, doesn’t fully showcase the power of the SuperNATURAL engine unless you use headphones or external amplification. We’ll cover speakers more deeply in their own section, but it’s worth keeping this context in mind here.

Through headphones, Roland’s advantage is more obvious. The nuances of the SuperNATURAL engine come through clearly, and the sense of realism is stronger. Casio still sounds very good, but Roland feels more alive and expressive when you’re listening closely.

Suitability for different players

For a student or hobbyist focused mainly on piano practice, Casio’s AiR engine delivers everything you need: clean tone, resonance modeling, and enough polyphony to cover any repertoire. The bright, precise sound can actually be an asset when you’re trying to develop accuracy.

For more advanced players, or anyone who values expressive tone and immersion, Roland’s SuperNATURAL engine is on another level. The smooth dynamic transitions, richer resonance, and sheer responsiveness make it feel closer to an acoustic instrument. Add the variety of additional tones, and Roland is clearly the more versatile choice.

Longevity and future-proofing

Another aspect worth mentioning is longevity. Casio’s AiR engine has been around for several years, and while it’s solid, it doesn’t feel cutting-edge anymore. Roland’s SuperNATURAL, though not brand-new either, has aged more gracefully because it’s based on modeling rather than just samples. Modeling allows more room for updates and refinements, whereas sample-based systems eventually hit a ceiling in realism.

This doesn’t mean Casio’s sound will “expire”—it still sounds great. But Roland’s approach feels like it has more staying power if you plan on keeping the instrument for many years.

Final thoughts on sound engine

Both Casio and Roland bring a lot to the table, but in different ways. Casio’s AiR sound engine is reliable, clear, and capable of producing a bright, articulate piano tone that works well for practice and performance in its class. Roland’s SuperNATURAL engine, however, goes further in realism, warmth, and expressiveness, making it the more satisfying choice for players who want an acoustic-like experience.

If your priority is clean sound and straightforward practice, the Casio PX-870 is excellent. But if you’re looking for tonal richness and musical immersion, the Roland F107 is the stronger choice.

Speaker System

A digital piano’s speaker system is often overlooked when people are comparing specs, but in reality, it plays a massive role in the playing experience. Even the best sound engine in the world won’t impress if it’s pushed through underpowered or poorly designed speakers. For many home players, the built-in speakers are the only way they’ll hear the instrument, so it’s worth examining closely.

The Casio PX-870 and Roland F107 take very different approaches here, and those differences can have a real impact depending on how and where you plan to use the piano.

Casio PX-870: A strong, immersive system

One of the standout features of the PX-870 is its 40-watt, four-speaker system. This is unusually powerful for a digital piano in its price category. Many competitors—including the Roland F107—offer far less wattage and fewer speakers, and that difference is immediately noticeable the first time you sit down to play.

The PX-870 has two 12 cm speakers and two smaller 4 cm speakers, placed in a way that directs sound both outward toward the player and upward into the room. The result is a surprisingly immersive and spacious sound for a slim console. You feel not only the notes in front of you but also the resonance spreading around the room, which is closer to how an acoustic piano projects.

In practice, this power makes the PX-870 more suitable for medium-sized rooms without needing external amplification. If you want to play for family or friends in a living room, the Casio can easily fill the space. Even at moderate volumes, the extra headroom prevents distortion and keeps the tone clear.

The tonal character through these speakers tends to emphasize clarity and brightness. Casio’s AiR engine already leans toward a clean, articulate sound, and the speaker system reinforces that. For classical practice and teaching, this is a plus, since every note comes across distinctly. However, some players may feel that the sound lacks a bit of warmth compared to Roland’s presentation.

Roland F107: Modest but refined

The Roland F107, by contrast, is equipped with a 24-watt, two-speaker system. On paper, this looks underwhelming next to Casio’s 40 watts and four drivers, and in terms of sheer power and fullness, it is. The F107’s speakers are adequate for personal practice and small rooms, but they don’t fill a space in the same way as the PX-870.

The two full-range speakers are housed in the cabinet and face forward. The sound is clear and pleasant, but the lack of upward projection makes the overall presentation feel more directional and less immersive. You’ll hear it well as a player sitting at the instrument, but if you step across the room, the sound loses some presence.

That being said, the character of the tone is worth noting. Because Roland’s SuperNATURAL engine is richer and more resonant, the F107’s speakers produce a warmer, rounder sound, even with less power. The result is a tone that can feel more organic at moderate volumes, even if it doesn’t have the same room-filling capacity as Casio.

For players who primarily use headphones or plan to connect to external speakers, the F107’s internal system is less of a drawback. But for those who want a self-contained experience without accessories, the weaker output may be disappointing.

Head-to-head comparison

When you directly compare the two pianos in the same room, the difference is obvious. The Casio PX-870 simply feels bigger and bolder. The sound wraps around you in a way that makes practice and performance more engaging. If you close your eyes, it does a better job of tricking you into thinking you’re at an acoustic instrument.

The Roland F107, while still clear and pleasant, comes across as more restrained. The warmth of the tone is nice, but the lack of body at higher volumes makes it feel like a smaller instrument. Push it too hard, and you may notice the sound compressing, something that doesn’t happen as quickly on the PX-870.

Practical considerations

There are a few practical things to keep in mind. The PX-870’s more powerful speakers can make mechanical key noise less noticeable, since the sound output easily masks the thumps of the action. On the F107, at lower volumes, you may be more aware of the keybed noise because the speakers aren’t overpowering it.

Both instruments include headphone jacks, which bypass the internal speakers altogether, but here again the experience differs. Roland’s SuperNATURAL engine shines more through headphones, where you can fully appreciate the nuances that the modest speaker system can’t always project. Casio’s AiR engine, while still clear and bright, doesn’t gain as much from headphone use—it already sounds very much the same through the onboard speakers.

If you’re in an apartment setting where you’ll often play at low volume, the Roland may feel more satisfying because of its warm tone, even with less power. If you want to play for others, or simply want the satisfaction of an enveloping sound at home, the Casio has a big advantage.

Suitability for different players

For students and casual players, the PX-870’s speaker system is a clear winner. It gives you the volume and clarity you need without external gear, and it makes practice sessions more inspiring. Teachers, too, may prefer the PX-870 in lesson settings, since its output is strong enough to be heard clearly across a room.

The Roland F107 is more about subtlety. It’s perfectly fine for personal practice, especially with headphones, and its warmer character may appeal to those who find Casio’s brightness a little sharp. But if built-in speaker performance is a deciding factor, Roland lags behind.

Final thoughts on speaker systems

The Casio PX-870 offers one of the best built-in speaker systems in its price category, with strong output, a spacious feel, and clarity that enhances its bright tone. The Roland F107, while producing a pleasant and warm sound, simply can’t match the Casio’s power and presence with its smaller 24-watt, two-speaker setup.

If you’re planning to rely on the piano’s own speakers most of the time, the PX-870 is the clear choice. If you’ll be using headphones or external amplification, the F107’s weaker speakers matter less, and you may even prefer its warmer tonal presentation.

In short:

• PX-870 is the better standalone experience.
• F107 is more dependent on headphones or external speakers to show its full potential.

Functions & Features

Beyond the keyboard and sound engine, digital pianos live or die by their functions and features. These are the extras that can make practice easier, broaden your creative options, and generally determine how flexible the instrument is. While both the Casio PX-870 and the Roland F107 keep things relatively streamlined compared to higher-end stage pianos or workstations, they still offer a solid range of tools. The key difference is in focus: Casio leans toward practicality and education, while Roland emphasizes versatility and modern connectivity.

Casio PX-870: Straightforward and practice-focused

The PX-870 doesn’t overload you with bells and whistles, but what it does offer is aimed at students, hobbyists, and home pianists who want a clean, distraction-free experience.

Instrument sounds
You get a total of 19 built-in tones. This includes multiple acoustic piano variations (concert grand, mellow piano, bright piano), electric pianos, organs, strings, harpsichord, vibraphone, and a few others. The focus is clearly on pianos, with the other voices acting as nice bonuses rather than serious performance tools. The quality of these secondary voices is decent but not stellar—good enough for casual use, but nothing groundbreaking.

Modes
Casio includes a few useful play modes:

• Layer mode: Combine two sounds at once, such as piano and strings, to add depth.
• Split mode: Assign one sound to the left hand and another to the right (e.g., bass on the left, piano on the right).
• Duet mode: Divide the keyboard into two identical ranges, allowing student and teacher to play together on the same piano. This is especially useful for lessons.

Recording and playback
The PX-870 includes a 2-track MIDI recorder, letting you record and layer two separate parts (such as left hand and right hand) and play them back. This is a handy tool for practice, composition, or self-evaluation. While limited compared to full DAWs, it’s simple and accessible for beginners.

Lesson features
Casio goes a step further by preloading the PX-870 with 60 built-in songs, mostly classical pieces. You can mute the left or right hand and play along, effectively practicing one hand while the other is played back for you. Combined with the duet mode, this makes the PX-870 a strong fit for a teaching environment.

Metronome and practice tools
The onboard metronome is easy to use and offers adjustable time signatures and tempo. While basic, it’s a must-have for students.

Concert Play
One standout feature is Casio’s Concert Play, which gives you 10 full orchestral recordings to play along with. This adds a sense of realism and fun to practice, making you feel like you’re performing with an ensemble. While it’s more of a novelty than a serious tool, it’s surprisingly motivating.

Other functions

• Transpose and tuning adjustment for playing in different keys or matching other instruments.
• Half-pedal functionality with the built-in triple pedal system, which is great for nuanced pedaling practice.
• Headphone mode optimization, which adjusts the sound for binaural listening and prevents ear fatigue during long sessions.

Overall, the PX-870 keeps its feature set focused on the essentials, with an educational slant. It’s not a digital playground, but it gives students and home pianists exactly what they need.

Roland F107: Feature-rich and modern

The Roland F107 takes a more expansive approach, especially in terms of sound variety and connectivity. While it doesn’t try to compete with high-end Roland models, it brings many of the company’s signature features into an affordable package.

Instrument sounds
Here, Roland has a clear advantage. The F107 comes with over 300 built-in tones, including a wide selection of acoustic and electric pianos, organs, strings, synths, pads, brass, guitars, and more. While the acoustic pianos are the main event, the sheer variety makes the F107 much more versatile for players who like to explore beyond traditional piano sounds. You can even use these voices to experiment with different genres or arrangements, which adds long-term value.

Modes
Roland includes all the standard modes—layer, split, and twin piano (their version of duet mode). The implementation is smooth, and thanks to the larger library of tones, layering and splitting feels more rewarding here than on the Casio. You can create more interesting combinations, such as electric piano with pads or organ with bass.

Recording and playback
The F107 supports MIDI recording like the Casio, but it also adds audio recording via USB. This means you can record your playing directly as a high-quality audio file to a USB stick or computer, without needing extra gear. For anyone wanting to share recordings, post performances online, or simply keep a log of progress, this is a big advantage over the PX-870.

Lesson features
Roland doesn’t preload the F107 with a big song library like Casio, but it does integrate seamlessly with Roland’s Piano Every Day and Piano Designer apps. Through these apps, you can access a wide range of lesson content, exercises, and even practice tracking. The app-based approach is more modern but does rely on having a smartphone or tablet handy.

Metronome and practice tools
As expected, the F107 includes a metronome, but the app integration makes it more versatile. You can adjust tempo and time signatures directly from the app interface, which is easier than navigating on the piano itself.

Customization and Piano Designer
One of Roland’s big selling points is Piano Designer, which lets you tweak deep aspects of the piano sound—hammer noise, string resonance, damper resonance, lid position, and more. It’s like being able to fine-tune your own virtual piano. For advanced players or those with a very specific taste, this level of customization is a game-changer. Casio offers some resonance control, but nothing on this level.

Other functions

• Bluetooth MIDI and audio: You can stream music wirelessly from your phone or tablet to the piano’s speakers, or use the piano as a MIDI controller without cables.
• Transpose and tuning functions, as with Casio.
• Twin headphone jacks, allowing two people to practice side by side silently.

The F107 feels more like a hybrid between a home piano and a lightweight creative tool. It’s geared not just toward practice, but also toward modern music-making and integration with other devices.

Head-to-head feature comparison

Casio PX-870:

• Strengths: Educational features, built-in song library, duet mode, Concert Play, simplicity.
• Weaknesses: Limited tone variety, no Bluetooth, no advanced customization.

Roland F107:

• Strengths: Huge tone library, Bluetooth connectivity, Piano Designer customization, audio recording, app integration.
• Weaknesses: Less self-contained—many features rely on external apps, fewer built-in learning tools.

Which set of features matters more?

If you’re a student or beginner, Casio’s features may actually serve you better. The onboard songs, simple recorder, and duet mode are all practical, classroom-friendly tools that don’t require extra devices. Teachers often prefer the straightforward setup.

If you’re a hobbyist, intermediate player, or someone who wants to make recordings, Roland’s feature set is far more appealing. The Bluetooth connectivity, audio recording, and massive tone library make it the more future-proof and versatile choice.

Final thoughts on functions and features

The Casio PX-870 takes a “less is more” approach, providing the essential functions for learning and practice without overwhelming the user. It’s an excellent fit for students and traditional pianists. The Roland F107, on the other hand, embraces modern connectivity and versatility. With hundreds of tones, advanced customization, and Bluetooth support, it appeals to players who want more than just a piano.

In essence:

• If you want a focused learning tool, go with Casio.
• If you want a modern, versatile creative hub, Roland is the better bet.

Connectivity

Connectivity is one of the most important aspects of a modern digital piano, though it’s often underestimated. At first glance, you might think of it as just a question of whether the piano has USB or not—but in reality, the quality and variety of connectivity options can determine how well the instrument integrates into your daily routine, your teaching environment, or your creative workflow.

This is especially true now that digital pianos are no longer just standalone instruments. They’ve become hubs that interact with apps, DAWs, external sound systems, headphones, and wireless devices. A piano with strong connectivity is easier to grow into, while a limited one can feel boxed in after a year or two of use.

Here’s how the Casio PX-870 and Roland F107 stack up.

Casio PX-870: Wired and traditional

The PX-870 takes a very classic approach to connectivity. It has all the essentials but little in the way of modern wireless features.

USB connectivity
The PX-870 offers USB Type B (to host) and USB Type A (to device) ports. The to-host port allows you to connect the piano directly to a computer or tablet and use it as a MIDI controller with software like GarageBand, Sibelius, or Ableton. This is a must-have for students using notation programs or hobbyists exploring recording.

The to-device port lets you plug in a USB stick to save or load MIDI files and even audio recordings. You can, for instance, record a performance on the piano, save it as a WAV file to the stick, and then transfer it to your computer. It’s not as seamless as direct-to-computer recording, but it’s practical.

Headphone jacks
Casio provides two headphone jacks, conveniently placed at the front underside of the keyboard. This is a thoughtful feature for students and teachers, since it allows two people to practice silently side by side. Headphone optimization mode, which adjusts the sound output for binaural listening, makes long practice sessions more comfortable.

Line outputs
The PX-870 doesn’t have dedicated line-out jacks, which is one of its main limitations. If you want to connect it to an external amp or PA system, you’ll need to use the headphone jacks with an adapter. This works fine for casual amplification but is not ideal for professional setups, since the signal can be noisier and harder to balance.

Pedals
One advantage of the PX-870’s design is that it comes with a built-in triple pedal unit (soft, sostenuto, and damper). These are integrated into the cabinet and don’t require external connections, which keeps things tidy. The damper supports half-pedaling for more realistic expression.

What’s missing
The big omission is Bluetooth. In 2025, the lack of Bluetooth audio and MIDI feels like a handicap. You can’t stream backing tracks wirelessly to the speakers, nor can you connect easily to mobile apps without a cable. For students using app-based learning tools, this adds friction.

Roland F107: Wireless and app-friendly

The Roland F107 is built with a much stronger emphasis on wireless connectivity, reflecting the company’s focus on integrating digital pianos with modern lifestyles.

Bluetooth MIDI and audio
This is one of the F107’s biggest selling points. With Bluetooth MIDI, you can pair the piano with your smartphone, tablet, or computer and instantly use it with music apps—notation apps, DAWs, or Roland’s own Piano Every Day and Piano Designer. No cables are required.

With Bluetooth audio, you can stream songs directly from your device to the piano’s speakers. This is a huge convenience for practice: you can play along with backing tracks, YouTube tutorials, or Spotify playlists without juggling cables or external speakers.

This feature alone makes the F107 feel more modern than the PX-870, and for younger players or hobbyists who live on their phones and tablets, it can be a decisive factor.

USB connectivity
The F107 also includes USB Type B to host and USB Type A to device ports, just like the PX-870. The difference is in how they’re implemented. When recording via USB, the F107 allows for both MIDI and audio transfer to a computer. That means you can record your performance directly into a DAW as an audio track, no need to bounce WAV files manually from a USB stick. This makes it far more efficient for musicians who want to create and share content.

Headphone jacks
Like Casio, Roland includes dual headphone jacks, also conveniently placed for teaching or silent duet practice. Roland adds 3D Ambience through headphones, which gives an impressively natural feel when practicing silently. It simulates the sense of being in a real acoustic space rather than hearing the sound pressed up against your ears. This is more sophisticated than Casio’s implementation.

Line outputs
Here’s where the F107 shares a weakness with the PX-870: it also lacks dedicated line-out jacks. For a piano in this price range, that’s not uncommon, but it does limit professional applications. If you want to play live with amplification, you’ll still be running from the headphone jack.

Pedals
The F107 includes a triple pedal unit, but unlike the Casio, it’s not built into the base—it’s a detachable unit that plugs into the piano. It’s still sturdy and functional, with support for half-pedaling, but it doesn’t feel quite as elegant as the PX-870’s integrated design. On the plus side, it’s replaceable if it ever breaks.

Head-to-head comparison

When you line them up, the differences in philosophy are clear:

• Casio gives you reliable wired connectivity, suited for traditional setups.
• Roland adds wireless convenience and deeper integration with apps, making it feel much more future-proof.

Casio’s omission of Bluetooth is glaring if you’re someone who likes using music apps or practicing along with tracks. For purely acoustic-style piano practice, it doesn’t matter much, but for modern players, it’s a noticeable limitation.

Roland’s implementation of Bluetooth MIDI and audio is not just a checkbox feature—it works smoothly, with low latency, and genuinely changes how you interact with the piano. The ability to stream music directly to the speakers or wirelessly connect to a notation app is something you’ll likely use every day.

Practical considerations

One important question is whether you see yourself using external devices frequently. If your main goal is straightforward piano practice without much tech involvement, the Casio’s wired connections will be plenty. It connects to a computer just fine, and the dual headphones make it practical for shared learning.

If you’re part of a modern household where tablets, phones, and apps are central to how you consume and learn music, the F107 integrates seamlessly. Roland’s ecosystem of apps, combined with third-party compatibility, makes it much easier to adapt to new tools as you progress.

Another consideration is recording. If you’re even remotely interested in recording your playing, Roland makes it easier. Direct audio transfer to a DAW is a huge time saver, while Casio’s method feels a bit clunky in comparison.

Final thoughts on connectivity

The Casio PX-870 is functional and reliable, but it feels a bit dated in this area. It does the basics—USB, headphones, pedals—but stops there. For students and traditional players, that’s fine. But if you want an instrument that grows with modern tech, it shows its age.

The Roland F107 is far more flexible. Its Bluetooth MIDI and audio, better headphone experience, and direct audio transfer over USB put it ahead by a wide margin. It’s designed for today’s connected musician, whether that’s a student practicing with apps, a hobbyist streaming backing tracks, or a creator recording performances.

In short:

• PX-870: Traditional, wired, dependable. Good for simple setups.
• F107: Modern, wireless, app-integrated. Better for long-term flexibility.

Conclusion

After spending time with both the Casio PX-870 and Roland F107, it’s clear that while they compete in the same price and category, they appeal to slightly different kinds of players. Both are excellent instruments in their own right, but their strengths lie in different priorities.

The Casio PX-870 is best described as a traditionalist’s digital piano. Its focus is on delivering a solid, acoustic-style experience for students, hobbyists, and anyone who wants a straightforward, reliable instrument for home practice. The design is elegant, the keyboard action is consistent, and the sound is warm enough to satisfy most ears. Educational tools like duet mode, Concert Play, and the built-in song library make it especially useful for learning. Where it falls short is in versatility: limited tone selection, no Bluetooth, and a somewhat old-fashioned connectivity setup mean it feels less future-proof. Still, for those who value simplicity and piano-focused functionality, it’s an excellent buy.

The Roland F107, on the other hand, feels like the more modern, versatile option. The sheer variety of tones, Bluetooth MIDI and audio, direct-to-computer audio recording, and the ability to customize sounds with Piano Designer make it a better fit for players who like to experiment, create, or integrate their piano into a broader tech ecosystem. Its sound engine is more nuanced, its connectivity more flexible, and its speaker system surprisingly powerful for its size. The main drawbacks are that it leans heavily on external apps for learning content and lacks built-in teaching songs like the Casio.

In the end, the choice comes down to priorities: go Casio for focused piano practice and education, choose Roland for versatility and modern features. Neither will disappoint, but one will almost certainly suit your lifestyle better than the other.
