Yamaha PSR-SX920 vs. PSR-SX720+: The Real-World Difference Between a Great Arranger and a More Complete One

 

If you are comparing Yamaha’s PSR-SX920 with the newer PSR-SX720+, the easy answer is to look at the specification sheet, count the Voices and Styles, and declare the SX920 the winner.

That would also miss the point.

The more interesting question is not “Which keyboard has more?” It is:

Where will you actually notice the difference when you are sitting behind the keyboard, rehearsing at home, playing in a church, accompanying a singer, performing at a party, or working a live gig?

That is where the distinction between these two Yamaha arrangers becomes much clearer.

The PSR-SX720+ is not simply a lesser SX920 with fewer sounds. It is a remarkably capable arranger that now adds Bluetooth Audio, while retaining the modern SX-generation architecture, Style Dynamics Control, Super Articulation technologies, Chord Looper, a touchscreen interface, and a surprisingly serious collection of performance tools. Yamaha introduced the SX720+ in 2026 specifically as an expansion of the SX720 concept with Bluetooth audio connectivity.

The SX920, however, moves into a different territory once you start using its additional effects, expanded sound library, greater expansion capacity, more sophisticated vocal functionality, additional outputs, and more powerful live-performance capabilities.

In other words:

The SX720+ is the keyboard that gives you most of the experience.
The SX920 is the keyboard that gives you more headroom.

And depending on the musician, that difference can be either enormous—or almost irrelevant.

 

 

First, Let's Establish What the PSR-SX720+ Actually Is

The word “Plus” is important.

The original PSR-SX720 was already a serious 61-key arranger. The new PSR-SX720+ retains the core architecture but adds Bluetooth Audio, allowing a phone, tablet, or other compatible Bluetooth source to stream audio directly through the keyboard. Yamaha specifically positions this as useful for playing along with music, practicing, and exploring musical ideas.

That sounds like a small convenience.

In practice, it can be much more useful than that.

Imagine a musician learning a song from YouTube, Spotify, a rehearsal recording, or a phone-recorded performance. Instead of connecting another cable or routing the phone through a separate mixer, the backing audio can come through the keyboard itself.

For the home musician, that is extremely convenient.

For a teacher, it can simplify lessons.

For a performer, it can be useful during rehearsal.

And for someone who uses the keyboard as the centerpiece of a small home setup, it makes the SX720+ feel considerably more modern than the specification sheet might suggest.

Interestingly, the SX920 also has Bluetooth Audio, so the SX720+ does not have an exclusive advantage here. The significance is that Yamaha has now brought that functionality down into the SX720 tier.

The Numbers: SX720+ vs. SX920

On paper, the difference looks substantial.

Feature	PSR-SX720+	PSR-SX920
Keys	61	61
Polyphony	128	128
Preset Voices	1,377	1,587
Drum/SFX Kits	56	63
XG Voices	480	480
Expansion Voice Memory	Approx. 1 GB	Approx. 2 GB

Main Outputs	L/L+R, R	L/L+R, R
Additional Sub Outputs	No	Yes
Bluetooth Audio	Yes	Yes
Internal Memory	Approx. 1 GB	Approx. 4 GB
Display Out	No	Yes

Yamaha's current specifications show both instruments using 128-note polyphony, four keyboard parts—Right 1, Right 2, Right 3 and Left—and the same 61-key FSB-style keyboard mechanism. The big differences emerge in the sound library, Styles, effects, expansion capacity, vocal processing, storage and connectivity.

And this leads to the first important real-world observation:

The SX920 Does NOT Feel Like Twice the Keyboard

This is something prospective buyers should understand.

The SX920 is not twice as good as the SX720+.

In fact, if you play the two casually in a music store, you could easily come away thinking:

“These are remarkably similar.”

And you'd be right.

Both keyboards share the same basic 61-key format, touchscreen interface, 128-note polyphony, four-part keyboard architecture, joystick, two assignable knobs and eight assignable panel buttons. Both have the same fundamental arranger philosophy.

Both are capable of producing a surprisingly complete band from a single keyboard.

That is why the SX720+ represents such a strong value.

The SX920's superiority becomes apparent when you stop asking “Can it do this?” and start asking:

“How much more can I do with it before I hit its limits?”

Sound: Where the SX920 Starts Pulling Away

The SX720+ has 1,377 Voices, while the SX920 has 1,587 Voices. Both also include 480 XG Voices, but the SX920 has considerably more of Yamaha's premium articulated sounds.

That difference should not be interpreted as:

“The SX920 has 210 sounds that the SX720+ can't live without.”

Most players will never use hundreds of their keyboard's sounds.

The real difference is selection quality and specialization.

The SX920 offers:

• 12 S.Articulation2 Voices
• 15 S.Articulation+ Voices
• 340 S.Articulation Voices
• 82 MegaVoice Voices
• 55 OrganFlutes

The SX720+ offers:

• 9 S.Articulation+ Voices
• 252 S.Articulation Voices
• 54 MegaVoice Voices
• 55 OrganFlutes

What does that mean when you're actually playing?

It means the SX920 gives the arranger player more convincing ways of making an arrangement sound performed rather than programmed.

This becomes particularly noticeable with guitars, brass, saxophones, strings and other instruments where articulation is crucial.

A normal sampled guitar note is just a guitar note.

An articulated guitar can respond more like a guitarist.

A saxophone patch that incorporates realistic articulations can sound dramatically more convincing when used in a melody.

And this is precisely the territory where Yamaha's Super Articulation system earns its reputation.

The Difference You Hear Isn't Always the Sound—It's the Arrangement

This is perhaps the most overlooked distinction.

A professional arranger keyboard is not simply a giant synthesizer.

The Styles matter.

The SX720+ comes with 450 Styles, including 410 Pro Styles, 37 Session Styles and 3 Free Play Styles.

The SX920 expands that to 575 Styles, including 520 Pro Styles, 49 Session Styles and 6 Free Play Styles.

That is not merely 125 additional buttons on a menu.

Styles are the foundation of how these keyboards create the illusion that you are playing with a band.

The drummer changes.

The bass player changes.

The guitar accompaniment changes.

The harmonic accompaniment changes.

Fill-ins appear.

Variations develop.

Endings resolve.

And the keyboard player sits in the middle of it all.

For someone who plays Latin, Caribbean, pop, ballroom, gospel, country, jazz, dance music or international styles, having the right accompaniment pattern can matter far more than having another 200 individual Voices.

This is why the SX920's larger Style library becomes valuable to the working arranger, rather than necessarily being important to the casual player.

But Here Is Where the SX720+ Gets Interesting

Yamaha did not simply make the SX720+ a stripped-down keyboard.

The middle-tier model received some very serious technology.

The SX720+ has Style Dynamics Control, which allows the performer to manipulate the energy and dynamics of the accompaniment. It also has newly added Style Insertion DSP capability, along with Super Articulation Plus Voices and Crossfade Portamento.

This matters in live performance.

A conventional arranger can sometimes sound like:

START → accompaniment plays → fill → variation → ending.

A more sophisticated arranger allows the musician to shape the accompaniment while it is happening.

That's a fundamentally different performance experience.

You can make the accompaniment feel restrained during a verse and more aggressive as the chorus arrives.

That means the keyboard becomes less like a playback machine and more like an instrumental conductor.

Chord Looper: One of the Most Practical Features on Both

Both keyboards include Yamaha's Chord Looper.

This is one of those features that sounds like a gimmick until you actually use it.

You can record a chord progression and have the keyboard repeat it while your hands are freed up to play something else. Yamaha says the SX920 can store up to eight chord sequences in each bank, with unlimited banks available.

Think about what that means.

You can establish a progression with the left hand:

Am → F → C → G

Then let the keyboard cycle those chords while you play:

• a piano melody,
• a sax solo,
• a guitar line,
• a synth lead,
• an organ part,
• or both hands across the keyboard.

For songwriting, practice and live performance, this can fundamentally change how you interact with an arranger.

And importantly, this is not an SX920-only luxury.

The SX720+ also has Chord Looper.

That's another reason why the SX720+ deserves more respect than its position in Yamaha's lineup might suggest.

The Biggest SX920 Advantage: Effects and Processing

Here is an area where the SX920 becomes much more compelling to experienced players.

The SX720+ provides 322 DSP presets and up to 9 insertion-effect blocks.

The SX920 increases that to 358 DSP presets and 13 insertion-effect blocks, including VCM-based effects.

To a beginner, this can look like meaningless engineering trivia.

To a player who builds sophisticated registrations, it is potentially very important.

Effects are what help determine whether multiple sounds feel like they belong together.

A piano can sit differently in the mix.

A guitar can have its own processing.

A saxophone can receive appropriate effects.

A layered synth can have its own character.

And the SX920 gives the arranger more processing architecture with which to build these combinations.

This is one of those differences you may not appreciate while auditioning the keyboards for five minutes.

But after six months of gigging?

You may appreciate it every night.

Vocalists: This Is Where the SX920 Becomes a Different Class

If you sing while playing, pay very close attention to this section.

The SX720+ has microphone/guitar effects, including noise gate, compressor and three-band EQ.

The SX920 goes substantially further.

It adds:

• 54 Vocal Harmony presets
• 20 Synth Vocoder presets
• 60 total user settings across Vocal Harmony and Synth Vocoder

That is not a cosmetic upgrade.

It changes the potential role of the instrument.

For a singer/keyboardist performing solo, the SX920 can become the center of the entire musical setup.

You can play the accompaniment.

You can sing.

You can process the microphone.

You can generate vocal harmonies.

You can build the arrangement around yourself without necessarily needing a second musician.

For a vocalist who regularly performs alone, this feature alone can justify moving from the SX720+ to the SX920.

For someone who never plugs a microphone into the keyboard?

It may be practically worthless.

That's an important distinction.

Connectivity: The SX920 Is Designed More Like a Performance Hub

Both keyboards have MIDI IN/OUT, USB TO HOST, USB TO DEVICE and a stereo AUX input.

But the SX920 adds a much more flexible output configuration.

The SX720+ provides the main stereo outputs.

The SX920 provides:

MAIN OUTPUT L/L+R and R

plus:

SUB/AUX OUTPUT 1 and 2

That sounds technical.

On stage, it isn't.

Imagine you are playing through a professional sound system.

You might want:

Main L/R → front-of-house

while routing another signal independently for a separate purpose.

Perhaps you want an external processor.

Perhaps you want a recording feed.

Perhaps you need a different routing arrangement for a complicated stage setup.

The SX920 gives you more options.

The SX720+ is perfectly usable for normal stereo PA operation.

The SX920 simply gives the professional user more ways to integrate the keyboard into a larger system.

Internal Memory: Another Difference You Won't Notice on Day One

The SX720+ has approximately 1 GB of internal expansion memory.

The SX920 has approximately 2 GB of expansion Voice capacity, while Yamaha lists approximately 4 GB of internal memory for the SX920 compared with approximately 1 GB for the SX720+.

Again, the casual user might never care.

But serious arranger players accumulate material.

Expansion packs.

Custom Voices.

Styles.

Registrations.

Performance setups.

Songs.

Personalized libraries.

The more you customize the keyboard, the more valuable internal storage becomes.

This is the difference between a keyboard that is excellent out of the box and a keyboard that gives you more room to turn the instrument into your instrument.

And Then There Is Display Out

Another feature that is easy to overlook:

The SX920 supports an external display through a compatible USB display adapter.

The SX720+ does not list display output capability.

For someone playing at home, this might mean absolutely nothing.

For a performer using lyrics, registration information or other visual material on stage, it can be considerably more useful.

Once again, the theme emerges:

The SX720+ gives you the core experience.
The SX920 gives you more infrastructure around that experience.

What About Bluetooth?

The new SX720+ finally answers one of the most obvious modern complaints about the previous SX720: Bluetooth Audio is now built in.

You can stream audio from a compatible smartphone or tablet directly into the keyboard. Yamaha explicitly describes the feature as allowing users to play along with their favorite songs and record what they hear using the built-in audio recorder.

This is particularly useful for:

Practicing

Put your favorite recording on your phone, connect it to the SX720+, and play along.

Learning songs

Slow down or manipulate your practice material using compatible audio functions and work through difficult sections.

Rehearsal

Instead of setting up another playback device and cable, your keyboard becomes the playback system.

Songwriting

Play a reference track while experimenting with new chord progressions, melodies or arrangements.

Demonstrations

A salesperson, teacher or musician can quickly demonstrate the keyboard against an existing recording.

This is not a reason by itself to buy the SX720+ over the SX920 because the SX920 also has Bluetooth Audio.

But it is a major reason why the “Plus” designation matters.

The Speakers: Surprisingly Important in Real Life

Both keyboards have built-in amplification, but the configuration differs.

The SX720+ uses two 15-watt amplifiers with 13 cm speakers and 5 cm units.

The SX920 uses two amplifier sections rated at 15 W + 10 W, with 13 cm speakers plus 2.5 cm dome tweeters.

The important practical point isn't simply wattage.

The SX920's speaker system is designed to provide a more sophisticated frequency presentation.

If you are playing through headphones or a PA system, the difference becomes less central.

But if you are sitting in your living room playing the keyboard through its internal speakers, you are listening to this system every single day.

For home musicians, that matters.

Who Should Actually Buy the SX720+?

The SX720+ is the logical choice for a surprisingly large number of musicians.

Choose the SX720+ if you are:

A home player

You get an enormous arranger engine without paying for features you may never use.

A hobbyist

You have enough Voices, Styles, effects and performance controls to spend years exploring the instrument.

A beginner moving into serious arranging

The SX720+ gives you room to grow without immediately throwing the entire professional feature set at you.

A church musician

Unless you specifically need the SX920's advanced vocal processing, expanded outputs or particular Voices/Styles, the SX720+ is already extremely capable.

A singer who doesn't need built-in vocal harmonization

The SX720+ still provides useful microphone processing.

A mobile musician

The 61-key format, relatively compact dimensions and 11.6 kg / 25.6 lb weight make it manageable for transportation. The SX920 is essentially the same physical size and weight, so this isn't a major difference between the two, but both remain reasonably portable for their class.

A musician who wants Bluetooth without jumping to the higher model

This is perhaps the most obvious target for the new Plus model.

Who Should Spend More on the SX920?

The SX920 makes more sense when the keyboard isn't merely an instrument for playing at home.

Choose the SX920 if you are:

A professional arranger

The larger Style and Voice libraries, expanded DSP architecture and additional memory provide more creative headroom.

A solo performer

Especially if you sing, the Vocal Harmony and Synth Vocoder capabilities can dramatically increase what you can do without additional equipment.

A gigging keyboardist

The additional outputs and expanded performance architecture become increasingly valuable as your rig becomes more complicated.

A musician who heavily uses expansion packs

The additional memory gives you more room to build a large customized library.

A player who cares about detailed articulation

The additional S.Articulation and MegaVoice content can matter when realism is the priority.

A serious production-oriented arranger

The additional DSP capability, effects architecture, storage and connectivity give the SX920 more room to grow with you.

The Most Important Question: Is the SX920 Worth the Extra Money?

There is no universal answer.

And anyone who tells you that there is probably isn't thinking about how musicians actually use these instruments.

If you are comparing the two strictly by capability, the SX920 wins.

If you are comparing them by value, the SX720+ becomes extremely difficult to dismiss.

The SX720+ already has:

• 128-note polyphony
• 1,377 Voices
• 450 Styles
• Super Articulation technology
• Style Dynamics Control
• Chord Looper
• 7-inch touchscreen
• 8 assignable buttons
• 2 assignable knobs
• Bluetooth Audio
• microphone/guitar input
• USB/MIDI connectivity
• expansion capability
• 128-note polyphony
• 61 keys

That is not an entry-level arranger.

It is a serious instrument.

The SX920 simply gives the experienced player more places to go.

The “80/20” Reality

For many musicians, the SX720+ may deliver something like 80–90% of the practical experience they actually need from the SX920.

But that remaining 10–20% can be extremely important if it contains the exact feature you require.

If you never sing through the keyboard, Vocal Harmony doesn't matter.

If you never use external outputs, additional routing doesn't matter.

If you don't install large expansion libraries, additional memory doesn't matter.

If you don't build sophisticated registrations with extensive effects, the additional DSP blocks may not matter.

If you don't need particular SX920 Voices or Styles, the larger library doesn't matter.

And suddenly, the SX720+ starts looking like an incredibly rational purchase.

Conversely, if you do need those features, the SX920 isn't merely “a little better.”

It is the correct tool.

The Bottom Line

The Yamaha PSR-SX720+ is the keyboard I would recommend to the musician who wants a modern, extremely capable arranger without paying for professional-level features they may never exploit.

It is powerful enough to perform with, sophisticated enough to arrange with, flexible enough to customize, and now modern enough to integrate Bluetooth Audio directly into the instrument.

The Yamaha PSR-SX920, meanwhile, is for the player who has moved beyond asking “What can this keyboard do?” and has started asking “How far can I push it?”

The SX920 gives you more articulated Voices, more Styles, more DSP capability, more memory, advanced vocal processing, additional outputs and external display support.

But perhaps the fairest way to describe the two is this:

PSR-SX720+

The smart buy.

You get an enormous amount of Yamaha arranger technology without paying for capabilities that may sit unused.

PSR-SX920

The long-term buy.

You spend more, but you gain the headroom that becomes valuable when your performances, arrangements and technical demands become more sophisticated.

And that is ultimately the difference.

The SX720+ isn't the keyboard you buy because you can't afford the SX920.

It can be the keyboard you buy because it already does almost everything you actually need.

The SX920 is what you buy when you know exactly what the remaining capabilities are—and know that you will use them.

That distinction is far more useful than simply saying one is the “better” keyboard.

Because in the real world, the best keyboard isn't the one with the longest specification sheet.

It's the one that gives the musician exactly enough instrument to stop thinking about the equipment—and start thinking about the music.
