The question Yamaha PSR-SX720+ or PSR-SX920 comes up for almost everyone moving from an entry-level keyboard to a full arranger. Both belong to the SX series, share the 61-key layout and the 7-inch color touchscreen, and then clearly part ways on sound range, speakers and pro features. The plus in the name marks the April 2026 update: it adds Bluetooth audio, while the rest of the specification stays the same as on the previous PSR-SX720.
This comparison sorts out the real differences instead of listing spec sheets. By the end you will know whether the SX720+ is enough as an all-round arranger or whether the step up to the SX920 is worth it for you.
The versatile arranger for the living room and first gigs
Ideal for: Hobby players, home users and entry-level entertainers who want a full arranger without the pro surcharge.

Ideal for: Semi-pros and entertainers who need maximum sound, more styles, stronger effects and sampling.

Both models share the essentials of the SX platform: 61 touch-sensitive but unweighted keys, a clearly readable 7-inch color touchscreen and the intuitive Yamaha arranger control with style sections, multi-pads and registration memory. Anyone coming from a PSR-E keyboard will feel at home on either.
The core idea is identical too: an auto-accompaniment that turns a played chord sequence into a full band. The differences lie in how rich and how professional that sound becomes.
02Sound, voices and styles – the heart of the difference
The PSR-SX720+ offers around 1,377 voices and 450 styles, a range that is more than enough for most genres and a varied evening. The PSR-SX920 raises that to around 1,587 voices and 575 styles, and adds Super Articulation 2 sounds as well as sound material derived from Yamaha's flagship Genos.
In practice this means solo instruments such as saxophone, trumpet or guitar sound even more lifelike on the SX920, because articulations and playing noises are rendered more finely. For pure home accompaniment the difference is audible but rarely decisive; on stage and in a direct comparison it shows more clearly.
03Speakers, effects and connectivity
On the speaker system the SX920 takes the lead: it is built for more powerful, room-filling playback, while the SX720+ is sized for the living room and smaller spaces. If you mostly play through a PA system anyway, this point matters less.
The gap is clearer in the effects section: the SX920 processes more DSP effects at once, allowing more complex sound design and denser arrangements. It also has a built-in USB audio interface, letting the SX920 work directly as an audio source on a computer; the SX720+ needs a separate interface for that. The expansion memory for your own sound and style packs is 2 GB on the SX920, double the SX720+'s 1 GB.
| Feature | PSR-SX720+ | PSR-SX920 |
|---|---|---|
| Voices | approx. 1,377 | approx. 1,587 |
| Styles | approx. 450 | approx. 575 |
| Super Articulation 2 | no | yes |
| Genos-derived sounds | selection | more extensive |
| Speaker system | for the living room | stronger, room-filling |
| Simultaneous DSP effects | fewer | more |
| Built-in USB audio interface | no | yes |
| Expansion memory | 1 GB | 2 GB |
04Which model for whom – the recommendation
The PSR-SX720+ is the right choice if you play at home, perform occasionally in smaller settings and want a full arranger without the pro surcharge. You get the Yamaha arranger comfort, a broad style selection and built-in sound reinforcement that is enough for the living room and first gigs.
The PSR-SX920 pays off if you regularly play on stage, want the full sound range, shape sounds with effects and load your own expansion packs. The extra cost goes into more voices and styles, stronger speakers, more DSP, the audio interface and double the memory. As a rule of thumb: hobby and home favor the SX720+, semi-pro and entertainment favor the SX920. You will find both in our Keyboards category.
Both Yamaha arrangers are well-considered instruments: the choice depends on your demands, not on a shortcoming of the cheaper model. The SX720+ is the versatile all-rounder, the SX920 the no-compromise pro variant.
