Not a replacement, at least not officially

Roland announced the FP-40 in September 2026. The obvious assumption is that it replaces the FP-30X, which has been on sale since 2021. Roland has not said so. The FP-30X is still on Roland's product pages, and nothing Roland has published describes the FP-40 as its successor.

So the useful question is not "old or new". Both are current Roland portables, both carry the same keyboard, and they differ in a handful of specific places. Some of those differences favour the newer model, and some favour the FP-30X.

A note on method: this is a spec-based comparison. We have not played the two side by side. Every figure below comes from Roland's published specifications.

The part that did not change: the keys

Both pianos use Roland's PHA-4 Standard keyboard, which Roland lists for each model as having escapement and Ivory Feel key surfaces. On paper it is the same action. Roland's specification pages use the same wording for both: "PHA-4 Standard Keyboard: with Escapement and Ivory Feel". Both also give you 256-note polyphony.

That matters for how you read everything else. If you are choosing between these two, the feel under your fingers is not the deciding factor. Whatever you think of PHA-4 Standard, you get it either way. The decision comes down to sound, headphones, connections and size.

Sound: a different engine and a new speaker layout

The FP-30X uses Roland's SuperNATURAL Piano sound. The FP-40 uses what Roland calls the Piano Reality Sound Engine.

The speaker figures are close. The FP-30X has two 12 cm speakers driven at 11 W × 2. The FP-40 has two 8 × 12 cm speakers in a speaker box, driven at 12 W × 2. One extra watt per channel will not make either piano obviously louder in a living room. Whether the new speaker box changes how the piano sounds from the bench is a question for your own ears in a shop, not for a spec sheet.

The tone count moved in an unexpected direction. The FP-30X has 56 tones on its front panel, and Roland lists 321 in total when you use the Roland Piano App. The FP-40 has 40 tones on its panel and 305 in total, with the other 265 reachable only through the app. If you like choosing sounds from the piano itself without a phone, the older model gives you more of them.

Roland publishes no category breakdown for either list — no split into pianos, electric pianos, organs and the rest — so a list-against-list comparison of what each piano contains cannot be built from the specifications. Two things the figures do settle: the FP-40's list is the shorter of the two, and fewer of its tones can be selected without a phone. The piano sounds at the head of each list are not the same either, because the engines differ, SuperNATURAL Piano on the FP-30X and Piano Reality on the FP-40. That part is judged by ear in a shop, not from a table.

Headphones: the difference most likely to matter at home

This is the point we would check first.

The FP-30X has two headphone jacks: one stereo mini jack and one 1/4-inch (6.3 mm) jack. The FP-40 has one, a stereo mini jack that Roland labels "Phones/Headset", so it also takes a headset with a microphone.

For one person practising alone on earbuds or small headphones, the FP-40's single jack is no problem. It becomes a problem in two situations:

Neither is a deal-breaker, but both are the kind of thing people only notice after the box is open.

Connections: where the FP-40 is clearly newer

Both pianos have Bluetooth audio and Bluetooth MIDI, so both can play music from your phone through their speakers and connect to practice apps without a cable. The versions are different. Roland lists the FP-30X at Bluetooth 3.0 for audio and 4.0 for MIDI. The FP-40 uses Bluetooth 5.4 with classic A2DP audio, LE Audio and MIDI.

The FP-40 also adds built-in Wi-Fi, which the FP-30X does not have. Roland describes it as a way for the piano to join a home network and receive system updates. It works on the 2.4 GHz band only.

The learning side has shifted from the piano to the phone. The FP-30X has 30 internal songs. The FP-40 has 4, and Roland points instead to its Piano Sphere app, which it says offers 100 songs from day one. If you practise from a tablet on the music rest, that is a reasonable trade. If you would rather not involve a screen at all, the FP-30X keeps more on board.

Size, stand and pedals

Roland measures both with the music rest detached:

The FP-40 is almost 3 cm lower, which helps if you store the piano on a shelf or slide it away between sessions. It is also nearly 5 cm deeper, which matters on a narrow desk. Roland lists the FP-40 at 14.0 kg with the music rest, and on Roland's figures it is slightly lighter than the FP-30X. The gap is under a kilogram and will not change how either one is carried.

Neither includes a stand, and each has its own dedicated one: the KSC-70 for the FP-30X and the KSF-40 for the FP-40. Both come with a DP-2 pedal switch, and both list the KPD-70 three-pedal unit as an option. Neither runs on batteries.

Which one to choose

Choose the Roland FP-30X if more than one person will listen on headphones, if you own full-size headphones with a 6.3 mm plug, if you want more tones and songs available from the panel without an app, or if desk depth is tight.

Choose the Roland FP-40 if you practise alone on headphones or earbuds, if your practice already runs through a phone or tablet, if you want the newer Bluetooth with LE Audio and Wi-Fi updates, or if a lower profile helps you store it.

The keys are the same, so a shop visit should focus on what actually differs: the sound through the speakers, and whether the single headphone jack fits your household. If you are also weighing Yamaha, see our Roland FP-40 vs Yamaha P-225 and Roland FP-30X vs Yamaha P-225 comparisons.
