For a duet where players need to use each other’s registers, playing together across the full keyboard is the starting point; Duo or Twin Piano mode is designed to create two similar playing areas. For quiet practice, two headphone sockets are useful, while a stage piano designed for live performance is a good fit if its sound controls and studio connections matter more than the possibility of needing a more extensive listening set-up.
You want to play different parts at the same time. So consider whether the parts, touch response and seating space work on one full keyboard; a mode that splits the keyboard isn’t automatically necessary. Yamaha describes Duo for the P-225, while Roland offers Twin Piano on the FP-30X.
You both want to listen through headphones, rather than relying on the built-in speakers. Roland lists dual headphone outputs for the FP-30X, while Kawai lists two sockets for the ES120.
You want to connect the piano to your existing audio equipment and control layers or splits while playing. Compare the connections and controls on the specific models: features available on one stage piano aren’t automatically available on another.
Best for: two players who want to use similar halves of the keyboard as well as play duets. Yamaha lists Duo for the P-225, while Roland lists Twin Piano for the FP-30X.
Bear in mind: the mode splits one keyboard; it doesn’t give you a second full keyboard. Try your duet parts on the full keyboard and assess the practice mode separately.
Best for: two players who want to listen quietly at the same time. Roland lists dual outputs for the FP-30X, while Kawai lists two headphone sockets for the ES120.
Bear in mind: having two sockets doesn’t in itself mean you can adjust the volume or mix separately. Also check that both pairs of headphones have compatible plugs.
Best for: players who want to control layers and splits, or connect a piano to an existing studio set-up. Yamaha lists jack and XLR line outputs for the CP88; Roland describes zones for layers and splits on the RD-88 EX.
Bear in mind: a split for different sounds isn’t automatically a duet practice mode. Yamaha lists one headphone output for the CP88, so also consider how two players will listen together.
| Consideration | What should you check? | Who is this most relevant to? |
|---|---|---|
| Keyboard layout and playing together | Play both parts together across the full keyboard. Try Duo or Twin Piano mode separately, and consider seating space and pedal use. | If your duet parts use each other’s registers, playing across the full keyboard is essential. Around 36% of consumers in this situation prioritise this duet arrangement. |
| Listening quietly at the same time | Check the number of headphone outputs, plug sizes and whether you need separate volume control. | If you want to practise together without relying on the speakers, check how both pairs of headphones can be connected. Around 29% of consumers prioritise listening together quietly. |
| Connections and controls | Make a note of the audio and MIDI connections your studio needs, and compare them with the exact model variant. | If you want to use the piano with existing studio equipment, its connections and sound controls need to suit your set-up. Around 21% of consumers prioritise studio integration. |
| Space and complete set-up | Measure the space with your intended stand and seating. Check which pedals and other components come with the version you’re considering. | If space is limited or you need a complete duet set-up, don’t measure the piano body alone. Around 14% of consumers prioritise space and the complete set-up. |
These practice modes split the keyboard between two players. A duet may instead require both players to use each other’s registers.
Play your own parts together across the full keyboard before treating the practice mode as a reason to buy. Yamaha describes Duo for the P-225, while Roland describes Twin Piano for the FP-30X.
The Yamaha CP88 and Nord Piano 6 each list one headphone output, while Roland lists two for the FP-30X and Kawai lists two for the ES120. Check the connections on the exact model.
Plan your listening set-up for two people, and check the plugs and whether you need separate volume control.
The piano body doesn’t tell you how much room the complete duet set-up will need, including two seats, a stand and pedals. Yamaha lists the three-pedal unit for the P-225 as an optional extra.
Measure the available space with your intended set-up, and check which pedals and components are included with the version you choose.
The P-225 and CP88 represent different ways to play: a portable digital piano with Duo, compared with a stage piano designed for live performance.
The FP-30X is worth considering for practising together, while the RD-88 EX is designed for sound zones and studio connections.
The ES120 is a portable digital piano worth considering if you want two headphone sockets and separate stereo line outputs.
The Nord Piano 6 is worth considering if you want to control splits and piano layers while playing.
The compact Privia PX-S1100 is another option to compare for a small home studio.
Not necessarily: this mode divides the keyboard for players who each want a similar playing area. First try your duet on the standard full keyboard, then assess the practice mode separately.
Check that both pairs of headphones fit the outputs on the exact model. Roland lists dual outputs for the FP-30X; the Kawai ES120 manual describes connections for a stereo mini plug and a standard stereo plug that can be used at the same time.
Follow the manual for your chosen model for power and positioning instructions. The Kawai ES120 manual specifies the stated mains voltage and the supplied adapter intended for this instrument, and warns against moisture and damaged cables. This is manufacturer guidance for the ES120.
If a product doesn’t meet reasonable expectations, the seller must offer a solution. According to the Dutch government, the Netherlands has no fixed statutory guarantee period; a manufacturer’s guarantee is in addition to your statutory rights.
When buying at a distance from a business, you usually have a 14-day cooling-off period. The Dutch government notes that there are exceptions and, among other things, distinguishes these purchases from those made from a private seller; check which rules apply to your purchase.
