Who is this set-up for?

Four-hands duos

You share one keyboard and want to check whether its layout suits the score, or whether you need two matching playing ranges. Kawai describes the ES920 as having a Four Hands mode with two 44-key sections.

Duos sharing a rehearsal space

Your choice will partly depend on the built-in speakers, the audio equipment available and how well you can hear each other. Manufacturers list different speakers and connections for each model, so check the details for the instrument you’re considering.

Rehearsal pianists on the move

You take your instrument with you, so you’ll need to weigh up its keyboard and connections against what’s already available at the venue. Also check which stand, pedals and audio equipment you’ll need for your chosen set-up.

What should you look for?

Compare the score with your preferred playing set-up before choosing sound features or connections. This will help you work out whether one shared keyboard is enough or whether you each need your own.

What to consider What should you check? Who is this important for?
Keyboard layout Compare the highest and lowest notes in both parts with the available range. Kawai describes the ES920 as having two 44-key sections, while Yamaha specifies that the CP88 has an 88-key keyboard. If you want to know whether both parts will fit on one keyboard, start by checking its layout; around 33% of consumers say this is their top buying priority.
Being able to hear each other Ask what speakers, monitors and connections are available. Roland lists built-in speakers for the RD-88, while Korg says the Grandstage X has no built-in speakers. If you both need to hear clearly, find out what audio equipment the room requires; around 27% of consumers put being able to hear each other first.
Transport and set-up Check the dimensions and stated weight of the exact model, as well as the stand and equipment you’ll need. Yamaha specifies that the CP88 is 1,298 mm wide and weighs 18.6 kg. If you transport the instrument between rehearsal spaces, find out in advance what you’ll need to bring and set up; around 20% of consumers give transport and set-up top priority.
Touch and pedals Try out passages together and check which pedal controls suit the playing mode. Yamaha lists an NW-GH3 keyboard and an included FC3A pedal for the CP88; Kawai documents an F-10H damper pedal for the ES920. If your parts call for a particular touch or pedal set-up, you’ll want to try it together; around 20% of consumers put playing feel and pedals first.

Common pitfalls

  • Confusing a split function with a duo mode

    A standard split divides the keyboard, but that doesn’t mean both players get the same range. Some notes in the score may then fall outside the range of one of the sections.

    Look for a clearly described duo or four-hands mode, and compare the key limits with both parts.

  • Assuming every stage piano has built-in speakers

    Korg says the Grandstage X has no built-in speakers, while Roland lists them for the RD-88. Without suitable audio equipment, a model without speakers won’t be audible on its own in the room.

    Check the audio outputs on the exact model and ask what equipment and cables are available in the rehearsal space.

    A set-up with external audio may require extra equipment and time to connect and adjust.

  • Assuming one headphone socket is enough for two players

    The specifications for the Yamaha CP88 and Nord Piano 6 each list one headphone output, not two separate sockets.

    Work out in advance how you can both listen at the same time, and check what listening equipment you’ll need.

    A shared listening set-up may involve extra equipment and connections.

  • Planning only for the instrument, not the shared playing set-up

    A portable instrument doesn’t guarantee that the stand, seating and pedal controls will work for two players. Kawai lists compatible pedal options for the ES920.

    Try the set-up with both players and check which accessories and pedal controls suit the way you’ll use each model.

    You may need to bring and set up extra items, such as a stand, seating or suitable pedal accessories.

Brands to consider

Roland

RD stage pianos are worth considering if you’re looking for portability and adjustable sounds or zones for rehearsals.

  • Roland lists built-in speakers for the RD-88 and documents split controls for the RD-88 EX.
  • A split function doesn’t show that both players will have the same range.

Yamaha

The CP88 is an 88-key stage piano for players looking for a full keyboard and connections for a studio set-up.

  • Yamaha specifies balanced XLR outputs and unbalanced jack outputs.
  • The specifications list one PHONES socket and don’t document two headphone sockets or a duo mode.

Kawai

The portable ES920 digital piano is an alternative if two similar playing ranges matter more to you than an instrument from a stage piano range.

  • Kawai documents a Four Hands mode with two 44-key sections and built-in speakers for the ES920.
  • Each player has fewer physical keys in this mode, so check that the parts and pedal controls will work for you.

Korg

The Grandstage X suits a studio with external audio and a need for adjustable stage sounds.

  • Korg specifies split and layer controls, as well as XLR and jack outputs.
  • According to Korg, the Grandstage X has no built-in speakers; a split isn’t automatically a duo mode.

Nord

The Nord Piano 6 88 is a stage-focused option for players who want to use layered sounds and a weighted 88-key keyboard for duet rehearsals.

  • Nord specifies two piano layers and two synth layers, split points and an included Nord Triple Pedal 2.
  • The specifications list one headphone output and don’t show two independently mirrored playing ranges.

Frequently asked questions

Is a standard split function the same as a duo mode?

No. A split divides the keyboard, but that doesn’t mean both sections have the same range. Kawai describes a Four Hands mode with two 44-key sections for the ES920; check that this range suits the score.

How do you set up a stage piano without speakers in a rehearsal space?

Use suitable external audio equipment and check the available inputs and the cables you’ll need in advance. Korg says the Grandstage X has no built-in speakers.

Can both players connect a pair of headphones?

That depends on the connections and listening set-up. The specifications for the Yamaha CP88 and Nord Piano 6 each list one headphone output, so check how two players can listen at the same time.

Can I return a piano bought online in the Netherlands within 14 days?

For a standard online consumer purchase, you generally have a statutory cooling-off period of up to 14 days after delivery. ACM ConsuWijzer explains the exceptions; check whether they apply to your specific order.

What should I do if the piano develops a fault after I buy it?

Report the problem to the seller. According to the Dutch Government, there is no fixed statutory guarantee period in the Netherlands; what you can expect from the product depends on the circumstances. A manufacturer’s guarantee does not replace your statutory rights.
