First, decide how you want to listen: for quiet practice, a suitable headphone socket is important, while built-in speakers are useful if you want to rehearse audibly without an extra monitor. A model without speakers may suit you if you already have external monitoring. Then compare the transpose controls, sound changes and playing feel. The model features mentioned are based on manufacturers’ specifications, not independent playing tests.
You’re learning parts in a shared living space and want to play with headphones, but sometimes practise without separate speakers too. Roland, Yamaha and Korg describe models with different listening options.
You’re learning songs in different keys for singers and want to switch settings or sounds quickly during rehearsals. Roland describes direct access to transposition and recallable Scenes on the RD-08; Korg lists a transpose button on the D1.
You already have monitoring for audible rehearsals, so you could also consider a piano without built-in speakers, provided its connections work with your equipment. Korg lists line outputs and a headphone output on the D1.
Start with your listening setup: this determines whether you need built-in speakers or whether headphones and your own monitoring will do.
A good fit if: you want to alternate between practising with headphones and rehearsing audibly with a singer, without bringing a separate monitor. Roland lists speakers and direct access to transposition on the RD-08; Yamaha lists speakers and a headphone output on the CK88.
Trade-off: if you only play piano accompaniment, you may not need all the sound sections on the CK88. A microphone input also doesn’t replace assessing the complete vocal and sound setup.
A good fit if: you practise with headphones and already have suitable active speakers or a mixer for audible rehearsals. Korg lists a headphone output, line outputs and a transpose button on the D1.
Trade-off: the D1 has no built-in speakers; without headphones or external sound equipment, you won’t hear the piano.
A good fit if: piano playing and practice in one place matter more to you than direct stage controls. Kawai lists a weighted keyboard, two headphone sockets, speakers and line outputs on the ES120.
Trade-off: check that the controls make it easy to switch sounds and keys quickly for your rehearsals; connections and playing modes alone won’t tell you that.
| What to consider | What to look for when buying | Who should pay particular attention? |
|---|---|---|
| Quiet practice and audible playing | Check the headphone socket and whether you need speakers or suitable line outputs for rehearsals without headphones. | At home, I want to practise quietly and sometimes play audibly at rehearsals without a separate monitor; around 36% of consumers put this listening choice first. |
| Changes to key and sound | Try transposing and finding settings on the exact model; check that the sounds you want suit the way you rehearse. | When accompanying singers in different keys, I want to transpose quickly and find sounds easily; around 29% of consumers prioritise these changes. |
| Control over the piano part | Play the same soft and powerful passage on the model you’re considering, and try the pedal you’ll actually use. | When playing piano parts, I want to judge the touch for myself and make sure the pedal suits my playing; around 21% of consumers give this top priority. |
| Complete rehearsal setup | Compare the dimensions, weight, included accessories and sound equipment you’ll need in both playing locations. | When travelling between home and a rehearsal space, I want to know whether the instrument and the equipment I need will fit; around 14% of consumers prioritise transport and setup. |
The Korg D1 has no speakers, while Roland lists built-in speakers for the RD-08 and Yamaha for the CK88. Without headphones or external sound equipment, you can’t play a speakerless model audibly.
Decide in advance whether you’ll only play with headphones or also want to rehearse audibly without extra monitoring.
The Korg D1 may require suitable external speakers and connection cables.
According to Roland, certain controller functions and USB audio on the RD-08 require the separate RD-08 Upgrade.
Make a note of the recording or controller features you need and check whether they’re included with the version on offer.
The separate RD-08 Upgrade may be needed for these features.
The equipment you need varies depending on your setup. Korg lists a damper pedal as included with the D1, but no speakers; Kawai shows a stand and triple pedal unit as accessories for the ES120.
Check what’s in the box and which accessories you’ll need at home and in the rehearsal space.
Depending on your setup, you may also need a stand, pedal or external monitoring.
The RD-08 is a stage piano for players looking for direct controls, transposition and built-in speakers in one instrument.
The CK88 is a stage keyboard with piano, organ and synth sounds. The P-225 is a separate range of portable digital pianos for those who mainly practise piano.
The D1 is a speakerless stage piano for players who practise with headphones or already have external monitoring.
The ES120 is a portable digital piano for players who prioritise piano playing and flexible listening over dedicated stage controls.
Not automatically: if you’re the only one wearing headphones, the singer won’t hear the piano part through the speakers. First decide how you’ll both listen, then check what happens to the speakers on the exact model when you connect headphones. Roland lists connected headphones or an adapter as possible reasons why the RD-08’s speakers may not produce sound.
For personal listening, connect headphones. For audible playing, Korg recommends connecting the line outputs to suitable external sound equipment. Korg lists a power adapter and damper pedal as included, but no built-in speakers.
Don’t assume they are. Roland links selecting a USB driver for USB audio and certain controller functions to the separate RD-08 Upgrade. Before buying, check which features you need and which version is on offer.
