Keyboard Action & Feel

One of the most important factors when choosing a digital piano is keyboard action and feel. A good digital piano should replicate the touch, weight, and response of an acoustic piano as closely as possible, allowing for a realistic and expressive playing experience.

The Yamaha YDP-105 and Kawai KDP120 both feature fully-weighted, hammer-action keyboards, but their action mechanisms are quite different. Let’s explore the technology, responsiveness, realism, and playability of each in detail.

Understanding Hammer Action in Digital Pianos

Before diving into the specifics of each model, let’s briefly cover what hammer action means in digital pianos.

Acoustic pianos rely on hammers striking strings to produce sound. In digital pianos, manufacturers use graded hammer action to mimic this weighted response, meaning:

• Lower keys (bass notes) feel heavier,
• Higher keys (treble notes) feel lighter,
• The action is designed to replicate the mechanical feel of an acoustic grand piano.

However, not all hammer actions are created equal. The quality of the action depends on factors like:
✔ Key weight & resistance (Does it feel too light or too heavy?)
✔ Escapement/simulated let-off (Does it feel like a grand piano?)
✔ Key material & texture (Plastic vs. synthetic ivory/ebony)
✔ Overall responsiveness (Can you play fast passages easily?)

Let’s see how the Yamaha YDP-105 and Kawai KDP120 stack up.

Yamaha YDP-105 – Graded Hammer Standard (GHS) Action

The YDP-105 uses Yamaha’s Graded Hammer Standard (GHS) action, which is Yamaha’s most basic fully-weighted action. It is the same action found in many of Yamaha’s entry-level digital pianos, such as the P-45, P-125, and YDP-144.

Pros of the GHS Action

✅ Graded Weighting: The keys are heavier in the lower register and lighter in the higher register, mimicking an acoustic piano.
✅ Reliable & Well-Tested: Yamaha’s GHS action has been around for years and is known for being consistent and durable.
✅ Good for Beginners: The action is light enough for beginners to play comfortably without too much strain.

Cons of the GHS Action

❌ Lighter & Less Realistic Feel: Compared to an acoustic piano, the GHS action feels lighter and slightly springy, lacking the resistance and depth of higher-end actions.
❌ No Escapement Simulation: Acoustic grand pianos have a let-off (escapement) mechanism that gives a slight resistance when playing soft notes. GHS does not replicate this, making it feel less like a real grand piano.
❌ Plastic Keytops: The keys are glossy plastic, which can feel a bit slippery after extended playing. Higher-end models have textured, synthetic ivory/ebony key surfaces that offer better grip.
❌ Limited Expressiveness for Advanced Players: Fast repetitions and subtle dynamic control can feel slightly unnatural compared to higher-quality actions.

🔹 Overall Impression of Yamaha’s GHS Action:
The GHS action is decent for beginners and intermediate players but lacks the depth and realism needed for advanced pianists. The lightness of the keys makes it easy to play, but it does not replicate the resistance and nuanced control of an acoustic piano.

Kawai KDP120 – Responsive Hammer Compact II (RHCII) Action

The Kawai KDP120 uses the Responsive Hammer Compact II (RHCII) action, which is a step up from Yamaha’s GHS in terms of realism and responsiveness.

Kawai is known for its exceptional acoustic pianos, and their digital pianos reflect this expertise by using more advanced keyboard actions than most competitors in this price range.

Pros of the RHCII Action

✅ More Realistic Weighting: Compared to Yamaha’s GHS action, the RHCII action feels heavier and more substantial, providing a closer experience to an acoustic piano.
✅ Escapement (Let-Off) Simulation: Unlike the YDP-105, the KDP120 features escapement simulation, meaning you feel a slight notch when pressing the keys lightly—just like on a grand piano.
✅ More Dynamic Control: The key movement feels smoother and more responsive, allowing for better expression in soft and loud passages.
✅ Textured Key Surfaces: The KDP120’s keys have a matte texture, making them less slippery than Yamaha’s glossy plastic keys.
✅ Quiet Key Action: The keys on the KDP120 produce less noise when pressed and released, making it quieter to play in home environments.

Cons of the RHCII Action

❌ Heavier Key Feel: Some beginners might find the RHCII action heavier than Yamaha’s GHS, making it slightly harder to play for long periods. However, this can be a good thing for those who want to build finger strength.
❌ Still Not as Realistic as Higher-End Actions: While better than Yamaha’s GHS, it doesn’t match the realism of Kawai’s higher-end Grand Feel actions found in more expensive models.

🔹 Overall Impression of Kawai’s RHCII Action:
The RHCII action is clearly superior to Yamaha’s GHS. It feels more substantial, expressive, and realistic, making it a better option for pianists who want a closer-to-acoustic feel.

One of the most crucial aspects of any digital piano is sound quality. A digital piano’s sound is what truly defines the playing experience, influencing how expressive and enjoyable it feels to perform on.

The Yamaha YDP-105 and Kawai KDP120 both feature high-quality piano samples, but there are significant differences in how they generate sound, the realism of their tone, and the overall listening experience. In this section, we’ll take a deep dive into their sound engines, polyphony, resonance effects, sound customization options, and real-world performance to determine which model offers the best sound quality.

Understanding Digital Piano Sound Technology

Unlike acoustic pianos, which generate sound by hammers striking strings, digital pianos use pre-recorded samples of real acoustic pianos or modeled synthesis to create sound. Several factors influence how “realistic” a digital piano sounds:

1. The Quality of the Sampled Piano – Which acoustic piano was used to create the digital sound?
2. Sample Depth & Layering – Are multiple samples recorded for different playing dynamics (soft, medium, hard), or is it just a basic recording?
3. Resonance Effects – Does the digital piano simulate important acoustic properties like string resonance, damper resonance, and key-off sounds?
4. Polyphony Count – How many notes can sound at once before notes start cutting off?
5. Speakers & Amplification – A great piano sample can still sound weak if the speaker system isn’t powerful enough.

Now, let’s compare how the Yamaha YDP-105 and Kawai KDP120 perform in these areas.

Sound Engine: AWM Sampling vs. Progressive Harmonic Imaging (PHI)

Yamaha YDP-105 – AWM Stereo Sampling

• No string resonance or damper resonance simulation, making it feel more like a basic digital keyboard rather than a true acoustic piano.
• The decay of notes is shorter, meaning sustained notes don’t ring out as naturally as they would on a real piano.

👉 Overall, the AWM engine delivers a decent but somewhat artificial sound, making the YDP-105 feel more like an entry-level digital piano rather than a true acoustic replacement.

Kawai KDP120 – Progressive Harmonic Imaging (PHI)

Kawai uses Progressive Harmonic Imaging (PHI) technology, which is a more advanced and expressive sampling engine compared to Yamaha’s AWM.

✔ What’s good about it?

• The piano sound is sampled from the Shigeru Kawai SK-EX concert grand piano, one of the most renowned acoustic pianos in the world.
• The sound is richer, more dynamic, and more natural-sounding compared to Yamaha’s AWM sampling.
• Multi-layered sampling technology ensures that the piano responds more realistically to different playing dynamics—soft notes sound delicate, while hard strikes sound bold.
• Includes damper resonance simulation, which recreates the natural interaction of strings inside an acoustic piano.
• The longer sustain and natural decay of notes make it feel more immersive and realistic.

❌ What are its limitations?

• While better than Yamaha’s AWM, PHI is still a sample-based engine rather than full-fledged physical modeling, meaning it doesn’t have infinite sound variations like high-end pianos with full modeling technology.
• Some players might find Kawai’s warmer tone a bit too mellow, especially if they prefer a brighter and more cutting sound like Yamaha’s CFIIIS samples.

👉 Overall, the KDP120’s PHI engine is significantly more advanced than the YDP-105’s AWM engine, providing a more detailed, dynamic, and expressive playing experience.

Polyphony: 64 vs. 192 Notes
