Yamaha P225B vs Korg 88 Portable Digital Piano with Semi-Weighted Keys and Built-in Speakers

Key Action and Touch Feel

The Yamaha P225B features a Graded Hammer Compact (GHC) keyboard action with weighted keys, designed to replicate the authentic feel of an acoustic piano. This provides a more realistic playing experience, especially in the lower register where heavier keys mimic the increased resistance of real piano strings. In contrast, the Korg 88 has semi-weighted keys with Korg’s premium LS keyboard action, offering a lighter, faster response that’s better suited for players seeking agility over full weight simulation. The P225B’s design prioritizes authenticity, while the Korg 88 emphasizes portability and responsiveness.

Sound Quality and Piano Voices

The Yamaha P225B delivers the CFX Premium Grand Piano Voice, which captures the powerful tonal characteristics of Yamaha’s flagship concert grand piano. It also employs Virtual Resonance Modeling (VRM), which simulates how strings and the piano body resonate in real time, adding depth and realism to each note. The Korg 88 offers eight sounds including pianos, electric pianos, and strings, with particular emphasis on its “Italian Grand” piano sound, known for its rich, expressive tone. While both instruments provide high-quality digital piano voices, the P225B’s focus on acoustic replication through VRM gives it an edge in sonic authenticity.

Built-in Features and Connectivity

The Yamaha P225B includes a half-damper pedal for nuanced sustain control and integrates with the Smart Pianist app, allowing users to access advanced functions and expand capabilities beyond the instrument’s physical interface. The Korg 88 comes with built-in speakers, eliminating the need for external amplification at home, and supports USB Audio and MIDI connectivity for use with recording software and learning apps. It also includes a free three-month trial to Skoove Piano Learning software. The P225B relies on external app integration for expanded functionality, while the Korg 88 offers immediate access to learning tools and self-contained audio output.

Portability and Design

The Korg 88 stands out with its ultra-portable design, measuring only 2.87 inches thick and weighing just 13.23 pounds. It can run on six AA batteries for up to eight hours, making it ideal for travel or outdoor performances. The Yamaha P225B is not described as portable; instead, it focuses on compact space-saving design within a traditional upright format. While both are black in colour, the Korg 88’s thin profile and lightweight build make it significantly more mobile. For players who frequently move their instrument, the Korg 88’s design is clearly superior.

Included Accessories and Value

Both the Yamaha P225B and the Korg 88 come with a sustain pedal and power supply. The Korg 88 additionally includes a music stand and a built-in metronome, providing essential practice tools right out of the box. The P225B does not list these extras in its feature set, meaning users may need to purchase them separately. The Korg 88’s inclusion of a music stand and metronome adds tangible value, especially for beginners or casual users looking for a complete setup without additional costs.

Price and Market Positioning

The Yamaha P225B is priced at C$999.99, while the Korg 88 is available for C$549.99—about 45% cheaper. This significant price difference reflects the P225B’s focus on professional-grade touch and acoustic modeling, whereas the Korg 88 targets budget-conscious buyers seeking portability and versatility. The P225B holds a higher bestseller rank (13) compared to the Korg 88 (22), suggesting stronger market demand despite its higher cost. However, the Korg 88’s lower price point makes it accessible to a broader audience, particularly those new to digital pianos.

Which should you buy?

If you prioritize authentic acoustic piano feel, advanced sound modeling via VRM, and integration with smart technology through the Smart Pianist app, the Yamaha P225B is the clear choice—despite costing nearly C$450 more than the Korg 88. Its higher bestseller rank (13 vs. 22) underscores strong user confidence in its performance. However, if portability, affordability, and built-in features like speakers, a music stand, and a metronome are your top priorities, the Korg 88 offers exceptional value at C$549.99—about 45% less than the P225B. For players needing a lightweight, ready-to-use instrument for home practice or travel, the Korg 88 delivers more practicality per dollar. Choose the P225B for depth and realism; choose the Korg 88 for flexibility and cost efficiency.
