Key Specifications

The P115B features 88 weighted keys with Yamaha’s GHS (Graded Hammer Standard) technology. This means the keys feel heavier in the lower end and lighter in the higher end, just like a real piano.

I’m impressed by the 192-note polyphony, which allows for rich, layered playing without notes cutting out. The CF Sound Engine recreates the tone of Yamaha’s famous CF III concert grand piano.

The piano includes 10 different voices and various rhythm patterns. You can adjust the key sensitivity to match your playing style, which I find incredibly helpful.

Connectivity options include:

• USB to HOST port for computer connection
• AUX OUT jack for external speakers
• Headphone jack for private practice

The piano weighs about 26 pounds and measures 52 inches wide. Two 7-watt speakers provide clear sound for room-level playing.

What’s Included in the Box

When you purchase the P115B, you’ll receive the main piano unit and a sustain pedal. The sustain pedal is essential for authentic piano expression and comes standard with your purchase.

I should mention that you’ll need to purchase a stand separately if you want one. The piano works great on a table or desk, but a proper stand makes playing more comfortable.

The package also includes a power adapter and music rest. Some retailers may include additional accessories, but these vary by seller.

You won’t find a bench included, so plan to purchase one separately. The piano is compatible with most standard keyboard stands and benches.

Who Is the Yamaha P115B For?

I believe this digital piano works well for beginning students who want to develop proper finger technique. The weighted keys help new players build the muscle memory they’ll need for acoustic pianos.

Intermediate players will appreciate the authentic sound and touch response. The adjustable key sensitivity lets you customize the feel to match your playing style.

The piano also serves gigging musicians well thanks to its portability and professional sound quality. At 26 pounds, it’s manageable for transport to performances or rehearsals.

Home players who want a quality instrument without taking up much space will find this appealing. The compact design fits in most rooms while still providing a full 88-key experience.

Budget-conscious buyers get excellent value around $600. You’re getting Yamaha quality and features that compete with more expensive digital pianos.

The P115B delivers impressive sound through Yamaha’s Pure CF Sound Engine and samples from their premium concert grand piano. With 192-note polyphony and solid amplification, it produces rich, realistic piano tones.

CF Sound Engine Explained

I’ve found the Pure CF Sound Engine to be the heart of what makes the P115B sound so authentic. This technology reproduces the tone of Yamaha’s meticulously sampled acoustic pianos with remarkable accuracy.

The engine captures multiple layers of sound for each key press. This means when I play softly or forcefully, the piano responds with different tonal qualities just like a real acoustic instrument.

What impressed me most is how the CF Sound Engine handles the subtle details. The resonance between strings, the hammer strike variations, and even the ambient room sound are all recreated digitally.

The engine also manages the transition between different velocity levels smoothly. I never hear abrupt jumps in tone when I vary my playing dynamics.

Sampling from the CF III Concert Grand Piano

The P115B uses samples recorded from Yamaha’s acclaimed 9-foot CFIIIS concert grand piano. This isn’t just any piano — it’s the same model used in major concert halls worldwide.

Each note was recorded at multiple volume levels to capture the full range of expression.

When I play quietly, I hear the gentle hammer touch, and when I play loudly, the full power of the concert grand comes through.

The sampling process captured not just the initial attack of each note but also the sustain and decay. This means the notes ring out naturally and fade just like they would on the original instrument.

I can really hear the difference this makes compared to cheaper digital pianos. The tone has depth and character that makes practicing feel more inspiring.

Polyphony and Number of Voices

The P115B offers 192-note polyphony, which is a significant upgrade from earlier models that had 128 notes. This higher polyphony count means I can play complex pieces without notes cutting off unexpectedly.

In practical terms, this polyphony handles even the most demanding classical pieces with ease. When I use the sustain pedal heavily or play dense chords, every note rings through clearly.

The piano includes 10 different voices beyond the main grand piano sound. These include electric pianos, organs, and string sounds that add versatility to my playing.
