Enjoy the Sophisticated Sound of an Authentic Grand with SuperNATURAL Piano
Every time you sit down and play the HP504, you’ll lose yourself in a beautiful and immersive piano experience, thanks to Roland’s acclaimed SuperNATURAL Piano sound engine. Just like a fine acoustic grand, each note has its own character, and the tonal color changes seamlessly in response to your touch to accurately translate your emotions into sound. Tone decay is natural and organic, with the sound not only decreasing in volume, but also gradually changing in color to a softer tone. In addition to authentic grand piano tones, upright piano tones are now included as well, which provide the unique short decay and up-close sound of a traditional upright instrument.
Explore an Expanded Range of Dynamic Expression
As you refine your piano skills, your ability to play with a strong touch will improve, and the unique overtone characteristics created with fortissimo playing will provide a new palette of tonal colors for you to explore. The newly developed Dynamic Harmonic feature allows you to adjust these characteristics to your taste, offering a deep level of expressive control that will be welcomed by more experienced players as well.
Customize the Sound to Suit Your Playing Style or Living Space
It’s easy to modify the HP504’s sound for your personal playing style or a specific musical genre. With the onboard Piano Designer, you can adjust overall tonal elements such as string resonance, soundboard behavior, and many others. For even more detailed customization, the newly developed Individual Note Voicing feature lets you adjust the pitch, level, and tonal character independently for all 88 notes. In addition to personal tone shaping, this unique and powerful voicing option is also useful for balancing the overall piano sound to perfectly suit the acoustic properties of any room or the response of a particular set of headphones.
Premium Keyboard Touch with Ivory Feel
As your expressive skills develop, your piano performances will shine on the HP504. The new PHA-4 Premium Keyboard with Escapement and Ivory Feel includes Roland’s latest touch-detection technology, allowing you to derive the full tonal potential of the SuperNATURAL Piano sound engine. With fast key repetition and high-resolution sensing, the PHA-4 faithfully translates into sound the subtlest differences in tone from different playing styles and dynamics. In addition, the white keys are finished with material that has moisture-absorbing properties, providing the natural texture and tactile sensation of real ivory. The PHA-4’s authentic hammer-action mechanism also produces less audible noise than previous designs, a welcome feature for not disturbing others when playing with the speakers muted during practice sessions with headphones.
Authentic Damper Pedal Response
Equipped with a Progressive Damper Action pedal, the HP504 accurately replicates the true damper pedal behavior of an acoustic piano. It features the continuous tactile response that experienced players expect, with light resistance when the pedal is first pressed and more resistance as the damper function begins to take effect. This allows for more intuitive control while playing, and makes it possible to execute advanced “half-pedal” techniques that provide subtle degrees of control over sustain and resonance.
3D Sound Space for More Enjoyable Practice with Headphones
If you practice at night or when others are nearby, you’ll likely be listening to the HP504 through headphones for long periods of time. With the newly developed Headphones 3D Ambience effect, you can now enjoy the unique sound field of an acoustic piano during these private sessions. This innovative technology greatly enriches the piano experience when playing with headphones, making it feel as though the sound is emanating from the instrument itself.
Build Skills Quickly by Recording and Evaluating Your Performances
A great way to make daily practice more efficient is by recording and listening back to your playing for self-evaluation and improvement. The HP504’s built-in recorder is always at the ready, letting you capture your performances as MIDI data onboard the piano or as audio data to optional USB flash memory. To share your audio performances with your family, friends, or teacher, simply connect the USB flash memory to your computer and transfer the files, and then upload them to your favorite sharing services or social media sites. Instant recording is a powerful feature not only for students, but for experienced pianists as well.
Piano Partner and Air Performer Apps Help Develop Your Skills and Make Practice Fun
Roland’s free apps for Apple iOS devices offer a unique and fun way to motivate your interest in playing and practice. With Air Performer, you can play along with favorite songs in the iPhone, iPad, or iPod touch wirelessly* through the HP504’s sound system. The Piano Partner app for iPad includes Flash Card, an interactive music program that kids will love, plus an intuitive graphical interface for exploring tones and songs in the HP504. Available from the Apple App Store, these powerful apps make it easy to use today’s mobile technology to enhance your piano development.
*Wireless communication requires the Wireless USB Adaptor (Roland WNA1100-RL or ONKYO UWF-1) and a wireless LAN access point with an Internet connection.
Convenient Extra Features for Everyday Playing
The HP504 includes numerous practical features to support daily piano use. With the Volume Limit function, you can preset a maximum level for the piano’s volume control so your kids can’t play loud sounds unexpectedly. The headphones volume can also be adjusted separately from the speaker volume, which helps prevent unintended loud sounds from being output through the headphones when they’re plugged in. And with both stereo 1/4-inch and stereo 1/8-inch miniature headphone jacks, you can connect either standard over-ear headphones or the small earphones that are popular with music players and mobile devices. The HP504’s built-in music rest is easily adjustable for anyone that plays the piano, allowing you to set the ideal angle to match the sitting height of everyone from small children to adults.
