Roland HP504 Upright Digital Piano—Under the Lid

SuperNATURAL sound and an expanded range of dynamic expression

Roland’s acclaimed SuperNATURAL Piano modeling engine gives you the ability to lose yourself in a beautiful and immersive pianistic experience. Just like a fine acoustic grand, each note has a unique character based on the overtone series. And just as you would expect from a fine acoustic piano, the tonal color changes seamlessly in response to your touch, accurately translating your emotional expression into sound. Each note’s envelope 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.

Dynamic Harmonic feature lets your playing evolve naturally

Since piano playing results in an evolving physical acquisition over time, your ability to play with a strong touch will improve. While a keyboard with a fixed or limited touch will prevent you from developing naturally, Roland’s Dynamic Harmonic feature 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

Wouldn’t it be great if you could change the sound of your acoustic piano to something more suited to your style and preferred genre of music? Well, you can’t, unless you’re independently wealthy. However, with the HP504, it’s easy to modify sound for your 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.

The Great Escapement

When we say that a digital keyboard can satisfy both amateur and professional, we’re not just talking about sound quality. As any classical pianist will tell you, escapement, s an essential feature that without it, would disqualify a digital piano as an option.

Escapement, also known as “let-off,” is what allows the hammer to be released (escape) after it strikes the string, even if the key is still depressed. Without this “single escapement,” the hammer would be held against the string (muting its vibrations) for as long as the key was depressed. What’s unique about the escapement is the feel it has when you press a key. It has a specific “clicking” feel when a key is depressed about halfway down, which is an integral characteristic of acoustic piano action.

The escapement action and clicking feel, typically found only on high-end digital pianos, is a feature found all Roland digital pianos, regardless of price point, which makes the HP504 that much more of an incredible value—and enables experienced pianists to seamlessly transition from acoustic to Roland digital pianos, and conversely, students who learned on digital pianos to play acoustic pianos without having to alter their technique.

Continuous detection 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.

Practice with headphones in three-dimensional space

If you practice at night or when others are nearby, you’ll likely be listening to the HP504 through headphones for long periods. 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.

Record and evaluate your progress

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.

Develop your skills and make practice fun with Piano Partner and Air Performer apps

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

Every-day convenience and practical features

Once of Young Wolfgang Mozart’s favorite pranks when his father Leopold wasn’t teaching in the Archbishop of Salzburg’s conservatory and resting peacefully at home, was to play a series of unresolved 7th chords and run out of the house. This would disturb Leopold’s delicate sensibilities to the point where he would drag himself to the piano to play the resolving tonic chord.

You kids may not come up with such an elegant torture, but 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.

The Roland DP504 presents an affordable means to bring evocative piano performance and musical enjoyment into your home. For more information, call or chat online with a Hollywood Piano specialist.
