“What is Roland Pure Acoustic Modelling Technology?“

Has The Digital Piano Come of Age?

15 to 20 years ago, traditional acoustic pianos were often considered the only choice for serious players. “Electric pianos” as they were called at the time though, were vastly different from digital piano technology we have today.

Even though times have changed, many experienced players still think digital pianos lack the level of detail and involvement that a more expensive acoustic instrument can provide.

The Instrument and You

There’s an important connection that happens between the player and the instrument.

There’s a certain feeling you get when you sit down at a premium upright piano. Perhaps it’s the fact that the appearance hasn’t changed much for the last 70 to 80 years so there’s a timelessness to it. You instantly soak up all the creative heritage before you’ve even played a note.

And when you do strike the keys, there’s a cascading series of events that occur starting with the hammers to the strings, then to the bridge, the soundboard, through to the cabinet and back to the player. It’s an incredible connection that it is both musical and physical at the same time.

Achieving a similar level of connection was of the utmost importance when designing our premium LX700 Series pianos.

In this article we’ll look at why our advanced piano technology will allow you to express your creativity to the fullest.

Piano Sound & Behaviour

At the heart of the Roland LX700 series is the incredible Pure Acoustic modelling engine. This state-of-the-art technology is what allows these pianos to actually “behave” like a professional acoustic piano. It’s not just how good the sound is, it’s how it evolves, how it creates emotion when you play, how it inspires creativity in the player.

Watch as Australian jazz icon James Morrison talks about his experience with the Roland LX700 series:

There are a multitude of physical interactions that occur on an acoustic piano such as keys being pressed, hammers striking strings, strings resonating, the cabinet resonating, what notes you play and where, even how much pedal you are using. All these interactions in an acoustic piano combine to communicate exactly what the piano is doing to the player. 

The Pure Acoustic modelling engine uses two powerful Behavioural Modelling Cores to achieve a similar deep level of communication between the piano and the player.

Progressive Hammer Action KeysAnother key attribute of a quality piano is the key action. Having a mechanism that allows for fine control, fast repetition, and an intimate connection to the way the sound is produced is essential.

The PHA-50 Key action in the LX705 and PHA-100 Hybrid Grand action on the LX706 and LX708 both feel natural and expressive to play. With wooden inserts, synthetic ivory key-tops and an extremely durable inner frame, these actions will provide years of maintenance free service whilst providing serious pianists with exactly what they need to perform at the highest level.

Sensational Speaker Systems

With such great sound and feel, it’s also important just how this sound is projected. Each LX700 model includes an Acoustic Projection System, reproducing the rich, room-filling sound of a grand piano in a great venue – without needing the floorspace.


The flagship LX708 houses a four-way, eight-speaker system, driven by a powerful amplifier, with each speaker fulfilling a specific role in delivering superior piano tone. The cabinet speakers produce the all-enveloping main sound, while the top-mounted spatial speakers reproduce the resonance of the piano’s frame, projecting through the front C-shape wide aperture. Finally, the nearfield speakers and tweeters project the sounds you’re most likely to notice, including dramatic, dynamic overtones and even the noise of the hammers hitting the strings through the keyboard section.

Roland engineers designed these speaker systems to work hand in hand with the Pure Acoustic modelling engine to create an incredibly immersive piano experience as a professional series acoustic piano would.
