Roland has been a leader in digital piano technology for many years and is known for professional quality instruments. The company boasts to have introduced a new chapter of evolution in the world of digital piano keyboards with its latest HP series of SuperNATURAL Pianos. Today, we will review the HP 305 belonging to this series. In this series, Roland has made the magical combination of the elements of the revolutionary V Piano with the company’s own multi-sampling technology. Roland claims that its HP305 delivers a unique sound, expressivity, and even the rich playing experience of a traditional acoustic grand piano. Let us find out if we have a winner in our hands.

Roland HP-305 88-key Digital Piano


Roland has paid very close attention to the design elements of the HP-Series, co-ordinating cabinet details with simulated wood grain or matching colours, and also adds the ability to cover the control panel with the fallboard for a more traditional look. All of its elements have been made as compact as possible. The Classic Position and 3 pedals with traditional design make playing easier and enhance its piano-like appearance. The front legs provide a luxurious look, which are classically shaped. A centralised control panel with dedicated buttons assures easy and intuitive operation, by connecting two headphones, two players can practice independently at the same time. The HP305 Digital Piano is available in three spectacular finishes of polished ebony, satin black, and rosewood.

SuperNATURAL Piano Sound Engine:

The Roland HP 305 features the new SuperNATURAL Piano sound engine, which we had mentioned earlier. This engine combines Roland’s state of the art V Piano technology and its 88 key stereo multi-sampling technology. The new sound engine was developed after intense research on the different characteristics of acoustic pianos. The goal of the sound engine is to reproduce rich tones and expression of a concert grand piano.  The HP 305 provides 128 polyphony, which are more than sufficient for the complex pieces. Roland has tested all 88 notes of a variety of world class pianos and applied its unique digital technology to reproduce the rich tone and expression of the world’s finest pianos.

Ivory Feel keys:

The Ivory Feel keys on this piano replicate the natural appearance, texture, and the moisture absorbing properties of real ivory and ebony keys. The keyboard offers same feel as grand piano, heavier touch in lower range, lighter touch in upper range and light resistance on pianissimo passages and stronger resistance on fortissimo.


The Roland HP-305 88 key Digital piano Keyboard is equipped with a metronome and three-track recorder function, and can playback a variety of songs so you have all you need to support your progress. Playback your favourite built in songs with accompaniment, commercially available music files, and music CDs to make your practice more enjoyable. The HP 305 has been loaded with a library of play-along songs from jazz to classical.  You can store songs in HP 305 in variety of formats, which include SMF music files, files stored on USB flash memory, and audio CDs. You can select the parts in SMF file to play back. You can play an orchestra part in the playback and play a piano part to create a powerful performance. The tempo of the playback song can also be changed, the Centre Cancel function can be used to minimise the melody part in Audio CD, and the possibilities are endless.

Twin Mode:

To help the piano teachers, the HP 305 digital keyboard includes Twin Piano Mode, which splits the keyboard and pedals into two separate parts covering the same octaves. This allows the teacher to play along with their student, which highly speeds up the process of learning.


Roland technology also enables this piano to feature environmentally friendly, low-power consumption without sacrificing output level.

Roland HP-305 Digital Piano Keyboard


This breakthrough sound engine delivers seamless variations in tone, from pianissimo to fortissimo, decaying sounds which linger and fade naturally without any kind of looping. It also has an authentic sound transition from note to note across the digital piano keyboard. The natural touch of the Roland HP 305 digital piano keyboard comes from the use of hammer mechanisms that precisely reproduce the unique touch of an acoustic grand piano. It interacts with the SuperNATURAL Piano sound engine to mirror the subtleties while playing and hence, delivers finer rapid key strike expression.

Its special speaker system reproduces the sound generated by the Piano sound engine as a clear and spatial sound to allow players to give beautiful and smooth performances true only to the grand pianos. The piano tone is based on key range and touch with perfect smooth decay.  The tone change smoothly and naturally.


Roland offers its HP 305 Digital Piano Keyboard three years warranty.


The sound and touch of the Roland HP 305 Piano Keyboard is a result of persistent pursuit of characteristic of grand pianos. While the HP 305 is a mid market model, great attention has been paid to its sound quality, touch, and design. All the elements of HP 305 are made compact; the minimalistic and modern design of HP 305 makes it look like a true acoustic piano. Players can enjoy their performances to their hearts’ content on the PHA II Ivory Feel keyboard with escapement, which offers a natural texture and tactile feel. If at all there is anything such as a disadvantage with the Roland HP 305, it is its high end price tag. However, its amazing sound and performance justifies the bulky cost.
