Product information

General

The Roland HP704 digital piano combines clean design and the meticulous playability of a PHA-50 keyboard, as well as the hyper-authentic sound of the Roland-developed SuperNATURAL sound engine. The three pedals provide all of the expression, dynamics and the fluid feel of an acoustic upright piano, and when compared the smaller the HP702, the Roland HP704 comes with a more refined keyboard and an expanded sound system.

The Roland HP704 Digital Piano: Acoustic Projection

The four-way speaker system has been divided into two pairs and comes backed up by the in-house designed Acoustic Projection, which expertly reproduces the lower and higher registers with the same tonality and character as that of an acoustic piano. The headphone output operates with the same system so that, whether silently rehearsing with headphones or performing using the speaker system, you get the same faithful level of acoustic emulation.

Bluetooth Pairing & Other Connections

Play along with music by pairing a Bluetooth device or by hooking up an external audio player via the aux-input and playing tracks back using the built-in speakers. The Bluetooth connection is also useful when following online tutorials but really gets interesting when coupled with the various teaching apps available directly from Roland, including Piano Every Day. If you want a little more volume than the on board speakers will allow, a line output is fitted for direct connection to a mixer or amplifier. And, to make recordings or playback MIDI and audio files, just slot your USB stick into the USB Memory port or connect it directly to your computer and use the HP704 as a MIDI controller for virtual instruments.

For the Parents

In designing the HP704, Roland have spared a lot of thought for the parents whose children will be moulding their craft on this instrument. As such, the volume of both the headphone output and speakers of this digital piano can be set at a specific limit while the opening and closing of the piano lid has been cleverly connected to the on/off switch. Also, the TwinPiano function can be activated to split the keyboard into two halves, each with a different sound, to make practising exercises a little more fun, while specially developed Roland apps enable study, not just by teaching demo songs, but also an understanding of the sheet music as the songs are played.
