Product Description

Overview

The all-new Roland GP-6 is a digital baby grand equipped with the newest generation of sound reproduction technology, as well as a wood-hybrid digital key action which closely mimic’s the touch and weight of a real acoustic baby grand (Piano Reality Premium Keyboard Action).  It’s cabinet is built using the same materials that real pianos use, and the overall fit and finish of the entire build suggests an expected lifespan of well over 10+ years. 

The GP-6 features a multitude of new innovations which bring its level of musical authenticity to an unmatched level for it’s category and price. The sound engine is a completely re-invented computer model which generates tone in real time based on a players every input and nuance (Piano Reality Premium Tone Engine). An enhanced stereo image the player now has at the keyboard is enhanced both by an all-new tone engine algorithm with multi-channel output, but also a new set of front-facing tweeters which actively resonate the front panels of the piano, creating a truly authentic sense of cabinet resonance.

And finally, the GP-6 is highly versatile, able to satisfy the hard-hitting percussive rhythms of rock, blues, or jazz players with tons of power and a clear bass, while at the same time delivering a delicacy and nuance through the lower dynamic ranges that will surprise even the harshest digital piano critics.

Piano Action

Roland has completely overhauled their actions and tone engines right across the entire company, and starting with these GP models. What used to be known as the PHA-50 is now known as the Piano Reality Premium Keyboard Action. But it’s more than just a re-branded PHA-50. The sensors have been accelerated and the cushioning improved. When playing the new action and trying to pay attention to these improvements, the changes seem subtle. But then again, the difference between a truly connective action and one that simply feels lifeless is entirely in those subtle changes.

The other features that made the PHA-50 such a remarkable action continue on into the new Piano Reality Premium, such as the stabilizer pin, the lengthened key sticks, the partial wood core, and the acoustic-like black and white key surfaces.

All in all, an action that, in combination with the new touch curves and sound tech, probably delivers the most ‘acoustic’ experience behind a Roland digital piano to date.

Sound Engine

The GP-6 is powered by a series of digital amplifiers – that is the amplified signal is created digitally, vs the signal being converted to analog earlier in the chain. This has led to a cleaner, much higher fidelity of tone, particularly in the higher frequencies and transients. Those amplifiers are driving 5 speakers – one downward facing 25cm woofer for the low frequencies, two upward facing 12cm for the majority of the upper mids, and two 5cm tweeters that are within the cabinet to generate true acoustic resonance and increase the sense of sound stage from the player’s perspective. 

Driving that new amp/speaker configuration is a new generation of sound engine based off Roland’s SuperNATURAL Modelling engine (for the acoustic piano tones) called Piano Reality Premium Modeling Tone Engine. The modelling algorithm is updated, based off of a new sample set, and they’ve incorporated multi-channel output into the output as well. So rather than have several speakers fed essentially by stereo output and balanced with cross-overs and various filters, it’s baked directly into the processing. And finally, the touch curve has been re-done to better interpret sensor data in the mid to upper-mid velocity ranges. The result? A truly responsive and much expanded mezzo forte to fortissimo range (a portion of the dynamic output on past Rolands that have tended to be a little compressed).

Move past the acoustic piano sounds and you’re into more conventional sample-based playback with 256 max polyphony.  More than adequate for virtually any type of playing or layering.

Connectivity

The GP-6 supports virtually all the connectivity options that customers typically expect: 

• USB connectivity with both A and B ports; 
• ¼” outputs for PA and home stereo integration; 
• Bluetooth Audio and Midi; 
• Dual headphone outs
• DC In jack for the power adapter

While there’s nothing particularly remarkable in the port offering here, it’s everything you’d expect and need. The piano connects with the Roland Piano App as well as any other Midi-enabled software out there – wireless for mobile, wired for desktop. 

Notable Features

Real Polyester: Roland, like Kawai, uses real Polyester epoxy resin for its outer finish. This in itself is a significant reason for the high cost of these GP cabinets, as digital pianos typically use a high-gloss vinyl wrap sprayed with a urethane clearcoat. The durability (and repairability) of the polyester is substantially better, and for over 50 years, has been the standard high-gloss finish in the acoustic piano world.

Dual-position lid: The adjustable lid position (mid and full) with two prop sticks isn’t merely an aesthetic feature – it appropriately simulates the tonal change in real grand pianos when lids are closed, partly open, or fully open. The sticks are substantial and locks into place with certainty so that pets or younger children won’t easily knock them and cause the lid to collapse (a genuine risk with most digital baby grands due to how light the lids are)

394 Internal Songs: While many digital pianos offer a few dozen internal ‘demo’ songs, to have nearly 400 on hand without any need for external sources or troublesome USB imports means the piano can be used for entertaining right out of the box with literal hours of piano music.

Buttonless Interface: Roland has gone with a ‘hidden’ interface which can be made to disappear even when being used, giving the player and audience members the impression that it’s a button-less, ultra-sleek instrument devoid of unsightly dials and displays. Even when activated, they’ve carried a lot of design language over from the newer LX and FP60x / 90x models, and tastefully so. 

Conclusions

From a purely rational standpoint, the GP-6 is one of the rare digital grand pianos that can be justified on multiple fronts. Its price finds a middle ground that’s close enough to console digital pianos of a similar technology spec that this won’t feel like an extravagance for buyers who equally prioritize looks vs performance. But musically speaking, the GP-6 stands strongly on its own by any measure and without the need for qualification or asterisks. The use of real cabinet resonance, improved audio signal delivery to the speakers, and a revamped tone algorithm deliver the most acoustic and responsive piano experience I’ve had thus far on a Roland piano
