Korg Grandstage Review: The Ultimate Performance Keyboard

As a professional keyboardist and pianist, I’m always on the lookout for the next great stage piano. I’ve played everything from Nord to Roland to Yamaha over the years, but when Korg announced their new Grandstage keyboard, I knew I had to get my hands on one. After extensive testing and gigging with the Grandstage 88 for the past few months, I’m ready to share my in-depth review.

Unboxing and First Impressions

When the Grandstage arrived on my doorstep, I’ll admit I didn’t have huge expectations. The minimalist design and lack of flashy features made me think this would be a pretty basic keyboard. However, as soon as I opened the box and set it up, the high build quality was apparent. Weighing in at just under 50 pounds, the Grandstage has a sturdy, metal construction that feels like it could withstand years on the road.

The 88-key version I purchased features Korg’s RH3 keybed – the same one found in their popular SV-2 stage piano. The weighted hammer action is reminiscent of an acoustic grand, with a bit more resistance in the lower keys and a lighter touch up top. It’s not quite as realistic as the Kawai action in the MP11SE or the escapement in Nord Pianos, but overall the Grandstage provides a very playable and dynamic keyboard feel.

Korg is known for its high-quality instruments, and the Grandstage is no exception. It is built with premium materials and features a sturdy and durable construction, ensuring long-lasting performance and reliability. The keybed, in particular, utilizes Korg’s RH3 technology, which provides a responsive and realistic playing experience. The build quality of the Grandstage is a testament to Korg’s commitment to excellence and is on par with other top-tier digital pianos on the market.

Sound Quality

Don’t let the simple interface fool you – the Grandstage is packed with features under the hood. Powered by the same EDS sound engine as Korg’s flagship Kronos, the Grandstage contains a whopping 500 different sounds ranging from piano and electric piano to strings, organ, synth leads, basses, and more.

The piano sounds are the highlight here, with meticulously sampled German and Japanese concert grand pianos. The attention to detail is incredible, capturing the unique resonance and character of the real instruments. Subtle mechanical noises, pedal noises, and intricate release samples make these some of the most realistic piano sounds I’ve heard in a stage piano.

Overview of the Korg Grandstage’s Sound Technology

The Korg Grandstage features a combination of multiple sound engines to create a rich and authentic audio experience. It utilizes Korg’s SGX-2 acoustic piano sound engine, which reproduces the natural resonance and expressive nuances of an acoustic piano. Additionally, the Grandstage incorporates the EP-1 electric piano sound engine and the AL-1 analog modeling engine for an extensive range of classic and modern instrument sounds.

Evaluation of the Sound Quality and Tone

The sound quality of the Korg Grandstage is exceptional, with the multiple sound engines working together to produce a rich and authentic tone. The acoustic piano sounds are detailed and dynamic, capturing the subtle nuances of an acoustic piano. The electric piano and other instrument voices are equally impressive, offering a wide variety of timbres and expression for various musical styles. Overall, the Korg Grandstage’s sound quality and tone stand out among its competitors.

Key Action and Playing Experience

The keyboard of the Korg Grandstage features weighted keys that provide a realistic playing experience. The key action is responsive and dynamic, allowing for expressive performances with excellent control over dynamics. Overall, the playing experience on the Grandstage is top-notch, rivaling that of high-end digital pianos like the Yamaha P-125 and the Roland FP-60X.

Gone are the days of plonky, unresponsive keys when you’re playing the piano. The Korg Grandstage 88 is equipped with RH3 “weighted hammer action,” which feels just like a real acoustic grand piano. But get this – the weight isn’t actually in each key! Instead, it’s distributed across multiple mechanical points on the keyboard to balance out its feel and responsiveness so even heavy-handed musicians can now enjoy natural-sounding notes without breaking anything.

The key action of the Korg Grandstage is responsive and dynamic, thanks to its RH3 keybed. This technology simulates the graded hammer action found in acoustic pianos, with heavier key resistance in the lower register and lighter resistance in the higher register. This feature allows for expressive and nuanced performances, closely resembling the feel of a traditional piano.

Evaluation of the Playing Experience

The playing experience on the Korg Grandstage is exceptional. The combination of the realistic key action, high-quality sound, and versatile features makes for a deeply engaging and enjoyable playing experience. Players can expect excellent control over dynamics and expression, making it a suitable choice for various music genres and performance settings.


On the front panel, you get hands-on control over the most important parameters using dedicated knobs and buttons. I love the “dynamics” knob which adds a volume boost for solos, as well as the simple EQ section. Effects like reverb, delay, chorus, phaser, and amp simulation can be quickly tweaked and tailored to your needs.

Two assignable switches give you the flexibility to control different functions like sustain, rotary speed, or effects on/off. You can instantly swap sounds between the upper and lower sections of the keyboard at the touch of a button. Everything is laid out logically and designed for real-time sound shaping on stage.

The Korg Grandstage is packed with features to enhance the playing experience, such as:

  • Multiple sound engines for realistic and expressive sounds
  • A wide selection of high-quality instrument voices
  • Layer and split modes for combining sounds and creating custom patches

The Grandstage is compatible with most popular DAWs, such as Ableton Live, Logic Pro, and FL Studio, allowing musicians to use the Grandstage as a master keyboard/controller for their music production setup.

Gigging with the Grandstage

After getting familiar with the Grandstage at home, it was time to take it out for some gigs. For most shows, I stuck with the piano sounds and used the keyboard in a simple, single zone setup. The German Grand piano became my new go-to – it’s rich, bold, and cuts through a mix nicely with the dynamics knob boosted. I’m able to go from delicate, emotive passages to pounding rock solos, all from the same preset.

The EPs also performed great live, especially the ’73 Fender Rhodes and Wurlitzer 200A. I like being able to quickly add phaser or chorus with the assignable switches for some extra vibe. The amp simulator does a decent job emulating the warm overdriven tone of a real Rhodes suitcase amp.

When I needed more complex setups, the Grandstage delivered. I made a split with bass and pads in the lower section and piano up top. The pads sounded full and lush, complementing the piano nicely without getting in the way. I also made good use of the layering, stacking string pads under grand piano to make it sing. The seamless sound switching ensured no hiccups or audio dropout when changing sounds mid-song.

All in all, the Grandstage proved to be a stellar live keyboard. The sound quality and keyboard action rival that of my Nord Stage 3 – which is 3 times the price! The intuitive interface also makes it much easier to dial in sounds on the fly compared to the menu-diving required on some other boards.

Recording with the Grandstage

In addition to live playing, I use my stage piano as the master keyboard for recording in my home studio. The Grandstage integrates flawlessly thanks to the 5-pin MIDI I/O and USB connection. I’m able to play the Grandstage while controlling VSTs on my DAW for the ultimate piano/plugin hybrid setup.

The onboard sounds also work great for tracking. I’m constantly inspired by the nuanced details in the piano samples while recording. Electric pianos like the ’64 EP and ’73 Rhodes capture the real vibe of the instruments with lots of personality and attitude.

For virtual instruments, the Grandstage’s keyboard action gives me the responsive, dynamic feel I want while inputting MIDI notes. The 3 pedal inputs allow me to control sustain, sostenuto, and soft pedal for detailed piano performances. Overall it’s a perfect do-it-all solution for my studio needs.

Review and Score

Our Score: 77/100

The Korg Grandstage has cemented itself as my new #1 stage piano – it’s the best bang for buck keyboard I’ve ever played. The sound quality rivals that of instruments costing 2 or 3 times as much. For gigging and recording, it provides everything I need and nothing I don’t.

The streamlined interface does mean you lose some bells & whistles like complex menus, screens, and drawbars. However, I actually prefer having a simple, focused panel with quick access to essential controls. For live playing, less is often more.

At its core, the Grandstage delivers pro-level piano/EP sounds and playability in a rugged, straightforward package. If you’re a pianist looking for an affordable workhorse keyboard, look no further than the Grandstage. I highly recommend you visit your local music store and try one out.
