Digital Piano Korg Grandstage 73 Full Review. Is it a good choice?

Korg Grandstage 73 Review Complete Digital Piano. Is it a good choice?

Korg is a Japanese company of electronic musical instruments and guitar tuners. And this time we will analyze a very very powerful digital piano that competes with the CP4 and the all-powerful NORD. We are talking about the Korg Grandstage 73. It has a price of €1.599/$1999/£1,499 and the article is also very interesting:

  • 73 weighted keys (Weight that the keys of an acoustic piano have and that digital pianos try to imitate to equal the touch of the piano. The keys in the high register are heavier and in the high register less. This is different from the sensitivity on the keyboard which serves to regulate the volume of the note. But a weighted keyboard always has sensitivity in the keys) with Real Weighted Hammer Action 3 touch and velocity sensitive technology
  • It has five concert grand pianos and several upright pianos
  • 128 notes of polyphony (Number of notes that can be played at once. This includes accompaniments that also consume notes. So if you play on top of an accompaniment more notes will be accumulated) maximum with 7 sound engines
  • 500 sounds (Different sounds of piano and other instruments)
  • 2 screens with OLED technology
  • 3-band equalizer and 4 insertion effects
  • Reverb Effects (Reverb Effect)
  • Delay effects
  • Split function (dividing the keyboard into two different instruments) and dual
  • Modulation wheel
  • Pitch bend wheel (Functionality that changes the sound wave of what you play and then returns to its original state)
  • It includes a power cable and a music stand (Standard-M-SV)
  • Includes ‘Damper’ pedal (DS-1H) which is a sustain pedal (The sustain pedal of a piano or keyboard is used to keep the note playing even if you stop pressing the key)
  • 2 balanced Canon XLR stereo line outputs
  • 2 line jack outputs
  • Stereo headset jack output
  • It has tickets for Damper, Switch and Pedal
  • USB-A input for pendrives
  • USB midi (MIDI allows you to do such wonderful things as connect your keyboard to your computer, record a sound track and with certain programs click through what you’ve played to musical notes on a score. MIDI tracks store the information of the musical notes)
  • A weight of 17 kg and dimensions of 1099 x 359 x 140mm

demo review korg-grandstage-73

 

Now that we have listed and described the features of this keyboard there is no better way than to take a look at the following reviews where they tell us more about the Korg Grandstage 73 and you can hear how its different sounds sound.

Now let’s compare the Korg Grandstage 73 with its more common alternatives. Also at the end of the post you will find a section with the best shopping possibilities for this digital piano. But you can go directly to that part of the post by pressing the following button.

Korg Grandstage 73 vs Korg SV2 73

The first comparison will be of the following keyboards: the Korg Grandstage 73 keyboard which has a price of €1.599/$1999/£1,499 and the Korg SV2 73 with a price €1.799/$1899/£1,666, with a difference of €166 we will analyze the differences and similarities of the equipment:

  • Both computers have 73 speed-sensitive and weighted keys. Let’s remember that sensitivity refers to the option or function of being able to make dynamics in our interpretations, that is to say, when we press a key with a higher sonorous force than another when we touch it with less force. Weighted keyboard refers to the weight that the keys have in a real acoustic piano, in the low range they are heavier keys while in the high range they are lighter keys.
  • The Korg Grandstage offers 500 sounds, with 128 notes of polyphony with 7 sound engines. The Korg SV2 73 offers 74 preset sounds and 64 you could choose as your favorite, with 128 polyphony voices. Polyphony is the most notes that can dine at the same time on a computer.
  • The functions that characterize the Korg Grandstage 73: 3-band equalizer and 4 insert effects, effects such as: Reverb, delay, split and dual function, modulation wheel and pitch bend. It also includes a sustain pedal.
  • The functions that characterize the Korg SV2 73: Stereo Mastering Limiter, effects section with real tube circuit (which you normally see on guitar amps), Amp Simulation, and a lot of effects. Plus three pedal inputs.
  • The Korg Grandstage 73 has 2 balanced Canon XLR stereo line outputs, 2 jack line outputs, and a stereo headphone jack output.
  • The Korg SV2 73 has 2 balanced XLR line/unbalanced 6.3 mm jack outputs, 2 unbalanced 6.3 mm line jack inputs and Stereo Headphone Output.
  • Both keyboards have a USB MIDI function, which allows them to be connected to a computer to be used as MIDI controllers in a music production and composition program.
  • The Korg Grandstage 73 has a weight of 17 kg and dimensions of 1099 x 359 x 140mm and the Korg SV2 73 has a weight of 17.2 kg and dimensions of 1143 x 157 x 347 mm (W x H x D).

We have two fasting keyboards marked but for two purposes. The Korg Grandstage 73 really is a good stage keyboard given its many flaws and functions. The Korg SV2 73 although also a stage keyboard, has a vintage look and style, besides its functions it also reminds us of keyboards, synthesizers and organs from the 70’s onwards. According to your needs you will make the best decision.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg Grandstage 73 vs Yamaha CP4 Stage

Now we will compare the following keyboards: the Korg Grandstage 73 keyboard which as we have already mentioned has a price of €1.599/$1999/£1,499 and the Yamaha CP4 Stage which has a price of €1500, we will see their differences and similarities in the next section:

  • The Korg has 73 speed-sensitive and weighted keys. While the Yamaha has 88 keys with the same characteristics. Let’s remember that sensitivity refers to the option or function of being able to make dynamics in our interpretations, that is to say, when we press a key with a higher sonorous force than another when we play it with less force. Weighted keyboard refers to the weight that the keys have in a real acoustic piano, in the low range they are heavier keys while in the high range they are lighter keys.
  • The Korg Grandstage offers 500 sounds, with 128 notes of polyphony with 7 sound engines. The Yamaha CP4 offers 433 preset sounds, with 128 polyphony voices. Polyphony is the most notes that can dine at the same time on a computer.
  • The functions that characterize the Korg Grandstage 73: 3-band equalizer and 4 insert effects, effects such as: Reverb, delay, split and dual function, modulation wheel and pitch bend. It also includes a sustain pedal.
  • The functions that characterize the Yamaha CP4: Pitch Bend and Modulation Wheels, 4 Zone Split Function, Dual or Layer Function and 11 different Effects.
  • The Korg Grandstage 73 has 2 sustain pedal inputs included and 2 controller pedal inputs.
  • The Yamaha CP4 has stereo line jack outputs and headphone output.
  • Both keyboards have the USB MIDI function, which allows them to be connected to a computer to be used as MIDI controllers in a music production and composition program.
  • The Korg Grandstage 73 has a weight of 17 kg and dimensions of 1099 x 359 x 140mm and the Yamaha CP4 73 has a weight of 17.5 kg and dimensions of 1332 x 161 x 352 mm.

Both interesting proposals in which it is proposed, for its part the Korg has 73 keys, 500 sounds with 128 notes of polyphony and 7 sound engines. And the Yamaha offers a keyboard with 88 wooden keys and 433 sounds with 128 polyphonic notes. Both are good options, but the measurements make a big difference. If you have little space, the Korg will help you more, or if you have some space left over and want to have a full keyboard, the Yamaha is for you.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg Grandstage 73 vs Clavia Nord Piano 4

We will now have the following comparison of digital pianos: The Korg Grandstage 73 keyboard which as we mentioned before is priced at €1.599/$1999/£1,499 and the Clavia Nord Piano 4 which is currently priced at €2.399/$2999/£2,199, with a difference between them of €733. Let’s see then its face to face:

  • The Korg has 73 speed-sensitive, weighted keys. While the Nord has 88 keys with the same features, sensitive and weighted.
  • The Korg Grandstage offers 500 sounds, with 128 notes of polyphony with 7 sound engines. The Nord 1 Gb Storage for the Nord Piano Library and 512 Mb Storage for the Nord Sample Library, with 120 polyphony notes for the piano part and 30 polyphony notes for the synthesizer.
  • The functions that characterize the Korg Grandstage 73: 3-band equalizer and 4 insert effects, effects such as: Reverb, delay, split and dual function, modulation wheel and pitch bend. It also includes a sustain pedal.
  • The features that characterize the Clavia Nord Piano 4 are Numeric Pad Mode, Layer and Split Function, All Effects in Stereo and three types of Reverb Effects with Bright Option
  • The Korg Grandstage 73 has 2 sustain pedal inputs included and 2 controller pedal inputs.
  • The Nord has a mini-jack monitor input, 1 jack headset output and 1 jack input for the footswitch. Also a TRS Jack volume pedal input
  • Both keyboards have the USB MIDI function, which allows them to be connected to a computer to be used as MIDI controllers in a music production and composition program.
  • The Korg Grandstage 73 has a weight of 17 kg and dimensions of 1099 x 359 x 140mm and the Clavia Nord Piano 4 has a weight of 20 kg and dimensions of 1287 x 121 x 340 mm.

We found good equipment for what they were created for, stage pianos. As in the last comparison the measurements are somewhat relevant, however the North offers many more functions and sounds than the Korg, not for nothing this together with other models of the brand are popular among professional musicians. It is really worth going to the other level, if you have the budget to do it.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg Grandstage 73 vs Roland RD-2000

This time we will buy the following digital pianos: The Korg Grandstage 73 keyboard which is priced at €1.599/$1999/£1,499 and the Roland RD-2000 which is currently priced at €2.290/$2599/£2,090, giving a difference of €624. We will see their similarities and differences in the next section:

  • The Korg has 73 speed-sensitive, weighted keys. While the Roland has 88 keys with the same sensitive and weighted keyboard features of hybrid wood-plastic construction, which are of great quality.
  • The Korg Grandstage 73 offers 500 sounds, with 128 polyphonic notes with 7 sound motors. The Roland offers 1113 sounds, with 128 notes of polyphony.
  • The functions that characterize the Korg Grandstage 73: 3-band equalizer and 4 insertion effects, effects such as: Reverb, delay, split and dual function, modulation wheel and pitch bend. It also includes a sustain pedal.
  • The functions that characterize the Roland RD-2000 are Eight knob controls and nine slide controls, you can also split into eight different zones, layer function.
  • The Korg Grandstage 73 has 2 sustain pedal inputs that are included and 2 inputs for controller pedals.

We can see that the Roland is a winner in many aspects, such as the amount of sounds, many physical controls that allow the use of the different functions that the keyboard has. But as we have also commented in previous comparisons, the width measurements are revealing with 73 and 88-key keyboards. Surely with this face-to-face you know what you need best.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:

Korg Grandstage 73 vs Yamaha CP73

Finally we will look at the following digital pianos: The Korg Grandstage 73 keyboard with a price of €1.599/$1999/£1,499 and the Yamaha CP73 which is priced at €1.644/$1999/£1,499 , with a small difference of only about €20, will be a more than interesting face-to-face. Let’s get to it:

  • Both units have 73 speed-sensitive and weighted keys.
  • The Korg Grandstage offers 500 sounds, with 128 notes of polyphony with 7 sound motors. The Yamaha CP73 offers 80 sounds, with 128 polyphony voices.
  • The functions that characterize the Korg Grandstage 73: 3-band equalizer and 4 insertion effects, effects such as: Reverb, delay, split and dual function, modulation wheel and pitch bend. It also includes a sustain pedal.
  • The functions that characterize the Yamaha CP73 : Seamless Sound Switching, All the functions with direct access, optimized for musicians of stage, a great amount of effects and two entrances of pedals.
  • The Korg Grandstage 73 has 2 balanced Canon XLR stereo line outputs, 2 jack line outputs and Stereo Headphone Jack Output.
  • The Yamaha CP73 has Stereo Output (6.3mm jack and XLR), Stereo Headphone Output (6.3mm jack) and External Stereo Input (6.3mm jack).

  • The Korg Grandstage 73 weighs 17 kg and measures 1099 x 359 x 140 mm, and the Yamaha CP73 weighs 13.1 kg and measures (W x D x H) 1086 x 355 x 144 mm.

We find two interesting proposals for digital stage pianos. On the one hand, the Korg, which as we mentioned before has a great amount of sounds and functions relevant for a stage piano, now we also find Yamaha, which has high quality sounds and a function that I think is essential in a digital stage piano, the SSS, Seamless Sound Switching, so that you can have a better performance on stage. You always have the last decision, we advise you to watch the videos and listen to the sounds with a quality audio equipment.

We will put the characteristics of each of these pianos in 2 different columns to make it easier to see the differences:
