MIDI keyboards with polyphonic aftertouch are becoming the next big thing in the music tech world. Native Instruments started with the Kontrol Mk3 series, keyboards designed for the Komplete software universe. Another well-known manufacturer will soon join the polyAT bandwagon. Strange: a company that recently sold monophonic aftertouch as the most prominent feature on a new Synthesizer.

B&H has leaked in the night the new Korg Keystage keyboard series. According to the leaked product pages, these are two new MIDI keyboards with polyphonic aftertouch.

The new Korg Keystage are new 49-key and 61-key MIDI keyboards featuring MIDI 2.0 integration and advanced semi-weighted keybeds that support polyphonic aftertouch and MPE compatibility. Edit: A reader pointed out that the Polytouch logo is on the hardware. So Korg purchased it from Medeli, the keyboard manufacturer but also the parent company of Ashun Sound Machines (Hydrasynth).

The controller also features eight rotary knobs with dedicated OLED displays and a main OLED displays, says the source.

Then, it comes with a powerful arpeggiator, an array of chord modes (32 different styles), an integrated audio interface, and official integration with Ableton Live. The latter puts both transport and device control at your fingertips, says the source. 

Thanks to the MIDI 2.0 bi-directional communication, all parameters will automatically be mapped and labeled for fast and easy setup. 


According to the leaked official data, the Korg Keystage will be at the forefront of keyboard innovation, being the first to truly tap into the potential of MIDI 2.0. More:

Simply connect the keyboard to compatible software, and Keystage automatically assigns parameters and even displays their names on its crystal-clear OLED screens.
Each screen is paired with a  dedicated knob for real-time adjustments, meaning you always see the parameters assigned and their exact values, empowering you to make informed decisions and act on your musical instincts without breaking your creative stride.


On the backside, you get a 5-pin MIDI interface (in/out), stereo output on two 6.3mm mono sockets for live performances, a 1/4″ expression input, and a 1/4″ assignable input. There is also a USB-B input and a power supply input with a dedicated on/off button.

Further, it will include a software bundle. You get Korg Gadget Producer Bundle that hosts most of the features and Gadgets of the regular version. There is also a wavestate native LE version which is the same plugin as the full version, expect only one plugin instance can be active in your DAW project. Plus, it comes with a license of Ableton Live 11 Lite.

First Impression

At first glance, interesting keyboards with an exciting feature set. Especially seeing polyphonic aftertouch and MIDI 2.0 in a generic MIDI keyboard is a good step into the future. Hope this is just the beginning of many new keyboards. 

According to B&H, the Korg Keystage 49 will cost $599,99, and the Keystage 61 $699,99. No information about availability.

  1. Looks like the Polytouch logo on the top-right of the keys, so this is likely a keybed licensed from ASM. I was wondering when that was going to happen.

  2. If it implements one feature of MIDI 2.0, does that require some different data format? Might there be other added MIDI 2.0 features in the future (like how it will transmit polyphonic aftertouch)?

    How does a Korg keyboard with Polyphonic Aftertouch (a la ASM Hydra) compare to a Fatar keyboard with pAT?

  3. It may be possible that it acts as an audio interface (output only). If so, then you connect to a host then feed the VI’s out to the Keystage’s outs and boom. If it did charge that does reduce a few cords.

    • these are hardware pictures from the leaked B&H page. They had some others but didn’t show the entire keyboard.

      • I understand that and to be fair it does look nice. However the NI S-61 seems to offer a lot more for roughly the same price.

        • The S-61 Mk3 costs $849 vs the Korg $699,99. So there is still a difference of $150. The downer of the S61 MK3 is that it’s not a 100% controller for external hardware.
          The S-61 Mk2 was already very focused on the Komplete software package and NKS format. As for the other features, it was more or less a MIDI controller like any other. Features like chords, etc didn’t work without the software, etc. These seams better solved in the Korg. But let’s see when they are official.
