Korg Keystage-49 MIDI Controller Keyboard

The Korg Keystage 49-Key MIDI Controller is a next-generation performance and production keyboard built around MIDI 2.0 technology, designed for modern producers, live performers, and studio musicians who require deep integration, expressive playability, and streamlined control. It combines a high-quality polyphonic aftertouch keybed with intelligent software integration, real-time visual feedback, and a fully equipped performance control surface.

Engineered as a flagship controller for expressive MIDI workflows, Keystage delivers a tightly integrated hardware-and-software experience with support for MIDI Polyphonic Expression (MPE), DAW control, and advanced parameter mapping through MIDI 2.0 Property Exchange.

Next-Generation MIDI 2.0 Integration

Keystage is one of the first professional keyboards designed to fully utilize MIDI 2.0 Property Exchange, enabling bidirectional communication between hardware and software instruments. This allows automatic parameter detection, labeling, and mapping without manual setup.

Instead of static MIDI assignments, Keystage dynamically recognizes connected instruments and instantly maps controls such as filters, envelopes, and modulation parameters for immediate hands-on interaction.

49-Key Polyphonic Aftertouch Keybed

The 49-key version features a newly designed semi-weighted keybed with velocity sensitivity and full polyphonic aftertouch, enabling expressive note-by-note modulation. This allows performers to apply pressure individually per key for detailed expressive control beyond traditional aftertouch systems.

It supports advanced performance techniques including:

• Polyphonic Aftertouch expression
• MIDI Polyphonic Expression (MPE) compatibility
• Velocity-sensitive dynamic playing
• Extended expressive modulation per note

Dedicated OLED Displays for Real-Time Feedback

Keystage features a main OLED display along with eight dedicated OLED screens above the encoder knobs. Each display dynamically shows parameter names and values in real time, eliminating guesswork and improving workflow efficiency during sound design and performance.

This allows instant visual feedback when adjusting synth parameters, effects, or DAW controls.

Advanced Performance Controls

The controller is equipped with a comprehensive control surface designed for both studio production and live performance environments. It includes:

• 8 rotary encoders with OLED parameter displays
• Pitch bend and modulation wheels
• Dedicated transport controls
• Chord mode and arpeggiator controls
• Octave and parameter navigation buttons
• Value and page navigation controls

These controls provide immediate access to key performance functions without relying on a mouse or keyboard.

Powerful Arpeggiator and Chord Engine

Keystage includes a flexible arpeggiator system with multiple pattern types and real-time modulation options. Users can apply rhythmic variation, gating, ratcheting, and randomized behavior to create complex evolving sequences.

The chord mode features preconfigured chord sets and user-defined chord banks, allowing instant harmonic performance and creative chord triggering across the keyboard.

DAW and Plugin Integration

The Keystage 49 is designed for deep integration with modern digital audio workstations, including official support for Ableton Live and Korg Gadget. It automatically maps to device parameters and transport functions for streamlined workflow control.

When switching instruments or plugins, control assignments update dynamically, ensuring uninterrupted creative workflow during production or performance sessions.

Integrated Audio Interface and Connectivity

Keystage functions as both a MIDI controller and a USB audio interface, allowing direct connection to computers, tablets, and mobile devices. Audio output can be routed directly through the keyboard for simplified live and studio setups.

Connectivity options include:

• USB MIDI and audio interface support
• 5-pin MIDI In/Out
• Audio outputs (L/MONO and R)
• Headphone output
• Expression pedal input
• Sustain/damper pedal input

Portable and Performance-Ready Design

The 49-key Keystage is designed for portability without sacrificing performance capability. Its compact chassis and lightweight build make it suitable for stage use, touring musicians, and mobile production setups.

A detachable expansion plate allows placement of laptops or tablets at adjustable angles, creating a streamlined all-in-one performance workstation.

Software Bundle Integration

Keystage includes bundled software designed to expand production capabilities, including integration-ready instruments and DAW support tools that enhance immediate usability for music creation workflows.
