5. Setup
5.1. Connecting to a Computer (PC/Mac)
- Connect one end of the supplied USB cable to the USB port on the MICROKEY261.
- Connect the other end of the USB cable to an available USB port on your computer.
- The MICROKEY261 is class-compliant, meaning it typically does not require special drivers for basic functionality on most modern operating systems (Windows, macOS). However, for advanced features and optimal performance, Korg recommends installing the latest Korg MIDI driver from the official Korg website.
- Once connected, your computer should recognize the device. Open your Digital Audio Workstation (DAW) or music software and select the MICROKEY261 as your MIDI input device.
5.2. Connecting to an iOS Device (iPad/iPhone)
- You will need an Apple Lightning to USB Camera Adapter (or equivalent) to connect the MICROKEY261 to your iOS device.
- Connect the USB cable from the MICROKEY261 to the USB port on the Camera Adapter.
- Connect the Lightning connector of the adapter to your iOS device.
- The MICROKEY261 will be powered by your iOS device. Ensure your iOS device has sufficient battery charge.
- Open your music application on the iOS device. The MICROKEY261 should be automatically recognized as a MIDI input.

5.3. Korg Kontrol Editor Software
The Korg Kontrol Editor software (available for free download from the Korg website) allows you to customize various settings of your MICROKEY261, including:
- Velocity curve adjustment (how the keyboard responds to your playing dynamics).
- MIDI channel assignment.
- Customizing the function of the assignable switch input.
- Transposition settings.
It is recommended to install and use this software to tailor the controller to your specific needs.

6. Operating Instructions
6.1. Basic Playback
Once connected to your computer or iOS device and configured in your music software, simply play the keys to generate MIDI notes. The velocity-sensitive keys will transmit different MIDI velocity values based on how hard you strike them, allowing for expressive performances.
6.2. Pitch Bend and Modulation Wheels
- Pitch Bend Wheel: Move this wheel up or down to smoothly change the pitch of the notes you are playing. It typically returns to the center position when released.
- Modulation Wheel: Move this wheel to apply modulation effects, such as vibrato, to your sound. The specific effect depends on the instrument or synthesizer sound selected in your software.
6.3. Octave Shift Buttons
Use the OCTAVE DOWN and OCTAVE UP buttons to shift the entire keyboard's range up or down in octaves. This allows you to access a wider range of notes than the physical 61 keys provide. LEDs next to the buttons indicate the current octave shift.
6.4. Assignable Switch Input
Connect a standard sustain/damper pedal (sold separately) to the assignable switch input. By default, this input functions as a sustain pedal, holding notes even after you release the keys. The function of this input can be customized using the Korg Kontrol Editor software.
7. Maintenance
7.1. Cleaning
- Wipe the unit with a soft, dry cloth.
- Do not use abrasive cleaners, waxes, or solvents.
7.2. Storage
- Store the unit in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid placing heavy objects on the unit.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Unit not recognized | USB cable not connected properly or faulty. Computer USB port issue. | Ensure USB cable is securely connected. Try a different USB port or cable. Restart your computer. |
| No sound from software | MIDI input not selected in software. Software instrument not loaded or armed. Volume too low. | Check your DAW/software settings to ensure MICROKEY261 is selected as MIDI input. Load an instrument and ensure its track is armed for recording/playback. Increase volume. |
| Keys not responding consistently | Velocity curve settings. Dust/debris under keys. | Adjust velocity curve in Korg Kontrol Editor. Gently clean around keys. If problem persists, contact support. |
| Pitch/Mod wheels not working | Software instrument does not respond to pitch bend/modulation. | Verify that the software instrument or effect you are using is configured to respond to pitch bend and modulation messages. |
