6. Joystick and joystick button
Move the Joystick along the X-axis to transmit pitch bend messages.
From the factory, the +Y axis is assigned to transmit MIDI CC 1 (modulation),
andthe-YaxisisassignedtotransmitMIDICC2.PressingtheJoystickBuon
will transmit a MIDI CC 67 message. With the Arpeggiator On, the Joystick’s
X-axis controls the type, and the Y-axis controls the duration (gate time) of the
notes.BypressingtheJoystickBuonyoucanturntheLatchfunctionOn/O.
When the Latch function is On, the Arpeggiator will continue playing even
after you lift your hand from the keyboard. (→“Arpeggiator”)
7. USB Port
Use this USB-B port to connect the microKEY Air/microKEY to your computer
using a USB cable. Connecting the USB Cable will turn the microKEY On. If
the Mode Switch (microKEY Air) is set to USB (see below), connecting the
USB cable will turn the microKEY Air On.
8. Mode Switch (microKEY Air only)
The microKEY Air can connect to your computer via USB or Bluetooth Wire-
less.
WIRELESS : ThemicroKEYAirconnectstothecomputerviaBluetooth;power

USB : ThemicroKEYAirconnectstoyourcomputerusingtheUSBcable;pow-
er is provided from the computer via USB.
Getting Connected (Connecting via USB)
Connections and power
1. Mode Switch (
microKEY Air Only
)
Set the Mode Switch to USB
and continue to Step 2. For
the microKEY, skip to Step 2.
2. Connect the USB Cable
Connect one end of the USB
cable to your computer;
connect the other end to the
USB-B port on the microKEY Air or microKEY. Use only the USB cable pro-
vided.Once connected to the computer, the microKEY Air/microKEY will turn
On;thePowerIndicatorLEDwillglowred.
TIP Windows Users :
WhenthemicroKEYAir/microKEYisrstconnectedtoyourWindowscom-
puter, the USB-MIDI driver pre-installed with the operating system will be
used automatically. This pre-installed USB-MIDI driver will not allow the
microKEY Air or microKEY to access multiple programs or applications at the
same time. To remedy this situation, simply download the KORG USB-MIDI
driver at www.korg.com and install the driver as instructed with the support-
ing documentation.
Turning o the Power
1. Disconnect the USB Cable
Disconnect the USB cable from the microKEY Air or microKEY. Once discon-
nected the Power Indicator will go dark (unlit).
microKEY Air users: Set the Mode Switch set to USB before disconnecting the
USB cable.

Customizing the MIDI Settings
Easy to use and simple in design, the Korg microKEY Air and microKEY also
allow you to access a variety of performance features and operational parameters
using the Korg Kontrol Editor software. The Korg Kontrol Editor is available as a
download directly from
hp://www.korg.com/corporate/distributors/
or from

MIDI Channel
The MIDI channel microKEY Air/microKEY should be set to match the MIDI
channel of the software or application being used.
•MIDI Channel [1...16] :ThisspecieswhichMIDIchannelthemicroKEYAir/
microKEY will use to transmit note messages, pitch bend messages, and other
MIDI messages that are sent when you use the MOD wheel, damper pedal, etc.
Keyboard
InadditiontousingtheOCTAVEUP/DOWNbuonsonthefrontpanel,youcan
also transpose the microKEY Air and microKEY to play in any musical key. In
addition, the touch response of the keyboard (Velocity Curve) can be adjusted to
matchyourplayingstyleortocreateadierenteect.
•Transpose [-12...+12] : The Transpose parameter can transpose the pitch of the
keyboard up or down in semitone steps. The range is -12 to +12.
•Velocity Curve [Curve 1...8 / Const] : Adjust the velocity curve to determine
how keyboard dynamics will aect the output level. There are eight Velocity
Curvestochoosefrom;youcanalsoselectanyxedvelocity—idealforreplicat-
ing organs, harpsichords, and other instruments that lack keyboard dynamics.

Const – The velocity value will always be constant.
•Const Velocity Value [1...127] : If Const (Constant Velocity) is selected as the
Velocity Curve, then this parameter will be available to set the Constant Velocity
Value. Every note will play with the same MIDI value selected here.
