These controllers are mainly made for music, but you can easily use them for VJing. Let's learn how to easily link your device to Resolume.
In the first place you will need a Korg USB controller from the following list: microKEY Air (microKEY Air-25/37/49/61), microKEY2 (microKEY2-25/37/49/61), microKEY (microKEY-25/37/61), nano Series2 (nanoKEY2, nanoPad2, nanoKONTROL2), nano Series (nanoKEY, nanoPad, nanoKONTROL), taktile (taktile-25/49), TRITON taktile (TRITON taktile-25/49), nanoKEY Studio, nanoKONTROL Studio.
#1 Download the Korg USB-MIDI Driver at http://i.korg.com/SupportPage.aspx?productid=596. Select your device model from the dropdown menu. Download the corresponding .dmg (MAC) or .zip (PC). Install the driver.
#2 Download the KORG KONTROL Editor at http://www.korg.com/us/support/download/software/0/159/1355, install and open it. Select your target device and click OK. Go to File > Save As... > "default" or similar. Now you can configure your controller as you want. For example, the button behavior is set to "Momentary" by default, maybe you want to change it to "Toggle". You can modify the knob and slider ranges too. After you complete your setup, go to File > Save As... > "your_new_preset"; go to Communication > Write Scene Data > OK.
#3 Finally, launch Resolume and go to Avenue/Arena > Preferences > MIDI and set your KORG controller as MIDI input. Now you can assign your control channels (Mapping > Edit Application MIDI Map).
