The Novation Launchkey 25 MkII is the essential keyboard controller for producing electronic music in Ableton Live
Launchkey is our easy-to-use MIDI keyboard controller. It's pretty much the quickest and easiest way to produce and perform electronic music, especially in Ableton Live - because we designed it specifically for the purpose. You just plug in via USB and the keys, faders, knobs and pads immediately spring into life, giving you hands-on control of your grid, instruments, effects and mixer.
Of course, if you don't use Ableton, it'll automatically map to other major music software too.
