If you want immediate hands-on control of your session grid, instruments and effects, you should use a MIDI keyboard controller that integrates immediately and automatically with Ableton Live. The less time you spend messing with your mouse, the more time you have for making music. You can choose between 25, 49 and 61-note versions, depending on whether you want portability or practicality. The Launchkey synth-style keyboard is lightweight, fast and very easy to play, but also velocity-sensitive so you can create truly expressive performances. The heart of any MIDI keyboard controller is the keyboard itself. Of course, if you don't use Ableton, it'll automatically map to other major music software too. 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. It's pretty much the quickest and easiest way to produce and perform electronic music, especially in Ableton Live because they designed it specifically for the purpose. Launchkey is Novation's easy-to-use MIDI keyboard controller. Essential Keyboard Controller for Producing Electronic Music in Ableton Live
