The Launchpad by Novation comes in the second generation and offers a complete RGB backlit button- and 8x8 Grid-surface. Primarily the Novation Launchpad mkII is made especially for Ableton Live DAW, but it can be used with every other sequencer software as well. The huge advances when using it with Ableton Live are the many functions that can be transfered from Live directly to your Launchpad Grid surface including all colors. So it is possible to for example transfer the Session view of Live to the Launchpad which allows you to launch clips, record audio or edit and mix your tracks. The controlling options are nearly endless in combination with Abletons DAW so your workflow gets optimized while adding many other features. The Novation Launchpad is moreover a Grid instrument for creating drumloops and beats.
