Use the Novation Launchpad MK2 to control all clips in Ableton Live. You can keep a clear overview of things because the pads match the colors of the Ableton clips. You can also use the controller to play drums and melodies. When you're playing melodies, you can use the scale mode. This allows you to only use the right tones within the selected musical scale. This is very useful when you want to improvise live.
