A collaboration between Novation and Isotonik Studios has produced a wonderful Max for Live device called, LaunchSync.

LaunchSync is a solution to a problem that I didn’t think could be solved, and it’s free! It allows you to sync the various controllers that you’re using in Ableton Live. So, no more worrying about whether or not you’ve banked all three of your Launchpad Minis to the same tracks within a set; if your Ableton Push and Launch Control are controlling the same tracks; etc. Everything will be synced! 

Create Digital Music’s Peter Kirn explains it’s uses more elegantly than I can:
1. One Ring to Rule Them All. Have every grid controller assigned to the same block of clips, and move around together (one clip at a time, or “paging” in bigger groups).
2. A Wider or Taller Grid. Make a bigger grid. For instance, a Push and a Launchpad, or two Launchpads could be next to one another, moving together – 16×8 or 8×16 or whatever you like.
3. Faders Synced with a Grid. Get your faders following your grid. I love Push, but I’ve hesitated to use it live because I can’t easily mix on it. Now, I can have my LaunchControl XL follow the launch grid of the Push.

Here’s a video of it in action:
