Clip Mapper is a M4L Device that allows the user to assign 16 parameters to a clip and recall those parameters when an assigned clip is triggered.

The 8 knobs and 8 buttons on this device can be controlled using MIDI Learn or Automap. The knobs and buttons can be assigned to any device on any track. You could for example have all your bass control parameters assigned to Clip 2 on Track 2 and all your beat control parameters assigned to Clip 1 on Track 1. By triggering either of those clips, the chosen parameters will be available to control with the Clip Mapper Device.
This allows you to free up many knobs and buttons on your physical controllers. And you don't need to memorize how to recall the correct controller presets during a live situation.
