Relaunch is a helper application for using a Novation Launchpad with Reason and Record.

To use this (free!) app, you must first install the LoopBe midi driver from:

http://nerds.de/en/loopbe1.html

Then install ReLaunch from

http://www.deluded.co.uk/Relaunch.zip

Finally, on Reason or Record, add the LoopBe midi interface as a generic MIDI keyboard.

Run Relaunch, and you’ll see the buttons map to the drums in ReDrum. With any luck, it will also work in Kong in Reason V5. If not, I’ll fix it when I know how!

edit: Tested working 100% with Kong
