Launchpad is a utility that allows for the automatic filtering of messages from the Novation Launchpad into Max/MSP in a convenient format, and allows for lighting feedback to be sent back to the launchpad. It also includes programming to allow for the top row to be used for 'menu' style function, i.e. one 'page' being open at a time, and the launchpad reflecting this. There is also the function to clear all lights. It also works with M4L.
This patch now has variants to ensure it works with both 32bit and 64bit versions of Max and Max4Live, along with versions for FTM users.
