i recently got a launchpad and did not find a patch in the forums, that was good for me, so i made a new one :)

If you want you can check it out.

pretty abstract, one subpatch with LED-ID (midi note) as parameter makes global changes to colors really easy, can disable single rows with "play" buttons to the right, can be included as subpatch

Lots of global receives and sends (all starting with "lp_")


Update: I've made some addtions and also created a virtual midi instrument with presets for hydrogen (in drum rack mode). Works pretty good, but a way to synchronize to a global time would be nice...

For easier access you can check out the patch, along with much more other stuff on github: https://github.com/noreabu/pd
