Hi,

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.

Pros:
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

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

Cheers

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
