This is a very quick and rough tutorial on how to set up a Novation Launchpad to operate as an emulated Monome using the application Nonome. I demonstrate this on my Mac OSX but it should work on any operating system that will run monome apps - set up your computer to use a monome and monome apps by following the set-up instructions for your OS found at this link:
docs.monome.org/doku.php?id=setup

Nonome (and it's user manual) can be found here:
post.monome.org/comments.php?DiscussionID=6245

For this example I use the monomeserial version of the app Polygome, docs.monome.org/doku.php?id=app:polygome - but any app should work provided it is a monomeserial application (one that requires a prefix to be set in the nonome interface) at least I think that is right, but don't quote me on it.
