last week I bought myself a Novation Launchpad. Since (afaik) Resolume Avenue does not support Midi Out to let the Buttons glow I coded a little sketch right before a gig in processing. It lets the Launchpad glow and communicates with Avenue. So if anyone is interested you can find it on my website:

(you need Processing and the libaries which I used to run it)
As I said it was just before the gig that I did this so there are a few things which are not 100% correct. Even though it was really fun to VJ with it.
For the future I plan to use it as a sequencer for Resolume.
The sad thing is that Avenue does not seem to send OSC commands. So if you trigger a clip with the mouse the launchpad has no chance of knowing what you did.

And I noticed that when you trigger clips very fast it tends to get laggy quite noticably.
Also there are some OSC commands which I miss ... like changing decks.
Any ideas about these topics?
So much for now and hopefully I will soon have a sequencer ready.
