Because why not.
I just got Renoise, moving up from Milkytracker, and so far I absolutely love it. I dabbled around in the likes of FL Studio for a little while but the setup is stupid - piano rolls and step sequencing, bleh. A DAW with a tracker interface and some really, really nice workflow ideas is a much better, much more usable option in my opinion.
Anyways, assuming you use Renoise, why not share your favorite techniques for making chip-style music? Your favorite tools/scripts? Or even just pop in to say you love such and such artist for using the program as well.
