Nice ! New features I didn’t know 
The MPE seems really powerfull too. Now I’m polishing my linux workstation (finally, I choosed a minimal Ubuntu 10.04LTS +RT kernel+Jack, dual core and plenty of ram, instead of using a music dedicated distribution), then I’ll learn Renoise (and buy the licence), and play around with my controllers (KDJ500 + mpd clone). And, later, I’ll see what I should add into my setup. Probably a grid controller, I guess, but maybe not. I need to see how everything works together, first. And save money, since the launchpad appears to be the way to go (or if I can save a LOT of money, a Livid grid controller… 
)
Again thank you for your help and your patience.
