Well, I've bought it, and right now, I'm just having fun exploring all the sounds....there's a HUGE library, with effects to boot, so I'm just screwing around with that, and slowly reading up on the manual. I've almost finished one goofy "dance" song, nothing special. Working on a delay heavy dub thing now. I'm still lost when it comes to editing...some of my stuff is a total mess cuz the looped beat falls right out of time...need to figure out how to shorten things, and whatnot.
Plenty to learn, but I have to say, well worth the price. This should keep me busy over the cold winter.
