Thanks to this article by sonic bloom I downloaded MashUp by Ned Rush. Great tool (if you’re into glitch, bad if not). It’s free until the end of 09/2014, so you should give it a try. It’s working great on melodic stuff, loops, one-shots, drums, percussion, maybe everything!
Check out the video to get a first impression (funky drummer and amen brothers: two of my favorite breaks included, too). Have fun with grinding your sounds.[youtube http://youtu.be/LyEtabMk-uM]
