Fruity Slicer makes it so easy to chop its ridiculous, so imma have to go with fruity slicer. For looping, any audio editor can do that as long as you have a cut tool.....
Audacity for chopping samples all the way. I've tried it in FL, Reason, Acid as well, but the free resource of Audacity has the best interface to manually chop samples well. Looping, that is a different matter...
