Studio One has some of the best time stretching features I've seen in a daw. Also u can extend or shorten a track without changing the pitch. The audio quantizing is pretty simple as well.Using its Impact vst pad, u can do some real damage. U can even save ur sample in a folder on the fly. U can record a vst instrument, qquickly transform it to audio, save the audio in ur browser (thru S1 linking to the browser), throw that on some Impact pads and jam out.... all within maybe 15 seconds tops.
