ive used this program on various occasions for making mixes, but find its bollocks for doing sets or any extensive length of mix. the most useful thing is being able to mix two tracks together fairly easily but keeping a chain going is nigh on impossible to do effectively. ive had a laugh putting ff7 midis with greasy drumand bass and other stuff, but have had to export them seperately and mix them up elsewhere. not really a great dj kit in my eyes, but has its uses. if you wanna seriously do the spin then buy some decks or use traktor, its much better. but as i said this was a free program and aint all bad.
