interested on your thoughts on virtual DJ have been using it via USB into my mixer along side my old school 1210's mainly for music i cannot get on vinyl either MP3 and CD, overall i have been fairly impressed for a free bit of software not noticed any sound quality issues and I'm pretty anal about these things, however i have not recorded any sets yet and only rarely get a chance to mix, its mainly i hold over from my teen years which i still enjoy after a few beers.
