This product is nothing but a scam, do not waste any money on it at all. Any track I tried ended up either very quiet with the lead vocal still audible or with tons of echo and again the lead vocal still audible. When I contacted the company they had an excuse for everything and strangly enough it was all my fault. When I asked them if I could hear a track they had succeded in removing the lead vocals from so I could verify that it was indeed possible to actually do it their e-mail replies stopped. This is nothing but a con. Please tell all of your friends and anyone who will listen not to touch this rubbish with a barge pole
