I've been using soundforge for years.. i use it to bring a single vocal track in and add effects to certain vocal parts and to edit vocal parts of single tracks... I also use soundforge to master the final render, bounce, or mixdown ... and the best thing about soundforge is that i can make sample loops out of any track i wish. I'll bring in some 70's music and pull out some samples of drums and then upload it in acid pro as a loop.. i can sample ALLLLLLLLLLL day ...
