I record a couple different kinds of racing, and also film short skits. Usually i just go through my itunes library and throw something in for the race videos.. thats getting old though and the words are annoying Usually do some sort of quick paced rock song since its to help promote tracks and get people to come race wherever. I also do some small skits that need a wide variety of "feel" to them. I have tinkered and tinkered in garage band but in the end dont come up with much. I am pretty sure i need to buy some addons for it if i go that route. I have even considered turntables to mix stuff....Or possibly a loop collection. Is there a way to pull voice out of sound tracks then mix them??? Sorry about my vague question, i am really that lost on what the best route is.
