I am looking to purchase some software and any other hardware i need to give me the ability to mix on my G5 Mac. I have tried some programs but they do not give you the option to listen to the cued music seperate from the main speaker output. How do you do this and can i also do it on my laptop G4. I have mixed on dacks formany rears and fancy ditching the cd turntables for my comp. Any help no matter how simple is greatly appreciated.
