Right, I want to use my PC to record, sample, loop, create, mess about with and generally try and make music. I've got a copy of Cubase on the way, am planning to get a keyboard in the very near future, speakers amp etc... I'm a total beginner at this, so I'll be learning as I go along... but to get started I need some help. What else do I need? - - - mixer? cables? soundcard? - please recommend a soundcard, as I have to buy this seperately from the PC. However obvious, please advise!
