Starting Out, Sound cards? Options

[bede66]

Right, I have a mac powerbook G4 and want to start makin music. I used to use a lot of hardware samplers, keyboards and the like but I am totally new to macs. Questions i'm askin here are: Do i need a soundcard and if so any recomendations. I want a ontroller keyboard and was lookin at the m-audio oxygen or something similar, but do i still need a soundcard and is it external or internal. i really don't have a scooby. any help would be appreciated cause i want to start writing some tunes.
