What Else Do I Need For My Setup?, I have a IMac G5 20", DP 4.5, .......... Options

Hi Everyone,

I currently have the new IMAC G5 20" with 2GB of ram. I'm using digital performer 4.5 and have recently bought a tascam FW1884 for my audio interface. I also have a Korg Triton Le-88 Workstation, Mackie hr824 monitors, 2 AKG C1000S and 2 AKG C3000B mics. I haven't really started recording anything but mostly just reading manuals and playing around with things in digital performer recording keyboard riffs and licks. I'm curious or kind of confused on what else I need as far as compressors, mic-preamps, additional hardware, possibly a midi controller to complete a basic set-up to where I can begin playing around and start to learn the ins and outs of recording live music as well as writing a lot of beats and electronic music. Any advice on how to improve my set-up and maximize my set-up is extremely appreciated. Thank you.

Ryan.
