How do I set up my synths / computer to record properly?!

[benroles]

Hi all,

New member here with a question! Over the past few years I've purchased various synths etc. and coming from a piano-playing background am pretty adept at flying round the keys when i feel like 'jamming' (with myself!). I've also hooked up my synths etc. at various different times to my computer. However, generally all my kit isn't hooked up to each other and whilst playing around is fun I want to get in to properly composing / recording etc. Can you help me please with regards to how I should go about hooking things up together. At the moment I have:

Virus TI Keyboard (has MIDI, can be a MIDI controller and USB link)
Korg Radias (MIDI only I think)
Korg Kaossilator (ordered the other day but has MIDI and can be a controller?)
Roland Fantom S (MIDI)
Roland VP550 vocal harmoniser (only audio out I think)

At the moment I have them all plugged in to a noddy mixer to allow me to play them 'all' and get sound out.

I already have cubase software on my PC that I bought a while ago but have never used it fully.

So in essence I think I just need to know what audio cards / controllers I need and also what mixing equipment or similar I need? I guess the MIDI / USB etc. controlled synths etc. I'd conrol from the PC but I also need to be able to capture the sound from things like the VP550. As an aside, I'd like to be able to record some acoustic sound (guitar, harmonica etc.) as well as vocals.

Can somebody please help me put together my set-up?! Basically a 'how to' and 'equipment needed list' would be superb.

I ultimately want to be able to control my instruments, record the sounds that cannot be controlled (e.g. vocals) and mix together the output.

Thanks so much for your help.

Ben.
