I´m thinking of buying some stuff so I can record some music. I wan´t to use a Mbox for audio and a little USB MIDI interface for some sort of synth. The thing is first of all I need a new computer. I have a 400mhz with 64mb memory and I wan´t to use Cubase SX. How fast and how much memory do I need to get a good recording computer? Do I need more than 160gb? Is there anything else i need to think about when buying these stuff? I´m totally new to this!
