I generally try and run quite a number of vst instruments in Cubase SX3 (I generally have battery open and then a Reaktor synth of some kind). Generally speaking I can't make any music because my computer just can't handle it. My laptop has a 2.8GHz processor and 512MB ram. I have an Edirol UA-20 usb1 soundcard which also acts as the midi interface for an Alesis MMT-8. Is the bottleneck in my soundcard or in the computer itself... I mean, would I be better-off with a firewire/usb2 soundcard or is the idea of having several reaktor VST's + Battery + other vst effects etc, open at the same time just an impossibility?
