Before any long session with cubase , i shut down all virus software , and any other silly programs.I then scan disk , and before that i would defrag .I have not set up my computers virtual memory like some websites tell you to , i find it causes more problems than it fixes. I run on 500 mgz with 394 meg of ram . i used to have 128 meg of ram . i never noticed any difference when i upgraded. Most of my effects are mainly off board , but i can run up to 5 or 6 easy , be carefull with the reverbs tho . flangers been the most demanding on the chip .Always save the file as a song , its quick and you wont lose your work if it crashes .Avoid editing in the cubase audio editor , i integrate cool audio pro ( free down load ) . I always reccord at 44.1 , anything above is silly .I reccomend the s b live soundcards as a quiet line in out medium , the onboard sounds i find thin .More soon ........!
