I currently have a computer set up specifically for music including BIAB 2009.5 everything pak copied from ext hard drive to computers hard disk along with Sonar. Windows XP. No internet connection. All is good. I'm interested in purchasing a new computer that I will be using for internet, Microsoft Office and some music related software (general home office use). As a keyboard player most of the music stuff loaded would be software to tweak and store keyboard settings for varios boards. Mostly utility software for keyboards. I was thinking of also using this computer for BIAB but running off the small external hard drive provided by PG Music. Would like the fleibilty of having BIAB on both computers. Although most of my recording and songwriting would be done on the "music computer", can anyone offer suggestions in regards to processor ( dual or Quad), ram (3-4 gig) and hard drive space needed for good results on this new computer. In regards to souncards, does anyone use the Echo Mia midi or can suggest an M-audio equivalent. I will continue to use XP pro as I have had good luck with this OS. Presently thinking of a custom build and not the Dell/Hp route. I would like better control over software and hardware than the ready made companies offer. Any response appreciated
