Its the old question, Mac or PC with a twist. I have (and dont know how) got the go ahead for a Class, yes CLASS of computers. I have used PC but now I am thinking of Mac's. I have always had problems with Sibelius and the latency issue when using USB keyboards, midi guitars and drum kits plus multi track recording using cubase and audicty. I need a computer which will play the sound from the keyboard when I play it, not 1/2 a second later. I also need a laptop which can multi track, one which will play back a track so you can add tracks live and record 12+ tracks at the same time and be able to eq settings later. These will be on our school network,(RM) CC4. My question is, in this day of development and impending doom of a computer being outdated before it arrives, what do you use for Sibelius 6 onwards, multitrack recording and day to day use on a RM network. Will a mini mac, i5 4GB ram 500GB HD do the job for a class machine as I am short on bench room as well as compete in 2-3 yrs time. apparently this is 70% quicker and far more stable than the latest HP touch smart 520-1030 which has been looked at! Thank you so much in advance, I would like to use your comments in the meeting if possible, let me know.
