Ok so if any of you remember me from posts about a week ago I had a problem with playback in pro tools. When ever I was playing a virtual instrument like the mini grand every now and then the playback would glitch up and stop then continue after about a half a second. This was before I had my second hard drive installed so anyway I have put the second hard drive in and save my pro tools file to its location when I start up a new session. It seems the second hard drive is helping a lot it happens a lot less it seems though it still is happening more than id like. So then I tried the using only 1 processor trick I heard helps a lot so I disabled my hyper threading processor and set it to 1 that seems to help keep these glitches away a little more too. But I still get them more than id like what should it do? To me it seems to be the processing power I have a 3.0ghz P4 I follow the cpu usage and the second I play its just too much it seems even just having pro tools loaded up is alot. Or would it be the RAM I only have 1gb I know its low but right now I have no interest in recording multiple tracks just having 1 up for playing in virtual instruments, so what is causing this problem? Also to add, these little playback glitches even happen out of pro tools when playing back thru my mbox 2 mini, just randomly thru a song I'm listening to it will freeze real quick then continue and when I load up a song it takes longer than normal to start than if I just played it thru sound card.

1 more thing the DAE playback buffer, for this issue I'm having which level for me to use would make the most sense to use 0-4? or would that not matter at all for me? and increasing H/w buffer size doesnt seem to help and the higher the less responsive my key strikes are
