I am new to home recording and run pro tools 9. With a 2.6 processor 4g of ram. 1T hard drive just fro pro tools. The problem I am having is with the low latincy setting as low as I can get it so when I play my Roland drums into toon tracks there is no latincy when I have only 3-4 tracks recorded pro tools locks up. Also locks up when I bounce to disk. Also locks up when playing back with more the 2 tracks recording. When I put the setting back it works fine and run 20 takes with FX play back is fine and bounce to disk works fine. The question I have is : Will a good sound card ( not the built in one that I have ). Help with not making the prossor work so hard and lock up the pro tools? Also witch sound cards are the best for taking most of the prossor not work so hard.
