HOLY CRAP! CRAIG! I just did the simple tweaks described here and while I have been happy with my computer and interfaces performance, I am blown away. I just finished running a 32 track project with the 2 Studio Captures. Before the tweaks, this project had to run around 256 and up on the buffers. This same project is now running at 48 samples in ASIO!
This project is running 2 instances of Superior Drummer, 1 instance of Garritan, 1 instance of DimPro, 1 instance of Addictive Keys, and every audio channel is decked out with console emu, QuadCurve, compressors and gates, etc.
I just loaded up everything but the kitchen sink. This project used to sputter around 256. Now, everything is running like a top at 48 and the computer is looking at me like "Is that all you got?"
Thanks, guys! This is by far the best fix anyone has donated here. Another reason to say if you want to learn about digital recording from top to bottom, this forum is the place to be.
