What exactly is the buffer size? For instance, I have the M-Audio Firewire 410 and in the software interface I can change the buffer size down to 64, and this gives me a low latency in Guitar Rig 2. However, when I raise it I get a higher latency. I figured a buffer meant how much memory is allocated to a specific task, and if there is more memory, shouldn't I have less latency? Also, even though I change the buffer to 64 in my control interface, when I load the audio setup in Cubase LE it automatically sets my buffer at 5512. The buffer in Guitar Rig 2 changes based on what my Firewire 410 is set at. If I try to change it manually, down to 64, the lowest it goes is to 512. I can't seem to get the audio sync test to work right, it always fails.
