Question about HW Buffer Size

[animas3D]

Hello, I got Pro Tools 10 and I am using it with a Lexicon Alpha audio interface.

When I open Playback Engine in the Setup menu, I get a list of different HW Buffer sizes such as 64, 128, 512 and 1,024.

I noticed that the lower sizes give less latency when recording, however when I set it to 512 and clicked Minimize additional I/O latency, that seemed to remove the latency as well (without clicking it, I could hear latency at 512).

I would appreciate any thoughts about the right setting for HW buffer in the Playback setting dialogue. What should I set it at and leave it at, a low latency or a high one with the check box checked?

Thanks!

not something you just leave. typically 64-128 to track and 512-1024 to mix. these are variable depending on your computer power. if you can leave your machine at lower buffers do it, but most people will switch back and forth for their needs.

I see. Thank you very much, that was a big help.
