I am afraid I don't fully understand it myself :-) , and the manual is rather sketchy on this... Both settings are located on the Audio:Drivers page. The I/O buffer, set as 32, 64, ... 1024 samples, is probably the one you were talking about. It is used by audio hardware (p. 378 of the manual). The processor buffer set as small, medium or large (p. 380) is "the native buffer used to compute mixes and effects", and to my surprise it also affects the latency, especially with processor heavy plugs. It's the I/O buffer that we increase when mixing, that's why I posted the comment above... My personal understanding is you don't mess with the processor buffer once you found the optimal setting... I would really appreciate it if someone could explain it in greater detail. Best, Andy
