You can change the ASIO
buffer size within the DAW
set up pages. You cannot change the Firewire buffer size when the DAW
is running. This can be done by going to the Windows Start menu > All Programs > Focusrite Saffire Pro > ASIO
The firewire buffer size determines the step size of the ASIO
buffer choices. For example a firewire buffer of 4ms means that the ASIO
buffer can be set to 8, 12, 16, etc ms.
Older, slower computers will require larger firewire buffers sizes to prevent break up in the audio playback.
