Tuossa 1818:ssa on näköjään joku oma viritys latenssittomaan monitorointiin: http://www.presonus.com/community/L … e-Truth-About-Digital-Audio-Latency

Optimizing AudioBox VSL Software

AudioBox VSL monitoring software runs between the USB Bus clock buffer and the ASIO/ Core Audio buffer on your computer, so it is only subject to the latency from the USB Bus clock buffer.
 
Unlike many manufacturers, PreSonus did not fix this buffer at 6 ms; rather, AudioBox VSL offers a choice of three buffer sizes. To reduce the confusion of presenting the user with two types of buffer settings, these USB Bus clock buffer settings are labeled Performance Mode.
 
This setting is available from the Setup tab in AudioBox VSL, and it directly affects the amount of latency you will hear in monitor mixes from AudioBox VSL software.
 
At the Fast setting, AudioBox VSL runs at a USB Bus clock buffer setting of 2 ms, while Normal sets the buffer to 4 ms, and Safe sets it to 8 ms. So when you set your AudioBox VSL to run at the Fast USB Bus clock buffer setting, roundtrip latency will be approximately 3.5 ms, including the time it
takes for the A/D D/A converters to change analog audio to 1s and 0s and back to analog again.
 
To optimize these buffer settings for your particular computer:
CPU Performance Meter in Studio One 2 Artist DAW (comes free with AudioBox VSL interfaces).CPU Performance Meter in Studio One 2 Artist DAW (comes free with AudioBox VSL interfaces).
 
Begin by creating a monitor mix in AudioBox VSL and setting the Performance mode to Fast.
Listen carefully for pops and clicks and other audio artifacts at a variety of sample rates.
Now load the AudioBox VSL with compressors, EQs, reverbs, and delays.
If you hear audio artifacts, raise the Performance mode to Normal. On most machines, Normal will provide the best performance with the most stability. If you have an older machine with a slower processor and a modest amount of RAM, you may need to raise this setting to Safe. Keep in mind, however, that even at 9 ms, AudioBox VSL is running at a lower latency than monitoring through most DAWs at the best ASIO/ Core Audio buffer settingand the best buffer setting will not work on a slower computer anyway.
 
Once you have Performance mode tuned, the next latency component of the driver to tune is the ASIO buffer size (Windows) or Core Audio buffer size (Mac). This time, load a large session into your DAW and experiment with the buffer settings. Again, you are listening for pops and clicks and other audio artifacts.

 
If your DAW includes a CPU-performance meter (as Studio One does), you can use this to help you find the best buffer setting for your computer.
 
No matter how you set your ASIO/Core Audio buffer size, the monitoring latency in VSL is not affected. So you can set this buffer fairly high and lower it only when you are playing virtual instruments. Keep in mind that its still important to determine the lowest threshold at which your DAW can still perform stably.
