The Buffer Size (Windows only) option box contains a number of predefined sizes in its drop-down menu, or you may type in
a value. Depending on the setting, the driver may round the value and the current Operation Mode will enforce limits on the
buffer size, so the resulting value may not always be the same as what is entered.
The Operation Mode enforces buffer levels which help prevent performance-related dropouts when using audio on computers.
The higher the Mode number, the less chance of audio artefacts, with the sacrifice of increased system latency. Dropouts are
caused by the configuration of the computer, and also by what other applications are running at the time, and lastly by the
worst-case DPC latency caused by other drivers. Network drivers, for example, are a notorious source of latency on an
otherwise high-performance computer.

The WDM tab (Windows only) can be used for enabling or disabling the Windows Driver Model audio channels, configuring
them as mono, stereo or surround, depending on your computer’s capability, and mapping the WDM channels to the required
channels on your GS-R24. For example you can map the stereo WDM channels to the master L-R channels (31-32) on your
mixer so that your computer CD player and general audio will be played to the Master L-R channels for monitoring.
