Although we recommend using the default settings, it may be useful to set the Process
Buffer Range parameter to Large in order to avoid disturbing the DAE’s calculation of
TDM audio tracks. Changing this setting will aid system performance, allowing the
playback of the maximum number of audio tracks to remain achievable. You should
only activate the 64 Busses feature if absolutely required. When disengaged, you will
reduce the strain on the CPU, which frees up resources that can be used for native
instrument and plug-in processing.
Note: Further information on the parameters of the Drivers pane can be found in the

hardware. For more information, see “Generate Audio Mixer” on page 19.
