From the displayed “Digigram drivers” window,     
select the Stream granularity of the card (number       
1
of samples processed at a time). The lower the        
granularity,thelowertheaudiolatency.

A granularity of 64 samples is the default value.        
When using DirectSound/Wasapi based software    
applications, the selection of a lower value may       
produce audio dropouts, depending on the PC      
configuration.

Under ASIO, granularity can be set to the minimum        
value (8 samples), as the ASIO driver uses one        
single64channeldevice.

When using the card, if audio dropouts are       
experienced, it may be necessary to increase the       
granularity.

Granularitycanbe:8,16,32,or64samples.
