Windows
The DUO-CAPTURE EX supports two standard Windows driver protocols: ASIO and WDM.
- ASIO: Due to the industry standard nature of ASIO drivers, the DUO-CAPTURE EX can't be used with another audio interface simultaneously on a Windows computer when selecting ASIO as the driver mode.
- WDM: The WDM driver protocol allows for multiple audio interfaces to be used simultaneously. Check the documentation of the audio software that you're using to determine if it's compatible with WDM driver mode and, if so, how to setup multiple audio interfaces using WDM drivers.
Mac OS X
The DUO-CAPTURE EX can be used with another audio interface simultaneously on a Mac OS X computer by creating an aggregate device to use multiple audio interfaces simultaneously. The following article guides you through creating an aggregate device and then setting it up in audio software:
