iConnectivity iConnectMIDI2+ Owner's Manual page 18

If you are using the iConnectMIDI 2+ alongside other audio interfaces installed on the
Windows computer, as shown above, they are automatically "aggregated" into what
appears to the software as a single interface with combined number of outputs in each
one.
This is automatic when you select the ASIO4all driver. Whether the iConnectMIDI 2+ 's audio
I/Os are numbered before, after, or in between other interfaces connected to your
Windows computer may be arbitrary.
