Audio interfaces with flexible virtual mixing Options

[markanini]

By using Direct I/O in the US-800 driver, audio signals can be exchanged between applications that use different interfaces. Using this function, the following types of operations are possible.

Record the playback sound of a multimedia player into a DAW that uses ASIO.

Record the output of an ASIO DAW into a WDM application.

Send the US-800 input signal to a WDM application.

This functionality is quite rare. I it find it useful, I can connect Windows output to a ASIO host and thus apply system wide audio processing. It also came in handy when I couldn't get my head around how to export mixdown of a session when I tried a sequencer, forgot which now...

Here's an incomplete list of interfaces that have this functionality:
ESI Maya44, U46, Duafire
Infrasonic Quartet
E-MU 0404, 1212m, 1820, 1616m
Tascam US 800

Keep in mind some are discontinued and native PCI support is quickly disappearing.

Feel free to comment and If I forgot an interface let me know.
