This audio interface’s main task is to convert digital USB signal to optical one with ability to output high-quality analogue signal via headphones ports. For its tasks it is very good; but if there is need in more functional external sound card for wider range of tasks ( high-quality analogue signals recording, MIDI ports support, high number of analogue outputs and other functions ), then it is better to buy one of Steinberg, Behringer, Focusrite, Roland, ESI, M-Audio itself or other manufacturers production.
