With Gstd160 2.2 use E-WDM 1.31 driver. It allow to stream directely the 8 outputs to 8 new created ASIO inputs if you launch and use Audio Sequencer like LogicAudio or Cubase. It´s called GigaWire. I am able to record directely 8 tracks in LogicAudio + normal audio tracks at the same time without problem.
With 2.0 use the last no E-WDM driver (1.9)
Take a look to the online Egosys Docs and FAQ.
Hope it helps you too.
