Your problem is related to the sound card you have. You need to find a card that supports both the ASIO2 and GSIF standard simultaneously. The hacked SBLIVE drivers may work for ASIO2 but are not GSIF compliant.
In this regard you are out of luck with the SB Live. Going with a more professional card may afford you more sucess in your endeavour.
I\'ve got Logic Audio Platinum working with GS160 in a happy combination with the Frontier Design Dakota/Montana card. By extension Cubase has worked as well. You will need at least 256MB or RAM for Cubase to try this and some fast Ultra160 SCSI drives to get the throughput you need. I used two Quantum Atlas 10KII 18.4GB drives which are \'audio/visual\' rated; meaning each drive sports 8MB of onboard SRAM. With this drive subsystem you can drive all 32 channels of audio I/O without disk dropouts!!
