Boss GT-Pro set-up in SX3?

[Superhuman]

Another stupid question... I've got my keyboard and Mackie Hui setup - no problem. I'm using an outboard Delta 1010 soundcard. How do I set up my GT-Pro for direct recording via USB? I have it set up alright and installed on my system - it talks to it's editing software and is listed under the Device menu but I can't for the life of me work out how to get any sound out of the damn thing. Anyone out there know how to tweak the settings under Devices to make this work while not disabling the Delta as the main ASIO driver for playback?

It probably works along the same principals as a PODxt or any other USB guitar processor...

Problem sorted... as in I found out that the problem can't be sorted. If any of you have a GT-Pro and you want to record into Cubase the only way to do it is either direct line in or through SPDIF...
