Virus Control and Multiple Audio Devices

[horsegrip]

Here is my problem and hoping Access Music can rectify the problem.

I'm running a mac with a Tascam DM3200 digital mixer (Firewire Interface).
I have spoken to the support team and they can't help with the problem.

I want to use the Virus control. It works in stand alone, but once used with a sequencing software e.g. Cubase 4, fails to work.
The reason is that my DM3200 is the sole audio driver. Mac can have Audio Aggregate, but the latency is as the slowest audio driver.
Access is aware of this, but can't deliver. I would like to see the option of using USB Virus Control, without using it as an audio input but instead using phono outs.
This will then give users like me $$ use out of the TI and use the attractive Virus Control Centre
