Using Linux we have success reports of stable latency at <3ms with 10 
tracks while using this device. With 24 tracks the latency creeps up to 
<10 ms.

My advice is to learn how to use a Linux machine and then you will have 
the best of both worlds.

Being on stage with the band in front of crowds shouting, "Get off! No! 
We want normal music!", I think that was more like acting than anything 
I've ever done.
