Thanks Artur,
Well. I haven't really solved the HUI latency.
But, on the other hand my system doesn't rely upon it either.
Hard to explain. :-)
I've done it so its on a second layer kind of. You can route HUI in and out any way you choose. And from any track to any track.
So it can be used to control DAW, or / and be controlled from DAW. It can also be dumped and imported between both.
It's pretty cool actually. I'm gonna do a proper demo when I get access to my old SSL.
