I have the card running in ADAT mode. 2*64 sounds terribly distorted on my
system. 2*whatever seems not to work well with any buffersize for me.
I get the best results (=12ms in/out) with sr 96000 and 4*32 (as long as i
don't move my mouse to much :-/ ) The only problem now is that osc~,
metro etc run at about half speed..
