Hi Paul.

OK - got it. I mean at least from a user perspective, by looking at
HDSPmixer, the HW-outputs seemed like single controls.
What's confusing on the first glance is that these cover a different gain
range and can be contolled independenly form the input
controls. I considered the outputs the vertical and the inputs the
horizantal layer of the matrix. Anyhow. Never mind.

Perhaps you could explain why in HDSPmixer the input group controls have a
range of -inf to +6db and the HW-outputs -inf to 0db.
