I did consider doing it this way over the weekend.  However, being able
to adjust the relative volumes of the different channels still seems
useful to me.  If you have a single unified control, then you mess up
trying to move the others.

What do you think?  Should I just slave them all together and remove
the other volume controls?  It's probably easier; it just seems somehow
lacking.
