That's a good point.

However, they can be controlled independently for everything *other*
than sample rate.

I'll have to ponder your point carefully and take it into consideration
for what i decide to do when i push out a patch (hopefully one that
will get accepted this time :-) )

But for our *product platform* the independent control is a must
have, so i am kinda stuck solving this problem somehow, someway.
