Don,

It was my decision to remove them, for the reasons given below. It's 
trivial to add them back in, but debatable as to whether it's a good 
idea. I'm open to discussion. Perhaps we could put them back in along 
with cautions in the manual.

Please send me a description of how you would use the controls, i.e. 
the qualitative effects you have in mind or specific decay values 
you've used before, etc. I'd like to evaluate how your needs differ 
from the nominal settings already present.

Here's my reasoning for removing some of the controls:

1. Months of field testing revealed that our testers -- despite a wide 
variety of operating styles -- barely ever changed any of the settings 
except flatness and hold (hang) time.

2. Some combinations of settings can end up being very confusing, 
except for the advanced and/or experimentally inclined operator who can 
recognize the side effects. This has been endlessly played out on some 
of our competitors' rigs. I had sought to avoid such difficulties once 
it became clear that there was such a small range in use by our 
testers.

3. Some settings can compromise the performance not just of AGC, but 
that of other functions, as well (e.g., DSP noise blanking and AGC 
pulse detection/removal).
