It seems an attenuator with a hbit of slew might work well.  Just a 
one-pole filter would do pretty good, or a single CyIndustries 
Lowpass Gate (from the quad)....  Then you would get better 
resolution (or quasi-resolution, as it were) and not have to 
attenuate everything quite as much (in case you wanted a wide-assed 
sweep range)....  owning cakes and eating them too anybody?
