Hurray a question! (slow weekend...)

Hi Juergen and all,

>Lot about it in the archives ...

I checked these already, and I found quite a lot of stuff, including a
lot from me and you a couple of years ago. But not the basic reason why
the manufacturer's apps don't contain the diodes for the filters, but do
for the VCAs.

>Want clean until suddenly clips - use diodes. Want gradually increasing
harmonics - don't use diodes.

This is true certainly. So I wonder if it is to do with the input pd
range the filter will expect. VCAs have a top headroom defined, and we
can all work with that. But filters have too many variables, so this
makes the soft clipping more useful... and perhaps, more musical.
