      What you said was not completely true.  A stock A1000 does not have
a software switchable filter. HOWEVER it is very easy to make the filter
software switchable.  A complete article of how to do it was in a 1987
Amazing Computing mag.  I will mail the person who posted the question the
volume number as soon as I find it. The switch even works with the software pro
gram LED, same as a500s and A2000s do.
Personaly, I could find no instances where I ever wanted the filter on, so I
just put two jumpers across the audio buffer chip pins that cut out the filters
there.  I still have not found a any music samples that needed filtering.

Even so, if a person was concerned about aliasing noise, they would get better
results if they used a good equalizer instead of the built in Amiga filter.
