Why bother with normalized parameters then?

In AU world you specify name, min, max, default value, entity (indexed, 
dB, Hz whatsoever) and some flags like "Hi res", "Writable", "Readable" 
etc. for a parameter plus (optionally) value strings and everything is 
clear to the plug and it's outside environment.

If your process needs to have another scale than say -100% to +100%, it 
can easily transform that.

What do you think?
