well, i guess, this is mathematically correct, if complete silence would
start at db ;)
i usually scale the midi range 1 to 127 from the lowest audible sound to
the loudest i want to produce, which works pretty good for my ears,
except the fact, that 7 bit are just too little for an accurate volume
control (at least for my ears).

The only people for me are the mad ones, the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn,
burn, like fabulous yellow roman candles exploding like spiders across
the stars and in the middle you see the blue centerlight pop and
everybody goes "Awww!
