That's what we have amplifiers for.

I recorded the entire MIDI in one wave so I had to make sure nothing would play so loud that it created clipping. I'm not a big fan of normalizing stuff after recording as it makes soft pieces sound very loud compared to the more loud pieces.
I read that when chosing the musical selections for for
Fantasia, Walt Disney and Leopold Stokowsky listened to days and weeks worth of music.
Walt had the bad habit of turning up the volume on the low, quiet sections and lowering the volume on the loud sections.
Finally after a while of this, Leopold sternly admonished him, "The parts that are quiet are SUPPOSED to be quiet, and the parts that are loud are SUPPOSED to be loud."
Uncle Walt left the volume alone after that...
