Generally, for MIDI sequencing, velocity is used to control volume for
single notes that don't change (like an acoustic piano or percussion
instruments) -- the loudness of the note will remain the same for the
entire note. You really want to use expression (CC#11) for instruments
that can change loudness over the course of a note (like a dimenuendo
or crescendo in a string section), and volume (CC#7) is best used to
control the overall volume of the entire track (like would be used in
a volume slider on a mixer). Many playback synths (especially
samplers) will have different recorded sounds playback based on the
velocity, so when you play a ppp you will get a note that has a
different sound quality than a note played at fff. You don't get this
using volume or expression.
