In addition, your pedal is probably sending expression messages (CC11)
by default.

Just as an aside: when I code a (de)crescendo in MIDI, I use a
combination of velocity and expression. Velocity, as said before not
only influences the relative perception of volume but also changes the
timbre of most instruments. I only ever adjust volume (CC7) for mix
purposes on an over-all basis, never as a continuous controller.
