Velocity, depending on the synth can actually trigger a different sound, so it is important to realize that while velocity is often used for volume (within the synth patch itself) it can also serve other purposes. Example; an bass patch that uses finger strum on lower velocity but changes to a plucked string (pop) at higher velocity.

Anyway, the answer to your original question on making volume sliders move inside RB is CC7. If you used velocity you may change the actual timbre of the sound instead of just lowering it's volume.

Think of it this way; velocity equals how hard you hit the keys on a synth and volume equals how loud the synth is turned up (or down)
If the synth overall volume is low, hitting the keys harder will not increase the sound above the master volume of the synth. Instead it is attenuated by the volume (CC7) of the synth or track.

I do not work here, but the benefits are still awesome
