Many keyboards also have a "modulation" wheel, which sends CC 1, and is
most usually bound to vibrato depth. It's nice to have it by default,
but it's also nice for patch implementors to have the ability to bind it
to something else.

Also "Main Volume" (CC 7) is often expected to control the volume
without affecting timbre. Probably fewer reasons a patch implementor
would want to change this behaivour, but still always nice to have the
capability.
