I highly recommend to use `ajmidid -e` with jack2 to directly expose the
hardware device via jack-midi.

Odd. there should be no need for that. CC7 is by default assigned to the
volume control knob. This default is hardcoded in the source [1].

Maybe you have a custom config that overrides this?
~/.config/setBfree/default.cfg or a file in /usr/share/setBfree/ ?

you could run the headless version and ask it to print CC bindings:

  setBfree --dumpcc

That would also show "loading cfg: ..." in case a custom file is read.

Anyway, I'm glad you got it to work. Have fun with the Hammond.
