I think that is actually a good way of implementing global tuning. It
would be good to let the host provide the figure and the instruments can
just pick it up. There may be reasons for particular values in particular
hosts or styles. We could recommend Concert A as a default, as thats how
most synths are tuned in my experience.
Modular synth style modules generally ignore the global tuning anyway.
They have there own 0.0v -> Hz mapping, set via a dial.
I dont see any point in specifying it as middle C.
