Thanks, this helps. Personally, I think placing this in AutomatableModel
probably makes more sense, conceptually... as the function returns
"global value of this model"...

A lot of this would be simpler if we had just one static tempo track
instead of using automations for tempo, though... might be something to
consider for the future.
