After more tinkering, it seems that the min/max values are only applied
if a dynamic is added to every explicit voice within an instrument's
music. This seems to act as an "initialisation": subsequent dynamics
within the Dynamics context are applied.

By way of a workaround to generate usable engraving and midi files from
the same source, is there a way of making the (additional) in-voice
dynamics disappear without affecting the Dynamics dynamics?
