I think I understand why these errors are generated. It would appear
that \fz is not intended to be used as a dynamic - it is not
mentioned in the NR. Nevertheless, is is defined as a dynamic script
in the LP file dynamic-scripts-init.ly. Unfortunately, there is no
corresponding entry in midi.scm to assign a “factor of total volume”
for this dynamic, without which the midi performer is unable to do
anything sensible.
It is possible you might get the results you want by rewriting the
snippet as:

Good idea; thanks for the suggestion. I'll give it a try over the
weekend, once I've worked out the ramifications for other tags in use.
