Thanks Tom, some very enlightening comments -- especially about the lack of
errors.I had already noted that fluidsynth was not good at reporting errors.
I have now implemented fluid_synth_set_reverb() and of course it now works
beautifully and Iget the currently set values from value =
fluid_synth_get_reverb_roomsize(synth); etc.
It was amazingly easy once I located the proper documentation (which I had
already lookedfor but failed to find).

Reverb is a feature of the synth, you should therefore have a look at the
numerous functions the synth provides:
http://www.fluidsynth.org/api/synth_8h.html
One of those functions is fluid_synth_set_reverb(), which perfectly fits your
needs.

This assumption is wrong. Those settings are not documented because they dont
exist.
The fact that you can recall the value via fluid_settings_getnum() is due to
the error-hiding behaviour of fluidsynths 1.1.x settings API. Whenever you set
a setting that is unknown, it is silently registered. This behaviour was
recently fixed upstream and will be part of fluidsynth's next major release.
Furthermore another inconsistency regarding the settings API was addressed: all
public fluid_settings_* functions that return an integer, which is not meant to
be interpreted as bool, will return either FLUID_OK or FLUID_FAILED (rather
than TRUE and FALSE as they currently do).
Tom
P.S.: fluidsynth.org/api/ is currently down, give it 20 hours to recover.
