The midi dynamics don't work properly, and never have. They adjust
the volume, but not the velocity, and they always apply for the full
duration of a note. This means that when played through a half-way
decent synthesizer, the different tones for the different dynamics do
not come through. For example, a clarinet played loudly has a buzz
that isn't there when it's played softly --- it's not just a volume
change.
So for example,
{
\set Staff.midiInstrument = "clarinet"
c1\f\> c1\!
}
plays the first c forte then the next one piano. There's no
decrescendo on the first C. And no way to say, stop halfway.
I have to do things like this to get the visual effect I want:
<<
{ c1 } \\
{ s16\f\> s16 s8 s4 \! s2}
>>
and that doesn't do the right thing in the MIDI output.
