I just tried this with the latest fluid from git and after sending an
MTS mid file with pmidi (the method that works for timidity), I see the
control changes in the console, but dumptuning 0 0 shows the default
12TET tunings.

In my case, that's the reason I don't settle for timidity. The
interpolation is much worse.

Your answer didn't solve the problem, but it's still helpful as far as
I'm concerned.
