The Midi backend is pure C++, not accessible to Scheme programming and
not even using Scheme garbage collection.  That would be good to change
some day, but that's a long-term perspective without currently ongoing
or even started work, and without a Scheme way into _any_ Midi,
generating arbitrary Midi bytes just does not appear to make a lot of
sense as they could not be usefully serialised.

One could conceive of a few special-cased "performers" that could pick
up data of certain kinds (generic controllers or stuff?): that kind of
thing might actually work without opening up Midi to Scheme in general.

But at the current point of time, there is nothing implemented, and more
importantly there is absolutely nothing you could do without going to
C++ first.
