Ok, sorry for the bottom quote, but I'd like to get the context into the
developer list.

Shouldn't we have a command

\transposing f { ... }

(better naming suggestions welcome) that does transposition and Midi
correction in lockstep?  Is anybody willing to count how _often_ this
question pops up, and how often people get confused trying to get score
and Midi to look and sound right?

It is not all that hard to explain, but it is one thing that new users
and helpful experienced users should not be wasting hours with.  And
make no mistake, they are.
