Re: slightly OT question about midi rendering

[Richard Schoeller]

What I've found in regard to \tempo is that it either works in the
\score block that is generating the midi or if it is referenced in every
single staff.  If you want the tempo to change in the middle of the
piece you have to use the latter approach.  I do this by having each
staff include one or more really voices and a "metronome" voice.
