That's also what I'm trying to achieve but it doesn't always seem possible
with LilyPond only. I like having separate input files for the different
instruments, but for most projects, I don't think it would be wise to go
further and put other tools in the picture such as a preprocessor that would
fetch its data from a database!

E.g. in this instance, I would have liked to keep the drone notes and the
melody notes together (i.e. in the same file) because they both are the
bagpipe "content".
But that, as we've seen, that makes it difficult to separate the printed
from the midi output; hence I had to *separate* contents that belong
together (i.e. create the "drone" staff) and then use "\tag"...

Of course, that's also what I do.
But having the "drone" and "melody" in separate voices is not enough; they
had to go in separate staves. Otherwise I would have mixed contents (music)
with layout decision, by specifiying a "\tag #'no-layout" in front of the
drone "Voice"!

Anyway, in the end, it works, with minimal changes :-)

Best,
