However, I'm wondering if there is some way to add the continuous drone
to the music automatically without having to actually write them in as
separate voices? I need two separate drone voices sounding the same note
continuously during the entire playback.
One option would be using a MIDI editor to add the drone tracks.
SpeedyMIDI is what I would use for this.
<http://speedymidi.sourceforge.net/>
Add new track, get the mouse-keyboard, set the drone notes, and mash the
spacebar until the duration's been recorded to desired length.
There might be a Scheme method, though. Things I've looked at here:
display-scheme-music
#(display (ly:music-length ...
\scaleDurations stuff

I finally decided I was playing "sorcerer's apprentice" with those. But
in the past, I've been able to provoke a correct answer by posting an
incomplete or incorrect one. :)
