articulate.ly script

[Andrew Bernard]

I'm new to MIDI work with LilyPond (new to MIDI with LilyPond, that
is, not new to LilyPond). Attempting to apply the articulate command
from articulate.ly, why does this example output rests after the
notes? Without wrapping the music in \articulate it is of course fine.
I'm missing something fundamental.
