Some Lily features can be globally turned off by an off statement in
the score section, and/or an off statement in the print section,
and/or by removing the engraver. For example
\score{\property Voice.pletVisibility=0}
or
\paper{\translator {\VoiceContext \remove Tuplet_engraver;}}
but
\paper{\translator {\VoiceContext beamAuto = 0;}
or
\paper{\translator {\VoiceContext \remove Auto_beam_engraver;}}
(hope I've got those right :)
Which method would you recommend to best hold up across future
versions? Removing the Tuplet engraver produces a blast of error
messages, but it works fine for Scarlatti...
