2.2.14 Beat_performer
This performer is intended for instantiation in ‘Voice’-like
contexts. The context variable beatExtraVelocity
is used for adding extra MIDI velocity at each beat (default 15) in
accordance with beatStructure
and an additional
barExtraVelocity
(default 10) at the start of each bar.
This is done by adding corresponding \accent
and
\marcato
events when such note events are encountered.
Off-beat manual use of \accent
or \marcato
causes
autogeneration of the next on-beat accent to be skipped.
Music types accepted:
articulation-event
and note-event
