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
