Timing_engraver

Responsible for synchronizing timing information from staffs. Normally in Score. In order to create polyrhythmic music, this engraver should be removed from Score and placed in Staff.

Properties

timeSignatureFraction (pair of numbers):

pair of numbers, signifying the time signature. For example #'(4 . 4) is a 4/4time signature.

barCheckNoSynchronize (boolean):

If set, don't reset measurePosition when finding a bbarcheck. This makes bar-checks for polyphonic music easier.

barNonAuto (boolean):

If set to true then bar lines will not be printed automatically; they must be explicitly created with bar keywords. Unlike with the cadenza keyword, measures are still counted. Bar generation will resume according to that count if this property is set to zero.

whichBar (string):

This property is read to determine what type of barline to create.

Example:

\property Staff.whichBar = "|:"

This will create a start-repeat bar in this staff only.

If not set explicitly (by property or bar), this is set according to values of defaultBarType, barAlways, barNonAuto and measurePosition.

Valid values are described in (lilypond-internals)bar-line-interface.

.

barAlways (boolean):

If set to true a bar line is drawn after each note.

defaultBarType (string):

Sets the default type of bar line. Available bar types: [FIXME];

This variable is typically read at Score level, so overriding Staff.defaultBarType will have no effect.

skipBars (boolean):

Set to true to skip the empty bars that are produced by multimeasure notes and rests. These bars will not appear on the printed output. If not set (the default) multimeasure notes and rests expand into their full length, printing the appropriate number of empty bars so that synchronization with other voices is preserved.

@end lilypond

timing (boolean):

Keep administration of measure length, position, bar number, etc? Switch off for cadenzas.

oneBeat (moment):

How long does one beat in the current time signature last?

measureLength (moment):

Length of one measure in the current time signature last?

measurePosition (moment):

How much of the current measure (measured in whole notes) have we had. This can be set manually to create incomplete measures (anacrusis, upbeat), the start of the music.

currentBarNumber (integer):

Contains the current barnumber. This property is incremented at every barline.
