Indeed, in 4/8 the beat (baseMoment) is 1/8 not 1/4

True as well, beatStructure in 4/8 is '(2 2)
So below works as expected:
\new Staff \with { \consists "Measure_grouping_engraver" }
{
\time 4/8
a'4 4
}
Though, there is another not yet mentioned point.
MeasureGrouping also relies on the actual music rhythmically matching
the beatStructure.
\new Staff \with { \consists "Measure_grouping_engraver" }
{
\time 4/8
a'2
}
Will print only one bracket.
To get two brackets a second voice could be inserted, easily:
\new Staff \with { \consists "Measure_grouping_engraver" }
<<
{ \time 4/8 a'2 }
{ s4 s }
>>
No bug I'd say, but likely worth explaining.
Though, why is the a first bracket printed, even if no music
rhythmically matches the beatStructure?
See 3rd measure of:
\new Staff \with { \consists "Measure_grouping_engraver" }
{
\time 4/8
a'4 4
a'2*7/4 a'8
|
}
That I can't explain.
Others?
Cheers,
Harm
