Change visual note duration for tremolo #306

Open jacekiwaszko1 opened 4 years ago

jacekiwaszko1 commented 4 years ago

There are cases in early music manuscripts, where tremolo is notated incorrectly:

trem-vis1

System similar to !LO:N:vis would be usful in this case, eg. !LO:N:TREM:vis=. Encoding of the example above could look like that:

**kern
*clefC4
*M3/4
=
8r
8EL
8E
8E
8E
8EJ
=
8r
*tremolo
!LO:N:TREM:vis=2.
8F#L
8F#
8F#
8F#
8F#J
*Xtremolo
=
*-

Target rendering:

trem-vis2

As 5 eights are impossible to encode in MEI as dur + dots, note@dur.ges and note@dots.ges can't be filled in, I suppose?

craigsapp commented 4 years ago

Is it impossible to encode such a case in MEI, @lpugin? I seem to remember that @dur.ges was allowed to contain a list of durations, which would be additive. So in this case @dur.ges="2 8" or @dur.ges="8 8 8 8 8" could then be used.

In the current documentation for @dur.ges I do not see this as allowed:

https://music-encoding.org/guidelines/v4/data-types/data.duration.gestural.html

(or I was thinking of another durational parameter that I do not see anyway).
