Hello, Harm showed me another way to work for those slashes, using 'DurationLine', maybe it is the result of Urs work? Apparently it is a quite new feature for contemporary music. But it is very useful in my tablature example! It's in the original thread.
Thanks to Jean I managed to fix the issue with the dots, indeed, I had to remove the Script_column_engraver and then add it again after the New_fingering_engraver, not in Voice, but in TabVoice :-p. (wow, I could figure that out on my own). Thanks again for the help!, I'll take a look at the Episema grob, I didn't know of it's existence, even what was :-). grtz, Bart https://esmiltania.be On Twitter <https://twitter.com/Bart_Issimo> On Google+ <https://plus.google.com/u/0/b/116379400376517483499/> Op vr 26 mrt. 2021 om 22:10 schreef Leo Correia de Verdier < leo.correia.de.verd...@gmail.com>: > If anyone is going to attempt to create a function or engraver for adding > those slashes automatically there is a thread Urs started last summer about > Indicating duration with lines where there might be some code worth reusing > for this. > > > 26 mars 2021 kl. 21:01 skrev Jean Abou Samra <j...@abou-samra.fr>: > > > > Hello, > > > > Le 26/03/2021 à 15:23, bart deruyter a écrit : > >> Hey, > >> > >> - thanks for the idea, but after some thought, I'm afraid it won't > work.
