Hi James,

Thanks for the suggestion, but I believe you are talking about something  
different than I meant. This property in articulate.ly simply changes the  
proportion of which note should have its value stolen by the grace notes.  
In old music, for instance, you tend to play graces before the beat, while  
more contemporary scores normally ask them to be on the beat (this rule of  
thumb vary greatly for both cases and you will find counterexamples  
everywhere). That said, my request was to be able to control the total  
duration of a grace. So for instance, if I want to have in the score  
\grace{c'16}, its duration will always be that of a c'64 regardless of  
which note it's stealing time from. My current workaround is to use \grace  
\scaleDurations 2/1 {c'16}, which will sound as a c'32 (twice the expected  
value). It just would be nicer to be able to set this for the whole score  
and avoid the verbosity of using scaleDurations for every grace note.

Thanks again and take care,
Gilberto
