Hi Paul, Alexander et. al! I need to be very short as a rehearsal is waiting.
I'd advocate to keep minimum-length. I also need some way to force an extender and to inhibit extender generation. Forcing an individual extender should overrule a general inhibition of extenders. Details can be hidden by some music functions ... but there's not time to generate a patch now. Have a look at the attached ly and the generated pdf ... and comment on the chosen names and syntax. It should be self-explanatory. cu, Knut
