Re: Making feathered beams more variable

[Thomas Morley]

Hi David,

to get beaming consistent to your featherDurationTest, I added a new condition to my grow-beam-var:
With a positive argument you retrieve accel.-rit.
With a negative one rit.-accel.
(Most of the testing is commented out and the turning-peak option is deleted)

I added your revised featherDurationTest to the file. But when trying to compile the whole testing with it, I had to interrupt after a minute without result. So I commented the revised version and used the older one.

I tried to make an automated definition (first attachment) and to integrate
it in the grow-beam-var-definition (second attachment). This feature will
only work with kneed beams and if the directions of the first and last stem

But I noticed a strange behaviour: I retrieve wrong output if the
global-staff-size is changed, or with other changes. Can you confirm this?

Perhaps it is similiar to my problem with your
center-grob-between-definition.
Or am I missing something or doing something wrong or ...?

 

I see no problems with the knee-beamed group on a single staff.  However, running your files, exactly as you sent them, on 2.14.2, I see no shortening of the final stem in the cross-staff examples.  Oddly enough, when I change the global-staff-size, the last stem of the last cross-staff group IS shortened at some sizes, but the other final stems are not shortened at all, ever, whatever size I try.

 

Also, I deleted my attempt to automatize stem-shortning (for now stems are to be shortened manually. This works! :)). Perhaps I start a new try with "2.15.13" and the 'length-property next weekend.

I really have no idea what could be causing these differences between our machines... A difference in OS?  Is this even a reasonable speculation?  (I'm using Windows XP.) 

 

I compiled your old centerGrobBetween_rev2.ly again with "2.15.13" and I never get warnings or wrong output. So I think it's not a problem of OS (I'm using Linux Ubuntu 10.04).
Well, I speculate, but could it be a problem with the Linux-version of LilyPond "2.14.2"?

 

Sorry I can't be of more help...

Your help is great!!!

Many thanks,
  Harm
