Exact stem length?

[Urs Liska]

Hi,

I'm trying to recreate a contemporary notation. Attachments show my 
results so far, of course I'd want to encapsulate that in a function 
later to have it accessible.

The problems I have (apart from the slash that is still missing):

- How could I remove the gap between the first two stems?

- Is there a way to get the stems extactly the same length so I can get 
an even distribution regardless of the length of the expression and the 
beam's slope?
Currently the stems seem to respect the vertical position of the 
non-existent noteheads.
I tried to set the Stems' length and the vertical position of the 
notehead, both didn't do anything.

For a final function I would like to give the following parameters as 
arguments:
- First and last pitch
- rhythmic extent of the group
- number of "notes"
- length of trailing rest (i.e. ratio of the visible group to the empty 
rest.

Any ideas?
TIA
Urs
